[Amended 1975; 1980; 2017; 2018]
Except as provided in §
240-4.4, every lot shall conform to the dimensional requirements set forth in §§
240-4.2 and
240-4.3, and no building or structure, except fences six feet or less in height, in any district shall be built, located, enlarged or structurally altered which does not conform to such dimensional requirements.
A. Small accessory shed exception. A reduction to one-half of the values shown in §
240-4.2 for minimum required side and rear setbacks in the Residence A, B and C Districts shall apply to small accessory sheds provided that they meet the following criteria:
(1)
The shed meets the minimum required front setback requirements shown in §
240-4.2;
(2)
The shed is not permanent in nature (i.e., not on a foundation);
[Amended 4-25-2023 ATM
by Art. 23]
(3)
Its area is not more than 250 square feet;
(4)
Its maximum height is 1.5 stories to allow for a pitched roof,
and its height shall not exceed the distance to the nearest lot line;
(5)
The shed shall not be used for the parking or storage of automobiles;
[Amended 1973; 1979; 1980; 1983; 1991; 1995; 1996; 4-25-2023 ATM by Art. 23]
[Amended 1979; 1980; 1991; 1996; 2009]
A. Land located in a way, whether public or private, shall be excluded
in computing any lot area.
B. In the case of a lot abutting more than one street, the minimum requirements
as to setbacks from the street sideline shall be applicable with respect
to each street.
C. In the case of a lot abutting more than one street, the lot must
have the entire required minimum frontage on one of the streets but
need not have it on more than one.
D. Height exceptions. Churches and municipal buildings may exceed the
height limitation. Domes, cupolas, and other ornamental features,
chimneys, ventilators, skylights, tanks, bulkheads, machinery, and
other accessory features which are required above roofs may exceed
the height limitation.
E. Corner obstruction. In all districts, no building, fence or other
structure shall be erected or installed, and no tree, shrub or other
growth shall be planted or permitted to grow or exist, which will
dangerously obstruct the view of traffic by operators of vehicles
at street intersections.
F. Number and location of dwellings on one lot. The number and location of dwellings (dwellings in this section including accessory buildings) on any one lot shall be such that every dwelling thereon can be provided with sufficient land to form a separate lot which will itself be in full conformity to the regulations of this section and on which that dwelling will be in full conformity thereto; and upon alienation of any dwelling, it shall be provided with such a lot and every remaining dwelling on the original lot shall be left capable of being provided therewith. This section shall not apply to multidwelling projects in a Residence EA District for which a special permit has been granted pursuant to §
240-5.6.
[Amended 4-25-2023 ATM
by Art. 23]
G. Dwellings in business districts. No dwelling shall be erected on a lot in a business district unless the dwelling and lot conform to the dimensional requirements for Residence A as set forth in §
240-4.2.
H. Location of farm buildings. In a residence district no farm or poultry
farm building shall be placed within 100 feet of the street sideline,
except that a permanent building or structure used solely in connection
with selling or offering for sale of farm products may be placed not
less than 30 feet from the traveled portion of the street adjacent
thereto.
I. Common driveways. Common driveways serving more than two building
lots shall require a special permit from the Planning Board. Minimum
requirements are that they be constructed in compliance with the Sherborn
Driveway Bylaw, and each lot so served must have a common maintenance
agreement recorded at the appropriate registry. Common driveways in
existence and use as of September 30, 1995, shall not require a special
permit unless the use is extended to one or more additional building
lots.
[Added 1987; amended 1994]
A. Special permit required. Persons seeking relief from the minimum street frontage requirements of §
240-4.2 for any lot in a residence district may petition for a special permit granting same. For the purposes of this section, the lot having less than the minimum frontage required by §
240-4.2 is the "Section 4.4 lot." The remainder of the original lot must comply with §
240-4.2 (both before and after division) and is the "complying lot." No permit shall be granted under this section which does not result in both a Section 4.4 lot and a complying lot.
B. Grant by Planning Board. The Planning Board shall be the special permit granting authority for special permits authorized hereunder and shall hear and decide all properly submitted applications in compliance with the time limitations and other procedural requirements specified in Chapter 40A of the General Laws, this Zoning Bylaw (including without limitation §
240-6.2) and the Rules and Regulations of the Planning Board.
C. Board of Appeals comment. The Board of Appeals shall be the review
board on all applications under this section. The Board of Appeals
shall make such recommendations on each application as it deems appropriate,
and shall send copies thereof to the Planning Board and the applicant.
