Yes, you will almost certainly need a permit to convert a garage into a living space in California. This is a major structural and functional change that must comply with state and local building codes, including the California Building Code (CBC), zoning ordinances, and energy efficiency standards (Title 24). The permit process ensures the work is safe, includes proper egress, electrical, insulation, ventilation, and often addresses parking replacement requirements. You must apply through your city or county's building department. Failing to obtain permits can result in fines, forced reversion of the work, and complications when selling your home.

The 10-year rule for garage conversions is a critical planning principle in the UK. It refers to the legal provision that if a garage conversion has been in continuous use as part of a dwelling for more than ten years without enforcement action from the local planning authority, it may become lawful through a Certificate of Lawful Existing Use or Development (CLEUD). This is not automatic; you must apply for the certificate and provide substantial evidence, such as council tax records or sworn affidavits. It is always safer to obtain proper planning permission or confirm permitted development rights first.
