Trusted Garage Conversion Contractor for Austin Homeowners

Garage conversion in Austin typically costs $70,000 to $130,000 for a full permitted living-space conversion, before permit fees, and most projects take 8 to 14 weeks from permit submission to final inspection. Fielding ADU Austin builds garage conversions as our Garage Conversion Contractor in Austin, working under The Garrison Standard, the same written-price and one-year-guarantee discipline that Garrison Partners has used since 2006. If you’re in Austin and want the work priced in writing before any crew shows up, call (361) 309-9568 and we’ll walk you through the numbers for your specific lot.

Call (361) 309-9568

We’re the ADU and garage-conversion arm of the Garrison Partners family. Our crews are background-checked and uniformed. The price you approve on day one is the price on the final invoice, and every project is covered by the 365-Day Done Right Promise: if the work fails inside a year, we come back and make it right at no charge.

Austin’s permitting rules from the Development Services Department treat a garage conversion as a change of occupancy, which means insulation, ventilation, egress, and electrical all get reviewed. We pull permits on every job, schedule the inspections, and don’t call the job done until the inspector signs off.

Garage Conversion Permit

An attached garage converted into living space

A garage conversion permit in Austin is the city’s written approval to change a garage from vehicle storage to conditioned living space, and it’s required any time you add insulation, drywall, electrical, plumbing, or a bedroom. Fielding ADU Austin handles the permit package, the plans, and the inspections for every conversion we build. Permit fees in Austin for a garage conversion typically run $1,500 to $4,000 depending on the scope and the square footage, and plan review adds another layer of time you don’t want to eat alone.

Setback and Occupancy Requirements

Austin code has minimum setback rules, and the Development Services Department can require a written variance if your existing garage already sits close to the property line. We check that before the plans go in so the project doesn’t stall in review.

Why Homeowners Get Stuck

Most permit rejections we correct involve egress windows, ceiling height, or missing HVAC calculations. When we prepare the package ourselves, the back-and-forth with the city is ours to manage, not yours to chase.

Garage Conversion to Living Space

A garage conversion to living space in Austin means turning the existing footprint into a code-compliant, conditioned room with insulation, drywall, flooring, and a proper HVAC connection, and it’s the fastest way to add square footage without adding a foundation. Fielding ADU Austin prices this in writing before work starts, and our typical living-space conversion in Austin runs $70,000 to $110,000 depending on finish level and whether you’re adding a bathroom. You’ll get a line-item quote so you can see exactly where the money goes.

What the Space Needs First

The slab, the roof, and the electrical panel determine most of the budget. We inspect all three before pricing so the quote reflects what’s actually on your lot, not a generic square-foot number.

The Finish Level Decision

Drywall, paint, and LVP flooring get you a clean bonus room. Adding a mini-split, a kitchenette, or a full bath moves the price toward the upper end of the range. We price both paths so you can choose with the numbers in hand.

Garage to Bedroom Conversion

A former garage converted into a guest house

A garage to bedroom conversion in Austin adds a legal sleeping room to your home, and the difference between a bedroom and a bonus room is the code: egress, closet, smoke detection, and heating all have to pass inspection. Fielding ADU Austin builds bedrooms that meet Austin’s specific requirements, and these conversions typically run $65,000 to $95,000 depending on whether the existing garage already has the right window openings. We’ll tell you before we quote whether your garage can host a legal bedroom or whether it’s better as a living space without the sleeping designation.

Egress Is the Gatekeeper

An Austin inspector will look for a window opening large enough for a person to exit, with a sill height no higher than 44 inches. If the existing opening doesn’t qualify, we cut and install the required window as part of the scope.

What a “Bedroom” Adds

A permitted bedroom changes the legal bedroom count on your property record, which matters for appraisal and resale. We build it through the by-the-book process so the room actually counts, not just visually.

Garage Conversion ADU

A garage conversion ADU in Austin is a converted garage that becomes a separate dwelling unit with its own entrance, kitchen, bath, and address, and it’s the most cost-efficient way to add a rentable unit because the walls and roof already exist. Fielding ADU Austin builds ADUs under the same Garrison Standard as our room additions, and a garage conversion ADU in Austin typically runs $90,000 to $150,000 depending on utility access and whether the structure needs structural upgrades. We work with prefab and modular systems, including Abodu and Cover, when the schedule matters, and we build conventionally with James Hardie siding when the job calls for it.

Kitchen and Bath Scope

An ADU needs a full bathroom and a functional kitchen, which means plumbing, drains, and possibly a panel upgrade. We survey the existing service before quoting so the number doesn’t move when the electrician shows up.

Utility Sub-Metering

Austin Energy and Austin Water have rules about separately metering ADUs. We handle the paperwork and the coordination so the unit can be billed independently if you plan to rent it.

