ADUs & Additions in San Clemente

City of San Clemente Community Development Department, Building Division. The Community Development Department at 910 Calle Negocio is organized into administration, Planning, and Building and Code Compliance; the Building Division handles plan review, permit issuance, counter services and inspections. The city's Local Coastal Program Land Use Plan was certified by the California Coastal Commission in August 2018, and the LCP update was intended to let property owners obtain a single coastal permit from the city rather than going to the Commission, with appeal rights preserved for certain areas and project types. Blufftop parcels draw scrutiny on setbacks, bluff erosion and preservation of natural landforms, and canyon and slope lots typically require geotechnical review. Talega, Sea Summit and other master-planned tracts add association design review before city submittal. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.

Terraced hillside lots stepping toward the ocean dominate, with graded pads, rear slopes and slope easements. The older beach-adjacent grid west of the freeway has smaller, tighter lots with limited access. In practice that means most buildable pads were created by cut-and-fill grading, so a pool or ADU often sits partly over deep engineered fill and needs deepened footings, piles or a structurally supported shell..

All of it, including Talega, Rancho San Clemente, Forster Ranch, Sea Summit at Marblehead. We are based in Los Angeles at Cahuenga Pass, so San Clemente is a short run for our crews rather than a job we service from out of the area.

Detached ADU in this market generally runs $150,000 to $400,000+. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.

Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.

Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.

California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.

Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
