Garage Conversions in Chehalis
For garage conversions into bedrooms, offices, family rooms and in-law suites in Chehalis, you deal with Greg directly — no salesman, no middleman. He's based in Rainier, about 20 miles away, with 33 years of experience.
In the river valleys and farm country, a good building site is one that stays dry — set above the low ground, with the water steered away from the foundation before anything goes up. 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.”
What's included
Garage Conversions we do in Chehalis
- 01
Bedrooms and home offices
A finished, heated room with a proper window, a closet if needed, and a door into the house, built to count as real living space.
- 02
Family rooms and home gyms
Open rec rooms, gyms and hobby spaces with durable flooring and enough outlets and lighting for how you will use them.
- 03
Garage-to-ADU conversions
A full living unit with a bathroom and kitchenette for a parent, an adult child or a renter, built to your city or county ADU rules.
- 04
Filling in the garage door
Framing the big opening with a wall, windows or a door, and siding the outside to match so it does not look like a closed-up garage.
- 05
Floor, insulation and heat
A vapor barrier and insulated subfloor over the slab, insulated walls and ceiling, and heat so the room is comfortable in January.
- 06
Plumbing and electrical
New circuits, lighting and outlets, plus drain and water lines for a bathroom or wet bar where the plan calls for one.

Garage Conversions around Chehalis
Greg works all over Chehalis — near Hillside Historic District, Pennsylvania Avenue–West Side Historic District and John Dobson Park and out by McFadden Park and Newaukum Hill — and throughout Lewis County.
Chehalis is the Lewis County seat, just south of Centralia along I-5 and the Chehalis River. Chehalis is about 20 miles southwest 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
How it works
How your Chehalis garage conversion job works
- 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
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
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
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 Chehalis: FAQs
Do you do garage conversions in Chehalis, WA?
Yes. Chehalis is about 20 miles southwest 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 Chehalis?
It depends on the project. When one is needed, Greg pulls the permit from the City of Chehalis's building department and builds to whatever the permit and inspection require.
Where will the car go?
It is worth deciding that first. Some people are happy parking in the driveway, while others pair the conversion with a new detached garage or shop on the same lot, which Greg also builds.
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.