The failure of the Board of Appeals to make written recommendations
within 35 days of receipt of an application shall be deemed to be
lack of opposition thereto by the Board of Appeals.

C. Applicability:
(1)
Open space subdivisions are allowed by right under zoning and may be proposed anywhere within the R-A, R-B and R-C Districts. Open space subdivisions shall be subject to the requirements of the Sherborn Zoning Bylaw except as noted otherwise in this (§
240-4.5) section and the Subdivision Rules and Regulations of the Sherborn Planning Board as applicable.
[Amended 4-25-2023 ATM
by Art. 23]
(2)
Subsection
A above applies only to subdivisions of land as defined in MGL c. 41, § 81L, and not to construction of homes on individual house lots that existed prior to the date of adoption of this bylaw, or to house lots created through the "approval not required" (ANR) process with frontage on public ways in existence at the date of adoption of this bylaw.
(3)
All subdivision applications received after the effective date
of this bylaw shall comply with the provisions of this open space
subdivision section, unless the Planning Board allows a development
that deviates from the requirements of this section by special permit.
Such deviations, including conventional subdivision designs, may be
approved if the applicant demonstrates that the proposed alternative
development configuration provides protection of the site's environmental
resources and fulfills the purposes of this section as well or better
than an open space subdivision.
[Amended 4-25-2023 ATM
by Art. 23]
(4)
If the proposed open space subdivision involves a special permit(s)
for one or more common driveways, or any other use that requires a
special permit, the proceedings for all such special permits and the
site plan review for lot configuration shall occur in one consolidated
special permit proceeding before the Planning Board.
D. Yield: allowable dwelling units.
(1)
Number of dwelling units allowed.
(a)
The base maximum number of residential units allowed in an open
space residential subdivision is calculated by a formula based upon
the net developable acreage of the parcel. This formula takes into
account site-specific development restrictions and limitations that
make some land unsuitable for development, or less suitable for development
than other land. This calculation involves two steps, calculating
the net acreage and dividing by the minimum conventional lot acreage
in the zoning district.
(b)
To determine net acreage, subtract the following from the total
(gross) acreage of the parcel:
[1]
Half of the acreage of land with slopes of 20% or greater;
[2]
The total acreage of land subject to easements or restrictions
prohibiting development, lakes, ponds, vernal pools, 100-year floodplains
as most recently delineated by FEMA, Zone I and A around public or
private water supplies, and all wetlands as defined in MGL c. 131,
§ 40, and any state or local regulations adopted thereunder;
and
[3]
Ten percent of the remaining site acreage after the areas of
Subsection (D)(1)(b)[1] and [2] are removed, to account for subdivision
roads and infrastructure.
(c)
The factors named above are included for net acreage calculation
purposes only and do not convey or imply any regulatory constraints
on development siting that are not contained in other applicable provisions
of law, including this Zoning Bylaw.
(d)
The maximum number of allowable dwelling units in an open space
subdivision on the parcel is determined by dividing the net acreage
by the required acreage for a house lot in the zoning district. Fractional
units shall be rounded down to the nearest whole number. The required
acreage for each district is:
District
|
Required Acreage per Unit
|
---|
R-A
|
1
|
R-B
|
2
|
R-C
|
3
|
(2)
"An open space subdivision shall have no more residential units
than the number of units that would be allowed in a conventional subdivision
on the parcel of land that is the subject of the application, documented
by a conventional subdivision general layout as defined in the Planning
Board Rules and Regulations, submitted by the applicant."
(3)
Parcels in more than one zoning district. For parcels in more
than one district, the allowable residential unit count for each district
shall be computed separately first. These unit count totals shall
be added together and then rounded down to the nearest whole number
as above.
E. General requirements:
(1)
Open space subdivision layout. The developed areas and protected
open space shall be placed within the parcel in a manner that best
fits the characteristics of the land and the purposes of this bylaw,
in particular the protection of clean groundwater resources and environmental
resiliency.
(2)
Housing types.
(a)
Subdivision residential dwelling units shall be single-family
structures. Duplexes may be allowed by special permit, if designed
to resemble single-family homes. Duplexes will be considered as two
residential dwelling units.
(b)
Single-family structures or duplexes will be located on individual
lots. Condominium arrangements on a shared lot, or a combination of
individual lots and shared condominium lots, may be allowed by special
permit in cases where such arrangements best serve the conservation
purposes of this bylaw on the specific parcel.
