ADUs & Additions in Villa Park

City of Villa Park Building and Safety (building services contracted to VCA Code). Residential permits run through the city's Building and Safety department, which contracts VCA Code for building services and takes building permit and plan check applications through an online portal, with plan check sets submitted as PDFs. The zoning code requires site plan review for all new development, in which the Planning Director weighs the design's compatibility with surrounding homes, and no building or grading permit is issued until the site plan is approved. A pool must sit at least three feet from every property line and outside the front-yard and street-corner areas where fences are held to three and a half feet, while pool and spa equipment placed in an interior side or rear setback needs site plan approval, must stay three feet off the property line and cannot exceed 50 dBA at the closest property line. Detached ADUs are capped at 1,200 square feet on lots under an acre and 1,500 square feet on an acre or more, and a recreational court in the E-4 estate zone requires a conditional use permit granted after a public hearing. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

A predominantly residential city of single-family homes with very few vacant lots left. At incorporation in 1962 a single 20,000-square-foot small estates zone covered the whole city; a later change carved out a small westerly band of 8,000- and 12,000-square-foot lots as a transition from Orange, and the north and east remain zoned entirely for 20,000-square-foot small estate lots. Newly created E-4 lots must be at least 20,000 square feet, lots of 17,000 square feet and up carry a 30-foot front setback, and the rear setback is 25 feet at every lot size. One local condition that shapes the work: CAL FIRE's Fire Hazard Severity Zone map for Local Responsibility Areas, dated March 24, 2025, shows most of the city as non-wildland, but land along the northeastern edge falls in Moderate, High and Very High zones, so the zone is confirmed parcel by parcel before decking, vents and exterior materials are chosen.

All of it, including The Orchards, Villa Park Road, Taft Avenue and Santiago Boulevard. 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.
