This law requires that owner's of property run background checks on prospective building manager's. If the manager has been convicted of a serious crime (murder, rape, stalking, etc...) the owner may not hire the manager or must discharge the manager if the manager has already been hired. If the manager was already working as of July 1, 1995, and the owner knows the manager committed a serious crime, the owner must notify all tenants. If the tenant's wish, they have the right to give two weeks notice and quit their lease. A tenant exercising this option is treated as if they had given the proper amount of notice before leaving.
The rule was named after Kari Koskinen, a woman murdered by her building manager. The manager had a previous criminal record that was not disclosed to her.
This rule prohibits landlord's from entering an apartment unless they give proper notice and have a reasonable business reason for entering. Manager's found entering for an illegitimate reason are subject to a $100 fine for each unreasonable entry which is paid to the tenant. The rule also requires manager's or owner's to leave a note informing the tenant they have entered the apartment. The statute contains a list of reasonable reasons to enter an apartment.
