ADUs & Additions in Anaheim Hills

City of Anaheim Planning and Building Department, Building Division. Anaheim Hills is part of the City of Anaheim, so residential permits are issued by the Planning and Building Department's Building Division, not by a separate city or by the county. Grading plans must comply with Anaheim Municipal Code Chapter 17.06, Grading, Excavations and Fills in Hillside Areas, and the city publishes a specific hillside grading plan procedure that requires security in the form of a surety bond, letter of credit or cash deposit, plus a landscape and irrigation bond for slopes over five feet with a minimum bond amount. Most of the area east of the 55 and 91 interchange falls under the Scenic Corridor (SC) Overlay Zone in Chapter 18.18 of the zoning code, which adds design and landscape standards. Portions of the canyon are mapped as Very High Fire Hazard Severity Zone. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.

Hillside pads carved into ridgelines, with flat frontage, a home near the street and a rear yard that drops away. Older Peralta Hills parcels are large, semi-rural and gently sloped; the newer ridge tracts are tighter with dramatic grade change. In practice that means ridge and canyon pads were created with substantial engineered fill, so verifying fill depth and compaction reports before setting a shell elevation is essential to avoid redesign mid-project..

All of it, including Anaheim Hills Estates, Peralta Hills, The Summit, Sycamore Canyon. We are based in Los Angeles at Cahuenga Pass, so Anaheim Hills 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.