F. Dimensional requirements: With the exception of building height, the dimensional requirements of §
240-4.2 of this bylaw do not apply to open space subdivision developments. Lot size and shape, residential unit placement, lot width, and other dimensional requirements within an open space subdivision are subject to the following guidelines and limitations:
(1)
Objectives. Residential units shall be located and arranged
in a way that advances the open space and resource conservation objectives
of this bylaw, i.e., to protect: views from roads and other publicly
accessible points; farmland; wildlife habitat; large intact forest
areas; hilltops and steep slopes; ponds, wetlands and groundwater
resources; and other sensitive environmental resources.
[Amended 4-25-2023 ATM
by Art. 23]
(2)
Monumentation. Monumentation of a type consistent with the use
of the open space, and approved by the Planning Board, shall clearly
delineate the boundaries of the protected open space in a manner that
facilitates monitoring and enforcement.
(3)
Area. There is no required minimum lot size for zoning purposes.
The limiting factors on lot size and placement for each single-family
structure or specially permitted duplex in an open space subdivision
are the need for 1) adequate water supply and sewage disposal for
each residential unit, 2) protection of the quality and quantity of
current and future groundwater resources on abutting properties, 3)
prevention of negative impacts on wetlands on or near the subdivision,
and compliance with the other provisions of this bylaw.
(4)
Infrastructure. Board of Health regulations regarding water
supply protection and the disposal of wastewater, and Conservation
Commission regulations regarding wetland protection, shall apply.
Protection of clean water resources will be a primary factor in Planning
Board decisions regarding placement of residential units and overall
subdivision design. For any proposed subdivision design, in particular
layouts that may require clustered or shared septic systems, the Planning
Board shall forward concept sketches and/or preliminary plans to the
Conservation Commission and Board of Health for comment. Clustered
or shared septic systems are likely to require setbacks greater than
standard single-family systems to prevent negative impacts on wetlands,
drinking water wells and groundwater, or environmental resiliency,
and therefore may require specific analyses to help determine such
setbacks, and subsequent monitoring to determine their effectiveness.
(5)
Frontage and vehicular access. Open space subdivision lots have
no numerical requirement for lot frontage. Any open space subdivision
lot must have functional vehicular access only to the internal subdivision
road. Vehicular access via a common driveway to an internal subdivision
road (but not to an existing road) may be approved by special permit.
Open space subdivision lots that have frontage on an existing public
road must maintain a wooded or appropriately vegetated buffer zone
between the existing road right-of-way and the subdivision buildings,
of sufficient length and depth to visually screen the buildings on
that lot and preserve the scenic quality of the road.
[Amended 5-15-2021 ATM
by Art. 14; 4-25-2023 ATM by Art.
23]
(6)
Setbacks. The minimum setback of any building from an existing public road shall be 100 feet. The minimum setback of any building from an internal open space subdivision road shall be 30 feet. The minimum setback of any building from the property line of an abutting property not part of the open space subdivision shall be 60 feet. The minimum distance between residential buildings within the open space subdivision shall be 30 feet. The minimum distance between an open space subdivision residential building and an abutter's residential building shall be 100 feet. Accessory sheds as defined in Zoning Bylaw §
240-4.1A shall be allowed, provided that they are at least 10 feet from the adjacent internal subdivision lot line, and set back from the lot lines of abutting nonsubdivision properties as specified in §
240-4.1A.
[Amended 4-25-2023 ATM
by Art. 23]
G. Open space requirements:
(1)
Minimum area.
(a)
A minimum of 60% of the total gross acreage of the land area of the open space subdivision shall be set aside as permanently conserved open space. At least half of the open space shall be "uplands" as defined in Subsection
B.
(b)
No more than 10% of the required open space may be utilized
for common water supply wells and associated infrastructure, subsurface
leaching fields and other underground components of wastewater systems,
rain gardens, constructed wetlands, and other decentralized stormwater
management systems consistent with low-impact development, that serve
the open space subdivision, provided that the land so utilized is
contiguous with undisturbed area(s) of protected open space. Treated
stormwater may be discharged into the protected open space as part
of an approved low-impact stormwater management plan. All protected
land must be shown on approved plans.
