Reasons to remodel your garage

Converting a garage is one of the most cost-effective ways to add livable square footage in Seattle — without expanding your home's footprint or going through new construction permitting. A finished garage conversion typically adds 200–600 sq ft of usable space depending on your garage size, and can serve as a rental unit, guest suite, home office, gym or full ADU with a separate entrance.

In Seattle's market, where cost per square foot is among the highest in the country, this kind of conversion pays back at resale and can generate rental income in the short term.

Maksymov Brownstone handles garage conversions from initial design through final inspection. Our in-house team manages structural modifications, insulation to Washington State energy code R-values, electrical and plumbing rough-in, egress windows where required, HVAC integration and all finish work.

We pull permits through the Seattle Department of Construction & Inspections and coordinate inspections — homeowners don't need to manage any of that separately. Whether you're converting a single-car garage into a studio ADU or a two-car garage into a full guest suite with a bathroom, we build to code and on schedule.

What's included in a Maksymov Brownstone garage conversion

Every garage conversion project includes a full site assessment, permit application and design development tailored to your goals and the structural conditions of your garage. We handle framing, insulation, drywall, flooring, electrical panel upgrades where needed, and all finish work.

If the conversion includes a bathroom or kitchenette, we manage plumbing rough-in as part of the same contract. Seattle's single-car garages typically run 200–250 sq ft — our team specializes in small-footprint layouts that maximize usable space without compromising livability.

Common garage conversion types we complete in the Seattle area: studio or one-bedroom ADU with separate entrance, home office with soundproofing and dedicated electrical circuits, guest suite with full or half bathroom, home gym with reinforced flooring and ventilation, rental unit with kitchen and laundry hookups.

Each project is permitted, inspected and delivered with full documentation. Explore our portfolio to see completed garage conversion and ADU projects across Seattle and the Eastside.

Converting a garage adds livable square footage without expanding your home's footprint, which in Seattle's market translates directly to higher property value.

It's also significantly less expensive than a home addition or new construction and typically requires a shorter permitting timeline.
