§9056.4 PARKING — Ukiah Zoning Code

Parking requirements for the ADU shall be one off-street space (independently accessible or tandem) in addition to the accessible parking spaces required for the existing single-family or multifamily residence. If the primary residence was legally constructed at a time when on-site parking was not required, then only the parking space(s) for the ADU shall be required.
Off-street parking shall be permitted in setback areas in compliance with the definition of “off-street parking” found in section 9278B of this code or through tandem parking.
Parking standards will not be imposed for an ADU in any of the following instances:
The ADU is located within one-half (1/2) mile of a public transit stop;
The ADU is located within an architecturally and historically significant district;
The ADU is part of the existing primary residence or an existing accessory structure;
When on-street parking permits are required but not offered to the occupant of the ADU;
When there is a car share vehicle located within one block of the ADU;
When an application for an ADU is submitted with an application to create a new single- family or multifamily dwelling on the same lot.
If a garage (attached or detached), carport, or uncovered or covered parking structure is demolished in conjunction with the construction of an ADU or converted to an ADU, the City shall not require that those off-street parking spaces be replaced. 5. No parking shall be required for ADUs created pursuant to Government Code § 66323, including:
Converted ADUs in existing single-family homes or accessory structures;
New detached ADUs (≤ 800 square feet);
ADUs converted from non-livable space in multifamily buildings (up to 25% of units); 4. Detached ADUs on lots with multifamily structures. (Ord. 1244, §5, adopted 2024; Ord. 1258, §2, adopted 2025) §9056.5 LEGAL NONCONFORMING ACCESSORY STRUCTURES

ADUs converted from residential accessory structures determined to be legal nonconforming shall be subject to the following requirements:

A. A legal nonconforming residential accessory structure that is converted to an ADU, or reconstructed as an ADU to the same footprint and dimensions as the original structure, shall not be subject to
setback requirements.
B. A legal nonconforming residential accessory structure that is converted to an ADU may be expanded up to one thousand two hundred (1,200) square feet if the expansion will comply with the height limit
and setbacks for new detached ADUs.
C. Expansion of floor area within a nonconforming setback is limited to one hundred fifty (150) square feet, if necessary, to accommodate associated utilities, ingress and egress.
D. Delay of Enforcement of Building Standards.
1. The owner of an Accessory Dwelling Unit that was built before January 1, 2020, may submit an application to the Building Official requesting correction of any violation of building standards. For purposes
of this Section, “building standards” refers to those standards enforced by permitting agencies under the authority of Section 17960 of the California Health and Safety Code.
2. The Building Official shall grant the application if determined that enforcement of the building standard is not necessary to protect health and safety. In making this determination, the Building Official
shall consult with the Fire Official.
3. Any notice to correct a violation of a building standard that is issued to the owner of an Accessory Dwelling Unit built before January 1, 2020, shall include a statement that the owner has a right to request
a delay in enforcement of the building standard for an Accessory Dwelling Unit pursuant to this Section.
4. The City shall not impose impact fees or connection or capacity charges for ADUs legalized under this Section.
(Ord. 1244, §5, adopted 2024; Ord. 1258, §2, adopted 2025)
§9056.6 HEIGHT

§9056.7 DETERMINATION OF APPROPRIATENESS
Whenever an ADU is proposed that would involve uses or features that are not explicitly addressed by the design and development standards set forth in this code or State law, the Community Development
Director shall determine whether the proposal is appropriate and whether it should be reviewed on a ministerial or discretionary basis. In making this determination, the Community Development Director
shall find as follows:
A. The proposed ADU would not be incompatible with other existing or allowed uses in the zoning district or property for which it is proposed; and
B. The proposed ADU would not be detrimental to the continuing development of the area in which it would be located; and
C. The proposed ADU would be in harmony and consistent with the purpose of the zoning district; and
D. The proposed ADU can meet all safety requirements as determined by the City of Ukiah Building Inspection and Fire Prevention Division; and
E. In the case of determining that an ADU is allowed or permitted, the Community Development Director shall find that the proposed use is similar in nature and intensity to its contextual development and
the ADU allowances listed in this code or State law. (Ord. 1244, §5, adopted 2024)
