That’s the honest number we give homeowners up front, before any work starts. At Lodgewick ADU Houston, our Garage Conversion Contractor team knows the neighborhoods around Quail Valley, Lake Olympia, and Sienna because we’ve built there.

Why Lodgewick ADU Houston Is Missouri City’s Preferred Garage Conversion Contractor Company
Homeowners in Missouri City tell us the same thing over and over: they got a verbal price, then the number moved once the crew showed up. That’s exactly what we don’t do. Led by Russ Delmar, our garage conversion work follows The Kingswell Guarantee: a written price before work begins, a real arrival window, a clean job site at the end of every day, and a written guarantee on the finished project. If something isn’t done right, we come back and fix it within the 365-day period. That’s the Done Right Promise, in writing, on every job.
Our crews serve Missouri City directly, with scheduling coordinated out of our Houston office. We’ve converted garages off Cartwright Road, in the older sections of Quail Valley, and in newer subdivisions near Highway 6. We know the difference between a 1980s slab-on-grade build and a post-tension slab that needs an engineer’s sign-off before plumbing cuts. That local knowledge changes how we bid and how we sequence inspections.
Every technician who shows up at your Missouri City home is background-checked and in uniform. You’ll know who’s on your property. And when you call with a question about your build, a live person answers. Not a voicemail loop. Not a chatbot. That matters when you’re four weeks into a conversion and you need a straight answer.
Garage Conversion ADU in Missouri City
A Garage Conversion ADU in Missouri City means turning an existing garage into a legal accessory dwelling unit: a self-contained living space with its own sleeping area, bathroom, kitchenette, and separate entry. For homeowners in subdivisions like Quail Valley and Lake Olympia, this is often the smartest path to rental income or multi-generational housing, because attached garage conversions typically face fewer HOA hurdles than detached structures. A straightforward conversion with a full bath and kitchenette runs $110,000 to $145,000 in this market. Add a separate electrical service or upgrade the slab and you’re looking at the upper end of that range or higher.
Attached Garage to Living Space
An attached conversion works from the existing footprint. We reframe the garage door opening, install a wall assembly matched to your exterior, tie into the home’s foundation, and run new plumbing and electrical. HOA covenant review is usually lighter here than for a detached build.
Detached Garage ADU
A detached garage on a Missouri City lot gives you more design freedom, but it comes with deeper utility runs and often a stricter HOA or deed restriction review. We handle the pre-construction covenant check before you spend a dollar on demo.
Garage Apartment Conversion in Missouri City
A Garage Apartment Conversion in Missouri City creates a full residential unit with a distinct addressable layout: separate living area, bedroom, kitchen, and bath. This is the build for homeowners who want true rental income, an in-law suite, or a long-term plan to house a college student or aging parent. With kitchen, bath, and independent HVAC, expect $120,000 to $160,000 on Missouri City. The cost driver is usually the slab. Many garages in this area sit on post-tension concrete, and you cannot cut into it for plumbing without a structural engineer’s stamp and a revised city plan set.
Garage to Bedroom Suite
If the goal is a primary bedroom or guest suite rather than a full apartment, we can scope the project tighter: bedroom, bath, closet, and basic wet bar. This keeps the cost closer to $85,000 to $110,000 and shortens the permit review in Missouri City.
Full Apartment with Kitchen and Bath
A full apartment conversion means a dedicated mini-split or ducted HVAC run, a separate subpanel if your existing panel lacks capacity, and a second means of egress. In older Missouri City homes, we often find the electrical panel has no room for a new 240V circuit, which is why our estimates include panel capacity checks up front.
Trusted Brands We Service in Missouri City
Our Missouri City customers regularly ask about panelized and prefab components from companies like Dvele, Mighty Buildings, and Boxabl. Russ Delmar and the Lodgewick crew have hands-on experience integrating these systems, along with James Hardie siding assemblies that hold up to Missouri City’s humid summers and clay-heavy soils. Because we stock common materials locally and pre-order prefab panels before demo starts, we don’t leave a Missouri City job site waiting on a two-week shipping delay. That keeps your calendar predictable.
Common Garage Conversion Contractor Problems We See in Missouri City Homes
- Demo before HOA approval: Quail Valley and Lake Olympia homeowners sometimes start pulling out garage doors before the architectural review committee signs off. The result is a stop-work order over window placement or exterior finish. We file the covenant review before demo, not after.
- Post-tension slab surprises: Many Missouri City garages sit on post-tension concrete. Cutting into that slab without an engineer’s report can compromise the structural tendons. Our estimates always include a slab assessment when plumbing is planned.
- No HVAC or panel capacity: A 1990s Missouri City garage often has no ducting and a panel that can’t support a mini-split plus kitchen circuits. Bidding it as a simple finish-out leads to price jumps mid-project. We check both before we quote.
- Floodplain clearances: Parts of Missouri City fall within FEMA-regulated flood zones. A garage conversion ADU may require elevation documentation or floodplain clearance before the city will issue a permit. We handle that paperwork as part of the build.

FAQs About Garage Conversion Contractor in Missouri City
Missouri City generally requires a separate address for a detached ADU but often allows an attached garage conversion to share the primary home’s address and utility meter. The requirement hinges on whether the unit has its own kitchen, its own exterior entry, and its own electrical subpanel. We confirm the exact requirement with the city during pre-construction plan review, before you commit to the build. Call (361) 326-2313 for a free estimate and we’ll walk through your specific setup.
Quail Valley deed restrictions typically allow attached garage conversions with fewer conditions than detached ADUs, which are often restricted outright. The HOA’s architectural review committee still has to sign off on window placement, exterior finishes, and roof lines before the city will issue a building permit. We file that covenant review early, because a denied exterior scheme can stall the whole job. If your property falls under Quail Valley or Lake Olympia covenants, we verify what’s allowed in writing before demo starts.
A typical Missouri City garage conversion runs 10 to 16 weeks from permit submission to final inspection. Plan review with the city takes 2 to 4 weeks, HOA architectural review adds 2 to 6 weeks if required, construction runs 6 to 10 weeks, and the separate electrical, plumbing, and framing inspections land at defined milestones. Post-tension slab engineering and floodplain clearances can extend the front end of that calendar. We give you a written schedule at contract signing. Call (361) 326-2313 to talk through your timeline.
Adding a bathroom where one wasn’t originally scoped, upgrading the electrical panel, and running new HVAC ductwork are the three biggest mid-project cost movers in Missouri City. Other drivers include post-tension slab plumbing cuts that require an engineer, HOA-mandated exterior material upgrades, and floodplain documentation that wasn’t identified in the initial quote. Our estimates are line-item and free, so you see every cost driver before work begins. Call (361) 326-2313 for an exact quote.
If your Missouri City lot falls within a FEMA-designated flood zone, yes, the city will require floodplain clearance or elevation documentation before issuing a conversion permit. We check flood maps for every Missouri City project during the initial site visit, so this doesn’t become a surprise later. If clearance is needed, we manage the documentation as part of the permitted build. Call (361) 326-2313 to schedule a free estimate and we’ll check your address.
