Benson ADU Builders designs and builds accessory dwelling units, home additions, and room additions across Madera, CA. Most Madera projects happen on large suburban lots east of Highway 99, where 15 to 20 feet of unused side yard changes the math on detached ADU placement. Hot summers, cool foggy winters, and a split between 1920s bungalows and newer slab-on-grade tract homes mean every job starts with a site walk and a written price before any work begins. Call (559) 206-2363 to schedule a free estimate.
Why Madera Homes Are Different

Madera’s post-2000 suburban expansion happened fast, with former farmland converted into stucco tract subdivisions east and north of the older core. The result is a housing stock with two distinct personalities. The 1920s to 1950s bungalows near downtown sit on raised foundations with attic access, which affects how we tie a new ADU into existing framing and how we route plumbing. The 2000s and 2010s stucco homes are slab-on-grade with tile roofs, which pushes foundation work and roof transitions in a different direction entirely.
The big opportunity in Madera’s newer subdivisions is side yard. Builders left a surprising amount of unused space between homes, often 15 to 20 feet. That makes detached ADUs with zero lot line setbacks the most popular option we quote. No alley access on these lots means utility routing and setback planning require more thought than in older central neighborhoods, but the space is there if you know how to use it. Madera’s 100°F-plus summer days also shape the build: reflective roofing, high-efficiency cooling, and careful attic ventilation are standard in our specs, not upgrades. Winter frost can hit uninsulated water lines, so we account for that in every plan.
Our Main Madera Services
Most Madera homeowners call us for one of three projects: a new ADU, a full home addition, or a single room addition. Each has its own Madera page with local pricing, timelines, and the conditions that affect the quote.
ADU Builders in Madera
Building an ADU in Madera usually means a detached unit in the side yard of a newer subdivision home or a garage conversion on an older central lot. We walk the site, check setbacks, and put a written price in front of you before anything gets signed. Madera’s mix of slab-on-grade and raised-foundation homes means the foundation plan varies block by block. See ADU Builders in Madera for full pricing and the specific permits Madera requires.

Home Addition Contractor in Madera
A home addition in Madera often means extending a single-story stucco tract home outward, which requires matching roof pitch, stucco texture, and tile style so the addition doesn’t look bolted on. On older bungalows, the job shifts to foundation upgrades and tying into existing attic framing. We quote the full scope in writing before work starts. Details on pricing and process are on our Home Addition Contractor in Madera page.

Room Addition Contractor in Madera
A single room addition, like a primary bedroom or a home office, runs into the same Madera conditions as a full addition, just on a smaller footprint. On slab-on-grade homes we match the existing slab elevation and roof line. On raised foundations we inspect the framing underneath before quoting, since older Madera homes can hide pier and beam work. See Room Addition Contractor in Madera for the full breakdown of costs and what to expect.

In Madera, the two biggest price movers are foundation type and utility routing. Raised foundations on older central homes cost less to tie into, while slab-on-grade new builds save on demolition. Routing sewer and electrical without alley access on newer lots adds labor hours. Every quote from Benson ADU Builders is a written price before work starts, with no change orders billed after the fact.
