AfterFast, Reliable Home Additions & ADU Across New Territory
A home addition or ADU in New Territory typically runs $45,000-$130,000 for a room addition and $90,000-$220,000 for a new detached ADU, and the two things that shape your timeline more than anything else are the HOA architectural review and the condition of your post-tension slab. We’ve worked enough jobs in the 77487 zip code to know both cold. If you’re planning to add square footage in New Territory, call Barrett & Sons Construction at (877) 610-1318 and we’ll walk the property, check the slab, and get your HOA submittal packet moving before you spend a dime.
New Territory was built out almost entirely between the late 1980s and mid-1990s, which means every house on your street is hitting the same age milestones at the same time. Original windows, original roof decking, original post-tension slabs. We know what that means for an addition because we’ve seen it on Chestnut Bend, on Pecan Grove Drive, on homes backing up to the levee. None of it surprises us anymore. That local knowledge is the difference between a job that starts on schedule and one that sits half-finished waiting on a committee.
Why Barrett & Sons Construction Is New Territory’s Preferred Home Additions & ADU Company
Tom Barrett founded this company in 1998, and his sons run the crews. When we show up in New Territory, the name on the truck is the name on the contract, and the people swinging hammers are the ones who’ll be at the hardware store on Saturday. That matters in a master-planned community like this one, where word travels fast and a bad job follows you block by block.
We’ve earned our reputation in New Territory the slow way: pulling permits on every job, filing HOA submittals so they pass the first review, and putting every price change in writing before a single nail moves. Tom publishes his name, his address, and his license number. Ask anyone on your street, or look up the license number yourself. He wants you to.
Our crew members are background-checked and uniformed, and a live person answers the phone 24 hours a day. Not a voicemail box, not an out-of-state call center. When a New Territory homeowner calls about an addition, they talk to someone who knows what a Fort Bend County elevation certificate costs and how long the New Territory architectural review board is taking this quarter.
Our Home Additions & ADU Services in New Territory
Every New Territory addition starts with the same two gatekeepers: the HOA architectural review board and the post-tension slab under your house. We’ve built our whole process around getting both of them right the first time. Here’s what we handle in New Territory:
ADU Design & Permitting
A detached ADU in New Territory is a $90,000-$220,000 project, and the design phase is where most contractors stumble. The HOA requires exterior materials, brick color, mortar shade, roof pitch, and window styles to match the original 1990s plat standards. We prepare the full submittal packet, including color samples and elevation drawings, so the architectural review board sees exactly what your neighbors will see. We file it, we track it, and we schedule around the review window so the crew isn’t standing on your lawn waiting for a signature.
Garage Conversion ADU
Converting an attached garage into a livable ADU in New Territory runs $30,000-$80,000, and it’s usually the fastest way to add a rental unit or in-law suite without expanding the footprint. But here’s the catch: the HOA will scrutinize the front elevation. If your garage door gets replaced with a wall, the brick and mortar have to match the existing veneer, and the window style has to read as intentional, not tacked on. We’ve done enough garage conversions in New Territory to know exactly what the board approves and what gets sent back for revision.
New Detached ADU
Building a detached ADU behind a New Territory home means starting from scratch: new foundation, new utilities, new roof. The slab work matters here more than anywhere, because the Beaumont clay under your yard moves with every rain-and-drought cycle. We do a pre-pour elevation survey and soil test before we ever lay forms, so the new ADU doesn’t settle differently from the house it sits behind. Then we run the HOA packet and the Fort Bend County permit on parallel tracks so neither one stalls the other.
Junior ADU & Interior Conversion
A junior ADU, like a finished attic conversion or a sectioned-off wing with its own entrance and bath, is a smart New Territory play when the existing slab won’t support a heavy addition and the HOA wants to see zero exterior change. Interior conversions often skip the architectural review entirely, which cuts 30+ days off your timeline. We’ll tell you honestly whether your plan needs HOA sign-off or slides through with just a Fort Bend County permit.
We also handle Home Additions & ADU work of every size: second story additions, sunrooms and enclosed patios, and full room additions. If you’re not sure which route makes sense for your lot and your budget, call us and we’ll walk it with you.

