The Ellis Act is a state law (Government Code Section 7060 et. seq.) designed to allow landlords to get “out of the rental business.” In order for Ellis evictions to be approved, landlords must remove all units within a building from the rental market for five years. It cannot be applied to just a single unit.

Landlords can't raise rent more than once a year, and they need to inform tenants in writing 30 days prior to any increase going into effect.
