Fast, Reliable Home Additions & ADU Across Hurst
Home additions and ADU construction in Hurst typically run $45,000 to $130,000 for a room addition, and $90,000 to $220,000 for a detached ADU, depending on scope. What most quotes leave out here is Hurst’s own building department rules: open a wall on a pre-1978 house and you can trigger mandatory insulation, egress window, and electrical panel upgrades before rough-in can even start. We scope those in writing up front. If you’re weighing an addition or ADU in Hurst, call (877) 610-1318 for a free estimate – no trip charge inside the county.
Why Barrett & Sons Construction Is Hurst’s Preferred Home Additions & ADU Company
We’re Home Additions & ADU contractors who work Hurst every week. Tom Barrett, our owner, publishes his name, address, and license number – look it up before you sign anything. His sons run our crews. When a homeowner near Bellaire Drive in 76053 calls about a master suite addition, the person who answers the phone knows exactly what the Hurst permitting process will require before we ever pull a tape measure. That matters in this city. Hurst’s housing stock was built between 1955 and 1978, and the moment you open a wall here, the house has to meet codes that didn’t exist when it was built. We’ve been on enough Hurst jobs to quote those upgrades correctly the first time.
Every Hurst job gets permits pulled and inspections signed. Every change order is in writing before work happens. And our 90-Day Done Right Promise is on the contract – one call brings Tom back if something isn’t right. That’s why homeowners in Hurst neighborhoods like Bellaire Park and Mayfair count us as the contractor they’d recommend to the person next door.
- Owner-operated since 1998 – Tom Barrett and his sons are on-site, not a franchise dispatching strangers to Hurst.
- Written change orders, always – an allowance that isn’t on paper is a surprise waiting for a date.
- Permits pulled and inspections signed on every eligible job – and we flag Hurst’s code triggers before you sign.
Our Home Additions & ADU Services in Hurst
ADU Design & Permitting
Detached ADUs in Hurst start with two things: what the city will allow on your lot, and what your house’s existing systems will support. We handle both. We prepare site plans, structural drawings, and the permit package for Hurst’s municipal building department, and we account for the code upgrades that older Hurst homes trigger when you tie into existing electrical and water. The permit inspector works for you, not for me – that’s why we like him. We’d rather go in with a package that passes the first time.

Garage Conversion ADU
Converting an attached or detached garage into a living unit in Hurst usually runs $30,000 to $80,000. On pre-1978 ranch homes here, a garage conversion almost always requires a new electrical panel, egress windows, and exterior wall insulation to satisfy Hurst’s building department. We scope those items in writing as part of the initial bid – not as a surprise later. We also check slab condition before we quote, because Hurst sits on expansive clay that’s been moving under these homes for 45 to 70 years.

New Detached ADU
A new detached ADU in Hurst ranges $90,000 to $220,000. Before you commit, we verify sewer and water access, because not every lot in Hurst is on city utilities – some are on septic and well, and that changes setback requirements, plumbing scope, and where the structure can sit. We handle ADU site prep and utilities, including trenching, grading, and drainage. Hurst’s flat lots and clay soils mean drainage has to be spec’d correctly from day one or you’ll fight water pooling at the foundation for years.

Junior ADU & Interior Conversion
A junior ADU (JADU) converts existing interior square footage – a den, a second living room, a finished basement area – into a self-contained living unit with its own entrance, kitchenette, and bath. On Hurst’s single-story brick ranch homes, this is often the most cost-effective path to rental income or multigenerational living, because you’re working within the existing footprint. The catch is the same one we see everywhere in Hurst: opening walls on a 1965 ranch means upgrading insulation and wiring to current code. We quote that work as part of the job, not as an add-on.