Garage Apartment Conversion

A bedroom and desk inside a converted garage

A garage apartment conversion in Austin turns an existing garage into a private apartment, usually above a garage or attached to the main house, with a full bath, a kitchenette or full kitchen, and its own entry. Fielding ADU Austin, your Garage Conversion Contractor in Buda neighbor, builds these for homeowners who want rental income or a long-term setup for family, and the Austin range is $100,000 to $160,000 depending on whether the garage is attached or detached and how much structural work the floor and roof require. The written price we hand you before work starts is the number you’ll see on the final invoice, no change orders slipped in.

Detached vs. Attached Costs

A detached garage apartment needs its own utility trench and often a new electrical sub-panel, which adds cost. An attached conversion can tie into the existing service, keeping the number lower.

Rent-Ready or Simple Finish?

If the apartment will be leased, you’ll want durable surfaces, a full kitchen, and sound separation from the main house. If it’s for family, the same footprint can be finished for less. We quote both levels so the choice is yours, not ours.

Brands We Service

We’ve built garage conversions and ADUs on Tuff Shed-style structures, and we know the framing and foundation options those units need to be permitted as living space in Austin. James Hardie siding is our standard for conventional exterior work because it holds paint longer and stands up to Central Texas heat and humidity, and we install it with the proper rain-screen details Austin inspectors want to see.

For prefab and modular work, we’re fluent with Abodu and Cover platforms and have completed projects where the unit arrived finished and we handled site work, foundations, and utility hookups. Whether you have one of those brands, a Tuff Shed structure, or a conventional site-built garage, we can price the conversion and build it to the Garrison Standard.

Signs You Need a Pro Right Now

  • The garage floor has a crack wider than a quarter inch. That can signal slab movement, and building living space on a moving slab means cracked tile and binding doors later. We inspect before we quote.
  • The garage ceiling height is under 7 feet 6 inches. Austin has minimum ceiling height rules for habitable rooms, and a low ceiling may force a raised-roof or different design approach. Better to know now than after plans are drawn.
  • The electrical panel is original from the 1960s or 1970s. A conversion adds load, and an undersized or outdated panel becomes the surprise line item that wrecks budgets. We check the service size first.
  • You’ve already been quoted by another contractor and the price changed twice. A moving number usually means the estimator never looked at the slab, the panel, or the city’s setback rule. Our written price covers what’s actually on your lot.
  • You want the unit rented before next summer. Permit review and inspections in Austin eat calendar time, and starting late just pushes income out. We sequence the work so inspections aren’t the bottleneck.

Our Process, Step by Step

  1. 1
    Site walk and measurements. We inspect the slab, roof structure, existing wiring, panel capacity, and the distance to the property lines. This is where we find the things that move budgets, and it happens before any price is written.
  2. 2
    Written line-item price. You get a fixed price in writing, including the permit scope, before any work starts. No allowances that balloon later, no “we’ll figure that out when we get there.”
  3. 3
    Permit package and plan review. We prepare the drawings, submit to the Development Services Department, and answer their comments. You don’t have to learn Austin code to get through review.
  4. 4
    Build and inspections. Our background-checked, uniformed crew does the work in sequence, and every inspection is scheduled and tracked. We’re on site, the inspector is on site, the job moves.
  5. 5
    Final walk and written guarantee. Before we call it done, you walk the space with the lead and we fix anything you flag. Then you get the 365-Day Done Right Promise in writing: if it fails inside a year, we return at no charge.

How Much Does Garage Conversion Contractor Cost in Austin?

A typical garage conversion in Austin runs $70,000 to $130,000 before permit fees. A basic conversion to living space, without plumbing, sits at the lower end. A garage conversion ADU with a full bath and kitchen sits at the upper end, and a detached garage apartment with separate metering can go past $150,000. The biggest cost drivers in Austin are the condition of your slab, whether the existing roof structure can carry the ceiling, how far the garage sits from the property line, and whether the panel needs an upgrade.

The way to avoid overpaying is to get a quote that names the slab, the panel, the drainage, and the insulation as line items, not as vague “allowances.” Allowances are how a low quote becomes a high invoice. Our free estimate includes a written price for the full scope, including permit fees as a separate line, so you can compare real numbers.

We don’t bid low to win the job and then escalate. The price Reed Calloway signs off on is the price you pay, and The Garrison Code says it plainly: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year.

Key Takeaways

  • Garage conversions in Austin run $70,000 to $130,000 before permit fees, depending on whether you add a bath, a kitchen, or a separate apartment.
  • Permits are required. Austin’s Development Services Department treats a garage conversion as a change of occupancy, and we handle the entire permit process.
  • The written price holds. You approve the number before work starts, and the final invoice matches it.
  • Every job is guaranteed. The 365-Day Done Right Promise covers workmanship for a full year in writing.
