Garage conversions are one of the fastest, most affordable paths to additional living space in California. Under state law, cities cannot require replacement parking when you convert a garage to an ADU — that's one of the biggest advantages over new construction. But you still need to meet habitable space standards for ceiling height, natural light, ventilation, and fire separation.
Garage conversions are one of the fastest paths to additional living space in Riverside.
