Garage Conversion ADU in Bedford: What It Costs and What Actually Happens When Walls Come Open
A garage conversion ADU in Bedford typically runs $120,000-$185,000 all-in for an attached single-car conversion, drawings through final inspection, depending on what the existing structure reveals once we open it up. Detached conversions run $150,000-$230,000. The gap between the low and high end of those ranges almost always comes down to one thing: what’s hiding behind the drywall and under the slab of a home built between 1963 and 1985.

We’re Ellery ADU Studio, and we’ve designed, permitted, and built 900+ ADUs since 2015 under one contract at one written price. On Bedford’s landlocked, fully built-out plats, that means every project starts with a setback and lot-coverage analysis before we put a single number on paper. Call (971) 497-2402 to get a written price for your Bedford garage conversion, not a ballpark.
Key Takeaways:
- Bedford garage conversion ADUs run $120,000-$230,000 depending on attached vs. detached and what the structure reveals.
- Nearly every 1960s-1980s Bedford garage needs a panel upgrade before it can legally become a bedroom.
- Setbacks on Bedford lots often leave only 5-7 feet of rear-yard clearance, which dictates whether you can bump out or must stay within the existing footprint.
- Ellery ADU Studio quotes a written price before any work starts, per Haven Standard Clause 1. No “call for a quote” runaround.
Why Bedford Homeowners Choose Ellery ADU Studio for Garage Conversions
Bedford is not a growth suburb. There is no undeveloped land left, no big-lot opportunity to drop a backyard cottage. Almost every ADU project here is a retrofit: a garage conversion, a carport enclosure, or an interior split on a 1960s-1980s plat with tight setbacks and lot coverage already at or near the city’s limit. We know that before we walk the property, because we’ve worked enough Bedford homes to recognize the patterns: original 60-100 amp panels, single-car garages at 200-240 square feet, rear walls sitting 5-7 feet from the property line.
Nadia Ellery founded this studio in 2015 specifically around the permit set as the core product, not an afterthought. That matters in Bedford, where a garage conversion triggers code upgrades that a lot of contractors don’t mention until the wall is open. We name them in the written scope before you sign, and we price them. Our Garage Conversion ADU team is background-checked and uniformed, and a live person answers our phones 24/7.
Our Garage Conversion ADU Services in Bedford

Attached Garage Conversion
Attached single-car garages are the dominant conversion candidate across Bedford’s ranch and split-level housing stock, particularly in the neighborhoods between Harwood Road and Central Drive. These structures share a wall and often a roof plane with the house, which means the permit path is a residential remodel, not a separate structure permit. In practice, that usually simplifies the setback story, but it does not remove it. We start with a foundation and framing assessment, then write the allowance for what the walls will actually reveal: original knob-and-tube remnants, uninsulated cavities, or sill plates that have wicked moisture for 50 years. A typical Bedford attached garage conversion with a bathroom and mini-split runs $130,000-$170,000.

Detached Garage Conversion
Detached garages in Bedford are less common than attached, but they show up on 1970s lots where the garage sits behind the house at the lot’s rear edge. That rear placement is where the problem lives: a 5-foot rear setback on a garage that is already at the property line means any real conversion work triggers a variance conversation with the City of Bedford before drawings are final. We handle that variance application as part of the permit set. Detached conversions also need their own utility trench from the house, which adds a line item attached garages don’t have. Expect $150,000-$230,000 depending on trench length, panel location, and the scope of the structure’s envelope upgrade.

Carport Conversion
Carport conversions are a specific Bedford pattern: the 1960s house with an open carport that a previous owner semi-enclosed years ago without a permit. That unpermitted enclosure is a liability when you go to sell, and it complicates the ADU permit. Our job is to bring it to code, document what was done, and create a habitable envelope that meets current Texas energy requirements. On Bedford’s clay soils, a carport slab was rarely poured with habitable-structure footings, so we almost always saw-cut and pour a new thickened edge or retrofit the existing slab. Carport conversion ADUs in Bedford typically land in the $120,000-$165,000 range.

Garage Partition and Bathroom Add
Many Bedford homeowners do not want the whole garage converted. They want a bathroom, a laundry, and a partitioned studio space while keeping a storage bay or workshop. The structural work is lighter, but the code path is not. You still need a panel that can carry a water heater and electric appliances, an exterior door with proper clearance, and egress windows in the habitable half. We write the partition wall as part of the permit set so the conversion is documented and legal, not a handshake deal. Partition and bath conversions in Bedford run $85,000-$125,000, and we often pair them with a Garage Conversion ADU in Bedford phased plan if you intend to convert the remaining bay later.

Trusted Brands We Specify in Bedford Garages
Bedford garages from the 1970s have building envelopes that were never meant to be lived in. The brand choices we make are about closing that gap. We specify and coordinate prefab and modular systems from Abodu, Cover, and Dvele inside the same single contract, and we install James Hardie exterior products where an older garage wall is being rebuilt or reclad. Because most Bedford jobs involve a mini-split and building-envelope upgrade on a structure that baked in 140°F attic heat every summer since Nixon was in office, we favor closed-cell foam assemblies and heat-pump HVAC units that carry a documented performance spec. The brand decision is made in the permit set, not on the jobsite.
Common Garage Conversion ADU Problems We See in Bedford Homes

