Fresno ADU design & construction
Fresno directs both custom and preapproved ADUs straight to a building-permit application: its ADU page says a separate Zone Clearance is no longer required. Its catalog includes an ADU above a garage as well as ground-level designs.

What matters for an ADU in Fresno
Permitting authority: City of Fresno — ADU Program
Official local guidanceLocal rules and design checks
| Topic | Local guidance |
|---|---|
| Application path | Apply directly for the building permit rather than obtaining a separate ADU Zone Clearance. |
| Plan selection | Five City plan types have three elevation options each. |
| Solar package | The program includes solar drawings; coordinate the selected design and site-specific requirements in the permit package. |
Selected local requirements, not a complete zoning determination. Confirm the current rules for your address with the responsible agency.
Fees and budget checks
Use the ADU program’s cost-estimator link and request a current project estimate. Older quick-start brochures contain historical figures and should not be treated as today’s complete permit price.
