The purpose of establishing architectural standards is to set
minimum standards for the appearance and quality of buildings and
corresponding site elements that are recognized as enhancing property
values and are in the interest of the general welfare of the city.
Given that the City of Celina is an area designated with historical,
cultural, and architectural importance and significance, the following
provisions apply. These standards are not intended to prohibit architectural
innovation, nor are they intended to mandate specific architectural
styles and concepts. Rather, they are intended to provide for developments
of enduring quality that provide visual character and interest. The
development community is encouraged to seek out new and innovative
construction techniques and materials to implement the standards contained
herein that will result in a significant contribution to the visual
character of the area and the city as a whole. Any new or innovative
material shall be considered on a case-by-case basis by the director
and must be equal to or exceed the current standards in terms of quality
and longevity.
(Ordinance 2019-42 adopted 10/8/19)

When an existing building, constructed prior to the adoption of this
section, is proposed for an addition or expansion that will increase
the square footage of the existing building by less than fifty percent
(50%), either by a single expansion or by the cumulative effect of
a series of expansions, similar or like exterior materials may be
used on new facades that match the existing building and architectural
theme to the extent possible.
(d)
Any addition that is fifty percent (50%) or greater of the originally
approved floor area shall be subject to and shall comply with the
regulations herein, potentially resulting in the reconstruction of

so that the total percentage of any given facade remains as shown
above.
|
(5)
Placement of exterior materials.
Notwithstanding the
minimum and maximum percentages of building materials allowed on residential
homes (shown above), any break from one material to another shall
follow the natural lines and design features of the architectural
plan. A change from one material to another cannot be arbitrarily
assigned without consideration of the specific facade for which it
is designed. The director of development services shall have final
approval of any residential elevation submitted for construction.
(6)
Alternate stucco architecture.
If a home is designed
with a specific architectural style that warrants the use of stucco
as the primary exterior material, including but not limited to Mediterranean,
Spanish, Southwest, or Modern, then the use of stucco as the primary
or exclusive material may be approved by the director in lieu of other
exterior material standards. All elements of the architectural style
must be incorporated, including but not limited to clay roof tiles,
typical of the style. Residences with primarily stucco finishes shall
be accented with heavy wood beams, stonework, or other features to
enhance the style. Elevations with no discernable style that simply
disregard the required masonry requirement will not be considered.
Only three-step stucco (or its equivalent) is allowed.
(7)
Elevation repetition.
Any house elevation shall not
be repeated on the lot most directly across the street, nor shall
it be repeated on two (2) lots in either direction on the same side
of the street. A wide variety of elevations is desired as it strengthens
the character of the subdivision and reduces monotony of design. When
stucco homes are the predominant exterior material used on a particular
street, variations of color and design are required to minimize visual
monotony.
(8)
Elevation masonry mix and pattern.
Front elevations
shall use more than one type of masonry product in a variety of patterns
to vary the architectural appeal of the streetscape. Regardless of
the minimum category A masonry requirements, every front facade shall
be a mixture of materials and colors.
(9)
Front facades and front-facing garage placement - one-story homes.
The face of garage doors shall not extend beyond the front facade
of any residential structure unless one or both of the following conditions
apply; and in that case, the face of the garage door may extend up
to a maximum of eight (8) feet beyond the front facade:
(10)
Front facades and front-facing garage placement - two story homes.
The face of garage doors may extend beyond the front facade
of any residential structure up to a maximum of eight (8) feet beyond
the front facade. Any additional garages to be provided must be placed
with side (J-swing) or rear access.
(11)
Front facades and J-swing garage placement.
When the
doors of garages are designed to be perpendicular to the street access
(i.e. J-swing garages), the garage may extend into the front setback
of the residential structure, as per the director.
(12)
Front entry doors.
Front entry doors shall consist of
a hardwood, treated engineered wood, or other highly durable products,
including products that have a wood appearance and are approved by
the director.
(13)
Garage doors.
Front entry doors shall consist of lightweight
but durable materials, such as painted metal, and include materials
that have a wood appearance and are approved by the director. Garage
doors windows are permitted.

standards as listed in the adopted International Building Code, which
includes the use of solid solar shingles and panels.
(16)
Screening of utility units.
HVAC units shall be screened
from view from streets with shrubs or a stained wood fence.
(17)
Mailboxes on individual lots.
The subdivision will determine
whether individual mailboxes shall be brick or stone to match the
residence or decorative metal containers on posts. Where practical,
the mailboxes should be paired for ease of delivery.
(18)
Mailboxes that are clustered.
When mailboxes are clustered
in single-family or two-family residential districts, the exterior
of the clustered mailboxes shall be decorative metal on a matching
support poles and shall be maintained by the homeowners association
(HOA).

