We’re Garage Conversion Contractor specialists serving Channelview directly.

Why Lodgewick ADU Houston Is Channelview’s Preferred Garage Conversion Contractor Company

Russ Delmar, who leads our team, has been managing garage conversions since 2010 as part of the Kingswell family of home-service companies. That’s fifteen years of watching homeowners get burned by vague quotes and skipped permits – and building a company that doesn’t do either.
The Kingswell Guarantee is the reason Channelview homeowners call us back for second projects and refer us across the fence. Here’s what it means, written plainly: a written price before the first nail goes in, a defined arrival window for every workday, a clean job site, and a written guarantee on every build. If the work isn’t right within 365 days, we come back and make it right. That’s the 365-Day Done Right Promise, and you get it in writing on every project. Russ wouldn’t run it any other way.
Calls to (361) 326-2313 are answered by a live person, 24 hours a day. Not a voicemail loop. When you call to ask about permit fees in unincorporated Harris County or whether your slab can handle a bedroom, you get an answer on the spot.
Every technician on your property is background-checked and uniformed. You’ll always know who’s walking onto your Channelview property and why they’re there.
Garage to Bedroom Conversion in Channelview
A Garage to Bedroom Conversion in Channelview is the most common project we price, usually because a family has outgrown the house but not the lot. It means turning your existing garage into a code-compliant sleeping room with proper egress, insulation, HVAC, and electrical – not just drywalling over the garage door and calling it done. In Channelview, that typically runs $48,000 to $75,000 depending on whether you’re converting an attached or detached garage and how much foundation work the slab needs.
What Harris County Actually Requires
Channelview is unincorporated Harris County, so your permit comes from Harris County Engineering, not a city building department. Houston’s permit fee schedule doesn’t apply here. The county requires a floor plan, electrical plan, and energy compliance documentation. If you skip this step and build without a permit, a future sale or insurance claim becomes a liability.
Foundation Work on Channelview Clay
Many Channelview homes sit on expansive clay that shifts with rain and drought. A garage slab poured decades ago usually lacks a vapor barrier and may have settled or cracked. Converting to a bedroom means leveling, possibly saw-cutting for plumbing, and adding a moisture barrier before flooring goes down. We’ve seen homeowners try to skip this and watch floor tiles crack within a season.
Garage Conversion ADU in Channelview
A Garage Conversion ADU in Channelview is a full accessory dwelling unit – bedroom, bath, kitchenette, separate entrance, and dedicated electrical service. It’s the highest-value option because it creates legal rental income or multi-generational housing on your existing lot. In Channelview, a detached garage ADU conversion runs $145,000 to $210,000 depending on square footage, finishes, and whether we’re rebuilding from the slab up.
The Sterling Green Project
Our crew converted a detached two-car garage on Cimarron Street in Sterling Green into a 480-square-foot ADU with a bedroom, bath, and kitchenette. We upgraded the existing slab, reframed the garage door opening for a wall with a window, and brought the electrical service up to Harris County code for a separate dwelling unit – including a dedicated subpanel and new HVAC mini-split. That’s what “done right” looks like, and it passed county inspection on the first visit.

Electrical Load and the Separate Dwelling Unit Rule
Harris County inspectors treat an ADU differently from a bedroom conversion. A bedroom taps your existing panel. An ADU is a separate dwelling unit, which triggers a load calculation and often a service upgrade or dedicated subpanel. DIY converters get caught here at final inspection – and then they’re paying us to fix it anyway, on top of their original spend.
Trusted Brands We Service in Channelview
We work hands-on with materials and systems from Mighty Buildings, Tuff Shed, and Plant Prefab, matched to your lot, budget, and timeline. For Channelview projects where a prefab panelized shell makes sense – especially detached ADUs on tight lots with limited crane access – these brands cut weeks off the schedule. We order with Channelview lead times in mind and stage deliveries to your street, whether that’s a quiet cul-de-sac in Woodforest or a corner lot near North Shore.
Common Garage Conversion Contractor Problems We See in Channelview Homes
- Assuming Houston permit rules apply. Channelview is unincorporated Harris County, so using Houston’s fee schedule or plan requirements leads to rejected permit applications. We’ve seen homeowners submit Houston paperwork and lose three weeks before corrections.
- Under-scoping the foundation on older slab garages. Expansive clay under Channelview shifts more than people expect. A thin floor patch can crack within one wet-dry cycle. Proper conversion means evaluating the whole slab, not just the cracked corner.
- Skipping the separate dwelling unit electrical load calc. Harris County inspectors often require a service upgrade or dedicated subpanel for an ADU. DIY converters discover this at final inspection, which stalls the whole project.
- Keeping the garage door in place on a “converted” room. A garage door is not a wall. It leaks air, lets in pests, and won’t pass a bedroom egress or energy inspection. You’ll need it reframed, insulated, and finished with a real exterior wall.

FAQs About Garage Conversion Contractor in Channelview
Yes. Channelview is unincorporated Harris County, so garage conversions require Harris County Engineering permits – not a city permit from Houston or Baytown. You’ll need a floor plan, electrical plan, and energy documentation. Call (361) 326-2313 and we’ll tell you exactly which permits apply to your project and what they’ll cost.
Your appraised value typically increases by roughly the market value of the new square footage – for a $180,000 ADU conversion, expect a noticeable but not dollar-for-dollar increase after the Harris Central Appraisal District reassesses. A permitted ADU adds value a buyer can finance; an unpermitted conversion doesn’t. Call (361) 326-2313 and we’ll walk you through the math for your specific Channelview property.
Maybe. Older Channelview slabs on expansive clay often lack vapor barriers and have settled unevenly. A bedroom needs a level, moisture-protected floor. We’ll evaluate your slab before pricing – some need only patching and a barrier, some need section replacement. We’ll tell you which, in writing, before work begins. Call (361) 326-2313 for a free slab assessment.
No. A garage door can’t pass a bedroom egress inspection, and it won’t hold conditioned air. It gets reframed into a real wall – sometimes with a window or French door in its place. That’s non-negotiable for a permit. Call (361) 326-2313 and we’ll show you what the replacement wall looks like and what it costs.
Plan on 10 to 16 weeks: two to four for Harris County permit review, four to eight for construction, and one to two for inspections and corrections. Prefab systems from brands like Mighty Buildings can compress the build phase. Call (361) 326-2313 and we’ll give you a project calendar tied to your specific scope.
If you’re still weighing options or just want to know what your Channelview garage could become, call (361) 326-2313. A live person answers. The estimate is free, the scope is written, and the number we put down is the number you’ll pay.
