ADUs & Additions in Newport Beach

City of Newport Beach Community Development Department, Building Division. Residential plan check, permits and inspections run through the Building Division permit counter at the Civic Center on Civic Center Drive. Most harbor, island, peninsula and bluff property sits inside the Coastal Zone, and the city has issued its own Coastal Development Permits since its Local Coastal Program Implementation Plan took effect on January 30, 2017; certain geographic areas and project types remain appealable to the California Coastal Commission.

Dock and pier construction permits for work bayward of the bulkhead are processed separately by the Public Works Department, not the Building Division. Newport Coast and several bluff and island communities layer HOA architectural review on top of city review, and setback encroachments typically require a Modification Permit.

We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

Lot character swings hard between narrow, deep alley-served parcels on the islands and peninsula and larger graded hillside pads in Newport Coast and the bluff tracts. Rear yards on the older lots are compact and almost always accessed through a side gate or alley rather than a driveway.

One local condition that shapes the work: Groundwater can be shallow on the islands and the peninsula, so the geotechnical report may call for dewatering during pool and spa excavation and hydrostatic relief in the finished shell. Dewatering discharge is regulated.

All of it, including Corona del Mar, Balboa Island, Balboa Peninsula and Newport Coast. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site.

Detached ADU: generally $150,000 to $400,000+ across Southern California. 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.
