Adding an ADU in Hurst usually costs between $180,000 and $320,000 for a detached backyard unit, before site work like foundation corrections or utility trenching. That’s a real number, not a teaser. We’re Sutton ADU Fort Worth, and we handle the full build from soils test to final inspection across Hurst, including neighborhoods like Mayfair, Prestwick, and the streets off Hurstview Drive. Call (682) 255-2399 to get a written price before any work starts.
What makes Hurst different is the dirt. Expansive clay moves. Slab-on-grade homes from the 1950s through 1980s react to that movement. Any ADU project here has to account for it honestly, from the first inspection to the foundation design. We know that because we’ve opened enough Hurst walls and poured enough Hurst slabs to see what happens when someone skips that step.
Why Sutton ADU Fort Worth Is Hurst’s Preferred ADU Builders Company
Hurst homeowners call us because we name who’s coming before they arrive. Every technician is background-checked, identity-verified, and photo-badged under the Threshold Standard. You get a name and a photo sent to your phone before our crew knocks. That matters when you’re letting construction workers onto your property for months, not hours.
Our reviews from Hurst jobs mention the same thing repeatedly: the written price held, the crew was vetted, and the change orders were explained in plain English. We don’t trade on a nebulous “trust us” pitch. We prove it. The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion. If something fails, we make it right, including a free second visit. No haggling.
Miles Hartwell leads our team. He’s the name on the contract and the voice on the phone. When a Hurst homeowner calls with a question about a slab slope or a panel upgrade, they talk to a person who knows the property, not a call center.
Backyard ADU in Hurst
A backyard ADU in Hurst is a detached living unit built on open side or rear yard space, and most lots here have enough room for one. With many homes sitting on 0.2 to 0.5 acres, a studio or one-bedroom ADU fits where a garage conversion can’t. A new detached build in Hurst typically runs $200,000 to $320,000 depending on size, finishes, and how much foundation prep the clay soil demands.
Foundation and Soil First
Before a single wall goes up, we check the soil. Hurst’s expansive clay expands when wet and shrinks in drought. That cyclical movement cracks slabs. A new ADU foundation has to be engineered for that movement, usually with deeper piers or a suspended slab, which adds upfront cost but prevents drywall cracks and door misalignment two years later.
We also look at the existing yard’s drainage. Water pooling against a new ADU slab accelerates clay swelling. French drains or regrading often go into the written scope before excavation starts, not as a surprise invoice later.
Prefab vs. Custom Builds
Some Hurst homeowners want a factory-built ADU. We install prefab and modular systems from Plant Prefab and Mighty Buildings where the lot access supports crane delivery. Others prefer a custom frame build to match the existing home’s brick veneer. Both routes work. The choice usually comes down to lot dimensions, tree coverage, and how quickly you want the unit weather-tight.
ADU Construction in Hurst
ADU construction in Hurst means either building from the ground up or reworking an existing structure into habitable space. That includes garage conversions, interior carve-outs, and detached ground-up builds. A garage conversion here typically runs $80,000 to $160,000, while a ground-up backyard ADU pushes into the $200,000 to $320,000 range once site work is included.
Garage Conversions and Local Setbacks
Hurst’s older neighborhoods have garages that were built close to or on the property line decades ago. Converting them into an ADU triggers a setback review. The required gap between the structure and the property line didn’t exist as a concern when the garage went up. Today, habitable space must meet current code. We’ve worked with homeowners on variances and creative compliance solutions that keep the project moving.
Panel Upgrades and Hidden Wiring
Older Hurst homes often have 100-amp electrical panels. An ADU needs its own subpanel, breakers, and often a service upgrade to 200 amps. If the panel is full when the permit gets pulled, the upgrade becomes mandatory. We write allowances into the contract for exactly this. The price is set before we open the wall, and any change still needs a signed approval.
