Why Sutton ADU Fort Worth Is Richland Hills’s Preferred Home Addition Contractor Company

Richland Hills homeowners keep calling us because we show up the way we say we will. Miles Hartwell runs our Fort Worth operation, and his rule is simple: the person whose name is on the quote is the person you see at the door. Every technician is background-checked, identity-verified, and photo-badged, and we send you their name and photo before they arrive. That matters in a city where most houses were built between 1955 and 1975 and homeowners have spent decades dealing with contractors who promise one thing and send someone else.
We also know the local permit desk. Richland Hills enforces the 2018 International Residential Code with Texas amendments, and city staff expect a stamped wind-load calculation before they’ll issue a permit for any addition. A lot of contractors quote without that engineering, then the permit stalls and the homeowner is stuck. Ours doesn’t stall. We submit the calc with the application, the plan review moves, and you know where you stand before we break ground.
Response time from our Dallas-Fort Worth dispatch office to Richland Hills is typically same-week for estimate visits. We don’t schedule anything we can’t keep.
Bathroom Addition Contractor in Richland Hills
A bathroom addition contractor in Richland Hills is handling more than plumbing and tile – the real work is tying a new wet wall into a 1960s slab or pier-and-beam foundation without disturbing the original structure. Most Richland Hills homes sit on expansive clay soil, which swells and shrinks with rain and drought. We pull a geotechnical report before we pour anything, because a bathroom slab that moves will crack the tile, pop the grout, and leak into the subfloor within two years.
What a mid-range bathroom addition includes
Plan on 60 to 90 square feet of new space, a curbless shower with a linear drain, a 36-inch vanity, recessed lighting, and a vent fan that actually ducts to the exterior, not into the attic. In Richland Hills, that configuration runs roughly $75,000 to $110,000 when the existing foundation passes inspection and we’re not relocating a main drain line. Moving a toilet stack or upgrading a 4-inch cast-iron line under the slab adds $8,000 to $18,000, depending on depth.
Why pier-and-beam houses are kinder to this work
If your home sits on pier-and-beam, the addition goes faster and costs less to tie in. We can run new supply and drain lines through the crawlspace without saw-cutting concrete, which trims $4,000 to $10,000 off the slab-home price. The tradeoff is that older floor joists often need sistering to carry the dead load of tile and a cast-iron tub. We check joist spacing and span tables during the estimate, not after demolition.
Bedroom Addition Contractor in Richland Hills

A bedroom addition contractor in Richland Hills is the one who builds you a space that passes the 110 mph ultimate wind speed design the city reviews against, then keeps quiet when the spring storms roll through. Bedroom additions here almost always trigger a framing inspection, a shear-wall inspection, and a final wind-load sign-off. We run Simpson Strong-Tie H2.5A hurricane ties at every rafter and specify windows that carry ASTM E1996/E1886 missile-impact ratings, because the city checks both.
Adding a primary suite without moving out
Most Richland Hills homeowners add a primary suite at the back of the house, off the existing hallway, so they can stay put while we build. A 320-square-foot suite with a walk-in closet and a private bath runs $165,000 to $240,000 in this market, and the build takes 14 to 18 weeks including permits. We seal the existing house with plastic sheeting and run a negative-pressure fan during drywall, so your living space stays livable.
Second-story additions and what they require
If your lot won’t stretch outward – and many on the older, tree-lined streets near Baker Boulevard won’t – we go up. A second-story addition in Richland Hills requires an engineer to verify that the first-floor walls and existing foundation can carry the new load. On 1950s slab homes without post-tensioning, that often means adding steel columns and a new grade beam, which adds $30,000 to $60,000 to the project. The city won’t issue the permit without the stamped letter, and neither should you build without one.
Trusted Brands We Service in Richland Hills
We work with the product lines that actually hold up in North Texas weather. For Richland Hills homeowners, that means James Hardie HardiePlank lap siding rated to 120 mph winds, Simpson Strong-Tie connectors, and, when a homeowner wants a faster build, prefab shells from Mighty Buildings and Plant Prefab. We also convert Tuff Shed structures into conditioned living space when the existing slab and electrical service can support it. You won’t pay a premium for us to recommend what the code already requires – we stock and order from these manufacturers so lead times stay under four weeks.
Common Home Addition Contractor Problems We See in Richland Hills Homes
- Unpermitted detached garages sidelining conversions. Many Richland Hills lots have garages built in the 70s and 80s without permits, on slabs that were never engineered for living space. We see this constantly – the homeowner wants to convert, but the city requires a new foundation and upgraded electrical before the permit clears.
- Three-tab shingles blowing off in spring hail. Cheap bids spec 3-tab shingles with 2 nails each. Richland Hills storms rip those off in a single season. We install architectural shingles with a 6-nail high-wind pattern and a peel-and-stick underlayment.
- Skylights and windows failing the missile-impact test. The city requires ASTM E1996/E1886-rated glazing on all new openings. A contractor who quotes standard windows will get red-tagged at framing inspection. We spec impact-rated glass from the start.
- Slab grading that ignores expansive clay. Richland Hills soil moves. A slab poured without a geotechnical report and proper moisture barrier will crack within two wet-dry cycles. We won’t pour without the report, period.
Pricing for Home Addition Contractor in Richland Hills, TX
Here’s what honest math looks like in Richland Hills. A bathroom addition runs $65,000 to $125,000. A bedroom addition runs $140,000 to $220,000 for ground-floor work, or $190,000 to $300,000 if you’re going vertical. Full attached additions with living space and a bath land between $185,000 and $365,000. The engineering – stamped wind-load calc, geotechnical report, and structural drawings – accounts for $6,000 to $12,000 of that total, and a cheap quote usually leaves it out. You’ll pay for it later in the permit or the insurance claim. We give you a written price before any work begins, and that number doesn’t move unless you change the scope.

