A garage conversion in Galena Park typically runs $85,000 – $145,000 for a full ADU with a bathroom and kitchenette, and most projects take 10 – 14 weeks from permit application to final inspection. That’s the straight answer. The lot coverage rules, the age of your garage slab, and whether the city classifies your project as an ADU or a finished room all move that number, and we’ll walk you through each one before you spend a dime.
Lodgewick ADU Houston serves Galena Park homeowners who want livable square footage without buying a bigger lot or moving out of the neighborhood they already know.

Why Lodgewick ADU Houston Is Galena Park’s Preferred Garage Conversion Contractor Company
Galena Park homeowners have dealt with enough contractors who give a lowball number over the phone and a different one at the door. We don’t operate that way. Every project starts with a written price before any work begins, and that price doesn’t change unless you change the scope. It’s the Kingswell Guarantee, and it’s been how we’ve worked since 2010.
Our reputation in Galena Park is built on showing up when we say we will. When we schedule a crew for a garage conversion off North Main Street or near Tice Elementary, we give you a defined arrival window and we hit it. The team arrives in uniform, background-checked, and ready to work the full day. No disappearing for three weeks. No unanswered texts.
Local knowledge matters on garage conversions because Galena Park has specific rules that a contractor from across town won’t know until it’s too late. The city’s 25% lot coverage rule for accessory structures catches a lot of people off guard. We factor that into the plan before you pay for drawings. When you work with our Garage Conversion Contractor team, you get people who know the local permitting path and the common slab issues under older garages here.
Garage Conversion ADU in Galena Park
A Garage Conversion ADU in Galena Park is the process of turning an existing garage structure into a separate, legal dwelling unit with its own entrance, bathroom, kitchenette, and sleeping area. For most Galena Park lots in the 5,000 – 7,000 sq ft range, a single-story garage-to-ADU keeping the footprint under 600 sq ft fits within the city’s 25% lot coverage rule. Expect to spend $95,000 – $145,000 depending on whether you’re converting an attached garage with existing utilities nearby or a detached structure that needs a new sewer line and electrical service run.
The big distinction in Galena Park is whether the city classifies your project as an ADU or a finished room. An ADU requires its own entrance, a bathroom, and a kitchen with cooking facilities. A finished room with a half bath is cheaper but won’t count as a legal dwelling unit, which matters if you plan to rent it out or use it for multi-generational living.
Attached Garage ADU Conversions
Attached garage conversions in Galena Park run $85,000 – $115,000 when the existing garage shares a wall with the main house. Utilities are already close, which saves on trenching. The tradeoff is fire separation: the city requires a fire-rated wall between the ADU and the main dwelling, and that adds cost if the existing wall wasn’t built to that standard.
Detached Garage ADU Conversions
Detached garage ADUs in Galena Park run $105,000 – $145,000 because you’re running new water, sewer, and electrical service from the main house to a separate structure. Detached garages on the older 1950s – 70s lots here often sit on a 3-inch floating slab with no perimeter footing, which means we usually need to pour a reinforced edge beam before framing interior walls.
Garage Apartment Conversion in Galena Park
A Garage Apartment Conversion in Galena Park takes a garage structure and turns it into a rentable or multi-generational living unit, typically with a full kitchen, a 3-piece bathroom, and a separate address if the city allows it. These projects run $110,000 – $155,000 in Galena Park because they require a separate electrical service or a load-calculation letter from a licensed electrician, plus a sewer connection that often means cutting through an existing driveway or patio slab.
Many homeowners in Galena Park pursue a garage apartment conversion specifically to generate rental income, whether that’s a long-term tenant or a family member who pays below market. The city’s ADU rules allow rental use, but you’ll need to pull the right permits and pass final inspection before anyone moves in. We handle that entire sequence.
Garage to Bedroom Conversion
A garage to bedroom conversion in Galena Park runs $40,000 – $70,000 when you’re adding a sleeping space and a half bath without a full kitchen. This is the right move when you need a ground-floor bedroom for an aging parent or a quiet office that doubles as a guest room. The city classifies this as a finished room, not an ADU, which simplifies the permit path and keeps the project at the lower end of the cost range.
