Non-qualifying tenants still have four years under CCP § 337 to recover overcharges. A Los Angeles retail tenant in our worked example recovered $4,852 per year in management fee overcharges alone.
California CAM audit window: Under Cal. Civ. Code § 1950.9, qualifying California commercial tenants (QCTs) can demand operating cost documentation with a 30-day response deadline. All other California tenants have 4 years under CCP § 337 for written contract claims.

California SB 1103, effective January 1, 2025, created the first statutory documentation rights for certain small commercial tenants related to building operating costs. For qualifying tenants, the law creates a 30-day deadline for landlords to respond to written requests for operating cost records, prohibits charging operating cost fees before documentation is provided, and creates affirmative defenses and damages remedies when landlords fail to comply.

"California's SB 1103 created the first statutory documentation rights for small commercial tenants. I built CAMAudit to handle both the statutory framework for qualifying tenants and the four-year contract law window for everyone else. California tenants sitting on unreviewed reconciliations should act before the four-year clock runs out." — Angel Campa, Founder of CAMAudit
SB 1103's operating cost protections apply only to "qualified commercial tenants" (QCTs) as defined in California Civil Code § 1950.9. A tenant qualifies as a QCT if they meet one of three size criteria and provide the landlord with written notice of their QCT status:
Size criteria (meet one):
Notice requirement: Tenants must provide the landlord a written self-attestation of QCT status within the prior 12 months (and annually thereafter, and upon lease execution or renewal).
Notably, the statute does not use square footage or rental rate as qualifying criteria. Premises size is not a factor in determining QCT status, according to practitioner analysis of the statute's framework.
If you are a qualifying small business, restaurant, or nonprofit that has not provided this attestation, you are not receiving the statute's protections even though you might otherwise qualify. Notice is not automatic.
For QCTs, California Civil Code § 1950.9 creates the following specific requirements:
Cal. Civ. Code § 1950.9: A landlord may not charge a qualified commercial tenant a fee to recover "building operating costs" unless the conditions specified in this section are met.
Proportionate allocation: Fees must be based on proportionate allocation, not arbitrary amounts.
Timing: Costs included in the fee must have been incurred within the previous 18 months or reasonably expected within the next 12 months.
Pre-execution notice: Before the lease is executed, the landlord must notify the QCT that costs may be inspected.
30-day documentation deadline: Landlords must provide supporting documentation within 30 days of a QCT's written request.
No charge until documentation is provided: A landlord may not charge the fee until supporting documentation is provided.
No unilateral formula changes: Landlords may not change the allocation method or formula in a way that increases the QCT's share without providing written notice and supporting documentation explaining the basis for the change.
For qualifying tenants, § 1950.9 functions as a statutory CAM audit right, but one tied to the broader concept of "building operating costs," not specifically to the CAM label in the lease. In practice:
Compared to the typical negotiated audit rights clause, which usually requires the tenant to initiate an audit (not just request documentation) and allows 30 to 60 days for the landlord to schedule a records inspection, the statutory right is simpler: request documentation, wait 30 days.
One limitation: § 1950.9 applies to "building operating costs" as a pass-through fee structure. If your lease structures CAM differently, for example as a rent component rather than a separately billed fee, the analysis under § 1950.9 may differ. California courts have not yet developed extensive case law interpreting the scope of "building operating costs" under the new statute.
While § 1950.9 is the most directly CAM-relevant protection, SB 1103 also enacted or expanded several other protections:
Civil Code § 827, Rent increase notice: For QCTs in periodic tenancies (month-to-month), the statute requires 30-day advance written notice for increases up to 10%, and 90-day notice for increases greater than 10%. Increases are not effective until the notice period expires.
Civil Code § 1632, Lease translation: Commercial tenancy agreements with QCTs entered into on or after January 1, 2025 are subject to translation requirements for Spanish, Chinese, Tagalog, Vietnamese, and Korean-speaking tenants. If the lease negotiation was conducted primarily in one of those languages, the landlord must provide a translation before signing.
Civil Code § 1946.1, Termination notice: QCTs in periodic tenancies are entitled to 60 days' notice of lease termination (or 30 days if they have occupied the premises less than a year).