[Amended 4-25-2023 ATM
by Art. 23]
(2)
Contiguity of open space. Preserved open space shall be contiguous
to the greatest extent practicable. Noncontiguous areas of open space
may be allowed if they are shown to provide better protection of areas
of high conservation value or to provide continuity with open space
on adjacent lands. In such cases, applicants shall attempt to connect
these resource areas to the greatest extent practicable through the
use of vegetated corridors. Open space will still be considered contiguous
if it is crossed by a shared driveway, roadway, or an accessory amenity
such as a paved pathway or trail, as long as a functional wildlife
corridor is maintained. If the open space is maintained for agricultural
uses, open space areas will be considered contiguous if separated
by a barn or storage shed.
(3)
Permanent conservation of the required open space.
[Amended 4-25-2023 ATM
by Art. 23]
(a)
Any land required to be set aside as open space, voluntarily
preserved in excess of that required, or conserved as a condition
of site plan approval, shall be permanently protected pursuant to
Article 97 of the Articles of Amendment to the Constitution of the
Commonwealth of Massachusetts or a perpetual restriction under MGL
c. 184, §§ 31 to 33. Unless conveyed to the Conservation
Commission, the required open space shall be subject to a permanent
conservation, watershed, or agricultural preservation restriction
conforming to the standards of the Massachusetts Executive Office
of Environmental Affairs, Division of Conservation Services, or Department
of Agricultural Resources in accordance with MGL c. 184, §§ 31
to 33, approved by the Planning Board and Select Board and held by
the Town of Sherborn, the Commonwealth of Massachusetts, or a nonprofit
conservation organization qualified to hold conservation restrictions
under MGL c. 184, §§ 31 to 33. Any proposed open space
that does not qualify for inclusion in a conservation restriction,
watershed, or agricultural preservation restriction or that is rejected
from inclusion in these programs by the Commonwealth of Massachusetts
shall be subject to a restrictive covenant in perpetuity under MGL
c. 184, §§ 26 to 30, which shall be approved by the
Planning Board and Select Board and held by or for the benefit of
the Town of Sherborn.
(b)
The restriction shall specify the prohibited and permitted uses
of the restricted land, which would otherwise constitute impermissible
development or use of the open space, consistent with the allowable
and prohibited uses subsections of this section and any permits. The
restriction may permit, but the Planning Board may not require, public
access or access by residents of the development to the protected
land.
(4)
Timing. Any restriction or other legal document necessary to
permanently conserve open space as required herein shall be recorded
prior to the release of any lots in a subdivision or prior to the
issuance of any building permits.
(5)
Allowable use of the open space. Such land shall be perpetually
kept in an open state, preserved exclusively for the purposes set
forth herein and in the deed and/or in the restriction, and maintained
in a manner which will ensure its suitability for its intended purposes.
Proposed use(s) of the open space consistent with this section shall
be specified in the application.
(a)
The open space shall be used for wildlife habitat and conservation
and/or the following additional purposes or a combination of these
uses to the extent allowed by Massachusetts General Laws, and shall
be served by suitable access for such purposes: historic preservation,
outdoor education, forestry and passive recreation. Agriculture or
horticulture shall be allowed if the land was in such use at the time
of approval of the definitive plan. A portion of the open space may
be used for new agriculture, horticulture or community gardens, provided
that only organic methods are employed.
(b)
The Planning Board may permit a small portion of the open space,
not to exceed 5%, to be paved or built upon (using permeable pavement
and other means of retaining natural hydrology) for purposes accessory
to the dedicated use or uses of such open space, so long as the conservation
values of the open space are not compromised. Examples of such purposes
are parking to facilitate public access for passive recreation, informational
kiosks, pedestrian walks, ADA access features, and bike paths. Construction
of barns or other farm structures will be allowed on 5% of the protected
open space that is in agricultural or horticultural use as defined
by MGL c. 128, § 1A.
(c)
The open space may be used as the land subject to a restriction
for the purpose of an aggregate calculation under Title 5, 310 CMR
15.000 of the State Environmental Code, MGL c. 21A.
