Building an ADU in Beverly Hills means working with tight lots, strict design review, and homes that sit on some of the most scrutinized real estate in Southern California. We’re Sutton ADU Builders, and we handle detached ADUs, garage conversions, and room additions across Beverly Hills with a written price before any work starts and a 365-Day Done Right Promise covering workmanship for a full year. When you need straight answers about cost, permitting, and who exactly shows up at your door, call (472) 248-8213.
Why Beverly Hills Homes Are Different
Beverly Hills lots are often narrower than they look from the street, and many of the older homes south of Santa Monica Boulevard sit on parcels that leave little room between the main house and the property line. That makes setbacks (the required gap between your new structure and the property line) the single biggest factor in whether a detached ADU fits at all, or whether a garage conversion is the smarter move. Soil conditions vary across the city, and the hillside areas north of Sunset require foundation work that flatland lots don’t. Beverly Hills also has its own design review process that goes well beyond standard California ADU law; the city cares about how a structure looks from the street, not just whether it meets state size limits. If you’re in the flats near Wilshire or up in the Trousdale area, the rules that shape your project won’t be identical. We plan for that from the first site visit.
Our Main Beverly Hills Services
Most Beverly Hills homeowners call us about one of three projects: adding square footage to the main house, building a detached ADU in the rear yard, or converting an existing room or garage into living space. Each has its own page with local pricing and detail.
Home Addition Contractor in Beverly Hills
A home addition in Beverly Hills usually means extending a kitchen, adding a primary suite, or pushing out a living area on a lot where moving isn’t something anyone wants to do. The challenge here is blending the new roofline and stucco or siding with a house that was often built decades ago and has settled into its own character. We handle the structural work, the city submittals, and the finish details, and we give you a written line-item price before demolition day. Home Addition Contractor in Beverly Hills has cost ranges by project type.
ADU Builders in Beverly Hills
Detached ADUs work well on Beverly Hills lots that have usable rear yard space and enough separation from the main house to meet fire and setback rules. We build both stick-frame ADUs and prefab units from brands like Abodu and Boxabl, which can cut months off the schedule when the lot allows. Garage conversions are the other common path, especially on lots where the garage already sits at the rear property line. ADU Builders in Beverly Hills walks through what fits, what it costs, and how long it takes.
Room Addition Contractor in Beverly Hills
A room addition is the most targeted way to add a bedroom, an office, or a larger family room without reworking the whole floor plan. In Beverly Hills, these projects often involve matching existing hardwood floor lines, extending HVAC runs, and keeping the exterior detail consistent so the addition doesn’t read as an afterthought. We bring the same written-price standard to a single room as we do to a full ADU. Room Addition Contractor in Beverly Hills has specifics on scope and pricing.
