AfterFast, Reliable Home Additions & ADU Across Pecan Grove
Home additions and ADU construction in Pecan Grove typically run between $45,000 and $220,000 depending on scope, and the single biggest variable here isn’t materials or labor. If you’re also considering Bathroom Remodeling in Pecan Grove, we can bundle that into the scope. It’s the two-agency permit path. Pecan Grove sits unincorporated in Fort Bend County, which means every addition and ADU needs county approval plus Fort Bend County Drainage District sign-off on grading and detention before a single footing gets poured. We’ve been navigating that process for years, and we’ve learned exactly where projects stall if you don’t plan for it from day one. Call (877) 610-1318 and we’ll walk you through what your specific addition will require in Pecan Grove, in plain English, before you spend a dime.
Why Barrett & Sons Construction Is Pecan Grove’s Preferred Home Additions & ADU Company
Tom Barrett put his name on this company in 1998, and his sons run the crews that work in Pecan Grove. That’s not a tagline. When you call, a live person answers, 24 hours a day, and when Tom’s crew shows up to your house in the Plantation, you’re getting the same people who will stand behind the work three months, three years, or ten years later. We publish Tom’s name, address, and license number. Look us up before you sign anything. Ask anyone on your street, or look up the license number yourself.
Pecan Grove homeowners have a specific frustration with big national remodelers: the quote changes, the crew changes, and the person who sold the job disappears. We’ve picked up more than a few jobs after a national outfit handed a Pecan Grove homeowner a bill that didn’t match the handshake. Our fix is simple. Every scope, every allowance, every price change arrives as a written change order before work happens. No surprise invoices at the end. And every job carries the 90-Day Done Right Promise, written on the contract. If it’s not done right, Tom comes back and makes it right. One call.
Our Home Additions & ADU Services in Pecan Grove
ADU Design & Permitting
This is where Pecan Grove projects either start clean or start wrong. An ADU in Pecan Grove means Fort Bend County building permit review and Drainage District sign-off on detention and grading. We scope the permit path before we scope the build. That includes base flood elevation compliance if your lot sits in the Brazos River floodplain, which much of Pecan Grove does. We’ve shepherded detached ADUs through this exact dual-agency process, and we’ll tell you at the bid stage whether your lot’s impervious-cover limits will allow the footprint you want.
Garage Conversion ADU
A garage conversion in Pecan Grove is often the smartest dollar-per-square-foot move available, especially on original slab homes that flooded during Harvey. Before we touch a wall, we check whether your existing slab meets current FEMA Advisory Base Flood Elevation standards. If it doesn’t, the conversion may need to be scoped as a flood-resistant retrofit, not just a finish-out. We’ve done these conversions on both original 1980s slabs and post-Harvey elevated rebuilds in the Plantation, and the scoping difference between the two is substantial. We’ll show you exactly which situation you’re in before you commit.
New Detached ADU
A new detached ADU in Pecan Grove gives you a clean foundation, which avoids some of the slab-movement headaches that come with attaching to an original 1980s home on Beaumont clay. But it also triggers Fort Bend County’s impervious-cover rules harder than any other project type. The county measures your lot’s total impervious surface, and the Drainage District will stop the job if your new concrete pad pushes you over the runoff threshold. We run those calculations before we draw the plans, so you don’t get a stop-work order after the pad is poured.
Junior ADU & Interior Conversion
A junior ADU, usually an interior conversion of an existing bedroom, den, or bonus room, is the lightest-touch way to add rental income or multi-generational space in Pecan Grove. Because you’re working within the existing building envelope, impervious-cover limits rarely come into play, and the permit path is often simpler. But “simpler” in unincorporated Fort Bend County still means county review, and if your home sits in the floodplain, you’ll want a professional eye on flood-resistant finishes and mechanical placement before you start cutting walls.

Trusted Brands We Service in Pecan Grove
When we build additions and ADUs in Pecan Grove, we install materials you can look up, not mystery brands off a van. For windows and exterior doors on Pecan Grove additions, we regularly install Simonton, Ply Gem, and PGT impact-rated products. PGT’s impact windows matter here, given what Harvey did to this community. These are the brands that hold up to Fort Bend County’s wind and flood requirements, and we keep our supply relationships tight so Pecan Grove projects don’t stall waiting on a window order. If you want Andersen or Marvin elsewhere on the house, we handle those too, but for Pecan Grove additions, these coastal-grade brands earn their keep.
Common Home Additions & ADU Problems We See in Pecan Grove Homes
- Post-Harvey elevation mismatches. We regularly see additions scoped off an original slab without accounting for current FEMA ABFE standards. The new roofline ends up below the required flood protection level, and the county inspector flags it. We scope elevation from the first site visit.
- Beaumont clay foundation movement. Pecan Grove’s expansive soils shrink and swell with Houston’s wet-dry cycles. We’ve opened walls on 1980s brick-veneer slab homes and found cracks that mean the addition’s load path needs engineered reinforcement, not just lumber. We bring in a structural engineer when the slab tells us to.
- Drainage District stop-work orders on detached ADUs. This is the mistake we see contractors new to Pecan Grove make most. They pour the pad, then the Drainage District flags the lot for exceeding impervious-cover limits, and the job freezes while detention calculations get redone. We submit those calculations before the concrete truck shows up.
- HOA architectural review surprises. Pecan Grove Plantation has architectural rules that govern setbacks, rooflines, and exterior finishes on additions and ADUs. A county permit doesn’t override the HOA. We’ve handled enough Pecan Grove projects to know which board questions come up early and address them in the design phase, not after framing starts.