(6)
Prohibited use of the open space. The open space within an open space subdivision shall be perpetually kept in an open state, preserved exclusively for the purposes set forth in Subsection
G(5) of this bylaw, and maintained in a manner that will ensure its suitability for its intended purposes. Expressly prohibited uses, if not specifically permitted as an allowable use, include but are not limited to the following:
(a)
Constructing or placing of any temporary or permanent building,
tennis court, landing strip, mobile home, swimming pool, asphalt or
concrete pavement, sign, billboard or other advertising display, antenna,
utility pole, tower, conduit, line or other temporary or permanent
structure or facility on, above, or under the open space that is not
in conformance with an authorized use of the open space (e.g., fencing,
barn or other structure associated with agriculture);
[Amended 4-25-2023 ATM
by Art. 23]
(b)
Mining, excavating, dredging, or removing soil, loam, peat,
rock, gravel or other mineral resource or natural deposit, unless
necessary to install infrastructure that is part of the approved plan;
(c)
Placing, filling, storing, or dumping of soil, refuse, trash,
vehicles or parts thereof, rubbish, debris, junk, waste, or other
substance or material whatsoever or the installation of underground

(e)
Subdivision; neither further division of the protected open
space into lots or the use of the protected open space toward any

[Amended 4-25-2023 ATM
by Art. 23]
(c)
The Town of Sherborn, with the consent of the Select Board,
under management of the Town Forest or Conservation Commission, with
their consent; or
(d)
A homeowners' association (HOA) as defined herein, owned jointly
or in common by the owners of lots or units within the open space
subdivision.
[Amended 4-25-2023 ATM
by Art. 23]
(2)
If ownership option H(1)(d) is selected the following shall
apply:
(a)
The documents organizing the HOA shall be drafted by the applicant
and approved by the Planning Board before final approval of the open
space subdivision development, recorded prior to the issuance of building
permits, comply with all applicable provisions of state law, and pass
with conveyance of the lots or units in perpetuity. Each individual
deed, and the deed, trust, or articles of incorporation, shall include
language designed to effect these provisions.
(b)
Membership must be mandatory for each property owner, who must
be required by recorded covenants and restrictions to pay fees to
the HOA for taxes, insurance, and maintenance of common open space,
private roads, and other common facilities.
(c)
The HOA must be responsible in perpetuity for liability insurance,
property taxes, the maintenance of recreational and other facilities,
preservation of the open space in accordance with this bylaw, private
roads, and any common driveways.
(d)
Property owners must pay their pro rata share of the costs in Subsection
H(2)(c) above, and the assessment levied by the HOA must be able to become a lien upon individual properties within the open space subdivision.
(e)
The HOA must be able to adjust the assessment to meet changed
needs.
(f)
The applicant shall make a conditional grant to the Town of
Sherborn, Sherborn Conservation Commission, binding upon the HOA,
of the fee interest to all open space to be conveyed to the HOA. Such
offer may be accepted by the Conservation Commission, at the discretion
of the Select Board, upon the failure of the HOA to take title to
the open space from the applicant or other current owner, upon dissolution
of the HOA at any future time, or upon failure of the HOA to fulfill
its maintenance obligations hereunder or to pay its real property
taxes on the open space.
(g)
Ownership shall be structured in such a manner that real property
taxing authorities may satisfy property tax claims against the open
space lands by proceeding against individual property owners in the
HOA and the dwelling units they each own.
(h)
Sherborn Town Counsel must find that the HOA documents presented satisfy the conditions in Subsections
H(2)(a) through
(g) above, and such other conditions as the Planning Board shall deem necessary.
(3)
Selection of ownership option H(1)(a), (b) or (d) requires:
(a)
The conveyance of a conservation restriction as outlined herein;
and
(b)
The granting of an access easement over such land sufficient
to ensure access for Sherborn Town officials to ensure its perpetual
integrity and maintenance as agricultural, conservation, or recreation
land. Such easement shall provide that in the event the owner fails
to maintain the open space in reasonable condition, Town officials
may, after notice to the lot owners and any grantee of a restriction,
and after Select Board public hearing, enter upon such land to maintain
it in order to prevent or abate a nuisance.
I. Maintenance:
(1)
Maintenance standards. The Planning Board shall require the
establishment of ongoing maintenance standards as a condition of development
approval to ensure that utilities are properly maintained and the
open space land is not encroached upon, or used for storage or dumping
of refuse, junk, or other offensive or hazardous materials. Such standards
shall be enforceable by the Town against any owner of open space land,
including an HOA.
(2)
Enforcement of maintenance standards.
(a)
If the Select Board finds that the maintenance provisions are
being violated to the extent that the condition of the utilities or
the open land constitutes a public nuisance, it may, upon 30 days'
written notice to the owner/grantee, enter the premises for necessary
maintenance, and the cost of such maintenance by the Town shall be
assessed proportionally against the landowner or, in the case of an
HOA, the owners of properties within the subdivision, and shall, if
unpaid, become a property tax lien on such property or properties.
