SECTION APPLIES TO ACCESSORY DWELLING UNITS WHEN A LOT
HAVING NO MORE THAN ONE SINGLE-FAMILY DWELLING UNIT IS
PERMITTED ONE OR MORE ADUS PER THE UNDERLYING ZONING
DISTRICT.
2.
An ADU is not permitted on a lot with a single-family attached dwelling unit,
a duplex, triplex, or multifamily dwelling units, unless otherwise permitted by

PATIO, CARPORT, BREEZEWAY, OR SIMILAR.

3.
An ADUS may be either attached to or detached from the primary dwelling
unit, ARE subject to the following design guidelines:

17
Ordinance G

a.
An attached ADU shall be integrated into the design of the primary
dwelling unit so that it appears to be part of one single family home,
rather than a duplex. This guideline does not prohibit the provision of
separate entry features. (P)
b.
A detached ADU, when visible from adjacent streets, shall be
constructed with similar and/or complementary materials, design, and
color(s) as the primary dwelling unit, SHOULD HAVE A
RESIDENTIAL APPEARANCE IN NATURE AND DESIGN, or as may
be approved by Historic Preservation for HP zoned or designated
properties. (P)

Rationale: ADUs are intended be subordinate to the primary single-family
home and should visually appear as such. An ADU which looks like a
second duplex unit, or a second detached primary dwelling unit, does not
meet this intent. MATERIALS MORE COMMONLY ASSOCIATED WITH
COMMERCIAL STRUCTURES SHOULD BE AVOIDED. HOWEVER,
THESE DESIGN GUIDELINES DO NOT REQUIRE THAT AN ADU
MATCHES THE EXTERIOR DESIGN, ROOF PITCH, OR FINISHING
MATERIALS OF THE PRIMARY DWELLING UNIT.

WHEN NOT LOCATED WITHIN ANY REQUIRED YARD:
THE SAME HEIGHT AS PERMITTED FOR THE PRIMARY
DWELLING UNIT.

5.
A detached ADU not located within the required rear yard and compliant
with the same setbacks required for the primary dwelling unit is subject to
the same height regulations as the primary dwelling unit.

SETBACK, Aa detached ADU may not be located between the primary
dwelling unit and the front property line unless use permit approval is
obtained per Section 307.
