Relating to a landlord's authority to collect from a tenant certain late fees for nonpayment or late payment for a utility.

SB 603 prohibits landlords from charging tenants late fees for the landlord’s own nonpayment or late payment of utility bills (e.g., electricity or water) that the landlord provides to the tenant under the lease. It directly affects tenants in new leases or renewals signed on or after September 1, 2025. The bill allows landlords to still charge tenants for their own late payments of utility fees owed to the landlord, but not for the landlord’s own utility payment delays. This does not change landlords’ ability to collect standard late fees for rent or other lease obligations.
