A fixed-price addition project from our Plano-based DFW team serving Dallas homeowners, with designers, project leads, and tradespeople who finish on the day they said they would. Eleven years, 5,875 projects, one promise: your quote is your price.
A home addition in Dallas typically runs $120,000 to $400,000, depending on whether you’re adding a single room, a primary suite, or a full second story, plus how the new footprint ties into the existing structure. Permits for added square footage go through the City of Dallas Permit Center at the Oak Cliff Municipal Center, submitted via the city’s DallasNow / Develop Dallas online portal. A major Dallas-specific cost driver is the age of the housing stock: with a median build year around 1981 and pockets of pre-1940 homes in East Dallas and Oak Cliff, additions often require upgrading existing foundations, wiring, and plumbing to current code so the old and new sections work as one. Matching original brick and rooflines on these established homes — and working within tight inner-city lots in areas like Lakewood and the M Streets — adds to the budget versus a suburban new build. Our fixed-price model locks the number before work begins. For a line-item look at where the money goes, see our DFW remodel cost guide.
Adding square footage in Dallas means building onto homes that are, on average, already four decades old — the city’s median construction year sits around 1981. In neighborhoods like Lakewood, the M Streets (Greenland Hills), and Kessler Park in Oak Cliff, that often means expanding a 1920s-1940s Tudor or cottage, while Preston Hollow and North Dallas owners typically extend larger homes on bigger lots. A Dallas home addition is rarely a blank-slate build: it’s a tie-in to an existing older structure, matching original brick and rooflines, and frequently a primary-suite, second-story, or great-room expansion on a desirable inner-city lot where moving isn’t an option. UHS Remodeling has completed 5,875+ DFW projects since 2014 with a fixed-price model and a 3-year workmanship warranty, so the scope — and the cost — is settled before we break ground.
We build home additions across Dallas — Lakewood, Lakewood Heights, the M Streets (Greenland Hills), Preston Hollow, Kessler Park and the rest of Oak Cliff, and the broader East Dallas area.
“An addition in Dallas is half permits, half craft. We pre-meet with the city’s plan review before drawings are stamped — that’s why our additions break ground 6 weeks after contract, not 14.”
All ranges include design, materials, labor, permits, and 3-year warranty. Sourced against NARI Cost vs. Value 2025 regional benchmarks.
