Comprehensive Guide to Two-Car Garage Specs

A two-car garage gives you secure parking, storage and room for a workspace. Here's what to plan for, from size and doors to flooring, power and permits.

Size and Layout

Standard two-car garages range from about 20 × 20 feet to 24 × 24 feet (6 × 6 m to 7.3 × 7.3 m). Go bigger if you drive a truck or large SUV, want a workshop or need lots of storage. Match the roof, siding and windows to your house, and plan storage, workbenches and walkways from the start.

Garage Door Options

• One double door: 16 × 7 feet is the most common size; 16 × 8 or 18 × 7 suits taller or wider vehicles. Cleaner look and one opener.
• Two single doors: two 8 × 7 or 9 × 7 doors. Easier to park, and if one door or opener fails, you can still use the other.

Choose insulated doors for an attached or heated garage.

Flooring

Concrete is durable and cost-effective. An epoxy coating resists stains, cracks and wear and is easy to clean. Seal or coat it early, and repair cracks before they spread.

Roof and Ceiling

Roofing ranges from asphalt shingles to longer-lasting metal. A higher ceiling adds overhead storage and leaves room for a high-lift door or a wall-mount opener. Ceiling finishes affect insulation, sound and how bright the space feels.

Interior Design

Cabinets, wall-mounted tool racks and a comfortable work area make the garage far more useful. Good, even lighting and a bit of colour can turn it into a space you enjoy using.

Electrical and Plumbing

Plan enough outlets, a dedicated circuit for power tools or an EV charger, and good lighting. Use a licensed electrician. A plumber can add a utility sink, a washroom or even a pet-washing station.

Insulation and Heating

Insulated walls, ceiling and door keep the space comfortable. Heating options range from a space heater to a ductless mini-split heat pump or radiant floor heating, depending on how you use the garage.

Smart Technology

A smart garage door opener, smart lighting and a Wi-Fi thermostat can all be controlled from your phone. Cameras, motion lights and smart locks add security.

Permits and Zoning

Check your municipality's zoning bylaws and the BC Building Code, and get a building permit before you start. Rules cover size, setbacks, height and how the space can be used.

Budget and Building

Build a detailed budget for materials, labour, permits and finishes, plus a contingency for surprises. DIY can save money on simple finishing work, but structural, electrical and door installation work should be done by licensed professionals to make sure it's safe and up to code.
