The city council finds that the city is experiencing a severe
shortage of housing, especially affordable housing, and that facilitating
the development of accessory dwelling units will increase the housing
options for family members, seniors, low-wage workers, persons with
disabilities, students and others in the community. Because accessory
dwelling units are an essential component of the city's housing supply,
an accessory dwelling unit that conforms to all applicable requirements
shall not be considered to exceed the allowable density for the lot
upon which it is located, and is deemed to be a residential use that
is consistent with the existing general plan and zoning designations
for the lot.
(Ord. 3209-23 § 1)
The following requirements apply to all accessory dwelling units.
(a) Building Requirements. All otherwise applicable requirements of Title
16 (Buildings and Construction) shall be satisfied subject to the exemptions contained in Chapter

access from the single-family dwelling. The entrance to the unit and
the entrance to the single-family dwelling shall not be on the same
wall plane facing the public street.

dwelling unit, and the applicant shall not be required to replace

subdivisions of real property otherwise prohibited by this code or
state law.

1, 2020, shall not be used as a short-term rental.

affected by the construction of the accessory dwelling unit.

all other applicable legal requirements that are not inconsistent
