A fixed-price addition project from our Plano-based DFW team serving Wylie 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 Wylie typically runs $120,000 to $400,000, depending on whether you are adding a single room, a primary-suite wing, or a full second story, plus the finish level and how much the new space ties into existing systems. Permits for additions are pulled from the City of Wylie Building Inspection Department, with a stated residential turnaround of 5 to 10 business days. A Wylie-specific cost driver: because most homes sit on early-2000s tract lots in master-planned communities, footprint expansions quickly run into lot setbacks and HOA architectural review, so many additions go up rather than out, and a second story adds structural and foundation-reinforcement engineering that raises the budget. Tying new HVAC, plumbing, and electrical loads into a 15-to-25-year-old home can also require panel or system upgrades. UHS works on a fixed-price model with a 1-year workmanship warranty, so your number is locked before demolition begins. 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.
Most Wylie homes were built during the post-2000 boom that grew the city from about 15,000 residents to nearly 57,500 by 2020, which means the typical single-family home here is roughly 20 years old and around 2,497 square feet. For families who love their master-planned neighborhood but have outgrown the original floor plan, a home addition is often the smartest move. Across Woodbridge, Inspiration, Dominion of Pleasant Valley, Kreymer East, and Bozman Farm Estates, we add primary-suite expansions, second stories, extra bedrooms, sunrooms, and bonus rooms that match the brick and stone-veneer, Texas-transitional style these production-built subdivisions share. UHS Remodeling has remodeled homes across DFW since 2014, and in Wylie an addition lets you stay in Wylie ISD and keep your Lake Lavon lifestyle while gaining the square footage you need.
We build home additions across Wylie, including Willow Bend, Legacy West, Deerfield, Hunters Glen, Russell Creek, and West Wylie 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 Wylie 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 Wylie 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 Wylie 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 Wylie 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. Any home addition inside Wylie city limits requires a permit from the City of Wylie Building Inspection Department, since the work involves structural, foundation, and system changes. The city’s stated turnaround for residential permits is 5 to 10 business days. If your home is in a master-planned community such as Woodbridge, Inspiration, or Dominion of Pleasant Valley, you will likely also need HOA architectural approval.
It depends on your lot. Many Wylie homes were built in the early 2000s on production-builder lots where setbacks and HOA rules limit how far you can extend the footprint, so a second-story addition is often the better path. Building up preserves yard space but requires foundation reinforcement and structural engineering, which UHS factors into your fixed price during planning.
Home additions in Wylie generally range from $120,000 to $400,000. A single-room or bonus-room addition sits at the lower end, while a primary-suite wing or full second-story addition reaches the upper end. UHS prices every Wylie project on a fixed-price model with a 1-year workmanship warranty, so the cost is set before work starts.
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 Wylie 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 Wylie 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 Wylie Building Inspection Department requires permits for any addition. Some Wylie 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 Wylie 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 Wylie 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.
