Fresno ADU rules at a glance
Fresno follows local ordinances layered on top of California state ADU law. Typical restrictions cover maximum size (often 800–1,200 sqft), height (16–25 feet), side setbacks (4 feet minimum in most jurisdictions), parking (often waived near transit), and owner-occupancy. Buildability™ reads Fresno's specific code against your exact lot.
Why this matters
A compliant ADU on a Fresno lot can add $150K–$500K in value depending on size and neighborhood. Roughly one in four lots has a dealbreaker — easement, overlay, setback encroachment — that isn't visible from the street. Check before you spend.
