California commercial leases are complex, heavily negotiated documents. While the law treats commercial tenants as sophisticated parties with broad freedom of contract, the Commercial Tenant Protection Act (SB 1103), effective January 1, 2025, has introduced specific protections for "Qualified Commercial Tenants." General lease requirements remain governed by the California Civil Code.
Commercial Lease Fundamentals (Civil Code)
Official Law Citation: General commercial lease structures, including the Statute of Frauds and basic contractual obligations, are governed by the California Civil Code - Leases.
Written vs. Oral Leases
California requires any lease for a term longer than one year to be in writing to be enforceable (Civil Code § 1624). While periodic or month-to-month tenancies can technically be oral, written agreements are standard to ensure all disclosures and terms are legally binding.
Essential Lease Components
Commercial leases must clearly define the following elements to be enforceable and practical:
- Parties and Premises: Full legal names and entity types, with a precise description of the space and common area rights.
- Rent and Escalations: Base rent, lease type (Gross, NNN, etc.), and clear mechanisms for annual increases or index-based escalations.
- Security Deposits: Governed by Civil Code § 1950.7, which focuses on the timeline for returning funds (typically within 30 days) rather than capping the amount.
- Maintenance Allocation: Unlike residential law, there is no implied warranty of habitability; the lease must explicitly state who is responsible for structural vs. non-structural repairs.
- Assignment and Subletting: Consent requirements and "recapture" rights that allow a landlord to terminate if a tenant seeks to transfer the lease.
SB 1103: The Commercial Tenant Protection Act
Effective January 1, 2025, SB 1103 provides enhanced transparency and notice requirements for Qualified Commercial Tenants (QCT). A QCT is generally defined as a microenterprise (fewer than 5 employees), a restaurant with fewer than 10 employees, or a nonprofit with fewer than 20 employees, provided they have submitted a written self-attestation to the landlord.
Rent Increase Notice Periods
For Qualified Commercial Tenants, landlords must provide extended notice for rent adjustments (Civil Code § 827):
- 30 Days' Notice: For rent increases of 10% or less.
- 90 Days' Notice: For rent increases of more than 10%.
Enhanced Termination Notice
Landlords must provide at least 60 days' notice to terminate the lease of a Qualified Commercial Tenant, regardless of conflicting terms in the lease agreement (Civil Code § 1946.1).
Operating Cost Transparency
Landlords are prohibited from charging QCTs for building operating costs unless the costs are proportionately allocated and documented. Landlords must provide an itemized list of costs and supporting documentation upon the tenant's request (Civil Code § 1947.15).
California-Specific Considerations
Prop 65 and ADA Compliance
Leases should clearly allocate responsibility for Proposition 65 warnings regarding chemical exposures and ADA compliance. Under California law, landlords must disclose whether the premises have been inspected by a Certified Access Specialist (CASp).
Earthquake and Seismic Retrofit
Given the regional risk, leases often address:
- Responsibility for seismic retrofit costs (especially in older unreinforced masonry buildings).
- Reconstruction obligations following a casualty event.
- Business interruption insurance requirements.
