  • Sustainable Living: This option contributes to sustainable housing solutions by maximizing space usage.

Legal Considerations for Converting a Garage into an ADU

Zoning Regulations

Before proceeding with your project, it’s crucial to check local zoning regulations regarding ADUs. Different areas have various rules, including size, height, and occupancy limits. Contact your local zoning office or visit their website for detailed information.
