Property Eligibility
Is My Palmdale, CA Property Eligible for an ADU?

Single-Family Home
Permitted on single-family lots in Palmdale under California state law. No owner-occupancy requirement in Palmdale — you can rent both units as investment properties. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 25% of Palmdale homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
