AfterFast, Reliable Home Additions & ADU Across Euless
Adding square footage in Euless typically costs $45,000-$130,000 for a room addition and $90,000-$220,000 for a detached ADU. Your project will almost certainly involve one thing most contractors in North Texas never deal with: FAA height review, because Euless sits directly under DFW International Airport’s airspace. We’ve been navigating that reality since 1998. Call (877) 610-1318 and Tom or one of his sons will walk you through what your specific home actually needs.
We know the 76039 and 76040 housing stock because we’ve worked on it for decades. The 1960s brick-veneer ranches off Harwood Road, the split-levels near Westpark and South Euless, the mid-century tracts along Main Street that haven’t been touched since Nixon was in office. When you open those walls, you find what we already expect: aluminum wiring, undersized panels, framing that was borderline when it was new. That’s the job. Every scope item goes in writing before we start, and any surprise gets priced and approved on paper before a saw comes out.
Why Barrett & Sons Construction Is Euless’s Preferred Home Additions & ADU Company
We’re not a franchise. Tom Barrett started this company in 1998, and his sons run crews on most Euless jobs. When you call, a live person answers, day or night. When you have a question mid-project, you call Tom. When something isn’t right after the job is done, the 90-Day Done Right Promise means one call brings him back. That’s written on every contract, not implied in a handshake.
Euless homeowners keep calling us back for a reason. Our crews work in Bedford, Colleyville, Hurst, and Grapevine too, so we understand how the Mid-Cities market actually prices work. More important, we understand Euless specifically: the foundation patterns in Blackland Prairie clay, the FAA paperwork that applies to height increases, and the code upgrades that a permit triggers the moment an old wall comes down. Look up Tom Barrett’s name, address, and license number before you sign anything. He publishes them on purpose.
Here’s our standing offer to Euless residents: no trip charge inside the county, free second opinion on any written estimate you’ve gotten from another contractor, $40 off any repair over $200, and a permanent 10% senior and veteran discount. Those aren’t coupon tricks. They’re the terms we’ve run on since day one.
Our Home Additions & ADU Services in Euless
ADU Design & Permitting
An accessory dwelling unit in Euless starts with a question most contractors in Grand Prairie never ask: does this project trigger FAA Form 7460? If your ADU adds height, even a modest second-story unit near the Highway 183/121 corridor, the answer is usually yes. We handle the FAA filing, the city permit package, and the design work together, so you’re not stuck coordinating three separate documents. A permitted ADU in Euless runs $90,000-$220,000 depending on size, finishes, and whether it’s attached or detached.
Garage Conversion ADU
Euless has thousands of two-car garages attached to 1960s and 1970s homes. We’ve converted enough of them to know what’s behind the drywall before we open it: original single-pane windows, undersized electrical, and sometimes slab heave from the Blackland Prairie clay. A garage conversion ADU in Euless runs $30,000-$80,000. The permitting process involves separate electrical and mechanical reviews, and we coordinate those because we’ve done them here for years.
New Detached ADU
For homeowners with a usable back lot in 76040 or 76039, a detached ADU gives you rental income or a place for family without squeezing the main house. But the foundation has to be right first, because Euless clay cycles between wet and dry in a way that will crack an undersized slab within a year or two. We design for the soil you actually have, not the soil a generic plan assumes. Expect $90,000-$220,000 for a new detached ADU, and plan for a foundation review before framing.
Junior ADU & Interior Conversion
A junior ADU inside an existing Euless home is the lowest-cost way to create a separate living space: convert a finished basement, enclose a sunroom, or divide a large split-level lower floor into its own unit with a kitchenette and private entrance. Interior conversions fall under our broader Home Additions & ADU scope. The main variable is whether your existing plumbing and electrical can support the second kitchen and laundry hookups, and usually, a 60-amp subpanel won’t. We write that allowance in up front.

Trusted Brands We Service in Euless
We install brands our Euless customers can look up before we set foot on the property. For kitchens, KraftMaid cabinetry and Cambria countertops. For roofs, GAF and CertainTeed. For windows and doors, Andersen and Marvin. For hardscapes, Belgard and Techo-Bloc. In bathrooms, we regularly spec Schluter waterproofing systems and Grohe fixtures. We don’t show up with mystery brand off a van and hope you won’t ask. Every material gets named on the written scope of work, and if an allowance changes, you sign a change order before the order goes in.