Garage to Living Space Conversion
Converting a garage to living space without a kitchen or bathroom starts around $35,000 – $55,000 in Galena Park. You’re looking at insulation, drywall, flooring, HVAC tie-in, and electrical upgrades. It’s a straightforward project on paper, but the pre-1978 housing stock here can hide asbestos siding or lead paint on the garage exterior, which adds 10 – 15% to the job when discovered during demo.
Trusted Brands We Service in Galena Park
Our Galena Park garage conversions use materials and components from brands we know hold up in this climate. We work with Dvele modular counter systems for compact ADU kitchenettes, Mighty Buildings panels where a homeowner wants faster framing with less on-site waste, and James Hardie siding for exteriors that stand up to Gulf Coast humidity and the occasional flood-watch season. We keep a local stock of common replacement parts and finishing materials for our Galena Park jobs, which means we don’t lose a week waiting on a backordered door or a specialty drain fitting. When your project uses a specific brand, we order early and verify delivery before demo day.
Common Garage Conversion Contractor Problems We See in Galena Park Homes
- Mistaking the garage slab for a real foundation. Many Galena Park garages from the 1950s – 70s sit on a 3-inch floating slab with no perimeter footing. Adding plumbing and interior walls on that slab without a reinforced edge beam leads to settling and cracking within a few years.
- Asbestos and lead paint on pre-1978 detached garages. Galena Park’s housing stock is old enough that garage siding and paint frequently contain asbestos or lead. Abatement adds 10 – 15% to the total cost when discovered after demo starts, which is why we test before we tear into anything.
- Failing the city’s electrical inspection on the first pass. Galena Park requires a separate electrical service or a load-calculation letter from a licensed electrician for an ADU with a kitchen. Installing a range and a mini-split on the existing garage panel almost always fails inspection the first time. We size the panel and run the load calc before framing begins.
- Ignoring the 25% lot coverage rule. A full second-story ADU is often out of reach on Galena Park’s 5,000 – 7,000 sq ft lots because accessory structures have a 25% lot coverage limit. A single-story conversion under 600 sq ft usually fits. We do the coverage math during the estimate, not after you’ve paid for plans.

FAQs About Garage Conversion Contractor in Galena Park
Galena Park requires a legal ADU to have its own separate entrance, a full bathroom, and a kitchen with cooking facilities, plus compliance with the city’s 25% lot coverage rule for accessory structures. A finished room with a half bath and no kitchen does not qualify as an ADU and cannot be rented as a dwelling unit. If rental income or a legal second unit is your goal, we design to the city’s ADU standard from day one. Call (361) 326-2313 for a free estimate and we’ll map the exact requirements for your lot.
A garage conversion in Galena Park is cheaper than building a new detached ADU because the structure, roof, and sometimes the slab already exist, which saves $30,000 – $60,000 in framing and foundation work. The hidden cost is the existing slab: many Galena Park garages have only a 3-inch floating slab with no perimeter footing, so plumbing and interior walls require a reinforced edge beam that adds $8,000 – $15,000. We inspect the slab during the estimate so that cost is in your written price up front, not a surprise later. Call (361) 326-2313 and we’ll check your garage in person.
A typical garage conversion in Galena Park takes 10 – 14 weeks from the day we submit the permit application to the day the city signs off on final inspection. The permit review itself usually takes 2 – 4 weeks, demo and slab work 1 – 2 weeks, framing and rough-in 2 – 3 weeks, and finishes 3 – 4 weeks. Delays usually come from the city’s inspection queue or a change in scope you request mid-project, not from our crew disappearing. We give you a written schedule at the start. Call (361) 326-2313 to get your project on the calendar.
The most common change order on a Galena Park garage conversion comes from discovering asbestos siding or lead paint on pre-1978 garage structures, which triggers abatement that adds 10 – 15% to the job. The second most common is an undersized electrical panel that fails the city’s ADU inspection, which is why we run a load calculation before framing begins. We test for hazardous materials before demo so the written price you get is the price you pay. Call (361) 326-2313 for an estimate that accounts for your garage’s actual condition.
No, you cannot live in the garage conversion during construction in Galena Park because the city requires a certificate of occupancy before any dwelling unit is legally habitable, and living there mid-project creates fire and life-safety issues that will fail inspection. You can remain in the main house during the work since the garage is a separate structure or a sealed-off part of the home. We schedule noisy demo and framing work to minimize disruption to your daily routine. Call (361) 326-2313 to talk through the timeline for your Galena Park project.
