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

Single-Family Home
Permitted on single-family lots in Fresno under California state law. No owner-occupancy requirement in Fresno — 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 20% of Fresno 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.
Historic Districts
Yes - in historic districts and areas with adopted design guidelines (not citywide)