[Amended 4-25-2023 ATM
by Art. 23]
(b)
Pursuant to MGL c. 40, § 58, Sherborn may file a lien
against the subdivision lot or lots to ensure payment for such maintenance.
Pursuant to MGL c. 40, § 57, Sherborn may also deny any
application for, or revoke or suspend a building permit or any local
license or permit, due to neglect or refusal by any property owner
to pay any maintenance assessments levied.
J. Submission requirements: In order to enable the Planning Board to
determine whether or not a proposed open space subdivision design
(or alternative subdivision development requiring a special permit
that deviates from the requirements for open space design) satisfies
the purposes and standards of this open space subdivision section
of the Zoning Bylaw and the Subdivision Rules and Regulations of the
Planning Board, an applicant must present sufficient information on
the environmental and open space resources for the Board to make such
a determination.
Consistent with MGL Chapter 94G, Section 3(a)(2), all types
of marijuana establishments as defined in MGL Chapter 94G, Section

marijuana product manufacturers, marijuana retailers or any other
types of licensed marijuana-related businesses, shall be prohibited
in the Town of Sherborn. This section shall be effective upon passage
by the voters at a Town election.
[Amended 4-23-2024 ATM
by Art. 14]
A. Purpose and intent.
(1)
Affordable housing produced through this section should comply
with the requirements set forth in MGL c. 40B, §§ 20
to 23, and related regulations, guidelines issued by Massachusetts
Executive Office of Housing and Livable Communities (EOHLC), and other
affordable housing programs developed by the Commonwealth of Massachusetts
and/or the Town of Sherborn. EOHLC each year provides formulations
to define "eligible households," "affordable housing," "subsidized
housing inventory (SHI)" and similar terms used throughout this section.
(2)
The purpose of this affordable housing section is to create
housing opportunities in Sherborn for people of varying ages and income
levels; to increase the supply of affordable housing for eligible
households with low and moderate incomes; to promote a mix and geographic
distribution of affordable housing throughout the Town; to provide
housing options for people who work in Sherborn; and to create housing
units eligible for listing in the subsidized housing inventory.
B. Applicability.
(1)
This section shall apply to the following uses:
(a)
Any development of six or more dwelling units. Developments on properties that are contiguous and under common site control shall be considered a single development for purposes of this §
240-4.9. Common site control may be established by showing that the same or a related person or entity holds title, ground lease, option, or contract for purchase with respect to such properties.
(b)
Any subdivision development approved under §
240-4.5 of this Zoning Bylaw.
(c)
Planned unit development (PUD) approved pursuant to a PUD special permit under §
240-4.6 of this Zoning Bylaw.
(d)
Multidwelling EA projects approved pursuant to a preliminary development plan approved at Town Meeting in conjunction with a rezoning of land to EA, and a special permit under §
240-5.6 of this Zoning Bylaw.
(2)
This section shall not apply to the construction of single-family
dwellings on individual lots if said lots were in existence prior
to the effective date of this section.
C. Mandatory provision of affordable housing units.
(1)
Except as otherwise provided for in Subsection
D(3), in any development subject to this section, 10% of the dwelling units in such development shall be affordable housing units.
(2)
A fractional affordable housing unit of 0.5 or higher shall be rounded up to the next whole number. Fractional housing units of less than 0.5 shall require a cash payment to the Sherborn Affordable Housing Trust as specified in Subsection
D(3). The applicant may choose to have the fractional housing unit of less than 0.5 rounded up to the next whole number, rather than converted to a cash payment.
(3)
Any affordable housing unit shall have a deed rider to regulate
the future resale of the property.
D. Methods of providing affordable housing units. The Planning Board
in consultation with the Sherborn Affordable Housing Board of Trustees,
if in existence, may authorize one or more of the following methods
for providing affordable housing units, alone or in combination.
(1)
On-site units. Construction of affordable housing units within
the development shall be permitted by right. The following conditions
shall apply:
(a)
On-site affordable housing units shall be in accordance with
the requirements of the Local Initiative Program (LIP), a state housing
initiative administered by the EOHLC to encourage communities to produce
affordable housing for low- and moderate-income households.
(b)
On-site affordable housing units shall be as conveniently located
to the development's common amenities as the market rate units.
(2)
Off-site units. Creation of affordable housing units on a lot
or parcel that is not included in the subject development may be approved
by the Planning Board. The following conditions shall apply:
(a)
An off-site affordable housing unit may be constructed by the
applicant or be an existing dwelling unit that is rehabilitated or
repurposed by the applicant.