Trusted Brands We Service in Hurst
For windows and doors on Hurst additions and ADUs, we work with Simonton, Ply Gem, and PGT – brands you can look up. We don’t install mystery materials off a van. On a 76053 ranch home, new windows in an addition are the difference between a room that holds temperature in an August heat wave and one that fights the AC all summer. We keep ordering relationships with these manufacturers current so Hurst customers aren’t waiting on backordered frames when the roof’s already open. If you have a brand preference, say so at the estimate – we’ll spec it.
Common Home Additions & ADU Problems We See in Hurst Homes
- Code-triggered upgrades nobody bid. Hurst has its own municipal building department, and most homes here predate modern IRC energy and structural codes. Open a wall or touch the roof plane on a 1962 ranch, and insulation, egress windows, and electrical panel upgrades become mandatory. A cheap bid that ignores this is not cheaper – it’s just missing.
- Clay soil movement under slab-on-grade homes. Hurst sits on Blackland Prairie-adjacent clay. North Texas boom-bust moisture cycles – summer drought, then heavy fall and spring rain – make that clay shrink and swell seasonally for decades. A room addition tied to an older slab will crack at the transition if we don’t specify subfloor reinforcement and drainage as part of the scope.
- Septic and well unknowns on the lot. Not every Hurst property is on city sewer and water. If the addition or ADU assumes municipal connections and the site is actually on septic and well, the re-scope after the permit is pulled can add five figures. We verify utilities before we quote, not after.
- Undersized headers and original single-pane windows. The 1955-1978 Hurst housing stock was built to mid-century standards. Opening a wall for an addition routinely reveals non-insulated exterior walls, original aluminum-framed windows, and headers that no longer meet structural code. That’s not a surprise to us – it’s a line item.

FAQs – Home Additions & ADU in Hurst
Hurst has its own municipal building department, and you pull your permits through the city of Hurst, not Tarrant County. That matters more in Hurst than in newer suburbs because most of the housing stock predates modern IRC codes, so Hurst inspectors enforce current code on any wall you open or roof plane you touch. We package the permit application to Hurst’s specific requirements so the review doesn’t stall. Call (877) 610-1318 and we’ll tell you exactly what your job will trigger before you pay for drawings.
Yes, but the septic and well change the math. A detached ADU on septic requires additional setback distance between the new structure and the drain field, and the existing septic system may need evaluation for the added load. Well water for an ADU also needs to meet the same potable standards as the main house. We verify your utility access before we quote, and we scope any septic or well adjustments in writing up front. Call (877) 610-1318 and we’ll check your lot before you spend a dollar on plans.
In almost every pre-1978 Hurst home, yes. A garage conversion ADU adds a kitchenette, a bath, and separate circuits, and the original 100-amp panels in most of these ranch homes won’t carry the additional load under current code. Hurst’s building department will require the panel upgrade as part of the permit. We include it in the initial bid, not as a mid-job change order. Call (877) 610-1318 for an exact quote on your address.
On many Hurst lots, yes. The city is flat, and the underlying clay expands and contracts seasonally with North Texas’s drought-and-rain cycle. If we don’t spec subfloor reinforcement and positive drainage away from the new foundation, the addition cracks at the transition joint where new slab meets old slab. Proper grading, drainage, and reinforcement add cost to the bid, but skipping them adds much more to the repair later. We walk your lot before we quote so those line items are in the first number, not a surprise.
For a 1955-1978 brick ranch in Hurst, expect to set aside $8,000 to $25,000 beyond the base addition cost for code-triggered upgrades. Opening the first-floor walls for a second-story addition means current insulation requirements, egress windows where sleeping rooms are added, and almost always a new electrical panel. Undersized headers in the existing structure routinely need reinforcement before the new floor system goes on. We scope these as predictable line items, not “unexpected” findings. Call (877) 610-1318 for a written estimate that includes them from day one.
If you’re planning a home addition or ADU in Hurst, call Barrett & Sons Construction at (877) 610-1318. We’ll walk your lot, check your utility access, flag the Hurst-specific permit triggers before you sign, and hand you a written line-item quote. Senior and veteran discounts apply on every job.
