What Is a Garage Conversion?

Garages are one of the most underused spaces in a home. Converting your garage into a functional living space can help you get the most out of this overlooked diamond in the rough while boosting your home’s resale value. A converted garage can also serve as a steady income source if you decide to rent it out. 

Whether you’re working from home and need a quiet office away from the kids or you’ve always wanted a game room or man cave, a great contractor can help bring your vision to life. A bad contractor, on the other hand, can leave you with a mess.

This is where GreatBuildz comes in.

Our free service connects you with reputable, vetted contractors who have impressive portfolios to boot. Don’t take chances with your project—let our team help you find an outstanding contractor.

Types of Garage Conversions

Garages come in two varieties: attached and detached.

Attached garages are connected to the main house by at least one wall. Detached garages are standalone structures. You’ll need a building permit to convert one into a living space. The good news is that California has relaxed its rules on garage conversions in response to soaring home prices and land scarcity—and that means fewer restrictions for your project.

Your options for converting a garage are limited only by your imagination. Here are some of the most popular choices:

  • Guest room/mother-in-law unit
  • Man cave or game room
  • Home gym/weight room
  • Kids’ room/teen hang out
  • Hobby room or space for collectibles
  • Home cinema

If you’re ready to turn your garage into a functional living space, all you need now is the right contractor. Let GreatBuildz connect you with a garage conversion expert in Los Angeles.

Garage Conversion Contractor Planning

Planning Your Garage Conversion

Converting your garage into a livable space is almost always quicker and less expensive than adding a room or building an accessory dwelling unit, since you’re dealing with an existing structure. Still, it’s a big project, and you want to have your ducks in a row before taking the plunge. These tips will help you avoid common renovation pitfalls.


Map out a plan. Do you want a self-contained guest house with a kitchen and bathroom, or will your converted garage simply be an extension of the main house? Jot down all your project must-haves and give the list to any contractors you’re considering. This way every estimate will be based on the same factors.


Determine your budget. Not mapping out a budget is the quickest way to cost overruns. Take some time to research how much other homeowners in your area paid for similar garage conversion projects. This will help you come up with a realistic budget.


Get three estimates. Reach out to at least three general contractors for estimates and ask to see portfolios of similar projects contractors have completed in your area.


Never pay more than a small deposit. In California, contractors can’t legally ask for more than a $1,000 deposit. If a contractor asks for more, they are violating the law.


Don’t be afraid to walk away. Just because a contractor shows up in a fancy truck or presents you with impressive-looking brochures doesn’t mean they’re the right company for the job. Watch out for red flags—like contractors who don’t return calls or who use aggressive sales tactics. If you feel uncomfortable, go with your gut and move on.
