AfterFast, Reliable Home Additions & ADU Across New Territory
Home additions and ADU construction in New Territory typically run $45,000-$130,000, and most projects take 90-180 days from HOA submittal to final inspection. If you’re planning a room addition, second-story build, or detached ADU in the 77487 ZIP code, the single biggest schedule factor isn’t the framing crew or the materials. It’s the HOA architectural review board, and we’ll get into exactly how that works below. Barrett & Sons Construction serves New Territory with crews who know Fort Bend County’s permitting process and this community’s design standards cold. Call (877) 610-1318 for a free estimate, and we’ll walk you through the entire sequence before anything gets signed.
Why Barrett & Sons Construction Is New Territory’s Preferred Home Additions & ADU Company
We’ve built additions and ADUs in New Territory long enough to know that this community doesn’t tolerate sloppy exterior detailing. The HOA here enforces brick mortar color, shingle grade, roofline profiles, and even paint tones. A contractor who treats that review as a formality ends up with a stop-work notice taped to a half-framed wall. We file the submittal packet correctly the first time, and we schedule around the review window so your materials aren’t sitting on the driveway while a committee meets.
Tom Barrett founded this company in 1998, and his sons run the crews. When we’re on a job near the New Territory Sugar Land border, you’ll see the same faces every morning, not a rotating cast of subcontractors. Our Home Additions & ADU team handles everything from first sketch to final inspection, including the architectural review submission, the Fort Bend County permit, and the post-tension slab assessment every addition here needs. If a homeowner in New Territory has a concern mid-project, they call one number and get a live person around the clock.
We carry the 90-Day Done Right Promise in writing on every contract. Not buried in an appendix. If something’s not right after we finish, one call brings Tom back. That’s the standard we’ve held across New Territory and every surrounding community for over 29 years.
Our Home Additions & ADU Services in New Territory
ADU Design & Permitting
The HOA in New Territory requires architectural review before Fort Bend County will issue a building permit for a detached ADU. That review packet includes elevation drawings, material samples, and a site plan showing setbacks and drainage. We prepare all of it, submit it, and track it through the committee calendar. Most New Territory ADUs clear architectural review in 30-45 days if the packet is complete. Ours are.
Garage Conversion ADU
Converting an attached garage in New Territory is often the fastest path to a rentable unit or in-law suite, $30,000-$80,000 depending on plumbing rough-ins and kitchenette finishes. The catch here is that the HOA has restrictions on changing the front elevation, so we typically preserve the original garage door opening with a permanent wall set back behind it. That keeps the streetscape intact and keeps the review board happy.
New Detached ADU
A detached ADU in New Territory runs $90,000-$220,000. That range reflects the foundation work this soil demands. Beaumont clay under New Territory moves enough during drought cycles that we specify deeper piers or thickened-edge slabs for any structure independent of the main house. We also grade the site to move water away from both foundations, a detail Fort Bend County inspectors check closely since Harvey.
Junior ADU & Interior Conversion
Junior ADUs and interior conversions keep everything inside the existing footprint, which sidesteps most exterior review triggers. Think of a first-floor study turned into a small apartment with its own entrance through a rear door. The HOA still wants to see the door detail and any window changes, but the review is usually faster. These projects start around $45,000 and go up based on the kitchenette and bath scope.

Trusted Brands We Service in New Territory
When your addition or ADU calls for pavers, concrete, or exterior hardscape around the new structure, we use brands you can actually look up. Techo-Bloc and Cambridge Pavers for patios and walkways tied into the addition, Quikrete and Oldcastle products for foundation and site work. We don’t put mystery materials off the back of a van onto your property, and we don’t ask you to accept whatever the supply house had on clearance. Your addition should look like it grew with the house, not like it was bolted on.
Common Home Additions & ADU Problems We See in New Territory Homes
- Stop-work notices from the HOA. This is the big one in New Territory. Skipping architectural review, or submitting a packet with the wrong brick color or shingle sample, gets a project halted mid-framing. We’ve been called to fix these for other contractors, and it’s always slower and more expensive than doing the review right the first time.
- Post-tension slab movement at the tie-in. New Territory’s Beaumont clay shrinks and swells with wet and dry seasons. When you tie a new foundation to a 30-year-old post-tension slab without assessing movement, you get cracks at the seam within the first year. We order the assessment before we pour.
- Original 1990s systems failing mid-project. Most New Territory homes were built in a single wave between the late 1980s and mid-1990s. When we open walls for an addition, we frequently find original wiring, original plumbing, and original framing techniques that don’t meet current code. We handle those corrections as written change orders, never as surprises at the end.
- Grading and drainage issues on ground-level additions. Portions of Fort Bend County around New Territory flooded during Harvey. Any ground-level addition or ADU here needs proper grading, and often an elevation certificate, before the county signs off. We build that into the scope from day one.
Pricing for Home Additions & ADU in New Territory, TX
Here are the honest ranges for this market, based on what we actually bid and build in New Territory:
| Project Type | Price Range |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
What moves the number within those ranges: square footage, whether you’re adding a bath or kitchenette, foundation depth required by Beaumont clay conditions, and the HOA’s finish requirements. A second-story addition on a two-story 1990s brick-veneer home lands at the higher end because of structural tie-in work and brick matching. A simpler interior conversion lands at the lower end. Every price change comes as a written change order before work proceeds. Call (877) 610-1318 and we’ll put a written line-item quote in your hands.

FAQs - Home Additions & ADU in New Territory
Yes, the New Territory HOA requires a separate architectural review application for a detached ADU, and the county will not issue the building permit until the HOA approves it. You need both. We file the HOA submittal packet first, get the approval letter, then take that letter to Fort Bend County with the permit application. Call (877) 610-1318 and we’ll handle both tracks from the start.
The Beaumont and Houston Black clay under New Territory shrinks during dry spells and swells after rain, which moves the post-tension slab under the existing house. Any new foundation has to accommodate that movement or you’ll get cracks at the seam within a season or two. We assess the existing slab, design the new foundation for the soil conditions, and include that work in the written quote before construction starts.
Work stops immediately, and nothing moves forward until the architectural review board signs off. If the unapproved work doesn’t match the HOA’s material and color standards, it has to come down or get reskinned at your expense. We’ve taken over several of these jobs in New Territory. The fastest path out is filing the correct submittal packet, scheduling the review, and preparing a remediation plan for anything already built. Call (877) 610-1318 and we’ll give you a straight assessment of what it’ll take.
Plan on an extra 30-45 days beyond the county permit timeline. The HOA review board meets on a set calendar, and incomplete packets get bounced to the next meeting. A complete packet from day one keeps you in the first available review slot. We build that window into the schedule up front so your crew isn’t idle and your materials aren’t sitting exposed.
Attached garage conversions are permitted in New Territory, but the HOA generally requires that the front elevation keep a garage-door-compatible appearance, which often means a permanent wall set behind the original door location. Interior layout and egress are governed by Fort Bend County code. We’ve converted garages across New Territory and we know which design decisions will get through review. Call (877) 610-1318 for a free estimate and a written plan that accounts for HOA requirements before anything is built.
