Fielding ADU Dallas is an independently owned and operated member of the Garrison Partners family. Since 2006, the organization has built to The Garrison Standard: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year. For Carrollton homeowners, that means a Garage Conversion Contractor who puts everything on paper before the first nail is driven.
Why Fielding ADU Dallas Is Carrollton’s Preferred Garage Conversion Contractor Company
We work in Carrollton every week. Our crews know the difference between a 1960s ranch near Josey Ranch and a 1980s two-story off Rosemeade Parkway. That local familiarity changes how we bid the job, how we sequence inspections, and how long the work actually takes.
Reed Calloway leads our team, and he insists on the same discipline on every Carrollton job: the price goes in writing before demolition starts, the permit goes on the board before the first inspection, and every crew member on your property is background-checked and uniformed. You won’t wonder who that person in your driveway is.
If the work fails inside the first year, The Garrison Standard covers it. We come back and correct the defect at no charge. That guarantee is written on paper, not promised in a handshake.
Carrollton homeowners call us because they’ve already been through a contractor who moved the price at the door or left the permit board empty. We don’t do that. Our Carrollton customers get a fixed price, a written scope, and a crew that shows up.
Garage Conversion to Living Space in Carrollton
Garage Conversion to Living Space in Carrollton means turning an underused garage into conditioned square footage: a family room, a home office, a playroom, or a guest suite. The permits, the insulation requirements, and the mechanical work all follow Carrollton’s residential building codes, and on older lots, that often means upgrading the electrical panel and running new circuits before anything else happens.
A typical garage-to-living-space conversion in Carrollton runs $85,000 – $125,000 depending on whether you’re adding a bathroom, a kitchenette, or both. Attached garages cost less to convert because the roof and one or two walls already tie into the house. Detached garages run higher because we’re pulling new utility lines across the yard.
Attached Garage Conversions
Attached garages share a wall with the house, which means the conversion can often tie into the existing HVAC system and keep the roofline intact. On Carrollton’s ranch homes, we frequently see the garage slab sitting lower than the main floor, so we frame up the floor system to match. Party-wall considerations apply when the garage wall is close to the neighbor’s fence line, and we handle that notice before any demolition starts.
Detached Garage Conversions
Detached garages in Carrollton, especially in neighborhoods near Josey Ranch Lake and the historic downtown, often sit on their own slab with a 2-inch cast iron sewer line. Those lines typically need sleeving or replacement before a bathroom can pass inspection. We also account for the clay soil’s shrink-swell behavior when trenching new plumbing between the house and the detached structure.
Garage to Bedroom Conversion in Carrollton
Garage to Bedroom Conversion in Carrollton is one of the most common projects we take on for homeowners with aging parents, adult children, or a rental plan. The city’s ADU ordinance requires owner occupancy on single-family lots, so this type of conversion is designed and permitted as an accessory unit tied to the primary residence, not as a standalone rental.
A garage-to-bedroom conversion in Carrollton typically runs $45,000 – $70,000 when it’s a simple sleeping quarters with a closet and egress window, and $90,000 – $140,000 when you add a bathroom and kitchenette. The egress window requirement is non-negotiable: a bedroom must have a second exit, and in older garages, that means cutting a new opening in a masonry or siding wall.
Garage to Primary Bedroom Suite
If you’re adding a primary suite with a full bath, the plumbing becomes the biggest cost driver. On Carrollton’s slab-on-grade homes, we’re cutting concrete to reach the existing drain lines, and that’s where the clay soil conversation starts. We size the HVAC for a bedroom’s overnight heating and cooling load, which is different from what a garage shell needs.
Garage to Guest Bedroom
A guest bedroom conversion can be simpler, especially if you skip the bathroom and keep the half-wall between house and garage. The permit still requires insulation in the walls and ceiling, a proper egress window, and a heating source. In Carrollton’s humid summers, we recommend a dedicated ductless mini-split rather than overloading the existing central system.
