Garage Conversions in Seattle

People in Seattle call Greg for garage conversions into bedrooms, offices, family rooms and in-law suites. He's a licensed, bonded and insured general contractor out of Rainier, about 55 miles away, and every Seattle job starts with a free estimate.

In the older neighborhoods here, a lot of the work is remodels, additions, ADUs and decks on tight lots, built to the city's permit and inspection schedule. Turning it into a real room means dealing with a cold concrete floor, bare walls, the big door opening, and how the new space connects to the rest of the house.

One customer called Greg “a man of integrity.” Another wrote that he “does excellent work.”

Seattle is the biggest city in our service area, about 55 miles north of our base in Rainier. Seattle is about 55 miles north of our base in Rainier, well inside our 100-mile service area.

Western Washington buildings fight water more than anything — months of rain, moss on the roof, rot wherever wood stays wet, and soils that hold moisture. A building lasts when it sits on a proper foundation with drainage around it, is wrapped and flashed right, and is built to dry out.

Ideas for your project

Garage Conversions: what it can look like

  • Single-story ranch house where the former garage is now living space, with lap siding and a window in place of the garage door
  • Garage partway through a conversion, with a new framed and insulated stud wall and a window opening where the garage door used to be
  • Finished room in a converted garage with gray walls, wood-look vinyl floor, recessed lights and a wide window

How it works

How your Seattle garage conversion job works

  1. 1

    Free on-site estimate

    Greg looks at the garage, the slab and how it connects to the house, and gives you a free estimate for the room you have in mind.

  2. 2

    Plan and permits

    We lay out the space and pull the permit, since a conversion changes the use of the room and has to meet code for living space.

  3. 3

    Rough-in and insulation

    We frame the door opening, run plumbing and wiring, insulate, and build up the floor, with inspections before walls close.

  4. 4

    Finish and walkthrough

    Drywall, flooring, trim, doors and fixtures go in, then we clean up and walk the new room with you.

Questions

Garage Conversions in Seattle: FAQs

Do you do garage conversions in Seattle, WA?

Yes. Seattle is about 55 miles north of our base in Rainier, well inside our 100-mile service area. Greg handles garage conversions into bedrooms, offices, family rooms and in-law suites there, and the estimate is free.

Do I need a permit for garage conversions in Seattle?

It depends on the project. When one is needed, Greg pulls the permit from the City of Seattle's building department and builds to whatever the permit and inspection require.

How much does a garage conversion cost?

It depends on what the garage becomes. A simple office or bedroom takes far less work than a conversion with a bathroom and kitchenette, and the condition of the slab and how much insulation and heat the space needs also matter. Greg gives a free on-site estimate once he has seen the garage.

Will a converted garage feel cold and damp?

Not if it is built right. Garage slabs in Western Washington sit on damp ground, so we put a vapor barrier and insulation between you and the concrete, insulate the walls and ceiling, and add heat and ventilation. Done that way, the room stays as dry and warm as the rest of the house.

Do I need a permit to convert a garage?

Yes. Turning a garage into living space is a change of use, so it needs a permit and inspections for framing, insulation, electrical and any plumbing. Greg handles the paperwork and inspections with your city or county.

Can a garage conversion become an ADU?

In many cities and counties around here, yes. Adding a bathroom, a kitchenette and its own entrance can turn the garage into an accessory dwelling unit, as long as the lot meets local rules on parking, size and utilities. Greg will check what your property allows during the estimate.
