A fixed-price addition project from our Plano-based DFW team serving Rowlett homeowners, with designers, project leads, and tradespeople who finish on the day they said they would. Eleven years, one promise: your quote is your price.
A home addition in Rowlett typically runs $120,000 to $400,000, depending on whether you are adding a single room, a primary suite, or a full second-story or wing. Tying new square footage into a 1990s-era structure is what drives cost: permits in Rowlett go through the City of Rowlett Building Safety division (under Community Development) via the MyGov online portal, and because the city is split between Dallas County (west of Dalrock Road) and Rockwall County (east of it), a plat must be on file with the correct county before your building permit is issued. That two-county requirement, plus new foundation work, structural framing, and extending plumbing, electrical, and HVAC from an older home, adds engineering and inspection steps a cosmetic remodel never touches. UHS prices every Rowlett addition as a fixed figure up front, so the number you approve is the number you pay. For a line-item look at where the money goes, see our DFW remodel cost guide.
We handle survey, setbacks, engineering, HOA and permits before demolition. If your lot cannot take the footprint, you will hear it at the first walkthrough.
Fixed scope and a written schedule before anyone breaks ground in your yard.
Many Rowlett homes were built during the city’s growth wave after Lake Ray Hubbard was completed in 1971, and the citywide median construction year sits around 1997. That means a large share of houses here are now 25 to 40 years old and short on space for how families actually live. A home addition is how Rowlett owners expand without leaving a neighborhood they love. On the brick-and-stone ranch and “New Traditional” two-story homes common in established South Rowlett, a primary-suite or bonus-room addition opens up footprints that were generous in the 1990s but feel tight today. In master-planned communities like Waterview and Trails at Cottonwood Creek, and on waterfront lots near the lake, additions let homeowners add square footage on lots they already own. UHS Remodeling has remodeled homes across DFW since 2014, on a fixed-price model backed by a 1-year workmanship warranty.

City of Rowlett plan review, HOA architectural committee, energy code compliance. Average 3-5 weeks.
Foundation, framing, roof tie-in, MEP rough-in, insulation, drywall, finish-out. 12-22 weeks per scope.

Design and structural engineering run first, and city plan review plus the HOA architectural committee average three to five weeks before anyone breaks ground.
“An addition in Rowlett 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.”

Which one is right depends on your lot line, your slab and your roof — not on a catalog.
Renderings from our design studies — the finished Rowlett projects are above.
Ranges include foundation, framing, roof, systems and finishes — everything but landscaping.
All ranges include architectural drawings, engineering, materials, labor, permits, foundation, framing, MEP, finishes, and 1-year warranty. Sourced against NARI Cost vs. Value 2025 and your city building code requirements.
Single-room addition (250-450 sqft): bedroom, office, sunroom. Exterior match, standard finishes, full MEP.
Master wing or large family room (450-800 sqft): primary suite + bath, formal dining add-on, or great room expansion.
Second story or full custom (800+ sqft): structural foundation work, full second floor, matched exterior, custom millwork.
Additions live or die on setbacks, easements and lot coverage — and every DFW city writes those rules differently. We have permitted additions across Rowlett and the neighboring cities, which means we can tell you in one visit whether the footprint you want is legal on your lot.
We deliver home addition across the northern DFW suburbs. See our home addition in Frisco, Allen, and McKinney.

Yes. Additions are permitted through the City of Rowlett Building Safety division (under Community Development) via the MyGov online portal. Because Rowlett spans Dallas County west of Dalrock Road and Rockwall County east of it, your plat must be on file with the correct county before the building permit is issued. UHS handles the permitting and the structural, plumbing, electrical, and mechanical inspections an addition requires.
Yes. Much of Rowlett’s housing dates to the 1980s-90s, and we regularly add primary suites, bonus rooms, and second stories onto ranch and New Traditional homes in areas like South Rowlett. On lakefront lots near Lake Ray Hubbard and in master-planned communities such as Waterview or Bayside, we coordinate any required HOA architectural review alongside the city permit before construction starts.
Most Rowlett home additions run $120,000 to $400,000, depending on size and complexity — a single-room bump-out sits at the lower end, while a primary-suite or second-story addition lands higher. Tying new framing, foundation, and plumbing/electrical/HVAC into a 1990s-era home is the main cost driver. UHS gives you one fixed price up front, backed by a 1-year workmanship warranty.
Single-room additions take 10-18 weeks including permitting. Multi-room wing additions run 6-11 months including design and permitting. Second-story additions and estate-scale projects take 10-16 months.
Yes, second-story additions are permitted in most Rowlett residential zones, subject to maximum building height, setback, and lot coverage requirements. Not every original foundation is adequate for a second-story load – we run a structural feasibility check early in design.
Yes. Garage conversions are one of the most cost-effective Rowlett additions because the foundation, walls, and roof already exist. We convert garages into home offices, playrooms, gyms, and in-law suites. The conversion requires a permit, new flooring, and HVAC/electrical tie-in.
We source matching or visually identical exterior materials – brick from the same manufacturer or salvaged brick yards, stone matched to the existing, siding and roofing matched. Matching materials may add 3-6 weeks to procurement but ensures the addition does not look bolted-on.
Yes. The City of Rowlett Building Inspection Department requires permits for any addition. Some Rowlett neighborhoods also have HOA architectural review requirements. UHS handles both submissions.
Usually, yes – especially for rear additions and garage conversions that do not break into the existing home until the final tie-in phase. For second-story additions, most homeowners relocate for 4-10 weeks during structural phases.
Yes. Every addition we build is engineered by a licensed Texas structural engineer. We handle the full foundation scope and all structural framing including steel beams, load transfers, and second-story floor systems.
Yes. A well-designed Rowlett addition typically returns 70-90% of project cost on resale. Master suite expansions and kitchen/great room extensions return close to 100%. An addition also lets a family stay in the neighborhood rather than selling and moving.

North Texas sits on highly expansive clay soil that swells during wet months and shrinks during summer droughts, which can shift foundations by several inches over seasonal cycles. That is why every room addition we build in Rowlett and Frisco starts with a foundation plan designed by a licensed structural engineer for the specific soil conditions of the lot. Typical solutions include steel-reinforced slab foundations and concrete piers that reach below the active soil zone, so the new addition moves with the original home instead of pulling away from it. Skipping this step is the most common cause of cracked brick, sticking doors, and separated rooflines in DFW additions.
Tell us what you need more of and we’ll walk the lot, check the setbacks, and give you an honest budget range before you commit to anything.
