A garage conversion in Richardson typically costs $85,000 to $160,000 for an attached conversion and $110,000 to $210,000 for a detached ADU with a kitchen, and most projects run 14 to 20 weeks from permit to final inspection. If you’ve got a two-car garage off Arapaho Road that’s become a storage locker, or a detached structure behind a 1960s ranch near Cottonwood Creek Trail that’s only holding old bikes, you’re leaving real square footage on the table. Our Garage Conversion Contractor team works in Richardson neighborhoods every week, from Canyon Creek to Heights Park to Reservation, and we know what these houses need before we ever walk the lot. Call (361) 204-4652 for a written estimate that includes every permit, inspection, and line item.
Why Lodgewick ADU Dallas Is Richardson’s Preferred Garage Conversion Contractor Company
Russ Delmar leads our Richardson work, and he’s been managing garage conversions under the Kingswell banner since 2010. Russ and the crew know that Richardson’s housing stock skews mid-century: slab foundations, brick veneer, attached garages sized for two 1960s sedans, and detached garages that were often built with no insulation and minimal electrical. That matters because a garage slab from 1965 behaves very differently than one poured last year. We plan for what we’re going to find, not what we hope to find.
Richardson homeowners call us because the price we write is the price they pay. No change orders at the door. That’s The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every project. If something isn’t right within 365 days, we come back and make it right. No arguing, no “that’s not covered” runaround. It’s in writing on every contract.
When you call (361) 204-4652, a live person answers. Always. Scheduling and dispatch are coordinated from our Dallas-Fort Worth office, and our background-checked crews serve Richardson locally. Russ carries a working knowledge of Richardson’s permitting process and zoning code, including the specific rules around garage conversions that trip up plenty of first-time ADU owners. You’ll get straight answers about your specific street, not generic talk about “garage transformations.”
Garage to Bedroom Conversion in Richardson
A Garage to Bedroom Conversion in Richardson is the most common project we do: taking an attached garage and turning it into a proper bedroom, often with an en-suite bathroom, for an aging parent, a returning adult child, or a growing family that doesn’t want to leave the school district. The work involves insulating and leveling the existing slab, reframing the garage door opening, running new electrical and HVAC, and matching the exterior so it doesn’t look like a garage anymore. Richardson’s zoning treats attached garage conversions differently than detached ones, which makes this the faster and more affordable route for most homeowners.
Attached Garage to Bedroom Scope
An attached garage to bedroom conversion in Richardson runs $85,000 to $130,000 depending on whether you’re adding a bathroom. The garage already shares a wall with the house, so plumbing and electrical have a shorter run, and the roof structure is already tied in. We still need to bring the slab up to living-space code, which usually means grinding, sealing, and adding a moisture barrier before flooring goes down.
One thing Richardson homeowners don’t expect: your attached garage conversion doesn’t trigger the city’s additional off-street parking requirement. That’s a significant cost and space saver compared to detached projects. We’ve done several attached garage-to-bedroom conversions in the Arapaho Road corridor where the homeowner kept the driveway footprint exactly as it was and still passed inspection.
What the Permit Process Looks Like
Richardson requires a building permit for any garage conversion that changes the use from parking to living space. The plan review looks at insulation values, egress windows, electrical load, and how the new room ties into the existing HVAC. Our team handles the drawings, the submittal, and all communication with the city. We pull the permit; we pass the inspection. If a correction notice comes back, we fix it before we call you.
Garage Conversion ADU in Richardson
A Garage Conversion ADU in Richardson means converting a garage, attached or detached, into a self-contained accessory dwelling unit: its own kitchen, bath, sleeping area, and separate entrance. This is where Richardson’s zoning code gets specific. If the garage is attached, you’re generally converting existing square footage, and the parking requirement doesn’t kick in. If the garage is detached, the city requires one additional off-streight parking space on the lot to offset the parking you’re removing. That means a parking pad, an extended driveway, or a designated gravel space. It’s not optional, and it’s not something you can skip and hope no one notices. Richardson code enforcement responds when neighbors call.
We build detached garage ADUs in Richardson for $145,000 to $210,000 depending on whether you choose a prefab ADU from a manufacturer like Plant Prefab or Abodu, or a site-built structure. Prefab can shave weeks off the calendar, but site-built gives you more control over ceiling heights, window placement, and exterior finish to match your existing house. Russ walks every Richardson customer through both cost structures before you commit to anything.
Detached Garage to ADU: What Changes the Price
Detached garage conversions in Richardson cost more than attached for three reasons: you’re adding a full kitchen and bathroom, you’re running new utility lines from the main house across the yard, and you’re paying for the additional parking space the city requires. A 1960s detached garage slab usually needs full replacement or significant reinforcement before it can carry living load, and that’s a $15,000 to $25,000 line item many homeowners don’t see coming. We put it in the written estimate from day one.
A site-built detached ADU with James Hardie siding to match the main house will run higher than a panelized prefab kit, but it looks like it belongs on the lot. For a 1960s ranch in Canyon Creek, that matters. The house has a certain rhythm to it, and a prefab box can look like an afterthought if it’s not detailed correctly. We’ve done both, and we’ll tell you plainly which makes sense for your lot.
Working with Prefab Manufacturers
Lodgewick has hands-on familiarity with leading ADU manufacturers including Plant Prefab, Abodu, Cover, and others. When a Richardson homeowner wants a faster path to occupancy, we coordinate directly with the manufacturer on foundation specs, utility stub-outs, and site prep. We’ve also spec’d Tuff Shed structures for simple garage-to-studio conversions where the budget is tighter and the use is a home office or workout room rather than a full ADU. Russ will match the manufacturer to your lot, your budget, and your timeline, not the other way around.
