A fixed-price addition project from our Plano-based DFW team serving Carrollton 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 Carrollton typically runs $120,000 to $400,000, depending on square footage, whether you build out at grade or add a second story, and how much the new space ties into existing plumbing, electrical, and roofing. We quote every addition as a fixed price, so your number is set before demolition begins. Permits are pulled through the City of Carrollton’s Building Inspection department via its CityServe portal, and a key local driver is that the city requires every contractor (general, plumbing, mechanical, and electrical) to be Texas-licensed AND registered with the City of Carrollton before a permit is issued. A second Carrollton-specific cost factor: many homes sit on mature, tree-lined mid-century lots with limited side-yard room, so additions here often go up or to the rear, and matching the original 1980s brick and rooflines on an established home adds detail work that affects scope and price. For a line-item look at where the money goes, see our DFW remodel cost guide.
Carrollton is a built-out suburb where the median home dates to roughly 1987-88, so most lots already carry a 35-to-40-year-old house with no easy way to grow but up or out. That is exactly why home additions are one of the most-requested projects we do here. The 1950s-1980s ranch homes in the older east and southeast sections near I-35E have efficient but tight single-story footprints, while the 1980s-90s traditional brick two-stories and the master-planned homes out in Castle Hills often need a primary-suite expansion, a bonus room, or a bumped-out family room rather than a move. UHS Remodeling designs and builds room additions, second-story and primary-suite additions, and in-law/garage conversions across Carrollton on a fixed-price contract, backed by 5,875+ DFW projects since 2014 and a 3-year workmanship warranty.
We build home additions across Carrollton, including Castle Hills, Josey Ranch, Country Place, Indian Creek, Valley Ranch, Saddlebrook Estates, and the older neighborhoods near Historic Downtown Carrollton.
“An addition in Carrollton 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.
