Development
Standards. Except as modified by this section or as otherwise provided
by state law, an ADU shall conform to the development standards applicable
to the lot on which it is located as set forth in this title and/or
in an applicable specific plan or planned unit development ordinance
or resolution. Pursuant to Sections 9.12.040.030 and 9.18.110.040,
lots located in multiple-family residential and mixed-use zoning districts
that are improved with single-family residential uses are subject
to certain single-family residential development standards. Notwithstanding
the foregoing, when the application of a development standard related
to floor area ratio, lot coverage, open-space, or minimum lot size
would prohibit the construction of an attached or detached ADU of
at least 800 square feet, such standard shall be waived to the extent
necessary to allow construction of an ADU of up to 800 square feet.