Section 1950.9 creates multiple enforcement mechanisms:
Affirmative defense: In any possession action based on nonpayment of the operating cost fee, the QCT's inability to verify the charges (due to the landlord's failure to provide documentation) is an affirmative defense. You don't have to pay a fee you can't verify.
Civil liability: If the landlord violates § 1950.9, the QCT may recover actual damages.
Attorneys' fees and costs: Courts have discretion to award attorneys' fees and costs to a prevailing QCT.
Treble and punitive damages: If the violation was willful, oppressive, fraudulent, or malicious, treble damages and punitive damages are available.
Injunctive relief: Members of the public also have a right to seek injunctive relief against violations.
For CAM overcharge claims not covered by § 1950.9 (for example, by tenants who don't qualify as QCTs, or for periods before January 1, 2025), California's breach-of-written-contract statute of limitations applies: four years under California Code of Civil Procedure § 337.
Generally, the limitations period runs from when the overcharge accrued, typically when the landlord issued the reconciliation statement containing the improper charge and the tenant had the information needed to recognize the dispute.
A 2,500 SF retail tenant in a Los Angeles strip center signed a five-year NNN lease in 2022. The lease caps total management compensation at 5% of the CAM pool. In 2024, the landlord began billing both a 5% property management fee and a separate 2% "administrative services" fee, pushing total management compensation to 7%.
CAM history:
| Year | Management Fee Billed | Lease Cap (5%) | Annual Overcharge |
|---|---|---|---|
| 2022 | $12,500 (5%) | $12,500 | $0 |
| 2023 | $13,100 (5%) | $13,100 | $0 |
| 2024 | $18,200 (7%) | $13,000 | $5,200 |
| 2025 | $18,800 (7%) | $13,400 | $5,400 |
| 2026 | $17,600 (7%) | $13,700 | $3,900 |
Recovery calculation (4-year California SOL):
| Category | Annual Overcharge | Years Recoverable | Total |
|---|---|---|---|
| Management fee stacking | $4,852 avg | 3 | $14,500 |
| Total estimated recovery | $14,500 |
CAMAudit flags this under Rule 3 (Management Fee Overcharge) by totaling all management-related fee lines and comparing the aggregate to the lease's stated cap.
SB 1103 became effective January 1, 2025. It does not apply retroactively to all existing leases. It applies to leases executed or commercial tenancies commenced or renewed on or after January 1, 2025, and to certain pre-2025 leases that do not already contain a building operating costs provision.
Who qualifies as a qualified commercial tenant (QCT):
To receive SB 1103's operating cost protections, a tenant must meet one of three size criteria and actively provide written notice to the landlord:
The size test alone is not enough. Tenants must also send the landlord a written self-attestation of QCT status within the prior 12 months, and renew that attestation annually. If you qualify under the size criteria but have not sent the attestation, you are not receiving the protections.
Notice period requirements:
Before executing a lease with a QCT, the landlord must provide written notice that the tenant has a right to inspect building operating cost records. This pre-execution notice is a landlord obligation, not something the tenant has to request.
After a QCT submits a written request for supporting documentation, the landlord has 30 days to respond. A landlord who misses the 30-day window is in violation of § 1950.9.
Disclosure requirements:
The statute requires landlords to disclose supporting documentation for operating cost charges upon a QCT's written request. The disclosure must be sufficient for the tenant to verify proportionate allocation and confirm that costs were incurred within the permissible window (previous 18 months or reasonably expected next 12 months). A summary line on a statement is not sufficient. The landlord must provide records that support each component of the fee.
Penalty provisions:
Section 1950.9 creates a graduated penalty structure:
The willfulness threshold for treble damages is significant. A landlord who has been put on notice of QCT status and then ignores a documentation request has a much harder time arguing the violation was inadvertent.
Before SB 1103 took effect, California commercial tenants had essentially no statutory rights specific to building operating cost documentation. Their protections came entirely from two sources: whatever audit rights clause (if any) appeared in their lease, and the general four-year statute of limitations for written contract claims under CCP § 337.
