An ADU company in Houston builds accessory dwelling units, garage conversions, and home additions on lots where the existing home already stands. Most Houston jobs we see involve clay soil, flood-plain rules, and older ranch houses from the 1960s and 1970s that need foundation and electrical upgrades before any new structure goes up. If you’re weighing a backyard unit or a garage conversion in Houston, call (361) 326-2313 for a free estimate and a written price before anything starts.
Why Houston Homes Are Different
Houston’s housing stock runs older than people expect. A lot of homes inside the Loop and across neighborhoods like Sharpstown, Oak Forest, and Meyerland were built between 1955 and 1980, which means original wiring, cast-iron drain lines, and slab foundations that have shifted through decades of wet-dry clay cycles. That matters for ADU work: an attached addition or garage conversion often needs pier work or a structural engineer’s sign-off before framing begins, and experienced Houston crews plan for it from day one.
Climate shapes the job too. Houston’s heat and humidity punish cheap materials, so we spec Hardie plank or similar fiber-cement siding on exterior walls instead of wood, and we size HVAC for August, not March. Heavy rain events mean drainage has to move water away from the new foundation, not toward it. Permitting realities also differ by area: some neighborhoods inside Houston city limits have deed restrictions or older subdivision rules, and the city permitting path for an ADU depends on whether the unit is attached, detached, or a garage conversion. We walk every Houston homeowner through that before a permit is filed.
Our Main Houston Services
Houston homeowners usually reach out about two things: adding square footage onto the main house, or turning an existing garage into living space. Each gets its own deep-dive page below.
Home Addition Contractor in Houston
A Houston home addition extends the footprint of your current house, whether that’s a primary suite, a den, or a second story over a single-story ranch. These jobs almost always involve foundation work because Houston clay expands and contracts, so the new slab or pier-and-beam section has to be engineered to move with the existing one. We also contend with a lot of original flat roofs on older Houston homes, so tying in rooflines without creating a leak is a core part of the work. Home Addition Contractor in Houston covers full pricing, timelines, and what to expect from the permit process.
Garage Conversion Contractor in Houston
A garage conversion turns an attached or detached garage into a finished living space. In Houston, a lot of these garages were never insulated and sit on slabs that slope toward the alley, so the first step is often leveling, moisture control, and confirming the slab can carry the new loads. Detached garage conversions are popular in neighborhoods like Garden Oaks and Timbergrove, where lots are wider and the garage sits far enough back to feel like a separate little house. We also deal with Houston’s old sub-panels, many of which need upgrading to support the new mini-split or windowless bedroom circuits. Garage Conversion Contractor in Houston has the full breakdown.
ADU Builders in Houston
ADU builders in Houston construct a smaller, independent dwelling on the same lot as the main house: a backyard cottage, a detached suite, or a prefab unit set on a new foundation. Houston’s combination of clay soil, heavy rain, and strict flood-plain mapping means the site work dictates the budget more than any other factor. We work with Dvele, Boxabl, and Plant Prefab units and know which Houston lots they’ll fit, what foundation type each requires, and how to get the utilities tied in so the unit actually functions as a home, not a campsite. ADU Builders in Houston explains the full ADU path from lot check to final inspection.