The Dual-Permit Reality in Pecan Grove
Here’s the thing that generic home addition content never tells you, and it’s the single biggest reason Pecan Grove projects stall. Unincorporated Fort Bend County requires that any home addition or ADU in Pecan Grove’s floodplain obtain both a county building permit and Fort Bend County Drainage District sign-off on detention and grading. There is no city hall to walk into. Your submittal goes to the county, and then the Drainage District reviews your grading plan, detention calculations, and impervious-cover impact before you get clearance to break ground. In neighboring incorporated cities like Richmond or Sugar Land, it’s a single-desk process. In Pecan Grove, it’s two agencies, and if your contractor doesn’t sequence both from the bid stage, you’ll find out the hard way, with a demo crew idle and a rough-in date slipping by weeks. We scope this path on every Pecan Grove addition before we write the first number.
We recently completed a second-story addition on a 1990s brick-veneer slab home in the core Pecan Grove Plantation subdivision. The homeowner wanted to replace builder-grade finishes and add a primary suite, but the original slab showed telltale signs of Beaumont clay movement. Our crew worked within the Fort Bend County permit process, submitted revised detention calculations to the Drainage District, and installed a load-bearing steel beam to carry the new floor system. Then we tied the addition into the existing roofline with a change order for upgraded hurricane clips before final inspection sign-off. That’s the kind of hands-on experience you want from your Pecan Grove Roofing contractor. That’s the kind of project that teaches you where Pecan Grove additions actually live and where they die.

FAQs - Home Additions & ADU in Pecan Grove
Yes. In unincorporated Pecan Grove, a home addition needs a Fort Bend County building permit plus separate sign-off from the Fort Bend County Drainage District on detention and grading plans. The Drainage District review focuses on your lot’s impervious-cover limits and stormwater runoff, and it can add weeks to your timeline if it wasn’t sequenced from the start. We submit both agency packages in parallel on day one. Call (877) 610-1318 and we’ll tell you exactly what your addition triggers before you commit to anything.
Yes, but the scoping is different from a garage conversion on an elevated home. If your original slab sits below the current FEMA Advisory Base Flood Elevation, the conversion needs flood-resistant materials, elevated mechanical placement, and potentially flood vents depending on the county’s current requirements. We’ve converted garages on both original 1980s slabs and post-Harvey elevated rebuilds throughout Pecan Grove, and the difference in cost and scope is real. We’ll show you which category you’re in and price it honestly.
Often yes. Pecan Grove’s Beaumont clay soils are highly expansive, and original slab-on-grade homes from the 1980s and early 1990s frequently show movement. Before we draw a second-story addition, we assess the slab and bring in a structural engineer when the signs are there. Some homes only need localized reinforcement; others need deeper work. We won’t know until we look, but we’ll tell you the truth, and it’ll be in the written scope before any framing starts.
Pecan Grove Plantation has architectural review requirements for detached structures, covering setbacks, height, roofline, and exterior finish compatibility. A county permit doesn’t satisfy the HOA, and HOA denial can kill a project that already cleared the county and the Drainage District. We’ve worked with the Pecan Grove Plantation architectural committee on multiple ADU projects, and we submit HOA packets alongside the county and Drainage District applications so you’re not left holding an approved permit for a structure the HOA won’t allow.
A realistic draw schedule accounts for the dual-permit wait. On a typical Detached ADU in Pecan Grove, expect the first draw at contract signing and permit submittal, a second draw at permit approval and foundation start, a third at framing and rough-in inspection, and the final draw at final inspection and occupancy sign-off. The two-agency path means the gap between submittal and approval can run longer than in incorporated cities, so don’t let a contractor front-load the schedule and ask for the second draw before the Drainage District sign-off lands. Ours is written into the contract, and every one of our Home Additions & ADU projects carries the 90-Day Done Right Promise. Call (877) 610-1318 for an exact draw schedule on your project.
