(a) Purpose:
The multi-family zoning standards provide for a mix of multi-family
types and style of development intended to reinforce the neighborhood
and small town character desired by Alamo Heights residents. The standards
permit multi-family buildings of two (2) to four (4) stories in height,
depending on location, and require mixed uses along Broadway south
of Albany Street in order to encourage pedestrian traffic and extended
visits that are essential to a vibrant mix of retail, service and
hospitality businesses.
(b) Variety:
The standards are intended to allow a variety of desirable multi-family
housing types as illustrated in the comprehensive plan adopted on
May 26, 2009, including: duplex/triplex/quadplex and larger apartment
buildings; attached townhouses; bungalow courts with attached or detached
dwellings located around a central garden; courtyard housing with
attached dwellings around a central linear walk; and garden walk or
lane housing with detached or townhouse dwellings facing a well-landscaped
central walk or winding car lane.
(c) Character:
The multi-family zoning standards envision multi-family dwellings
that are compatible with and reinforce the best design characteristics
of Alamo Heights. Such characteristics include front doors and main
entries that face the street (or common landscaped areas); front facades
that mimic surrounding properties in scale, massing and articulation;
building setbacks that respect traditional neighborhood or downtown
street patterns; and off-street parking that is located to the rear
(or underground), in open spaces or carports or garages, and hidden
from (or not prominent in) street views.
(d) Public
realm:
The multi-family zoning standards are intended
to promote a walkable, safe and pedestrian-friendly community. The
standards require ample sidewalks, generous planting strips (or tree
wells) located between the curb and the sidewalk, and regularly spaced,
native canopy trees in the planting strips or tree grates. The standards
are designed to promote water conservation and mitigate the effects
of noise, dust, artificial lighting intrusions and "heat islands"
in developed areas.
(Ordinance 2037 adopted 11/9/2015)
(a) For any multi-family project located on Broadway, south of Albany Street, the 1st floor adjacent to the public rights-of-way shall only be utilized for "Commercial and Retail" land uses which are permitted in Business District One (B-1) and Office District (O-1), as permitted in article II, section
3-8.
(b) One-family
dwellings, attached and detached, are prohibited on properties that
have their front lot line along Broadway or Austin Hwy.
(Ordinance 2037 adopted 11/9/2015)
The minimum lot area in the MF-D shall be in accordance with
the following, and no lot existing at the time of passage of this

seven hundred fifty (3,750) square feet for each unit. Each of the
remaining (interior) units shall require a lot area equal to at least
two thousand two hundred fifty (2,250) square feet per unit. This
does not avoid the necessity to meet other requirements of the Zoning
Code and other codes and ordinances).

family dwelling up to thirty-five (35) feet:
Nine thousand
(9,000) square feet for first four (4) units plus one thousand five

dwelling attached:
Twenty-five (25) feet (The required
lot width of twenty-five (25) feet is for a one-family dwelling attached
unit facing the street from which the address is derived. Units to
the rear of the initial unit do not add to the required front yard
width. This does not avoid the necessity to meet other requirements
of the Zoning Code and other codes and ordinances).
(4) Multiple
family dwelling:
Seventy-five (75) feet.
(Ordinance 2037 adopted 11/9/2015)

measured from the lower side of the fence, wall or other barrier,
or in excess of six (6) feet in height within the remaining portion
of a front yard measured from the lower side of such fence, wall or
other barrier. When the grade of the land adjacent to the location
of a fence, wall or other barrier has been altered from its natural
condition, the director shall determine the permissible height of
a fence, wall or other barrier from the director's projection of the
natural grade of the land.
(5) Main
structure articulation: The maximum exterior front wall plane width
without a minimum of a two-foot-deep by ten-foot-wide for the full
height of the structure, above the first floor, offset is every thirty
(30) feet. Modifications to the articulation standards may be modified

approval.
