The cost to convert a garage to an ADU in Los Angeles typically ranges from $120,000 to $250,000 or more. This wide range depends on factors like the garage's existing condition, the complexity of plumbing and electrical work, the quality of finishes, and the specific permitting fees in your neighborhood. A basic conversion with minimal upgrades will be at the lower end, while a high-end, fully permitted ADU with a kitchen, bathroom, and separate utilities will reach the higher figures.

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 conversion process is typically more cost-effective and faster than new construction, as the primary structure already exists. Key considerations include ensuring compliance with local zoning and building codes, which cover aspects like minimum ceiling heights, separate utilities, and proper egress.
