ADU Company in Glen Avon, CA
Sunstone ADU Builders is the ADU company Glen Avon homeowners call when they want a kitchen remodel, a detached backyard unit, or both, handled by one contractor who knows Riverside County permitting inside and out. We focus on kitchen remodeling that adds real value to Glen Avon’s mid-century ranch homes and ADU construction that makes sense on the area’s larger, semi-rural lots. If you’re planning a kitchen upgrade or an ADU in Glen Avon, call (855) 949-1913 for a free estimate.
Why Glen Avon Homes Are Different
Glen Avon sits in unincorporated Riverside County, which changes how every project gets permitted. Homeowners often assume they’re dealing with a city building department, but ADU plan review and inspections here run through county building and safety, and that shapes timelines, setback rules, and what gets approved. The housing stock is mostly mid-century single-story ranchers from the 1950s through the 1970s on generous lots, many with detached garages, RV pads, and older additions that were never permitted. That means two things for our work in Glen Avon: first, garage conversions and detached backyard ADUs are usually the most practical path because the footprint and access already exist. Second, older electrical panels and unpermitted prior work frequently need to be addressed before a project can pass inspection. The summer heat is intense, with Santa Ana winds pushing through the Jurupa Valley, so any kitchen remodel or ADU we build in Glen Avon gets insulation and window placement designed for late July afternoons, not just mild spring mornings. We’ve served Glen Avon since 2011, and the lots here consistently offer something neighboring incorporated cities can’t: actual room to build.
Our Main Glen Avon Services
Most Glen Avon homeowners reach out to us for one of two reasons: they want to add an ADU to a lot that already has the space for it, or they want to bring a tired mid-century bathroom up to modern, rental-ready condition. Here’s what each involves in Glen Avon.
ADU Builders in Glen Avon
Because Glen Avon is unincorporated Riverside County, ADU permits go through the county rather than a city hall, and that process rewards builders who do it every week. We handle detached backyard ADUs, garage conversions, and prefab units from brands like Abodu and Cover, and we finish the interiors in-house so the unit is move-in ready without a second contractor. Existing detached garages and RV access on Glen Avon’s larger lots make detached ADUs genuinely feasible. ADU Builders in Glen Avon
Bathroom Remodeling in Glen Avon
Many Glen Avon homes still have their original 1950s and 1960s bathrooms, which means cast-iron plumbing, small footprints, and walls that hide surprises once demo starts. We scope bathroom remodels for ADU interiors and primary-home upgrades, handling the full job from rough plumbing to tile, fixtures, and finish work under one contract. Older homes here often need venting and waterproofing brought up to current code, and we plan for that from the first walkthrough. Bathroom Remodeling in Glen Avon

Kitchen Remodeling in Glen Avon
Kitchen remodeling in Glen Avon usually means working inside a 1950s or 1960s ranch home where the original layout is tight, the electrical panel is undersized, and the summer heat makes ventilation a real performance issue. Homeowners here are often updating a kitchen in the primary house while planning an ADU on the same lot, and we handle both scopes so the finishes match and the permitting moves together. A Glen Avon kitchen remodel typically runs $25,000 to $60,000 depending on layout changes, cabinet grade, and appliance upgrades. For more on how we approach kitchens, see Kitchen Remodeling.
