Converting a garage into an Accessory Dwelling Unit (ADU) is often a highly worthwhile investment. It provides a significant source of rental income, increases your property's overall value, and offers flexible living space for family members, guests, or a home office. The existing structure typically makes the conversion more cost-effective and faster than a ground-up build. Key considerations include ensuring compliance with local zoning laws, securing proper permits, and investing in professional insulation, plumbing, and electrical work to create a comfortable, legal dwelling.

The 10 year rule for garage conversion typically refers to a local zoning regulation stating that if a garage has not been used for vehicle parking for ten consecutive years, it may be reclassified as legal non-conforming space. This often allows homeowners to convert the structure into living area without needing a variance for lost parking. However, you must provide documented proof, such as utility bills or photos, to show the garage was not used for parking during that period.
