Prepare the garage for conversion by leveling the floor, ensuring it can support the weight of a living space. Install appropriate insulation in the walls, ceiling, and floor to control temperature and noise. This might involve adding a layer of drywall or using specialized insulation materials.

Strengthen the garage door opening to serve as an exterior entrance or window, and add a secure door and frame. Framing in walls and installing drywall will create room divisions, privacy, and a finished look.

Mechanical and Electrical Work

Update electrical wiring to meet code requirements and support your apartment's needed power. Consult a licensed electrician if you're unsure about DIY work. Install proper heating and cooling systems, such as wall or ceiling units, or ductwork connected to your main home's HVAC system.

Plumbing may require the most extensive work, depending on your desired amenities. If including a bathroom, install proper drainage and plumbed utilities. For kitchenettes or laundries, consider installing sink and utility hookups. Consult a professional plumber if needed.
