How long does an ADU permit take in Fresno?

Typically about 6 weeks from complete application to approval. Five free city pre-approved ADU plans (340 / 499 / 625 / 625-over-garage / 1,015 sq ft) with three elevation options each (Craftsman, Contemporary, Gable). Zone Clearance was eliminated in 2024 for pre-approved plans — applications go directly to Building Permit review. Fire sprinklers required only if the primary residence already has them or site has deficient fire access. Title 24 solar PV required; existing-system credit allowed. NOTE: line-item permit fees triangulated from Fresno County (used as proxy for City of Fresno cost-estimator XLSX) — verify with city before submitting application.

How much does an ADU permit cost in Fresno?

All-in permit-related costs typically run $2,500–$4,000 (Andalusia Drafting 2026; Dynamic Quality Builders 2026). This includes building permit fees, plan check, and professional soft costs. Impact fees may apply for ADUs over 750 sq ft.

Do I need to replace parking when building an ADU in Fresno?

No — California state law eliminates parking-replacement requirements for ADUs within half a mile of public transit, in historic districts, in existing structures (garage conversions), or where on-street parking permits aren't required. Most Fresno ADUs qualify for at least one of these exemptions.