The gap that existed:
Prior to 2025, a small California restaurant tenant on a NNN lease with no audit rights clause had no mechanism to demand operating cost documentation at all. The landlord could bill what it wanted, and the tenant's only recourse was to sue for breach of contract, which required proving the specific overcharge without having seen the underlying records. That catch-22 was common enough that many small tenants simply paid whatever was billed rather than incur legal costs.
Large tenants with well-negotiated leases typically had audit rights clauses that allowed inspection of the landlord's books within a specified window after the annual reconciliation. But those rights required hiring a CPA, giving notice within the lease's audit deadline (often 90 to 180 days after receiving the reconciliation), and scheduling access to the landlord's records. The process was procedurally complex and practically inaccessible for small tenants.
What changed with SB 1103:
SB 1103 created a separate, simpler mechanism: a written request for supporting documentation that does not require scheduling a formal audit or hiring a CPA. The tenant just needs to be a QCT, have sent the annual attestation, and then submit a written request. The landlord responds within 30 days. No appointment, no CPA, no audit rights clause required.
The statute also created the affirmative defense against nonpayment, which changed the power dynamic. Before SB 1103, withholding CAM payment over a documentation dispute risked an eviction filing. After SB 1103, a QCT who cannot verify a charge has a statutory defense in any eviction action based on that charge.
What SB 1103 does not change:
The four-year statute of limitations under CCP § 337 still applies to all California commercial tenants for breach-of-written-contract claims, including CAM overcharges. Tenants who do not qualify as QCTs, or who are claiming overcharges from before January 1, 2025, still have this window to pursue claims. SB 1103 adds protections on top of the existing framework; it does not replace contract law.
Additionally, SB 1103 does not create a right to on-site inspection of the landlord's general ledger or primary records the way a traditional audit rights clause might. The statute requires supporting documentation but stops short of mandating full book access. Tenants with serious overcharge disputes may still need to proceed under lease audit rights clauses or CCP § 337 to get full discovery.

Determine if you qualify as a QCT. Review the microenterprise, restaurant, and nonprofit definitions under California law.
Send written attestation of QCT status to your landlord. A simple letter with your self-attestation is sufficient to trigger § 1950.9's protections.
If you receive a CAM or operating cost charge you cannot verify, send a written documentation request. Your landlord has 30 days to respond.
If the landlord fails to respond within 30 days, withhold payment with notice citing § 1950.9. Consult California commercial real estate counsel before taking this step.
Review your lease for the CAM provisions generally. Even with § 1950.9's protections, your lease terms govern allocation methods, exclusions, and audit rights for non-QCTs and for historical periods before 2025.
Does SB 1103 apply to leases signed before January 1, 2025?
Section 1950.9 applies to leases executed or tenancies commenced or renewed on or after January 1, 2025, and to certain older leases that do not contain a building operating costs provision. For leases signed before 2025 that contain CAM provisions, the statute's scope is more limited. Consult qualified California commercial real estate counsel for analysis of a specific lease situation.
What is a microenterprise under California law?
California's microenterprise definition typically refers to businesses with 5 or fewer employees, including the owner. Confirm the specific statutory definition against current California Small Business Development Act provisions, as the definition may be cross-referenced.
If I qualify as a QCT, do my lease audit rights still matter?
Yes. The statutory right under § 1950.9 and your contractual audit rights (if any) coexist. A lease audit rights clause (if present) may provide broader access to records than the documentation request mechanism. For tenants with strong lease audit rights and QCT status, both mechanisms are available.
Does the translation requirement under § 1632 apply to lease amendments and renewals?
SB 1103 applies the § 1632 translation requirement to tenancy agreements entered into on or after January 1, 2025. Whether it applies to amendments and renewals may depend on how the amendment is structured. Qualified California counsel should advise before signing.
What if my landlord claims my business does not qualify as a QCT?
If the landlord disputes your QCT status, that dispute would need to be resolved under California law. Maintaining records of your attestation letters is advisable, as the statute places the attestation burden on the tenant and requires annual renewal of the notice.
How far back can California tenants recover CAM overcharges?
Under CCP § 337, California tenants have four years from when each overcharge accrued. For an audit initiated in 2026, claims for reconciliations going back to approximately 2022 are generally within the window. Earlier years may be time-barred depending on accrual dates.
