Hillside grading procedures, bonded slope planting and the Scenic Corridor overlay all touch what a backyard can become, and pads carved into the ridgelines often mix native cut with deep engineered fill. Wildfire exposure is real across much of the area. We plan pool shells, retaining walls and ADU foundations around the fill line, not around a lot line. 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. We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, [CSLB license #1119054](https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/LicenseDetail.aspx?LicNum=1119054) . Permits in Anaheim Hills: 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. The Public Works Department's hillside grading plan procedure requires security (surety bond, letter of credit or cash deposit) and a landscape and irrigation bond covering slopes over five feet high, with a $10,000 minimum bond amount. Property east of the SR-55/SR-91 interchange and south of the railroad line, outside the Anaheim Canyon Specific Plan area, is in 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. Permit details checked September 2026 against [City of Anaheim](https://www.anaheim.net/5252/Building-Division) and [Anaheim Municipal Code](https://codelibrary.amlegal.com/codes/anaheim/latest/anaheim_ca/0-0-0-66500) . Rules change, so we confirm them again for your parcel.

Questions #### What Anaheim Hills Homeowners Ask Who issues the permits for this work 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. The Public Works Department's hillside grading plan procedure requires security (surety bond, letter of credit or cash deposit) and a landscape and irrigation bond covering slopes over five feet high, with a $10,000 minimum bond amount. Property east of the SR-55/SR-91 interchange and south of the railroad line, outside the Anaheim Canyon Specific Plan area, is in 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 plan check. What makes building in Anaheim Hills different? 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. One local condition that shapes the work: 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. Which parts of Anaheim Hills do you work in? All of it, including Anaheim Hills Estates, Peralta Hills, The Summit and Sycamore Canyon. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site. What does an ADU or addition cost in Anaheim Hills? 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. How long does an ADU take start to finish? 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. Is a garage conversion cheaper than a detached ADU? 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. Can I rent the ADU out? 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. Do you handle the permits? 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. #### More Services in Anaheim Hills [Pool & Spa Remodeling in Anaheim Hills](https://www.remodelyourvibe.com/services/swimming-pool-spa/anaheim-hills) [Backyard & Outdoor Living in Anaheim Hills](https://www.remodelyourvibe.com/services/exterior-remodeling/anaheim-hills) [Everything we build in Anaheim Hills](https://www.remodelyourvibe.com/service-areas/anaheim-hills) #### ADUs & Additions Nearby [ADUs & Additions in Yorba Linda](https://www.remodelyourvibe.com/services/adus-additions/yorba-linda) [ADUs & Additions in Corona](https://www.remodelyourvibe.com/services/adus-additions/corona) [ADUs & Additions in Tustin](https://www.remodelyourvibe.com/services/adus-additions/tustin) [ADUs & Additions in Irvine](https://www.remodelyourvibe.com/services/adus-additions/irvine) [ADUs & Additions in Costa Mesa](https://www.remodelyourvibe.com/services/adus-additions/costa-mesa) [ADUs & Additions in Orange](https://www.remodelyourvibe.com/services/adus-additions/orange) Planning Guides #### Before You Build in Anaheim Hills Costs, materials and process notes from our own projects.
