Most ADU projects in Stanton run between $180,000 and $320,000 for a detached unit before site work, which is the honest range to have in your head before you start calling builders. Stanton’s mix of 1950s-era ranch homes and newer infill lots means no two properties respond to an ADU the same way: some need significant grading, others slip into a side yard with room to spare. We’re Sutton ADU Builders, part of the Threshold Group family since 2006, and we handle ADUs, home additions, and room additions across Stanton with a written price locked in before any tool leaves the truck. Call us at (472) 248-8213 when you’re ready to talk numbers, not vague estimates.
Why Stanton Homes Are Different
Stanton sits on flat, compacted Orange County soil that drains slowly after winter rains, which affects how we design foundations and site drainage for any new structure. A lot of the housing stock dates from the 1950s and 1960s, so we’re regularly working around original cast-iron drain lines, undersized electrical panels, and shallow footings that need upgrading before an ADU or addition can be permitted. The city’s lots are smaller than what you’ll find in Cypress or Buena Park, often 5,000 to 6,000 square feet, which means a setback (the required gap between your new structure and the property line) can make or break a floor plan. Stanton also has a patchwork of older neighborhoods near Cerritos Avenue and Beach Boulevard where homes sit close together, so we spend real time on sight-line privacy and window placement so your new unit doesn’t feel like it’s looking into the neighbor’s kitchen.
Our Main Stanton Services
Three jobs make up almost all of our Stanton work: full home additions, ADU construction, and room additions. Each has its own page with pricing, timelines, and what to expect, linked below.
Home Addition Contractor in Stanton
A home addition in Stanton usually means extending the back or side of a 1950s ranch to add a primary suite, a family room, or a second bathroom. The local wrinkle is tying new framing into old: many Stanton homes have settled unevenly over the decades, so we spend the first day measuring the existing slab and roof line before we finalize the build plan. We also coordinate with the city on setback variances where the lot is tight. See the full scope and pricing on our Home Addition Contractor in Stanton page.
ADU Builders in Stanton
Detached ADUs in Stanton work well on lots where the main house sits forward and the rear yard is underused, which describes a large share of homes off Katella Avenue and within walking distance of Stanton Park. We handle site prep, foundation, utility runs, and the full build, and we’re fluent in prefab options like Abodu and Dvele when a faster timeline matters. One thing we flag early: Stanton’s soil often means a deeper gravel base and additional drainage around the ADU pad, which we include in the written price. Details are on our ADU Builders in Stanton page.
Room Addition Contractor in Stanton
Room additions in Stanton are often the fastest way to add square footage without the full ADU permit path. Think of converting an enclosed porch into a livable office, adding a bedroom over an existing garage, or pushing out a wall for a larger kitchen. On older Stanton homes, we commonly find knob-and-tube wiring sections and unpermitted past work that must be corrected before inspection. The good news: we write all of that into the upfront quote, so there’s no surprise invoice mid-project. Read the specific scope on our Room Addition Contractor in Stanton page.
