ADUs & Additions in Eastvale

City of Eastvale Community Development Department, Building Division. The Building Division of the Community Development Department reviews plans, issues permits and inspects residential work, with applications filed through the city's Accela permit portal. Under Zoning Code section 120.05.120, pools, spas and ground-mounted pool equipment may not sit in the required front or street-side yard, and pools and spas keep three feet from interior and rear property lines. Accessory structures other than pools may total no more than half the home's habitable floor area, accessory structures other than patio covers may occupy no more than 30 percent of the required rear yard, and a patio cover inside the required rear or street-side yard is limited to nine feet in height. A Planned Residential Development or a specific plan sets its own setbacks in place of the base zone. For a new ADU, section 120.04.010 calls for four-foot side and rear setbacks and all-weather emergency access, and requires fire sprinklers only where the main house requires them. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check.

Most of Eastvale was built after 1990 and is suburban in design. Where the base R-1 zone applies, lots are at least 7,200 square feet, 60 feet wide and 100 feet deep, with 20-foot front, 5-foot interior side, 10-foot street side and 10-foot rear setbacks; tracts approved as Planned Residential Developments or under specific plans carry their own standards, and The Enclave, a gated community, was planned with single-family lot minimums ranging from 2,030 to 7,200 square feet. The Chandler Area is the exception, with homes on large lots alongside horse corrals, barns and farm animals. One local condition that shapes the work: The General Plan identifies Eastvale as having moderate to high susceptibility to liquefaction, highest where groundwater lies less than 10 feet below the surface, and calls site-specific geotechnical study the only practical and reliable way to judge a given site, so a soils report comes before pool shell and footing design.

All of it, including The Enclave, Chandler Area and Downtown Eastvale. 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.
