What is the legal procedure for handling rent increases?

Landlords must provide written notice of rent increases, with the amount of notice varying based on the percentage of the increase and the length of the tenant’s occupancy. For increases of more than 10%, a 90-day notice is generally required, while smaller increases require 30 days’ notice. Rent increases must comply with California’s rent control laws and local ordinances, and tenants should review their lease agreement for specific terms.
