Permits for a ADU in Carmel Valley
The City of San Diego requires a building permit for every ADU and junior ADU, with no exemptions. Its rules are summarized in Information Bulletin 400. Source: City of San Diego, Information Bulletin 400.
Coastal Zone: parts of Carmel Valley are inside the California Coastal Zone. Projects there can need a coastal development permit on top of the building permit, which adds review time. We check your parcel before design starts.
State timeline: when there is already a home on the lot, California law (Gov. Code §66317) requires the city or county to approve or deny a complete ADU application within 60 days.
We prepare the plan set, submit it, answer plan-check corrections, and schedule every inspection through final sign-off.
What your Carmel Valley ADU includes
- Detached & attached ADUs. Standalone backyard units or additions attached to your existing home, designed to maximize rentable square footage on your lot.
- Permit & plan coordination. We manage the entire San Diego ADU permitting process — code compliance, plan checks, and approvals — so you don't have to.
- Built for rental income. Every ADU is designed around return: livable layouts, durable finishes, and a footprint that appraises and rents.
- Free 3D rendering. See your finished ADU before we build it, with our in-house design software — included free for every new client.
Featured project: the Curlew St lot split
At 3680–3682 Curlew St in San Diego, we added a second story to the main house and converted the garage into a separate unit. The owner now has two rentable addresses on one lot. It's the project we point Carmel Valley homeowners to first, because it shows our permitting, structural, and finish work in one place.
