State-specific guide for CAM audit partners in California, covering SB 1103 qualified commercial tenant protections, California NNN audit rights, and overcharge patterns in LA, Bay Area, and San Diego markets.
In 2025 California gave small commercial tenants a new right. Most of those tenants still do not know it exists. The law is SB 1103, in force January 1, 2025. It is the first state CAM rights law for "qualified commercial real estate clients." I built CAMAudit before SB 1103 passed. But the law has opened a real door for partners in California. You may be a CPA, an attorney, or a fractional CFO. SB 1103 gives you a reason to bring up CAM audit with clients. You did not have that reason before.
This guide covers the SB 1103 rules. It covers leases in Los Angeles, the Bay Area, and San Diego. And it covers the white-label numbers for California firms.
Qualified commercial tenant (California SB 1103): Under California SB 1103 (in force January 1, 2025), a qualified commercial tenant is a business with 5 or fewer employees in retail, restaurant, or service space, or a nonprofit. These tenants get an itemized CAM statement, backup documents within 21 days of a request, and a 60-day window to dispute the reconciliation. The reconciliation is the landlord's year-end CAM bill. Other tenants, like bigger firms and office tenants, keep only the audit rights in their lease.
California has no broad commercial landlord law. It has one for homes, but not for commercial space. For years, commercial leases ran on contract law alone. Each tenant had to win audit rights at the table.
SB 1103 picked out small commercial tenants. It gave them rights by law. It covers California commercial space. The lease must be signed, renewed, or extended on or after January 1, 2025. The main rights:
The right to an itemized CAM statement. Qualified tenants get a written reconciliation. It must list each cost type and the total. It must show the tenant's pro-rata share. Pro-rata share is the tenant's slice of building costs. It must show the tenant's dollar share and any credits from estimated payments.
The right to backup documents. When the tenant asks, the landlord must send proof of the CAM charges within 21 days. This is a real change. Small tenants had no legal way to force this before.
A 60-day window to dispute. Qualified tenants have 60 days from the reconciliation to dispute in writing. This deadline is set by law, not by the lease. So a landlord cannot cut it short for covered tenants.
What SB 1103 leaves out. It only covers qualified tenants. Firms with more than 5 staff are out. Office, industrial, and large retail tenants are out too. For them, audit rights still come from the lease alone. The deadline to sue on a written contract is four years. That comes from California Code of Civil Procedure Section 337.

Los Angeles is one of the biggest commercial markets in the country. Large REITs own much of its retail and mixed-use space. A REIT is a big real estate owner. That makes billing very systemized. So overcharges show up in the same few buckets.
Big owners hold many LA strip centers. You see this in the San Fernando Valley, the South Bay, and the east San Gabriel Valley. The most common overcharges:
Management fee overcharges. Big LA landlords often charge a 4 to 6 percent management fee. They base it on the rent they collect. They also tack on extra admin line items. Many leases signed before 2020 cap that fee at 3 to 4 percent. When the bill tops the cap, the extra is an overcharge. See CAMAudit's Rule 3.
Gross-up errors. Gross-up adjusts shared costs as if the building were full. LA retail with empty space is prone to gross-up errors. This got worse after COVID. When a landlord grosses up past what the lease allows, every tenant pays a bigger CAM share.
Controllable expense cap breaks. Some costs are capped by the lease. These are controllable expenses. California costs jumped after 2021. Labor, utilities, and insurance all rose. Many leases cap these at 3 to 5 percent a year. Many LA buildings now break that cap.
LA built a wave of mixed-use space in Culver City, Hollywood, and the Arts District. These leases have tricky CAM setups. They blend retail, restaurant, office, and home cost pools. The split between pools is hard to check by hand. CAMAudit's pro-rata share rule catches these split errors in mixed-use buildings.
| Overcharge Type | LA Frequency | Primary Property Type |
|---|---|---|
| Management fee overcharge | High | Strip center, power center |
| Gross-up violation | Medium-high | Mixed-use, class A retail |
| Controllable expense cap violation | High | All commercial types |
| Insurance overcharge | High | Post-2021 California market |
| Pro-rata share denominator error | Medium | Power center, mixed-use |
San Francisco has lots of empty offices since remote work grew. Even so, the Bay Area is one of the toughest CAM markets in the US. Class A offices have big owners, many tech tenants, and complex leases. Class A means top-tier office space. All of that breeds several kinds of overcharge.
