CA SB1103

Extends rent increase notice requirements to qualified commercial tenants (microenterprises, restaurants with fewer than 10 employees, or nonprofits with fewer than 20 employees), requiring landlords to provide 30 days' notice for increases of 10% or less and 90 days' notice for increases greater than 10%.

Applies language translation requirements (Spanish, Chinese, Tagalog, Vietnamese, or Korean) to commercial leases with qualified commercial tenants effective January 1, 2025, but prohibits the interpreter exemption that applies to residential leases.

Extends non-renewal notice requirements to qualified commercial tenants, requiring landlords to provide 60 days' notice (or 30 days if tenant has occupied the property for less than one year) before terminating a periodic tenancy.

Prohibits landlords from charging qualified commercial tenants fees for building operating costs unless costs are allocated proportionately, documented, and incurred within the previous 18 months or reasonably expected within the next 12 months; allows tenants to raise violations as a defense in eviction actions and recover actual damages plus attorney's fees.

Violations regarding building operating cost fees do not entitle qualified commercial tenants to civil penalties for rent increases, and district attorneys or city attorneys may seek injunctive relief for violations.