(a)
Design standards for industrial structures.
The following
design standards apply to structures constructed in an industrial
zoning district and proposing an industrial and/or manufacturing use,
per the use chart of the zoning ordinance:
(1)
The main entry or office area of the building shall be articulated
both horizontally and vertically by at least five (5) feet or ten
percent (10%) of the adjacent wall height, whichever is greater. Building
corners shall also be articulated, as approved by the director.
(2)
Primary exterior facades, which are clearly visible from a public
street, shall be constructed with a minimum ten percent (10%) category
A materials and up to ninety percent (90%) category B materials, exclusive
of windows and doors. Category C materials may be used for accents.
The category A materials noted above shall be applied to corners,
entries, and other areas in order to mitigate monotony and increase
the aesthetic value. A minimum of two (2) different materials shall
be used.
(3)
Secondary exterior facades NOT facing a public street may be constructed
with up to 100% category B materials.

(Ordinance 2019-42 adopted 10/8/19)
(a)
Gas pumps and fueling stations.
(1)
Materials for the main building shall follow the regulations for non-residential structures (section 14.04.109, general design standards for non-residential structures).
(2)
Canopies shall not exceed twenty (20) feet in total height, measured
from the pavement to the top of the canopy.
(3)
The roofs of convenience store buildings and fueling station canopies
shall be pitched, include a parapet to shield roof-mounted equipment,
or otherwise distinguished, subject to approval by the director.
(4)
Canopies and their supporting structures should be architecturally
integrated with the primary building and all other accessory structures
on the site by using the same or complementary materials, design motif,
and colors.
(5)
Canopy support columns shall be fully encased with type A masonry
products and shall not include any non-structural additions to the
columns.
(6)
Canopy band faces shall be a color consistent with the main structure
or an accent color. The canopy band face shall be flat with no projections,
shall not be of plastic materials, shall be generally a metal or masonry
based material, not be greater than four (4) feet in height, and may
not be backlit or used as signage; except as follows:
(A)
The canopy band face may utilize one (1) small button logo on each
face that can be internally illuminated, as long as each button logo
does not exceed fifteen (15) square feet for bands three (3) feet
in height and twenty (20) square feet for bands four (4) feet in height,
is generally as tall as it is wide, and does not protrude more than
eighteen (18) inches from the canopy in any direction.
(B)
The canopy band face may utilize an external LED halo type light,
if properly shielded/recessed and oriented downward so that only the
“wash” is visible.
(C)
The canopy band face may utilize internally illuminated rings, as
long as the source is LED, it is flush with the band face and only
protrudes nominally (up to a maximum of six (6) inches), and the size
of the ring does not exceed more than twenty-five percent (25%) for
single rings and fifty (50%) for multiple rings of the thickness of
the canopy band face.
(7)
Lighting fixtures (LED only) or sources of light that are a part
of the underside of the canopy should be recessed into the underside
of the canopy.
(8)
The materials and color used on the underside of the canopy should
not be highly reflective, with the intent of minimizing the amount
and intensity of light, which reaches beyond the site boundaries.
(9)
Materials and colors used on both structural and architectural surfaces
shall be subdued, earth-tone colors, with the intent of promoting
a harmonious appearance of the structures and the natural surroundings,
as well as with appearance themes or guidelines of surrounding development.
Brick, stone and other high-quality masonry type elements are required
as a major component of the exterior of all structures.
(10)
Bright accent colors, intended to express corporate or business logos,
may be used only on a limited basis. These accent color areas should
not be internally illuminated, except as allowed by the city’s
sign regulations.
(11)
Exhaust valves for underground fuel storage tanks shall be designed
to be located against a building, dumpster screening wall, or other
structure to mitigate their visual impact and should be an earth-tone
color. If impractical, the exhaust valves may be located in an interior
landscape area, if properly screened, but should not be located in
the exterior landscape buffer adjacent to the public right-of-way.
