Understanding the California Commercial Tenant Protection Act

Predatory Real Estate Practices After Wildfires

What Landlords Need to Know About New Real Estate Law Requirements in 2025

Effective January 1, 2025, California’s Commercial Tenant Protection Act (SB 1103) introduces significant changes to real estate law that will impact how commercial landlords structure leases and manage relationships with a new category of protected tenants, qualified commercial tenants.

Who Are Qualified Commercial Tenants?

Under this new statute, a qualified commercial tenant includes:

  • Microenterprises (businesses with five or fewer employees, including the owner)

  • Restaurants with fewer than 10 employees

  • Nonprofits with fewer than 20 employees

To be treated as a qualified commercial tenant, the tenant must provide the landlord with written notice of their status and a self-attestation of their employee count, following the timeline requirements outlined in the law.

Key Real Estate Law Changes for 2025

1. Limitations on Pass-Through Operating Expenses

Landlords face tighter restrictions on billing qualified commercial tenants for operating costs, especially for leases executed or renewed after January 1, 2025. To charge these costs, landlords must:

  • Provide itemized, attested documentation

  • Limit costs to those directly tied to property operation, maintenance, or repair

  • Allocate costs proportionately and transparently

  • Deliver documentation before any recovery of fees

Violations expose landlords to civil liability, including actual and treble damages, attorney’s fees, and even punitive damages if the violation is willful.

2. Lease Translation Requirements

If a lease is negotiated primarily in Spanish, Tagalog, Chinese, Vietnamese, or Korean, landlords must provide a translated copy of the lease before signing. This translation requirement cannot be waived, even if a translator is present, and failure to comply gives the tenant the right to rescind the lease.

3. Rent Increases and Lease Modifications

For short-term leases (month-to-month or less), the law requires:

  • Advance written notice for rent increases, up to 90 days depending on the increase

  • Written notice of any non-rent modifications, with effective dates dependent on the lease term

These protections ensure that tenants have adequate time to respond to changes in their leasing terms.

4. Lease Termination and Renewal Protections

When a lease ends, and the landlord continues to accept rent from a qualified commercial tenant:

  • The lease is deemed renewed on the same terms, for up to one year

  • 30-day notice is required to terminate tenants with less than one year of occupancy

  • 60-day notice is required for tenants occupying for one year or more

These provisions aim to prevent sudden evictions and promote leasing stability for vulnerable small businesses.

Preparing for Compliance

These sweeping updates to real estate law mean landlords must revisit and revise their leasing procedures, cost allocations, and communication strategies. The law is clear: protections for qualified commercial tenants cannot be waived, and failure to comply may result in significant legal consequences.

Before these changes take effect, landlords should:

  • Review existing lease forms

  • Establish internal procedures for handling tenant self-attestations

  • Prepare for multilingual translations, if applicable

  • Adjust billing systems to ensure compliance with cost documentation rules