Trusted Brands We Service in Richardson
Richardson homeowners ask us about prefab ADU brands constantly, and we work regularly with Plant Prefab, Abodu, and Tuff Shed. We also carry a strong working relationship with James Hardie for siding and trim that holds up to North Texas heat and hail. When a Richardson customer wants a Hardie plank exterior to match their existing brick and siding, we can set the material order within days, not weeks. We don’t stock parts in a warehouse; we order per project and coordinate delivery with the crew schedule so materials aren’t sitting in your driveway for a month. If you’re considering a specific prefab manufacturer, call (361) 204-4652 and someone on our team can tell you what’s realistic for Richardson’s lot sizes and zoning envelope.
Common Garage Conversion Contractor Problems We See in Richardson Homes
- Unpermitted conversions that can’t be sold or refinanced. We’ve walked into garages in Richardson that were converted to bedrooms or studios years ago with no permit, no inspection, and no insulation in the walls. When a neighbor complains about the new ADU’s exterior appearance or parking changes, Richardson code enforcement responds, and the homeowner is stuck with a mess to unwind.
- 1950s-1970s slab problems. Richardson’s mid-century garages were built as parking pads, not living space. The slab is often thin, uninsulated, and not sealed against ground moisture. Attached conversions need a moisture barrier before flooring; detached conversions usually need a full slab replacement. We include this cost in our written estimate from the start.
- Detached parking mistakes. Homeowners convert a detached garage to an ADU, skip the additional parking space, and then Richardson’s zoning enforcement makes them stop work. The parking requirement for detached garage conversions is not negotiable. We design around it from the first site visit.
- Electrical panels that can’t handle the new load. A 1960s-era house in Richardson often has a 100-amp panel, and a garage ADU with a kitchen, mini-split HVAC, and laundry needs real power. We’ll spec a subpanel or a full panel upgrade in the written estimate. It’s not a surprise add-on later.
Pricing for Garage Conversion Contractor in Richardson, TX
Here’s what Richardson homeowners should expect to pay in 2026. An attached garage to bedroom conversion runs $85,000 to $130,000. An attached garage to full ADU with kitchen and bath runs $125,000 to $165,000. A detached garage to ADU runs $145,000 to $210,000 including the additional parking space Richardson’s zoning requires. A simple garage-to-studio conversion, no kitchen, utility room only, can come in around $70,000 to $90,000.
What moves the price in Richardson specifically: the age of your slab, whether you need a new panel, the distance from your detached garage to the main house’s utility lines, and whether you choose prefab or site-built. Mid-century homes near Cottonwood Creek Trail often need more concrete work than newer builds in Canyon Creek. The written estimate you get from us includes all of it. Call (361) 204-4652 and we’ll walk your lot, take measurements, and hand you a line-item price before you commit to anything.

FAQs About Garage Conversion Contractor in Richardson
Yes. Richardson requires a building permit for any garage conversion that changes the use from parking to living space, whether you’re adding a bedroom, a bathroom, or a full ADU with a kitchen. The permit triggers plan review, inspections, and a final certificate of occupancy. Doing the work without a permit creates real problems when you sell, refinance, or when a neighbor files a complaint with code enforcement. We handle the entire permit process, including drawings, submittal, and inspection scheduling. Call (361) 204-4652 and we’ll tell you exactly what applies to your specific street.
Yes, Richardson’s zoning code requires one additional off-street parking space on the lot when a detached garage is converted to living space and the garage is removed as parking. This can be a parking pad, an extended driveway, or a designated space on the existing driveway if it meets dimensional requirements. Attached garage conversions do not trigger this requirement. We design the parking solution into the project from the first site visit, and we make sure it meets Richardson’s standards before we pull the permit. Call (361) 204-4652 if you want to know whether your lot already qualifies.
The biggest cost drivers are the age and condition of your garage slab, whether you’re adding a kitchen (which means plumbing, gas or electric cooking, and ventilation), the distance from detached garages to the main house’s utility lines, and whether you need an electrical panel upgrade. Richardson homes built in the 1950s through 1970s often have thin uninsulated slabs and 100-amp panels, both of which need work before living space can be approved. A realistic attached conversion in Richardson runs $85,000 to $165,000; a detached ADU runs $145,000 to $210,000. Get exact numbers on your project by calling (361) 204-4652 for a free written estimate.
A typical attached garage to bedroom conversion in Richardson takes 10 to 14 weeks from permit submittal to final inspection. A detached garage ADU with a kitchen takes 16 to 20 weeks. Richardson’s permit review is usually two to four weeks, and inspections are scheduled quickly once work is ready. Prefab ADUs from manufacturers like Plant Prefab or Abodu can shorten the timeline by several weeks because the modules arrive already built, but site prep and foundation work still follow the same city schedule. We’ll give you a week-by-week calendar before we start so you know exactly when inspections will happen.
You can absolutely convert your garage into a full ADU with a kitchen, bathroom, and separate entrance in Richardson. Richardson’s zoning code allows both attached and detached ADUs as a residential use, with the attached/detached distinction affecting parking requirements, not the type of living space you can build. A full ADU with a kitchen costs substantially more than a bedroom conversion because of plumbing, ventilation, and electrical requirements, but it’s completely permitted. Call (361) 204-4652 and Russ can walk you through what a full ADU looks like on your specific lot.
