1. Assess Feasibility
Start by evaluating your garage’s condition and layout. Check if the foundation is stable and if the structure is suitable for residential use. Make sure the space meets the minimum size and ceiling height requirements for habitable rooms, which are typically at least 70 square feet and 7 feet high. Confirm that your garage can be connected to utilities such as water, sewer, and electricity.
2. Obtain Necessary Permits
You must apply for the required permits before beginning construction. This process includes submitting plans for review and getting approvals for building, electrical, and plumbing work. If you plan to rent out your backyard dwelling, you may need additional permits and must follow stricter regulations. Some cities also require you to provide off-street parking or comply with visitability ordinances.
3. Design Your Backyard Dwelling
Work with an architect or designer to create a functional layout. Include a kitchen, bathroom, living area, and sleeping space to make the backyard dwelling self-sufficient. Maximize natural light by adding windows or skylights. Choose energy-efficient appliances and fixtures to reduce utility costs. Consider accessibility features if the dwelling will be used by elderly family members or people with disabilities.
4. Budget for Construction
Garage conversions are often more affordable than building a new structure from scratch. However, you should still plan for costs such as structural upgrades, insulation, drywall, plumbing, electrical work, and interior finishes. Like building a backyard home, garage conversions range from from $20,000 to $70,000 or more, depending on size, location, and level of finish. Factor in permit fees, utility connections, and landscaping when creating your budget.