(b)
Off-site affordable housing units need not be located in the
same zoning district as the development. The required number of off-site
affordable housing units may be created at one or multiple locations,
and may consist of a combination of newly constructed and existing
dwelling units, either rehabilitated or repurposed.
(c)
The location or locations of the off-site affordable housing
units shall be subject to approval by the Planning Board. Off-site
affordable housing units may be constructed as (if new) or converted
to (if existing) a duplex or multifamily building offering two or
more dwelling units. If in an area of single-family homes, the final
result must be that the premises (including primary building, accessory
structures, driveway, etc.) have the appearance of a single-family
home as determined by the Planning Board. Exterior renovations/improvements
shall reflect the character of the surrounding neighborhood.
(d)
The applicant shall provide a demonstration of site control,
documenting that the applicant or a related entity holds title, ground
lease, option, or contract for purchase.
(e)
The applicant shall demonstrate that the land is developable
and suitable for the number of affordable housing units required in
conformance with this Zoning Bylaw and any other relevant state and
local regulations governing the property.
(f)
The applicant shall provide a demonstration of the necessary
financing to complete the off-site development or rehabilitation.
(g)
The applicant shall provide an architect's conceptual site plan with unit designs and architectural elevations, and a demonstration that the site plan can meet the site plan review standards set forth in §
240-5.3 of this Zoning Bylaw.
(h)
The Planning Board may require that the applicant submit appraisals
of the off-site property in question, as well as other data relevant
to the determination of equivalent value.
(i)
Off-site affordable housing units shall not be approved by the
Planning Board unless it can be documented that the units will be
approved by EOHLC to be added to the Town's Subsidized Housing Inventory
(SHI).
(j)
The EOHLC LIP (Local Initiative Program) Design and Construction
Standards as may be amended shall apply.
(3)
Payment in lieu of affordable housing units.
(a)
Such payments shall be made to the Sherborn Affordable Housing
Trust if in existence.
(b)
The payment shall be according to the following formula:
N x (M - A) = Required payment in lieu
|
Where:
|
N
|
=
|
the number of required affordable housing units calculated pursuant to § 240-4.9C
|
M
|
=
|
the median sales price for market rate housing units during
the 24 months prior to the submission date of the project application.
The value of M is determined by the Sherborn Board of Assessors
|
A
|
=
|
the EOHLC-determined selling price of an affordable unit for
the housing type in the proposed development
|
Example: Project size is 15 housing units. Based on 10% affordable
units, 1.5 affordable housing units are required, and must be rounded
up to 2. Where M=$850,000 and A = $250,000, then 2 x ($600,000) =
$1,200,000 payment in lieu of providing affordable housing units.
The applicant may decide to build 2 affordable housing units instead
of making a payment or build 1 affordable housing unit and make a
payment of $600,000.
|
E. Location and comparability of affordable housing units.
(1)
The permit application for the proposed development shall include
a plan showing the proposed locations of the affordable housing units.
(2)
Newly constructed on- and off-site affordable housing units
shall:
(a)
Comply at a minimum with the EOHLC LIP Design and Construction
Guidance as it may be amended, including the requirement that affordable
housing units, except for size, shall be indistinguishable from market-rate
units as viewed from the exterior.
(b)
Be equivalent to the market-rate units in terms of design, quality
of construction and workmanship, mechanical, plumbing, heating and
cooling systems, roofing, insulation, windows and energy efficiency.
(c)
Include a garage(s) and/or parking space if the market-rate
units include a garage(s) and/or parking space.
(d)
Contain good quality and highly durable interior finishes, flooring,
lighting and plumbing fixtures, and appliances that are consistent
with contemporary standards for new housing and installed with equivalent
workmanship to the market rate units.
(e)
Provide product and system warrantees equivalent to those supplied
for market rate units.
(3)
Off-site rehabilitated units for affordable housing shall comply
at a minimum with the following criteria:
(a)
Exterior renovations/improvements shall reflect the character
of the surrounding neighborhood.
(b)
The EOHLC's LIP Design and Construction Standards as may be
amended shall apply.
(4)
Newly constructed affordable housing units shall contain at
least the minimum amount of interior living space, excluding basement
space, as specified in the EOHLC LIP Design and Construction Guidance.
