Los Angeles Commercial Lease Law: SB 1103 Compliance and Risk Mitigation

Expert Strategic Guidance from Simantob Law Group on the Commercial Tenant Protection Act

As Los Angeles commercial real estate attorneys at Simantob Law Group, we specialize in commercial real estate and finance, offering decades of experience navigating complex negotiations, regulatory compliance, and landlord-tenant disputes.

California’s Commercial Tenant Protection Act (SB 1103)—effective January 1, 2025—imposes new compliance obligations on landlords leasing to small commercial tenants. These rules create significant risks, including litigation exposure, limits on CAM cost recovery, and strict documentation standards.

This blog provides a strategic summary for landlords and property owners seeking to protect their assets and comply with California Civil Code §1950.9 and related statutes.

I. Strategic Risk Management: How to Identify a Qualified Commercial Tenant (QCT)

Compliance with SB 1103 begins with determining whether your tenant qualifies as a Qualified Commercial Tenant (QCT). This designation activates the law’s protections and imposes new obligations on landlords. The requirements apply only when the tenant meets specific size criteria and provides written notice and self-attestation before or at lease signing.

Under the 5/10/20 Rule, a QCT falls into one of three categories:

  • A microenterprise with five or fewer employees, including the owner.
  • A restaurant with fewer than ten employees.
  • A nonprofit organization with fewer than twenty employees.

If the tenant meets these thresholds and submits the required attestation, SB 1103 protections are triggered. Without this attestation, the law generally does not apply—but landlords should never assume. Verification is essential to avoid compliance risks.

Legal Strategy for Landlords

To mitigate risk, we recommend adding a QCT Representation and Warranty Clause to your lease. This clause confirms the tenant’s status and provides indemnification if the representation proves inaccurate. For example:

“Tenant represents and warrants that, as of the execution date of this Lease, Tenant is not a Qualified Commercial Tenant as defined under California Civil Code §1950.9. Tenant shall indemnify and hold Landlord harmless from any expense arising from a breach of this representation.”

II. Zero-Tolerance Compliance: Mandatory Lease Disclosures Under SB 1103

California’s SB 1103 imposes strict disclosure requirements on landlords leasing to QCTs. These disclosures are non-negotiable, and failure to include any one of them can create grounds for legal challenge.

CASp Accessibility Disclosure (Civil Code §1938)

Every commercial lease must include a notice informing tenants of their right to request an inspection by a Certified Access Specialist (CASp) to determine whether the premises comply with California’s construction-related accessibility standards. The statutory language must appear in full within the lease.

SB 1103 Operating Cost Notice (Civil Code §1950.9)

Before executing a lease with a QCT, landlords must provide written notice explaining the tenant’s right to inspect supporting documentation for building operating costs. This disclosure is critical because failure to deliver it can jeopardize the landlord’s ability to recover CAM fees. If a QCT submits a written request, the landlord has 30 days to provide itemized invoices, a proportional allocation tabulation, and a signed attestation confirming accuracy.

Lease Translation Requirement (Civil Code §1632)

If lease negotiations occur primarily in Spanish, Chinese, Tagalog, Vietnamese, or Korean, the landlord must provide a written translation before signing. Failure to comply grants the QCT a non-waivable right to rescind the lease, creating significant financial exposure.

III. Non-Waivable Protections and Enforcement Risk Under SB 1103

One of the most critical compliance points in SB 1103 is that the protections granted to a QCT under Civil Code §1950.9cannot be waived. Any lease clause attempting to limit or remove these rights is void as a matter of public policy.

Protecting Revenue Through CAM Fee Documentation

Recovering Common Area Maintenance (CAM) fees from a QCT now requires more than standard accounting—it demands a legal defense mechanism built into your property management process. SB 1103 sets strict documentation standards that landlords must meet to avoid disputes and penalties.

The Attested Documentation Standard

If a QCT requests supporting documentation, the landlord has a 30-day deadline to provide all required elements:

  • Allocation Tabulation: A clear breakdown showing how operating costs are proportionately allocated among tenants.
  • Itemized Documentation: Valid quotes, invoices, or receipts for each expense.
  • Landlord Attestation: A signed and dated statement by the landlord or authorized agent certifying that the documentation is accurate and complete.

Why Accuracy Matters

This attestation is more than a formality—it is the point of verification that protects landlords from claims that could be used as an affirmative defense in an Unlawful Detainer action. Failure to comply can halt eviction proceedings and expose landlords to statutory penalties, including treble damages for willful violations.

IV. Summary of New Regulatory Controls Under SB 1103

California’s SB 1103 introduces several critical compliance requirements that every landlord must implement before January 1, 2025. These rules affect security deposits, rent increase notices, termination timelines, and the timing of operating cost recovery.

Security Deposit Cap

Security deposits are now capped at one month’s rent plus the first month’s rent.

Rent Increase Notice

Rent increases exceeding ten percent require 90 days’ notice when leasing to a QCT.

Termination Notice

Termination of a QCT tenancy after one year requires at least 60 days’ notice.

Cost Timing

Operating costs billed to QCTs must fall within a strict timeframe: expenses must have been incurred within the previous 18 months or be reasonably projected for the next 12 months. These rules ensure transparency and prevent landlords from passing through outdated or speculative charges.
