How to Convert Garage Into a Room (Requirements & Ideas)


You may have been thinking about converting your whole garage or part of it for some other use than just storing some stuff and cars there. Let’s look at some options.

The problem with most garages is that they are unfinished or uninsulatedAnd depending on your region, those can be a big problem if temperatures vary wildly in your garage. And if you want to turn your garage into a usable living space for the whole year.

You have to insulate and finish your garage walls and floors and, in some cases, attic and lower the inner roof. Then there are building codes depending on the usage you are planning.

But most of these garage conversion options don’t require all of that. It’s more about how you prefer to use the space and what really is needed.

Do consider the air quality in the garage too. Good ventilation is an essential minimum, and not storing some things that emit strong odors that can be unhealthy to inhale.

Converting Your Garage Can Add a Lot of Enjoyment to Your Home.

The first things to do in any case is:

Convert Garage to Living Space

Properly converting the garage to an entirely usable living space is not fast or cheap. Using experts can cost tens of thousands of dollars and take weeks.

You need to add insulation, finish the walls and floors, and add heating or cooling. Add windows, doors and upgrade the electrical system. You should also consider the legal and zoning issues. Turning space meant for vehicles for habitable, safe, and conditioned living rooms involves significant legal transformation.

A transformed garage needs to meet the technical requirement and building codes in most municipalities. A range of permits may be required if erecting or moving walls, running water supply or drainage or sewer line.

Some codes govern ventilation, insulation, light, floor covering, and minimum room size.

If you are adding a bathroom or shower, hire an architect to conduct a feasibility study.

You may have to raise the floor or at least install floor covering. Popular options are laminate, tile, wood, and vinyl plank.

Basic Requirements

  • The ceiling must be at least at a minimum of 7 ½ feet height. Take it into account if you need to raise the floor.
  • Natural ventilation that is at least 1/20 the size of the floor space or 5 square feet at a minimum.
  • Heat should be maintained at least 70 degrees F or 21C. for at least 3 feet above the floor.
  • Sleeping areas need a window that is no more than 44 inches off the ground. Also, has an opening of at least 5.7 square feet.
  • Outlets need to be changed to meet the minimal spacing standard requiring no cords to reach farther than 6 feet from an outlet.
  • A room used for sleeping cannot have a garage open into the room.
  • Windows should provide enough natural light. In some municipalities, this means 5 ½ square feet or a percentage of the total garage space.
  • Light. Electrical codes already require garages to have one light switch.
  • All rooms need a smoke detection device installed.
  • The room cannot have a gas water heater in it if it is a sleeping space.

Check with your local housing, permits, and building departments to see what is needed and whether or not you can turn a garage into a living space.

The good news is converting a garage is cheaper and faster than building an addition to your home or buying a new home. If you have a detached garage, even better. You won’t be annoyed by the work being done.

If you have an attached garage, you can consider taking the wall down between your garage and home to create a larger space. Consider also adding second story above the garage.