FAQs About Home Addition Contractor in Richland Hills
Richland Hills enforces the 2018 International Residential Code with Texas amendments, and your addition must be designed for a 110 mph ultimate wind speed for Risk Category II structures. That means windows and doors need ASTM E1996/E1886 missile-impact ratings, and the city requires a stamped wind-load calculation before it will issue a permit. Call (682) 255-2399 and we’ll tell you whether your existing plans meet the standard.
Yes. Richland Hills issues building permits per scope of work, and a bedroom addition triggers additional review for egress windows, smoke detection, and shear-wall design that a bathroom addition does not. Bathroom permits focus on plumbing, venting, and moisture barriers. We pull both, plus any electrical and mechanical permits, and handle all inspections. You don’t stand in line at city hall for any of it.
The city’s framing inspection checks roof sheathing thickness, shingle nailing patterns, and the presence of impact-rated glazing. Inspectors look specifically for the 6-nail high-wind shingle pattern and ASTM-rated window labels. We photograph every one of those details before drywall goes up, so if an insurance adjuster asks later, you have documentation. Call (682) 255-2399 for a quote.
Expect a minimum of four inspections: footing and formwork before concrete, framing and shear-wall after the roof goes on, rough-in for electrical, plumbing, and mechanical, and a final building inspection with a certificate of occupancy at the end. On second-story additions, the city also sends an engineer to verify the tie-down system. We schedule every inspection and walk with the inspector on site.
Sometimes, but most detached garages in Richland Hills were built on slabs that don’t meet current habitable-space requirements, and many were never permitted. If the city has no record, you’ll need a new foundation, upgraded electrical service, and often a survey to establish setbacks. That work typically adds $40,000 to $75,000 to the conversion cost. Call (682) 255-2399 and we’ll check your specific lot before you spend money on plans.
On a quiet street off Rufe Snow Drive, we reinforced a 1960s brick ranch’s bedroom addition for a family expanding for aging parents. The original slab had no post-tensioning, so we poured a new monolithic footing with #4 rebar at 12-inch centers, tied into the existing foundation with epoxy dowels. We installed James Hardie HardiePlank lap siding with a 120 mph wind rating and Simpson Strong-Tie H2.5A hurricane ties at every rafter; the inspector verified the tie spacing and nailing pattern before we closed the walls. That’s the standard on every build we do in Richland Hills.
If you’re planning an addition in Richland Hills, start with a conversation, not a contract. Call (682) 255-2399 to schedule a free estimate. We’ll walk the lot, check your existing foundation, and hand you a written price that includes the engineering the city requires – before you commit to anything.
