Automobile parking is not required for ADUs created within an existing or proposed main home or an existing accessory structure. ADU parking may be required if the ADU exceeds the existing square footage of an existing main home (primary residence) or accessory structure, as well as for a newly constructed detached ADU. Other parking waivers in LAMC Section 12.22 A.33(c)(12)(i) may also apply.

As of June 9, 2025, LADBS will start accepting applications using the process shown in the Implementation Guidelines.

Generally, an appeal to the BBSC is scheduled for a hearing date within thirty days of receipt of the appeal to the BBSC. This time period will be extended in cases that require additional documentation and/or research. In the case of import/export applications, the scheduled hearing date is contingent upon receipt of the appropriate environmental clearance from the Department of City Planning (i.e. Categorical Exemption, Mitigated Negative Declaration, or Environmental Impact Report) AND responses from the Department of Transportation and the Department of Public Works.
