AfterFast, Reliable Home Additions & ADU Across Pecan Grove
Home additions and ADU construction in Pecan Grove typically run $45,000 to $130,000 for a room addition, and $90,000 to $220,000 for a full detached ADU. Most projects here take three to six months from permit submittal to final inspection, and the biggest variable is how Fort Bend County handles your elevation and drainage requirements. That’s where local experience saves you from surprises. Barrett & Sons Construction has built and remodeled homes across Pecan Grove’s Plantation neighborhoods long enough to know exactly what the county will ask for before you spend a dime. Call Tom Barrett at (877) 610-1318 and we’ll walk your property and give you a straight answer.
Why Barrett & Sons Construction Is Pecan Grove’s Preferred Home Additions & ADU Company
Pecan Grove homeowners tend to ask the same question first: will you actually be on the job, or will somebody I’ve never met run it? Tom Barrett is on-site most days, and his sons run the crews. That’s been true since 1998, and it’s the reason neighbors on Plantation Drive and in the Fairways sections keep passing our name along. You can look up Tom’s license number, his address, and his name before you sign the contract. We’d rather you did.
We pull permits and pass inspections on every eligible job, which matters more in Pecan Grove than in most places because there’s no city hall to answer to. Everything runs through Fort Bend County, and often the Drainage District signs off on grading and detention plans separately. That two-agency path can add weeks if your contractor isn’t ready for it. We are. And every price change comes to you as a written change order before work proceeds, so the number you approve is the number you pay.
Our Home Additions & ADU Services in Pecan Grove
ADU Design & Permitting
Adding an ADU in Pecan Grove means starting with the county’s elevation rules and the Brazos River floodplain. An ADU that is habitable space must meet current FEMA Advisory Base Flood Elevation standards in most cases, and Fort Bend County’s Drainage District will want to see detention and grading plans that account for added impervious cover. We design and permit the structure, handle the county submittal, and get the drainage sign-off so your project doesn’t stall at the county’s desk. Every scope, every allowance, every elevation decision arrives in writing before we submit anything.
Garage Conversion ADU
The original Pecan Grove Plantation homes that went up in the 1980s and early 1990s often have attached garages that convert cleanly into a one-bedroom or studio ADU. But slab-on-grade conversions here carry a specific risk: expansive Beaumont clay moves seasonally, and cutting a new doorway through an exterior wall can expose settlement issues that were invisible before demo. We scope for that from the first walkthrough. A garage conversion in Pecan Grove typically runs $30,000 to $80,000 depending on whether the county requires elevation or drainage upgrades.
New Detached ADU
A new detached ADU in Pecan Grove is a bigger undertaking because of the foundation work. Clay soil shrink-swell and the Brazos River flood cycle mean the slab or pier design has to be engineered for both movement and potential inundation, not just one or the other. That’s exactly what separates a barndominium-style structure that lasts three decades from one that starts showing cracks in five. We build detached ADUs from $90,000 to $220,000, with fixed pricing and no surprise change orders at the end.
Junior ADU & Interior Conversion
Some Pecan Grove homeowners don’t need a separate building. A junior ADU, typically a converted bedroom with its own exterior entrance and a small kitchenette, can add rental income or space for an aging parent without changing the home’s footprint. The key constraint is often the existing floor plan in the 80s-era brick-veneer homes, where load-bearing walls run long and plumbing isn’t always where you’d want it. We map that out before we quote so you know exactly what the conversion touches. Call (877) 610-1318 for a free estimate.

Common Home Additions & ADU Problems We See in Pecan Grove Homes
- Foundation movement from Beaumont clay: The expansive soil that runs under Pecan Grove swells in wet months and shrinks during droughts. Additions without proper pier depth or soil treatment can pull away from the original slab within a few seasons.
- County permit surprises: Contractors who don’t regularly build in unincorporated Fort Bend County get delayed when the Drainage District asks for detention plans they never prepared. We anticipate those submittals from the first site visit and build them into your schedule.
- Post-Harvey elevation mismatches: Many Pecan Grove homes were elevated or rebuilt after 2017, while others remain on original slabs. Adding to an elevated home costs more than adding to a slab, and tying the two together requires an engineer who understands both conditions.
- Impervious cover limits: Fort Bend County restricts how much of your lot can be covered by structures and hard surfacing. A large addition or detached ADU may trigger detention requirements that change your site plan and your budget.
