A law taking effect Jan. 1 will require landlords to provide an additional month’s notice when they increase the rent on month-to-month tenants by more than 10%. Under AB 1110 by Assemblywoman Laura Friedman, D-Glendale, rental owners and managers will need to provide 90 days’ notice for rent increases that clear the 10% threshold. Until now, a 60-day notice was required.