Trusted Brands We Service in New Territory
When we pour a driveway apron to reach the new ADU, we use Quikrete and Oldcastle products because they hold up to Fort Bend County’s clay movement better than cheaper bag mixes. For paver patios and walkways around a new addition, we stock Techo-Bloc because the color range matches the neutral brick palettes that dominate New Territory’s original 1990s builds. You can look these brands up yourself. We don’t install mystery materials off the back of a van, and the HOA likes a named product line when they’re reviewing your submittal.
Common Home Additions & ADU Problems We See in New Territory Homes
- Skipped HOA review, stop-work notice waiting. The New Territory architectural review board takes 30+ days, and some contractors “helpfully” suggest starting the easy site work while you wait. That’s how you get a stop-work notice over brick color before the foundation is even in. We file first, then schedule.
- Post-tension slab movement at the new-to-old junction. Fort Bend County’s Beaumont and Houston Black clay shrinks in drought and swells in rain, and original 1990s slabs have been doing that dance for 30 years. Skip the pre-pour elevation survey and your new addition will crack at the seam within two seasons.
- Ground-level additions with no elevation certificate. Hurricane Harvey’s 2017 flooding hit areas immediately around New Territory hard, so Fort Bend County inspects ground-level construction with an eye for flood mitigation. Miss the elevation certificate and you’ll fail inspection, then pay a change order to regrade after rough-in is done.
- Roof tie-ins on two-story brick-veneer homes. The heavy two-story floor plans common to New Territory’s original builders don’t forgive a lazy roof junction. We see hacked-on additions where the roof line doesn’t match and water channels right into the old roof decking. Our framing crews cut the tie-in so rain flows like it was built that way in 1993.
Our crew recently tied a 450 sq ft first-floor addition into a two-story brick-veneer on Chestnut Bend, where the existing post-tension slab had drifted nearly an inch at the rear corner after decades of Beaumont clay swell-and-shrink. We filed the HOA submittal with brick and mortar color matched to the original ’90s palette, pulled the Fort Bend County permit, and had the foundation inspected and stabilized before rough-in. The inspection sign-off and architectural review landed before drywall ever went up. That’s the sequence, and it works.

What moves the number on a New Territory addition? The HOA review adds time, not dollars, but it influences material choices that do affect cost. A detached ADU with a full kitchen and bath runs higher than a junior ADU with a kitchenette. Foundation work on a slab that’s drifted badly costs more than a slab that’s held true. Every scope, every allowance, every price change arrives as a written change order before work happens. No surprise invoices at the end.

FAQs - Home Additions & ADU in New Territory
File at least 45-60 days before your target start date. The New Territory architectural review board typically takes 30+ days to respond, and first-round revisions are common because the standards are specific: brick and mortar color, roof pitch, window style, even the brand and grade of roofing shingles. We prepare the full packet and file it before we schedule the crew, so the review clock is running while we handle design, engineering, and the Fort Bend County permit. Call (877) 610-1318 and we’ll give you the current review timeline.
Detached ADUs are generally permitted in New Territory, but the HOA applies the same exterior standards to an ADU that it applies to the main house: brick and mortar color must match the original 1990s plat palette, roof materials must match or closely match the existing shingle grade, and window and door styles must be consistent with the neighborhood’s original architecture. The HOA controls exterior finishes down to brick mortar color and roofing shingle grade, and skipping that review gets stop-work notices mid-project. We include the full HOA submittal in our scope of work.
A typical New Territory addition includes a pre-pour elevation survey, a soil test, and a slab condition assessment before we design the foundation tie-in. Original 1990s post-tension slabs on Beaumont clay have usually drifted slightly, and we need to know exactly how much before we decide whether to pin the new slab, pour an isolated foundation, or remediate the existing one. If the slab needs stabilization, that’s a written change order before it happens. Call (877) 610-1318 for a free foundation assessment during your estimate.
We file it for you. The homeowner is technically the applicant on New Territory HOA forms, but we prepare the entire packet-elevation drawings, material samples, color swatches, site plan-and we submit it under your name, then track the review and answer any board questions. Most contractors hand you a form and wish you luck. We don’t. It’s your house, but it’s our job to know what the board approves.
Yes, and they do it regularly. The New Territory HOA has enforcement power over exterior work on every lot in the community, and they issue stop-work notices when construction starts without an approved architectural review. We’ve seen foundations poured and framing started, only for the board to flag a brick color mismatch and halt everything. That’s a month of standing still you can’t get back. We file before we dig, always. Call (877) 610-1318 and we’ll make sure your packet is in before your first inspection.
