ADUs & Additions in Norco

City of Norco Building and Safety Division. Residential permits are issued by the City of Norco Building and Safety Division, whose pool and spa submittal checklist calls for three sets of plot plans and two stamped, signed sets of structural plans, with the plot plan showing the lot's Primary Animal Keeping Area (PAKA) or animal keeping area and its required access, dimensioned. The checklist's Norco-specific requirements are to assume expansive soil, keep five feet clear from the water's edge to any obstruction and install no P-traps, and a Contractor Business License Verification Form and an Owner's Declaration Form must be approved before the permit is issued. In the A-1 zone, structures may cover no more than 40 percent of the flat pad, and in-ground pools and spas count toward building coverage together with a five-foot coping area around their perimeter. Under the city's ADU checklist, a detached ADU may have up to 1,000 square feet of living area, an ADU tops out at 16 feet at the peak, its exterior materials, colors, roof pitch and architecture must match the main house, and a detached unit must be metered separately for city water. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

Large and agricultural by design: lots of 20,000 square feet or more make up almost half of Norco's incorporated land, and the A-1 zone's minimum is 20,000 square feet for lots created before Ordinance 977 took effect on September 6, 2014 and 21,780 net square feet for lots created since, with a flat pad of at least 19,600 square feet on each new lot. East of the I-15, most lots exceed 20,000 square feet and hold low, one-story houses set back behind split-rail, chain link or picket fences, while lots on the steeper slopes of the Norco Hills and Norco Ridge Ranch areas are 20,000 square feet or less, and residential lots west of the freeway are 20,000 square feet. One local condition that shapes the work: The city's pool and spa checklist directs designers to assume expansive soil, so pool shells, decking and flatwork are engineered for soil movement from the outset.

All of it, including Norco Hills, Norco Ridge Ranch and Sixth Street Corridor. 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.
