Garage Conversion Contractor in Plano - Plans, Permits & Build, One Fixed Price

Fast, Reliable Garage Conversion Contractor Across Plano

A garage conversion in Plano typically costs $85,000 to $165,000 for a full apartment build-out, and the work takes 10 to 16 weeks from permit submittal to final inspection. The biggest variable is whether your garage is attached or detached, because Plano treats the two differently at the permit counter. If you’re on a 7,500 square foot lot in the Old Towne district or a 1990s cul-de-sac off Independence Parkway, the setback rules that apply to your garage will shape what you can build and what it costs. Lodgewick ADU Dallas coordinates scheduling and dispatch from our Dallas-Fort Worth office, and our crews serve Plano neighborhoods directly.

Garage Apartment Conversion in Plano

A Garage Apartment Conversion in Plano turns an existing garage into a self-contained living unit with its own bathroom, kitchenette, sleeping area, and private entrance. Homeowners in neighborhoods like Oakwood Gardens and Ridgefield typically take this route when they need space for an aging parent or adult child, or when they want rental income from an ADU (accessory dwelling unit, a small independent home on the same lot). A full apartment conversion with plumbing, electrical, insulation, drywall, flooring, and a mini-split HVAC system runs $110,000 to $165,000 in Plano. Attached garage apartments usually come in lower because exterior wall work is limited, while detached conversions carry extra cost for trenching utilities across the yard.

Detached Garage to Apartment

Detached garage apartments in Plano hit a different set of rules than attached conversions. The city requires detached ADUs to meet the same fire separation and setback standards as new accessory structures. If your 1990s-era garage sits three feet from the side property line, that’s a problem before we even draw plans. We scope that early, before you spend money on design.

Attached Garage to Living Space

Converting an attached garage into living space in Plano usually means removing the garage door, framing out the opening to match the home’s exterior, and running HVAC from the main system. Costs run $85,000 to $125,000 depending on whether you’re adding a bathroom and whether the existing slab needs leveling. You keep the roofline, which keeps the look consistent with the rest of the house in places like Hills of Prestonwood.

Garage Conversion Permit in Plano

A Garage Conversion Permit in Plano is required for any conversion that adds living space, and detached conversions that touch the exterior wall typically trigger a full building permit rather than a simple remodel permit. That’s a key difference from neighboring Dallas, where interior-only changes face fewer checks. In Plano, the building department reviews fire separation, setbacks, structural changes, and utility connections as one package. Filing with incomplete drawings adds weeks. We handle permit submittal, coordinate the inspections, and make sure the work passes before we call it done.

Setback and Fire Separation Review

Plano enforces 5-foot side and rear setbacks for detached ADUs. A garage built in the 1990s often sits closer than that, which means a variance or a redesign before the permit is approved. Fire separation between the new living space and the main house also gets reviewed, especially for attached conversions that share a wall. We sequence this early so the schedule doesn’t stall at inspection.

Sewer and Foundation Sequencing

Older Plano slabs, especially in homes built before 2000, often lack a dedicated sewer lateral for a new kitchenette. Tying into the main line usually means cutting through the driveway or patio slab, not a simple interior tie-in. Foundation inspections are also part of the permit process for attached conversions, and any existing slab cracks or settlement issues need to be addressed before framing starts. Leaving these out of the initial estimate is how homeowners get surprised, and we don’t do that.

Trusted Brands We Service in Plano

Our crews work hands-on with leading ADU materials and manufacturers, so we can match a Plano lot to the right system. We regularly specify James Hardie panel siding for detached conversions because it holds up to North Texas heat and humidity cycles. Tuff Shed shells work well for owners who want a faster structural envelope on a level slab. And for homeowners considering a prefab approach, we’re familiar with Plant Prefab’s panelized systems and how they coordinate with Plano’s permit requirements. We don’t push one brand, we spec what fits your lot, budget, and timeline, and we stock common parts locally so a mid-build adjustment doesn’t stall the schedule for two weeks.

Common Garage Conversion Contractor Problems We See in Plano Homes

• Setbacks discovered too late. Plano enforces 5-foot side and rear setbacks for detached ADUs, and many garages built in the 1990s sit closer than that. Starting without confirming the garage’s setback forces a redesign or a variance hearing, adding weeks and thousands in design fees.
• Plumbing scope underestimated. Older Plano slabs lack a dedicated sewer lateral for a kitchenette, so tying into the main line often means cutting through the driveway or patio slab. A contractor who assumes a simple interior tie-in will hit a change order within the first month.
• Prefab shells assumed to be permit-free. Plano treats any shell with a foundation as a structure requiring its own permit, even if it never touches the main house. A Tuff Shed or similar prefab shell used as a conversion base needs its own review and inspection.
• Exterior wall work triggering full review. In Plano, any conversion that touches the exterior wall of a detached garage, even just replacing a roll-up door with panels, can trigger a full building permit rather than a simple remodel permit. Contractors who don’t flag this early leave homeowners exposed at final inspection.
