Properties containing three or more rental housing units at the time of sale must provide notice to all tenants and the City that a transfer of ownership has occurred. Once notice is provided, a three-month "tenant notification period" begins. During the 90-day period, the new owner may be required to pay relocation benefits to a tenant if the owner issues a non-renewal without cause or non-renewal due to rescreening. The new owner could also be subject to paying relocation assistance if they increase the rent, re-screen existing residents, or implement a material change to the lease resulting in a tenant giving the notice to terminate their lease.
