Preapproved ADU's

Are you looking for a faster, lower-cost way to build an accessory dwelling unit (ADU)?

Standardized construction plans that are preapproved by the City enable the fastest, lowest-cost permit process.

You are still required to submit a site-specific plan that shows the location of the preapproved ADU. A Contractor or builder usually handles the permit process.

Same-day permit issuance! 

If the site-specific plan and related documents are accurate and complete, permits may be issued on the same day of the scheduled plan review meeting. Exception: Projects with a deferred site-specific structural submittal may take longer to review. To use preapproved plans, the project must meet all of the following criteria:

• Lot must be zoned residential and have an existing single-family home or duplex.
• Lot must NOT be located in a geohazard zone, landslide zone, flood zone or Wildland-Urban Interface (WUI) area; see the ADU Universal Checklist to determine these designations. 
• The project must NOT require a Fire Variance.
• The project address must NOT have an open Code Enforcement violation.

HOMEOWNERS - HOW TO GET A PREAPPROVED ADU

I want to use preapproved ADU plans. How do I proceed?

Explore the Preapproved ADU Vendor List. You may wish to contact several vendors and learn about their options, pricing, and installation approach. Be sure to confirm the vendor's role in submitting the plans and securing the building permit. It is highly advised that you have the vendor or contractor pull the permits. This keeps the liability for the work with the professional service.