Trusted Brands We Service in Carrollton
Fielding ADU Dallas works with leading prefab and modular platforms, including Abodu, Plant Prefab, and James Hardie siding systems. We also handle conventional builds using Tuff Shed-style structures for garages that can be adapted rather than demolished. For Carrollton customers, this means we can match the right construction method to your lot, your foundation condition, and your budget. Prefab panels can cut weeks off a garage-to-ADU timeline, while conventional framing gives you more flexibility on an irregular footprint. We keep a full inventory of common parts for Carrollton’s housing stock, so we’re not waiting on a supply house in Fort Worth when your inspection is scheduled for Thursday.
Common Garage Conversion Contractor Problems We See in Carrollton Homes
- Owner-occupancy permit stops. Carrollton’s ADU ordinance requires the owner to live in the primary residence. If the city finds the main house is tenant-occupied, the project stops mid-inspection. We verify occupancy status before we pull the permit, so you don’t lose a month.
- Party-wall and fence-line friction. On narrow lots near downtown Carrollton and along Rosemeade, the shared fence is sometimes inches from the garage wall. Demolition without a proper party-wall notice triggers neighbor complaints and can stall the job. We handle the notice before the sledgehammer comes out.
- Clay soil and cracked plumbing. Carrollton sits on high shrink-swell clay. New plumbing run under an existing slab shifts when the soil finally gets a wet-dry cycle. We spec sleeved lines and proper bedding so the first North Texas rain doesn’t crack a fresh drain.
- Undersized HVAC for converted space. A garage shell isn’t conditioned, so jumping the existing central system’s capacity calc is a mistake. On 105°F Carrollton days, an undersized unit can’t keep a converted bedroom below 80. We size the load and install dedicated units where the math says to.
Pricing for Garage Conversion Contractor in Carrollton, TX
Here’s where Carrollton homeowners usually land:
- Garage to living space (attached): $70,000 – $110,000

What moves the number: whether the garage is attached or detached, whether you’re adding a bathroom, the condition of the existing slab and sewer line, and whether the electrical panel has capacity. A 1968 ranch near Josey Ranch with a 2-inch cast iron line will cost more than a 1990s attached garage with modern plumbing. That’s not a surcharge; that’s the actual work. We give you a written line-item quote before any work starts, and the number you approve is the number on the final invoice. No change orders because we guessed wrong.

FAQs About Garage Conversion Contractor in Carrollton
Carrollton requires the property owner to live in the primary residence for an ADU on a single-family lot. We confirm your occupancy before we pull the permit, which avoids a stop-work order if the city inspector finds the main house is tenant-occupied. The rule doesn’t add time if we plan for it; it adds time if we don’t. Call (903) 342-8977 for a written timeline on your property.
Yes, if the garage wall is close to the property line or shared fence, Carrollton expects a party-wall notice before demolition. We prepare and deliver that notice before we touch a wall. It saves you a neighbor complaint that can stall the permit and poison the rest of the job. Call (903) 342-8977 and we’ll walk you through the notice step for your specific lot.
Yes, but the cast iron line usually must be sleeved or replaced to meet current code before the bathroom is inspected. On Carrollton’s older homes, especially 1960s and 1970s slabs, we regularly sleeve 2-inch cast iron under the garage floor. We’ll show you the line condition in writing before you commit. Call (903) 342-8977 to schedule a site look.
We follow Carrollton’s posted construction hours and keep noisy work like saw-cutting and slab breaking inside the allowed window. On narrow lots near downtown or along Josey Lane, that means we stage materials on the driveway, not the street, and we keep the site swept so building dust doesn’t end up on the neighbor’s car. If your lot is tight, tell us when you call (903) 342-8977 so we plan access before the quote.
Maybe, and we’ll tell you before you spend a dollar. Carrollton’s clay soil expands and contracts, and a slab poured decades ago without proper steel or vapor barrier may need reinforcement before it can support a conditioned living space. We assess the slab and give you a written recommendation with a price. Call (903) 342-8977 to start the assessment.
