A fixed-price addition project from our Plano-based DFW team serving Rockwall 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 Rockwall typically runs $120,000 to $400,000, with the final number set by square footage, whether you build out or up, and how much of the kitchen, plumbing, and HVAC the new space ties into. Permits for additions inside the city limits go through the City of Rockwall Building Inspections Department; properties in unincorporated Rockwall County or neighboring cities like Heath, Fate, and McLendon-Chisholm permit through their own jurisdictions instead. A Rockwall-specific cost driver is the lake itself: additions on waterfront lots in communities such as Chandlers Landing often sit on older, custom, sometimes sloped lakeside parcels where foundation engineering, drainage near Lake Ray Hubbard, and matching original custom finishes add cost compared with a flat suburban lot in a 2000s-era subdivision. UHS Remodeling quotes every Rockwall addition as a fixed price and backs the work with a 1-year workmanship warranty. 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.
Rockwall homeowners reach a point where the early-2000s floor plan that fit a young family no longer fits the life inside it. With roughly 79% of homes here being single-family detached and a median build year around 2003, most Rockwall houses are now about twenty years old: solid bones, but short on the square footage today’s families want. That’s why a home addition often beats relocating, especially when staying put means keeping a Lake Ray Hubbard address and Rockwall ISD zoning, the two factors most cited as driving local home value. UHS Remodeling builds room additions, primary-suite expansions, second stories, and great-room bump-outs across Rockwall, from suburban communities like Rockwall Downes and Saddle Star to the custom waterfront homes of Chandlers Landing on Lake Ray Hubbard. With DFW experience dating to 2014 and a fixed-price model, we expand your footprint without a teardown.
We build home additions across Rockwall, including Willow Bend, Legacy West, Deerfield, Hunters Glen, Russell Creek, and West Rockwall Estates.
Site walk, scope (bedroom, master wing, second story), zoning + setback review, budget alignment.
Architectural drawings, structural engineer review, exterior match planning, MEP routing.
City of Rockwall 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.
Final inspection, punch list, certificate of occupancy filing, 1-year warranty active.
New slab and framing tied into the existing structure.
Matched brick and tinted mortar at the old-to-new seam.
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 Rockwall 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.”
From our Plano home addition case study — engineering, permits and the brick match. View all →
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 Rockwall 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 Rockwall 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 inside the city limits are permitted and inspected through the City of Rockwall Building Inspections Department, and because an addition involves structural, foundation, and trade work, you’ll typically see multiple inspections. Homes in unincorporated Rockwall County or in nearby cities like Heath, Fate, McLendon-Chisholm, or Rowlett permit through their own jurisdiction. UHS Remodeling handles permitting as part of the project.
Yes. We build additions on Lake Ray Hubbard waterfront homes, including the custom and older properties in Chandlers Landing. These lakeside lots can involve extra foundation engineering, drainage considerations near the water, and careful matching of original custom finishes, all of which UHS Remodeling accounts for in a fixed-price quote and our 1-year workmanship warranty.
Most home additions in Rockwall run between $120,000 and $400,000. The range depends on the size of the new space, whether you build out on the lot or add a second story, and how much new plumbing, electrical, and HVAC the addition requires. UHS Remodeling provides a fixed-price quote so your Rockwall number is locked in before work begins.
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 Rockwall 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 Rockwall 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 Rockwall Building Inspection Department requires permits for any addition. Some Rockwall 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 Rockwall 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 Rockwall 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.
