Is a Garage Conversion Right for You?

A garage conversion is one of the most cost-effective ways to add living space. But it is not always the best option. If you still need covered parking or significant storage, a home addition might make more sense. We will walk through your situation honestly and help you decide which route gives you the most value.

We Understand the Hesitation

Converting your garage is a big decision. Here are the concerns we hear most from homeowners, and why they are glad they moved forward.

"I'm worried about losing my parking and storage."

That is the number one concern we hear, and it is valid. We help you think through alternatives like a carport, a small storage shed, or reorganizing other areas of your home. Many clients find they rarely used the garage for parking anyway and the extra living space is far more valuable.

"Will a garage conversion look like a converted garage?"

Not when it is done right. We match flooring, trim, and finishes to the rest of your home. Proper insulation, drywall, and ceiling height adjustments make the space feel like it was always part of the house. Most visitors will not be able to tell it was ever a garage.

"I'm not sure about the permits and zoning."

We handle all of that. Spokane and the surrounding cities have specific rules about garage conversions, ADUs, and setbacks. We know the local codes, pull the permits, and coordinate inspections. You do not need to navigate the bureaucracy on your own.

Garage Conversion FAQs

Common questions from Spokane homeowners about garage conversions and garage remodels.

How much does a garage conversion cost in Spokane?
Garage conversions in Spokane typically range from $12,000 to $60,000 depending on size and scope. A basic single-car conversion with insulation, drywall, and flooring might run $12,000 to $20,000. A full ADU with a bathroom, kitchenette, and separate entrance will be closer to $40,000 to $60,000. We provide detailed quotes so you know exactly what to expect.
Do I need a permit for a garage conversion in Spokane?
Yes. Garage conversions require building permits in Spokane, Spokane Valley, and most surrounding cities. You will need permits for structural changes, electrical, plumbing, and mechanical work. We handle the entire permit process and all inspections for you.
How long does a garage conversion take?
Most garage conversions take 4 to 8 weeks depending on the scope. A straightforward living space conversion is typically on the shorter end. Adding a bathroom, kitchenette, or separate entrance extends the timeline. We will give you a realistic schedule before we start.
Can I convert my garage to a bedroom?
Yes. A garage can become a legal bedroom as long as it meets building code requirements for egress windows, ceiling height, electrical, and smoke detection. We make sure your conversion meets all code requirements so it counts as a legitimate bedroom for resale purposes.
Is a garage conversion better than a home addition?
It depends on your situation. A garage conversion is typically 30-50% less expensive than building a new addition because the foundation, walls, and roof already exist. However, you lose your garage space. If you need both extra living space and covered parking, an addition might be the better investment. We can help you weigh the options.
Will a garage conversion add value to my home?
A well-done garage conversion adds usable square footage to your home, which generally increases value. ADUs and rental units can be especially valuable because they generate rental income. The key is quality workmanship and proper permits. Unpermitted conversions can actually hurt your resale value.
What about parking and storage after converting my garage?
This is something we discuss during the planning phase. Options include adding a carport, building a small storage shed, creating built-in storage within the converted space, or expanding your driveway. Many homeowners find they were not using their garage for parking anyway.
How do you handle insulation and heating in a converted garage?
Garage walls and ceilings are usually uninsulated, and the concrete floor has no thermal break. We install spray foam or batt insulation in the walls and ceiling, add a subfloor with insulation over the slab, and either extend your existing HVAC system or install a ductless mini-split. The result is a space that stays comfortable through Spokane winters and summers.
Can I convert my garage into an ADU or rental unit?
In many cases, yes. Spokane has been updating its ADU regulations to allow more accessory dwelling units. Zoning, lot size, and setback requirements vary by neighborhood. We research the specific rules for your property and handle all permitting. A garage ADU can be a great source of rental income.
Do you do garage conversions in Coeur d'Alene and North Idaho?
Yes. We serve the entire Spokane-Coeur d'Alene metro area including Coeur d'Alene, Post Falls, Hayden, Liberty Lake, and Spokane Valley. We hold contractor licenses in both Washington and Idaho.
