Landlord-tenant law involves renting or leasing residential and commercial properties. This includes the rights of both the owner and renter, and often involves evictions, also known as unlawful detainers, as well as habitability issues. California law provides a number of protections and requirements for both landlords and tenants in their dealings with each other.
Lawsuits related to security deposits are often brought in small claims court. See our Small Claims Law 101 page for more information.
