Why Lodgewick ADU Houston Is Richmond’s Preferred Home Addition Contractor Company
Richmond homeowners have a specific set of headaches with additions, and we’ve seen most of them. Flat, clay-heavy lots in Fort Bend County need more fill and compaction than people expect. Master-planned communities like Aliana and Pecan Grove have HOA design-review boards that can delay a project two to four weeks if you don’t file early. And unincorporated areas outside Richmond city limits skip city permits but still answer to Fort Bend County’s floodplain office. Knowing these before you break ground is the difference between a smooth build and a stopped one. Our Home Addition Contractor team works with local engineers, HOA boards, and county inspectors every week.
Russ Delmar leads our Richmond work. He’s the one who walks your lot, checks the grade, and tells you straight what the soil, the HOA, and the county will require before you spend a dime. Every project carries The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written 365-Day Done Right Promise. If something isn’t right within a year, we come back and fix it. No phone tag, no finger-pointing. A live person answers our phones 24/7 at (361) 326-2313.

Second Story Addition Contractor in Richmond
A second-story addition contractor in Richmond has to solve a problem most of the country doesn’t deal with: Fort Bend County’s flat, expansive clay soil. Adding a second story to a 1980s or 1990s Richmond home means the existing slab and footings have to carry far more weight than they were poured for. In neighborhoods like Pecan Grove and Tara, we routinely find original slabs that are fine for one story but need structural review before vertical framing starts.
Structural load review
We hire a licensed structural engineer to check your existing foundation before any plans are finalized. That’s not a upsell. It’s the thing that tells us whether your second-story addition needs new footings, a beefed-up slab edge, or just standard framing. Richmond second-story additions typically run $180 – $310 per square foot, and the structural review usually adds $1,500 – $3,500 to the total.
Exterior match and curb line
Richmond HOAs in Aliana and other master-planned communities often require second-story additions to match the existing roofline and siding profile. We’ve used James Hardie fiber-cement lap siding on multiple Richmond second-story projects because it passes HOA review and holds paint better than vinyl in the humidity south of I-10. Budget $220 – $280 per square foot for a full second-story build with matching exterior.
Garage Addition Contractors in Richmond
Garage addition contractors in Richmond work on lots where the driveway approach, the HOA setback rules, and the county floodplain office all get a say. A garage addition on a Richmond lot isn’t just four walls and a roof. It’s engineered fill under the slab, drainage routing that satisfies Fort Bend County Drainage District, and framing that matches the house you’ve already got. We build 400 – 600 square foot garage additions throughout Richmond, including detached garages on larger lots in unincorporated Fort Bend County.
Slab prep and engineered fill
Richmond’s clay soil expands and contracts with every wet-dry season. Before we pour, we compact the pad and add 6 – 12 inches of select fill, depending on what the geotech report says. A typical two-car garage addition in Richmond runs $85,000 – $140,000, and fill plus compaction is usually $4,000 – $9,000 of that. Skipping it is how you get a garage slab that heaves at the corners in two years.
Bonus-room framing above the garage
If your lot is tight, we can frame a second-story bonus room over the new garage, the way we did on a 1990s tract home in Pecan Grove. That job was a 450-square-foot garage with James Hardie siding matched to the existing exterior and a framed bonus room above. Because the lot sat in unincorporated Fort Bend County, we coordinated floodplain review before foundation work and scheduled inspections through the county’s third-party engineering firm, not a city building department.
Trusted Brands We Service in Richmond
We work with materials and systems that make sense for Richmond’s climate and HOA standards. Mighty Buildings and Boxabl panels show up often on Richmond ADU and addition projects because they go up faster than stick-built and keep thermal performance tight through Fort Bend summers. Plant Prefab is another good fit for Richmond lots that need a compact, code-ready module. We stock trim, flashing, and touch-up materials locally so if your Richmond project needs a small fix after move-in, we aren’t waiting on a freight order. The brand you pick depends on your lot, your HOA, and your budget, and we’ll tell you which one fits before you sign anything.
Common Home Addition Contractor Problems We See in Richmond Homes
- Undersized fill and grading. Richmond’s flat, clay-heavy lots usually need 6 – 12 inches of engineered fill before a slab addition can be poured. Contractors who skip this save a few thousand dollars up front and leave you with a slab that shifts and cracks within two years.
- Skipped county floodplain permits. If your Richmond-area home is outside city limits, you may not need a city permit, but Fort Bend County still requires a floodplain development permit for structural additions. Missing this can halt work mid-project and trigger fines from the drainage district.
- HOA design-review delays. Communities like Pecan Grove and Aliana have design-review boards that can add two to four weeks before framing starts. Smart Richmond contractors file the design package the same week you sign the contract.
- Mismatched exterior materials. Humidity, sun exposure, and HOA requirements mean a sunroom or bump-out wrapped in the wrong siding will age differently than the original house. We match material type and profile, not just paint color.
Pricing for Home Addition Contractor in Richmond, TX
Home additions in Richmond are priced per square foot, but the per-foot number depends on what you’re adding. A ground-level room addition runs $140 – $260 per square foot. A second-story addition runs $180 – $310 per square foot because you’re paying for structural review, vertical access, and roof tie-in. A full garage addition runs $85,000 – $140,000 depending on size, finish, and whether you’re framing a bonus room above it. Engineered fill on Richmond’s clay soil adds $4,000 – $9,000. HOA design review adds time, not usually cost, but the structural review for vertical work adds $1,500 – $3,500. We give you a written price before work starts, and that price does not change at the door. Call (361) 326-2313 for a free, written estimate on your Richmond addition.

FAQs About Home Addition Contractor in Richmond
No city permit is required if your property sits in unincorporated Fort Bend County, but you will still need a Fort Bend County floodplain development permit for any structural addition. The county reviews drainage impact and may require engineered fill or a drainage plan before foundation work begins. Call (361) 326-2313 and we’ll check your specific parcel against county maps.
The existing foundation. Richmond’s clay-heavy soil means slabs from the 1980s and 1990s were rarely engineered for a second story, so a structural engineer usually has to review the slab and footings before vertical framing starts. That review adds $1,500 – $3,500, and if the slab needs reinforcing, the cost goes up from there.
A standard two-car garage addition in Richmond typically takes 10 to 14 weeks from the first shovel to final inspection, assuming the HOA design review is already done. If your community requires design-board approval, add two to four weeks before work starts. We give you a written timeline with your written price, and we hit the arrival windows we set.
Because the contractor used a cheaper siding or trim profile that doesn’t match the original house, and Richmond’s heat and humidity made the difference obvious within a few years. We match material type and profile, and we’ve used James Hardie fiber-cement on multiple Richmond projects specifically because it holds up to Fort Bend summers and passes HOA review.
Fort Bend County Drainage District can flag a property if the proposed addition sits in or near a drainage easement, which means you’ll need a drainage plan and possibly a larger setback before the county signs off. We coordinate that review directly with the county’s engineering firm, the same way we did on a Pecan Grove garage addition before any foundation work started. Call (361) 326-2313 for a free parcel check.