- 60-amp aluminum wiring from the 1970s. Open the wall on a Bedford garage built before about 1980 and you’ll find aluminum branch circuits sized for a garage door opener and one outlet. A bedroom, bathroom, and mini-split will not run on that. The panel upgrade to 200 amp is a required line item, and we write it into the scope up front, not as a discovery.
- 200-square-foot garages that fall below habitable minimums. Bedford’s original single-car garages often measure 200-240 square feet. Most jurisdictions require at least 220, and many require more for a full one-bedroom ADU. When the square footage is short, we absorb an adjacent utility closet or bump out the rear wall, which triggers a setback review on lots with only 5-7 feet of rear clearance.
- Uninsulated attic-floor framing. A 1970s garage ceiling has no thermal barrier between the living space and the attic above. Finish drywall over that and the first Texas summer pushes 140°F heat down through the ceiling. The habitable space fails. The fix is closed-cell foam at the roof deck or a properly vented insulation assembly, plus a mini-split sized for the real heat load.
- Sill plates and bottom plates rotted from slab moisture. Bedford’s clay soils hold water against foundation edges, and 50-year-old garage slabs were often poured without a moisture barrier. When we pull baseboards or open wall cavities, rotted wood is common. We price the repair allowance in the contract and document every discovery with a photo record you receive.
Pricing for Garage Conversion ADU in Bedford, TX
A garage conversion ADU in Bedford runs $120,000-$185,000 for an attached conversion and $150,000-$230,000 for a detached one, including drawings, permit set, construction, and final inspection. The largest cost drivers in Bedford are the panel upgrade (typically $3,500-$6,000), the building-envelope work to make a 1970s garage habitable (closed-cell foam, mini-split, fresh-air damper), and the foundation work required on North Texas expansive clay. A garage partition with a bathroom runs $85,000-$125,000. A full garage JADU with a kitchenette and separate entrance typically lands $140,000-$175,000.

Under Haven Standard Clause 1, you receive a written price before any work begins. That price includes named allowances for the discoveries we know are likely in Bedford: rotted sill plates, undersized framing, inadequate footing depth. If a discovery exceeds the allowance, we price the change order in writing and you approve it before we touch the wall. Call (971) 497-2402 and we will put your Bedford garage conversion price on paper, not in a verbal range.
What It Actually Looks Like When We Open a Bedford Garage

On a 1972 split-level off Harwood Road, our crew opened a 220-square-foot attached single-car garage to find original 60-amp service, no insulation, and a rear wall 6 feet from the property line. We pulled permits, upgraded the panel to 200 amp, added closed-cell foam and a mini-split with a fresh-air damper, bumped out the rear wall 3 feet after a setback review, and delivered a permitted one-bedroom JADU with approved change orders for every discovery.
That is the job in Bedford. Not a drywall-and-paint weekend project, but a code-compliant conversion on a tight plat where the rear setback dictates how far you can stretch the original footprint. Every line item was written before the work started, and the client received a photo record of what was found and what was done on every visit. That is what we mean when we say the permit set is the product.

FAQs - Garage Conversion ADU in Bedford
Homes in Bedford built between roughly 1963 and 1985 almost universally shipped with 60-100 amp electrical panels sized for the era: a few lights, a garage door opener, maybe a freezer in the corner. A habitable ADU with a bedroom, bathroom, and mini-split heat pump will not run on that. The panel upgrade to 200 amp is the most common first line item on a Bedford garage conversion, and it typically runs $3,500-$6,000 depending on how far the service drop is from the municipal transformer. We write it into the contract before work starts. Call (971) 497-2402 for an exact figure on your panel.
You usually cannot convert a garage under 220 square feet into a legal dwelling without adding square footage, because most jurisdictions require that minimum for habitable space. Bedford’s original single-car garages often measure 200-240 square feet. When you’re short, we either absorb an adjacent utility closet inside the existing envelope or bump out the rear wall. The bump-out triggers a setback review, and on Bedford lots where rear-yard clearance is only 5-7 feet, that review decides how much you can add. We run that analysis as step one. Get a written assessment by calling (971) 497-2402.
North Texas expansive clay moves with moisture, and Bedford’s older subdivisions sit directly on it. When you add a bathroom to a converted garage, you add concentrated water lines, drains, and tile work, all of which respond badly to slab movement. We assess the existing slab first: pour depth, presence of a moisture barrier, and any existing cracking patterns. On older carport or garage slabs without habitable footings, we saw-cut and pour a thickened edge or install helical piers before setting tile. That geotechnical step adds $4,000-$9,000 on typical Bedford clay lots, and we name it in the written scope.
The building-envelope upgrade is the biggest cost driver on Bedford garage conversions, specifically the insulation and HVAC work required to make a 1970s garage habitable in a Texas climate where summer attic temperatures exceed 140°F. The garage structure was built as unconditioned space. Making it a legal dwelling means closed-cell foam at the roof deck or walls, a properly sized mini-split, a fresh-air damper for ventilation code, and likely a ducted return. That work can run $20,000-$35,000 before you touch finishes. We price it in the contract so the number doesn’t move later. Call (971) 497-2402 to have your garage evaluated.
We write the surprise into the contract as a named allowance. On a Bedford garage from the 1960s-1980s, we expect sill plate rot, undersized framing, or both, and we price a repair allowance for it before work starts. If the work needed exceeds that allowance, we document what we found with photos, price the change order in writing, and you approve it before we proceed. Under Haven Standard Clause 5, the scope is locked at signing, with no door-side upsells. You see every discovery and every dollar before it is spent. Call (971) 497-2402 for a written price on your Bedford conversion.
