Summary
Palmdale requires the property owner to live on-site whenever a junior accessory dwelling unit shares a bathroom with the main house, occupying either the primary residence or the JADU itself as their principal residence, with narrow exceptions for public agencies and land trusts.
Owner Occupancy. Pursuant to Government Code Section 66333(b), owner occupancy shall be required if the junior accessory dwelling unit shares sanitization facilities with the existing primary dwelling. In such cases, the owner shall reside in either the single-family residence or the junior accessory dwelling unit as the owner's principal residence. Owner-occupancy is not required if the owner is a governmental agency, land trust, or "housing organization" as that term is defined in Government Code Section 65589.5(k)(2), as that section may be amended from time to time.
Full Breakdown
" Where that condition is met, the owner must reside in either the single-family residence or the JADU as their principal residence, meaning the requirement can be satisfied from either side of the shared-bathroom arrangement. 5(k)(2). 010(E)(4)(d), which requires JADU permits to include owner-occupancy compliance as one of the binding restrictions filed with the County Recorder before the City issues the permit. The JADU-specific standards in subsection (G) also require an efficiency kitchen with a food-preparation counter and storage cabinets sized to the unit under (G)(2), exempt the JADU from any parking requirement under (G)(3), and require exterior access with side and rear setbacks sufficient for fire safety under (G)(4).
Because owner-occupancy is conditioned on shared sanitization facilities rather than imposed on every JADU, a JADU built with its own separate bathroom does not trigger this requirement at all.
Violations & Fines
Failure to maintain owner-occupancy where required breaches the recorded covenant filed under § 17.91.010(E)(4), which the code makes binding on successors in ownership; noncompliance exposes the property owner to legal action under § 17.91.010(E)(4)(c) for violating the standards governing junior accessory dwelling units.