(5)
In the case of existing off-site dwelling units purchased and
resold or rented as affordable housing units with an appropriate deed
restriction, the Planning Board may make reasonable exceptions for
the size and number of bedrooms.
(6)
The owners and tenants of market-rate and on-site affordable
housing units shall have the same rights and privileges to use any
common amenities within the development.
(7)
The Building Commissioner may inspect the premises to ensure
that the developer has complied with these requirements and if necessary,
require reasonable changes to achieve compliance.
F. Affordable purchase and rental prices.
(1)
The initial affordable purchase price shall comply with the
EOHLC LIP Guidelines in effect when the regulatory agreement is filed
with EOHLC. The regulatory agreement is a comprehensive agreement
among the Town, developer and EOHLC which defines the responsibility
for monitoring and enforcing the affordable unit in perpetuity. It
determines the calculations used to determine an affordable purchase
price that is consistent with the terms, rates, fees, down payments,
and other requirements of first-time homebuyer mortgage products available
from lending institutions licensed by the Commonwealth of Massachusetts
in accordance with the requirements of EOHLC.
(2)
In a rental project, the initial affordable rent shall comply
with applicable EOHLC requirements and LIP Guidelines.
G. Applicant responsibilities.
(1)
Marketing plan for affordable housing units. The applicant shall
select qualified purchasers and renters via lottery under an affirmative
fair housing marketing plan prepared and submitted by the Applicant
and approved by the Planning Board in consultation with the Sherborn
Affordable Housing Trust. The marketing plan shall comply with LIP
Guidelines in effect on the date of filing the regulatory agreement
with EOHLC.
(2)
Regulatory agreement. For both ownership and rental projects,
the applicant shall prepare the regulatory agreement in consultation
with and for approval by the Town of Sherborn and EOHLC. Said regulatory
agreement will be executed by EOHLC, the Town of Sherborn, and the
applicant. The applicant shall record the regulatory agreement with
the Middlesex County Registry of Deeds or Registry District of the
Land Court.
(3)
Deed restriction. The applicant shall prepare a deed rider for
each affordable housing unit that is consistent with that used in
the LIP and the regulatory agreement to be recorded with the Middlesex
County Registry of Deeds or Registry District of the Land Court.
H. Timing of construction of affordable housing units.
(1)
On-site affordable housing units shall be constructed in accordance
with table below. Proportionality shall be determined by the number
of building permits issued for affordable and market-rate units. In
accordance with the table, affordable housing units shall not be the
last units to be built in any development that is subject to this
section.

In the case of payments in lieu of affordable housing units,
the following methods of payment may be used at the option of the
applicant:
(a)
The total amount due shall be paid upon the release of any lots
or, in the case of a development other than a subdivision, upon the
issuance of the first building permit; or
(b)
The total amount due shall be divided by the total number of
market rate units in the development. The resulting quotient shall
be payable at, or prior to, the closing of each market rate unit;
or
(c)
A combination of the above methods if approved by the Planning
Board.
I. Preservation of affordability.
(1)
Homeownership and rental affordable housing units provided under
this section shall be subject to the requirements of guidelines issued
by EOHLC and an EOHLC-approved deed rider that complies with LIP requirements
as they may be amended for inclusion in the Chapter 40B Subsidized
Housing Inventory and is enforceable under MGL c. 184, § 26,
or MGL c. 184, §§ 31 to 32. Affordable housing units
required by and provided under the provisions of this section shall
remain affordable to the designated income group in perpetuity, or
for as long as legally permissible.
(2)
No building permit for any unit in a development subject to
this section shall be issued until the Town has approved the regulatory
agreement and the applicant has submitted it to EOHLC. Further, the
building permit representing 51% of the development shall not be issued
until the regulatory agreement has been approved by EOHLC and recorded
with the Middlesex County Registry of Deeds or Registry District of
the Land Court.
(3)
For homeownership units, issuance of the certificate of occupancy
for any affordable housing unit is contingent on an EOHLC-approved
deed rider signed by the qualified purchaser and recorded with the
Middlesex County Registry of Deeds or Registry District of the Land
Court.
(4)
Subsequent resale of an affordable housing unit shall be made
to a qualified affordable housing purchaser in accordance with the
deed restriction.
(5)
The purchaser of an affordable housing unit shall execute a
deed rider in a form provided by the EOHLC, granting, among other
things, the Town of Sherborn the right of first refusal to purchase
the property in the event that a subsequent qualified purchaser cannot
be found.
