Considerations When Converting Your Garage into a Room

Before starting your garage conversion, it's important to consider key upgrades that will make the space comfortable and functional. From insulation and heating to flooring and windows, these elements can impact both the cost and long-term usability of your converted garage.

Heating and Cooling

Your existing heating, ventilation, and air conditioning (HVAC) system might be able to heat and cool the garage, but not always. An HVAC inspector can help determine if your system can handle the extra space. If not, you can explore options like:

Forced air heater
Floor unit or overhead heater
Infrared heater
Gas or wood burner
Window air conditioning unit
Portable room air conditioner

Plumbing

If your garage conversion includes a bathroom, kitchenette, or laundry area, you’ll need to add plumbing. This can involve extending water supply lines, installing drainage, and making sure the area is adequately ventilated. Plumbing work can add to your costs, especially if your garage is far from existing pipes. Before starting, talk to a plumber to see what’s possible and what permits you might need.

Flooring

Garage floors are usually bare concrete, which isn’t always ideal for a living space. Consider finishing it with one of these options:

Concrete paint kit (epoxy-based) for coating the floor
Resurfacing kits for concrete floors
Acid-staining kits for concrete floors
Garage floor mats
Rubber or vinyl flooring rolls
Engineered wood flooring
Garage floor tiles

Insulation

Adding insulation to the walls, ceiling, and garage door helps keep your new space warm in the winter and cool in the summer. Spray foam, fiberglass batts, or foam board are all good options, depending on your budget.

Windows and Garage Doors

Good insulation isn’t just about the walls – the windows and doors need to be insulated, too. If your garage doesn’t have windows, adding one can bring in natural light. If you're keeping the garage door, an insulation kit can help regulate the temperature.

How Much Does a Garage Conversion Cost?

Converting a garage is often much cheaper than adding an entirely new room to your home. While a full home addition can cost between $20,000 and $80,000, the cost of a garage conversion typically ranges from $6,000 to $24,000, with the average cost around $15,000.

The final price depends on factors like insulation, plumbing, electrical work, and flooring. A simple playroom or office conversion might cost just a few thousand dollars, while a guest suite or rental unit with plumbing and HVAC upgrades can be more expensive.

Before starting, check with your local building department to see if there are any permits or zoning requirements. You might not need one unless you’re adding plumbing or a kitchen, but it’s always good to confirm to avoid unexpected costs.

Do Home Warranties Cover Garage Conversions?

A First American home warranty does not cover garage conversions, but it can cover many of the appliances you purchase for your converted garage, which can help you manage repairs or replacements when they break down.

If you install HVAC, electrical, or plumbing systems in your converted garage, you can also cover those upgrades. Other systems covered by a home warranty include ceiling fans and garage door openers.

With warranty coverage for repair and replacement costs, you can add to the peace of mind that your converted space provides you year-round.

Protect Your New Living Space with a Warranty

A garage conversion is a great way to add space without the high cost of a new construction project. Whether you turn your garage into a living area, office, or gym, you’ll likely need heating, cooling, ventilation, and other systems to keep you comfortable.
