CA SB765

Removes the existing 4-foot maximum setback requirement for new accessory dwelling units, allowing local agencies to establish their own rear and side yard setback requirements.

Permits accessory dwelling unit applicants to request alternative setback requirements from local agencies if the agency's setbacks make construction infeasible due to site topography.

Caps local setback requirements at levels in effect as of January 1, 2020, or 4 feet if the jurisdiction had no accessory dwelling unit ordinance by that date.

Deletes language that previously mandated 4-foot setbacks for certain new construction accessory dwelling units in multiple sections of the Planning and Zoning Law.

Contains two versions of amendments effective on different dates: one until January 1, 2025, and another operative starting January 1, 2025, with the second version adding owner-occupancy provisions.
