§9225.3 BUILDING TYPES

Ukiah Zoning Code · 2026-07 edition · updated 2026-07-07 · Ukiah

Table 5 illustrates the required location of each building type depicted relative to the frontage lines and lot lines of a parcel and identifies uses often associated with each building type.

Table 5: Building Types

Building Types ZONE
a.
Side Yard. A building that occupies one side of
the lot with the setback to the other side. The
visual opening of the side yard on the street
frontage causes this building type to appear
freestanding. A shallow frontage setback defines
a more urban condition. If the adjacent building
is similar with a blank party wall, the yard can be
quite private. This type permits systematic
climatic orientation in response to the sun or the
breeze. Examples of uses often associated with
this building type include duplex, multifamily,
live/work, and mixed-use.
GU
UC
b.
Rear Yard. A building that occupies the full
frontage, leaving the rear of the lot as the sole
yard. This is a very urban type as the continuous
facade steadily defines the public thoroughfare.
The rear elevations may be articulated for
functional purposes. In its residential form, this
type is the rowhouse. For its commercial form,
the rear yard can accommodate substantial

parking. Examples of uses often associated with
this building type include duplex, multifamily,
live/work, and mixed-use (retail-office, service-
office, retail/office-residential).
c.
Courtyard. A building that occupies the
boundaries of the lot while internally defining
one or more private patios. The building may be
open only in the center (as shown) or may be
open to one side in a “C” configuration (Figure
3C). This is the most urban of types as it is able
to shield the private realm from all sides while
strongly defining the public thoroughfare.
Examples of uses often associated with this
building type include apartments,
condominiums,lodging,and mixed-use.
GU
UC
DC
d.
Edge Yard. A building that occupies the center of
its lot with setbacks on all sides. This is the least
urban building type as the front yard sets it back
from the frontage, while the side yards weaken
the spatial definition of the public thoroughfare
space. The front yard is intended to be visually
continuous with the yards of adjacent buildings.
The rear yard can be secured for privacy by
fences and a well-placed accessory building.
Edge yard buildings are prohibited in the GU,
DC and DC zoning districts.