Trusted Brands We Service in Hurst
We’re experienced with several ADU product lines, including Boxabl, Mighty Buildings, and Plant Prefab. For Hurst customers, that matters in practical terms: we know which units fit through standard side-yard access, which foundation specs each brand requires, and what lead times to expect. We also work with Tuff Shed structures for studio ADUs and James Hardie exterior systems for cladding that handles Texas heat without warping. Local parts availability means faster turnaround when a panel, window, or trim piece needs replacing mid-build. Our ADU Builders team has direct relationships with these manufacturers, not third-party distributors.
Common ADU Builders Problems We See in Hurst Homes
- Sloped garage slabs: In 1950s and 1960s Hurst homes, garage floors were poured with a deliberate slope toward the door for drainage. That slope violates the flatness standard for living space. We inspect for this before quoting finish flooring, not after framing goes up.
- Full electrical panels: A 100-amp panel with no spare breakers is routine in Hurst’s older stock. Connecting an ADU to that panel requires a service upgrade. We test breaker capacity during the first inspection so the upgrade appears in the original written price.
- Rotted sill plates on slab homes: Years of slab moisture wicking into untreated framing rots the wood at the base of walls. In garage conversions, we routinely find sill plates that need sistering or replacement before insulation. It’s a Hurst-specific failure mode tied directly to slab-on-grade construction.
- Expansive clay movement: Foundations that have shifted over decades may have hairline cracks that predate your ADU project. Confirming whether those cracks are active or dormant determines whether we need deeper piers or a standard slab. Skipping that question is how ADUs in Hurst fail within two years.
Pricing for ADU Builders in Hurst, TX
Most detached ADUs in Hurst run $200,000 to $320,000 before considering site-specific foundation work. Garage conversions fall between $80,000 and $160,000. A junior ADU carved from an existing primary structure can cost $60,000 to $120,000. What moves the number is what’s hidden: soil test results, panel capacity, slab flatness, and setback variances.

FAQs About ADU Builders in Hurst
A setback is the minimal distance between a building and the property line, and Hurst enforces it when you change a garage from vehicle storage to living space. Garages built before Hurst’s current zoning code often sit too close to the side or rear lot line and must go through a variance process. We handle that paperwork and present each variance option with its cost before you commit. Call (682) 255-2399 and we’ll pull up your lot’s setback status in our first conversation.
Set aside $8,000 to $15,000 for surprises in a 1960s Hurst home; common finds include 100-amp panels with no spare capacity, aluminum wiring that must be replaced on the circuits we touch, and cast-iron drain lines that crack during excavation. We put those allowances into the contract as line items, so the money is already set aside before we find the problem. If we don’t use the allowance, you don’t pay it. Call (682) 255-2399 for a written price that includes this buffer.
Yes, for a detached ADU on a slab-on-grade lot, Hurst’s building department typically requires a geotechnical soils report to confirm the expansive clay’s load-bearing capacity and movement potential. The city’s permitting process uses that report to approve the foundation design. We arrange the test, usually costing between $2,000 and $4,000, and build the foundation to the report’s specs. Call (682) 255-2399 to schedule your free estimate and we’ll start that paperwork early.
No, you cannot keep a functioning garage door as the front wall of a legal ADU in Hurst, because habitable space requires an insulated, sealed wall that meets energy and safety code. You can preserve the garage door’s exterior appearance with a false wall behind it, but the door itself must be removed or permanently sealed. We’ve done this exact detail on several Hurst conversions. Call (682) 255-2399 and we’ll show you examples.
Our approach is to open the wall far enough to find the true source of moisture, write a change order that fixes the waterproofing at the root cause, and get your signed approval before closing the wall back up. We do not bury a known leak behind drywall. In Hurst, slab moisture wicking through concrete often travels up walls that were never sealed, so the fix usually means installing a vapor barrier and repairing the sill framing, not just caulking the surface. Call (682) 255-2399 for an inspection quote that includes a moisture assessment.
