Why Barrett & Sons Construction Is Irving’s Preferred Home Additions & ADU Company

Tom Barrett founded this company in 1998, and his sons run crews on-site most days. That is not marketing language; it is how we have worked for over 29 years. When an Irving homeowner calls us about a second-story addition near MacArthur High School or a garage conversion in the 75062 ZIP, the person who answers the phone can actually talk about your street, your setback concerns, and what the city will ask for during plan review. We publish Tom’s name, license number, and office location. Look it up before you sign anything.

Irving homeowners have dealt with national outfits that quote one price over the phone and hand over a different bill at the door. We don’t work that way. Every scope, every allowance, every price change arrives as a written change order before work proceeds. The permit inspector works for you, not for us, which is why we pull permits and pass inspections on every eligible job. Our Home Additions & ADU work across Irving comes with the 90-Day Done Right Promise written on every contract: if it isn’t done right, one call brings Tom back.

We stock materials locally and schedule crews who know Irving’s permitting counter, its older slab-on-grade housing stock, and the FAA notification quirks near Las Colinas that can wreck an amateur schedule. That local knowledge saves you weeks and avoids surprise change orders. If something goes wrong, we live close enough to come back, and we want to hear about it.

Our Home Additions & ADU Services in Irving

ADU Design & Permitting

Detached ADUs in Irving’s western residential ZIPs of 75061 and 75062 often trigger setbacks, utility easements, and sometimes FAA 7460-1 obstruction reviews if the structure sits within DFW Airport approach paths along the northern corridor near SH-114. We handle the design, the city submittal, the engineering, and the inspections in one line item. If you want to avoid a three-month permit stall, get the design right the first time. Most Irving ADU design and permitting engagements run inside the larger $90,000-$220,000 project budget.

Garage Conversion ADU

Irving’s west-side neighborhoods from the 1950s through 1970s are full of attached and detached garages that no longer fit modern vehicles. A garage conversion ADU in Irving typically runs $30,000-$80,000, and the final price depends heavily on whether the slab needs leveling, whether the existing electrical panel can carry the new load, and whether the garage sits close enough to a sewer lateral to avoid a costly line extension. We walk every Irving conversion with a written site report before quoting.

New Detached ADU

New detached ADUs in Irving generally run at the higher end of our $90,000-$220,000 range because they are ground-up builds: foundation, framing, roofing, HVAC, plumbing, and electrical. Even an ADU with Quikrete-based footings and Techo-Bloc hardscape tie-ins needs a soils report if the lot sits on Blackland Prairie clay. We order the report, read it, and build on it. We don’t guess.

Junior ADU & Interior Conversion

A junior ADU carved from an existing Irving home, often a primary bedroom suite with its own exterior entrance, is the most budget-friendly path. These commonly start around $45,000 and rise from there depending on whether you are adding a kitchenette, a second entrance, or sound isolation. In Irving’s older brick veneer homes near Nimitz High School, we often find hidden moisture in shared walls that changes the scope. We document it in writing before the first nail moves.

For homeowners who also want to refresh the main house while we are on-site, we handle Kitchen Remodeling in Irving and Bathroom Remodeling in Irving. Doing both at once sometimes lowers per-square-foot costs on shared walls, plumbing runs, and permitting fees.

Trusted Brands We Service in Irving

We carry materials Irving homeowners can look up, not mystery brands off a van. For exterior hardscape tie-ins on ADU builds and patio additions, we install Techo-Bloc and Cambridge Pavers products. For site prep concrete and paver bases, we use Quikrete. If you are comparing quotes, ask your contractor which named brands they are installing and verify them online. If they won’t tell you, that is your answer.

Common Home Additions & ADU Problems We See in Irving Homes

• Slab movement from Blackland Prairie clay. Irving sits on highly expansive montmorillonite clay that shrinks in the dry summer and heaves after fall rain. Additions and ADUs need soil moisture stabilization during site prep or you’ll get warranty callbacks and cracked veneer within two years.
• FAA notification surprises near Las Colinas. If your addition sits in the northern Irving corridor near the Las Colinas Urban Center along SH-114, your vertical build may trigger an FAA 7460-1 obstruction study. Local GCs who do not flag this early routinely blow their schedules by weeks.
• Undersized electrical panels on 1960s homes. Many west Irving tract homes still run original 100-amp panels. A true ADU with a kitchenette and laundry can exceed that load quickly. We include panel assessment in every Irving site visit and put any needed upgrade in the first written proposal, not a surprise change order.
• Pier-and-beam rot on older west Irving homes. Some 1950s and 1960s homes in the 75062 ZIP sit on pier-and-beam foundations that have never been re-inspected. When we tie an addition into one of these, we photograph and document any joist or sill damage before framing starts so you know exactly what you’re paying for.
