How to Extend Your Garage

How can I extend my one-car garage?

Lengthen your garage to create a larger workspace. Does your garage tend to double as a home workshop? When you lengthen your garage, you create a lot more room for your tools and equipment. This type of extension can also provide more storage space, or help convert your garage into another living space. For instance, you might lengthen your garage to make room for a home gym.

Widen your garage to fit more cars. Parking space is essential to any home, especially if you’re getting a new car. Transform your one-car garage into a two-car garage, or widen your garage slightly to give your car a little more room. A small extension can help if you store bikes and other outdoor equipment in your garage.

Raise your garage height to fit bigger vehicles. A typical garage is great for basic vehicles, like sedans and SUVs, but likely won’t be tall enough for a trailer or RV. A taller garage can also fit a car lift, which makes working on your vehicles much easier. Garage height extensions are great if you don’t have enough space to extend in other directions.

Can I build an addition on top of my garage?

You can, but it requires a lot of construction and planning. First, you’ll need to hire an engineer to inspect your current garage—they’ll let you know if the frame and foundation can support an extra extension. Then, ask a contractor to inspect and reinforce the garage’s foundation if needed. At this point, hire building professionals to complete the renovations, who can make sure the addition is up to code. For instance, your base garage needs a ⁄8 in (1.6 cm) layer of drywall added along the walls and ceilings when an addition gets installed.

Can I turn my garage into extra living space?

Yes, you can definitely transform your garage into more living space. You might turn your garage into a studio apartment, or convert it into a home gym. Other people turn their garages into home offices, playrooms, or kitchen extensions. You could also turn your garage into a crafting space or laid-back rec area.

Do I need a permit to extend my garage?

You’ll probably need a permit, but it depends on where you live. Meet with a local government employee to see what specific permits you’ll need—different cities, states, provinces, and countries each have unique zoning requirements. Schedule an appointment at your local government office; when you meet, let them know what kind of project you’re planning. They’ll tell you what type of zoning or building permits you’ll need, and give you specific applications to fill out.

How close to my property line can I build an extension?

Ask your county or local government for specifics. Zoning requirements aren’t universal, and your project requirements will definitely depend on where you live. Stop by your local government office—an employee there can let you know what is and isn’t allowed. In Fremont, California, you can extend your home up to 10 ft (3.0 m) from the back property line, as long as your expansion doesn’t take up more than 30% of the backyard.

Can I extend my garage by myself?

You technically can, but it’s not a great idea. Unless you have a lot of contracting experience, you’re better off hiring a professional. Garage extensions require a lot of construction and engineering expertise. To be safe, hire professional contractors to get the job done.

The extension will cost more if you hire construction specialists.