Common Home Additions & ADU Problems We See in Euless Homes
- Slab heave from Blackland Prairie clay. Spring rains swell the soil and summer drought shrinks it, and that cycle cracks slabs and piers on Euless homes built before modern foundation standards. Any addition we frame starts with a foundation inspection, because framing over a moving slab is wasted work.
- FAA height review surprises. A second-story addition on a 1960s split-level near Highway 183/121 can trigger FAA Form 7460 and Part 77 obstruction review. Contractors who don’t work in the DFW airspace shadow often find out at rough-in, and the job stalls.
- Undersized electrical panels. 100-amp service was standard in 1970s Euless tract homes. Add a second kitchen, laundry, or HVAC zone for an ADU, and you’ll need a panel upgrade. We write that into the scope before we open the wall, not after.
- Termite and moisture damage in load-bearing framing. Older Euless homes, especially brick-veneer ranches on pier-and-beam foundations, hide damaged studs and sill plates. Opening an exterior wall for an addition often reveals framing that has to be replaced before an inspector will pass it.
Pricing for Home Additions & ADU in Euless, TX
Every addition in Euless is priced from a written scope, not a phone estimate. Here’s what you should expect based on the work we’ve done across the Mid-Cities:
| Project Type | Typical Euless Range |
|---|---|
| Home Addition (room or suite) | $45,000-$130,000 |
| ADU Construction (detached or attached) | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
The single biggest price driver in Euless is what the permit triggers once walls are open. A code upgrade for electrical, a structural repair that wasn’t visible before demo, an FAA filing you didn’t know you needed. We handle those with allowances written into the contract and change orders issued before work proceeds. Call (877) 610-1318 for a free, written estimate that accounts for the actual condition of your home, not a generic square-foot multiplier.

FAQs - Home Additions & ADU in Euless
Yes, possibly. Euless sits under DFW International Airport’s airspace influence zones, and FAA Part 77 obstruction standards apply to structures based on height and proximity to runways, not just the number of stories. A tall one-story ADU with a steep roofline near the Highway 183/121 corridor can trigger Form 7460 review. A modest single-story addition on a flat lot deeper into 76040 often doesn’t. We determine this during the design phase, before permits are filed, so you’re not surprised at rough-in. Call (877) 610-1318 for a site-specific answer.
We inspect the existing slab or pier-and-beam foundation first, before any framing. Euless clay swells with spring rain and shrinks in summer drought, and if your home has already moved, the addition will move with it unless the foundation is addressed first. We write any required piers, root barriers, or reinforced footings into the scope of work as a line item. The inspector signs off on it before framing starts, and the cost is agreed in writing before we dig. Call (877) 610-1318 if you want a foundation read before you commit.
You get a written change order before we touch anything else. That’s our rule on every job in Euless: the allowance that isn’t on paper is a surprise waiting for a date. If we open the attic for a second-story addition and find a 100-amp panel that can’t carry the new load, or load-bearing studs with termite damage, we price the repair in writing, you approve it, and only then do we proceed. You’re never billed for something we didn’t show you first. That’s the Barrett & Sons way, and it’s on every contract.
Yes. Any garage conversion ADU in Euless triggers a separate electrical permit because you’re adding a new dwelling unit, and that almost always means a panel upgrade on a 1960s or 1970s home built with 100-amp service and aluminum wiring. The mechanical permit for HVAC and the plumbing permit for a bath or kitchenette are also separate. We handle all three, plus the FAA filing if the conversion adds height. The cost is all in the range we quoted you at the estimate, not something that appears at the end. Call (877) 610-1318 for exact numbers on your garage.
Probably not. Split-level homes built in the 1960s and 1970s already have a raised roofline, and adding a second story increases height enough that Euless’s south-approach airspace rules typically require FAA Form 7460 filing and Part 77 compliance. Contractors in Grand Prairie or Fort Worth rarely deal with this, but we file it as a standard part of our permitting package on height-adding Euless projects. You get the paperwork handled, the permit pulled, and the inspection signed off before framing. Call (877) 610-1318 to have us check your specific lot and roofline.