Gross-up errors. Almost every Bay Area Class A office lease has a gross-up rule. It adjusts costs as if the building were 95 percent full. When vacancy spiked after 2020, landlords grossed up off bigger bases. A correct gross-up only adjusts costs that move with use. It leaves out fixed costs like property tax and base fees. When landlords gross up fixed costs, the tenant pays too much.
Base year errors. Base year is the cost level a lease compares later years against. Tenants who signed in 2020 or 2021 face high risk here. Those buildings ran at 40 to 60 percent full in the base year. So base-year costs were low. Later years run higher even at normal use. The tenant then owes far more than it bargained for.
Broken exclusion lists. Bay Area tech tenants fight for long exclusion lists. These keep landlord overhead, high fees, and capital work out of the CAM pool. Capital work is a big one-time upgrade. Landlords break these lists with one-size billing systems. Those systems ignore the exact lease terms.
Transit-side offices (Caltrain and BART). These buildings have odd cost setups. They sometimes pass transit upkeep through as building costs. CAMAudit's Rule 2 (Excluded Service Charges) fits these buildings well.
San Diego has three market types. Each has its own overcharge pattern.
Medical office buildings. San Diego has a lot of medical space. You see it in Kearny Mesa, Mission Valley, and the La Jolla corridor. These leases have special cost setups. They cover custom HVAC, lab systems, and rule-driven upkeep. When the landlord bills these as normal costs with no lease backing, they are excluded service charges.
Biotech campuses. The Torrey Pines and Sorrento Valley biotech areas run on NNN leases. These leases have detailed gross-up and capped-cost rules. Biotech tenants ask for lab-grade building systems. Those special costs often slip into the shared CAM pool for all tenants.
Border retail (South San Diego, Chula Vista, Otay Ranch). Retail near the US-Mexico border draws heavy foot traffic. That drives up common area upkeep. Watch the management fees and capped costs in these spots closely.
"California is the only state where a law now sets a deadline for small commercial landlords. Under SB 1103, a qualified tenant with no itemized statement can demand one by law. I built CAMAudit to catch the billing errors in that statement once it arrives." - Angel Campa, Founder, CAMAudit
California firms pay more to run than firms in most states. But your clients sign bigger leases. That means bigger CAM bills to check.

What is California SB 1103 and how does it affect commercial CAM disputes?
SB 1103, effective January 1, 2025, created new protections for "qualified commercial real estate clients" in California. Qualified tenants (businesses with 5 or fewer employees occupying retail, restaurant, or service space, and nonprofits) get a 60-day CAM reconciliation dispute window, the right to itemized CAM statements, and the right to request supporting documentation within 21 days. Larger commercial real estate clients who don't meet the qualified tenant definition rely entirely on their lease audit clause.
Who qualifies as a "qualified commercial tenant" under California SB 1103?
A qualified commercial tenant under SB 1103 is a business with 5 or fewer employees that occupies retail, restaurant, or service space, or a nonprofit organization. The statute applies to tenants in these categories regardless of the size of their space. Larger businesses, tech tenants, and office occupiers who don't meet the definition are not covered and must rely on contractual audit rights in their lease.
What CAM overcharges are most common in the Los Angeles commercial market?
Los Angeles strip center and mixed-use retail tenants most commonly encounter management fee overcharges from institutional REIT ownership structures, gross-up violations in buildings with variable occupancy, and controllable expense cap violations from California's elevated operating costs. The LA market's high management fee rates, often 4 to 6 percent, create systematic overcharge exposure when leases cap fees at lower percentages.
What makes Bay Area office CAM disputes different from standard NNN retail disputes?
Bay Area Class A office leases commonly include complex gross-up provisions that allow landlords to normalize expenses to 95 percent occupancy. When a landlord applies the gross-up incorrectly, inflating the grossed-up base year or applying it to excluded expense categories, the error compounds across every year of the lease. Bay Area tech tenants also negotiate expense exclusion lists that don't always match the landlord's standardized billing system, creating recurring overcharges in the same categories year after year.
How can California CPAs and fractional CFOs use SB 1103 as a service trigger?
SB 1103 created a new statutory deadline that California advisors can use to trigger CAM review conversations. Any qualified commercial tenant client who hasn't received an itemized CAM statement or hasn't been informed of their 60-day dispute window is potentially leaving money on the table under rights they have by law since January 1, 2025. Advisors who flag this exposure build credibility and create a natural entry point for a CAMAudit white-label engagement.
What is the statute of limitations for CAM overcharge claims in California?
California applies a 4-year statute of limitations for written contract claims under California Code of Civil Procedure Section 337. The clock typically starts when the landlord delivers the annual reconciliation containing the overcharge. A tenant auditing in 2026 can generally recover overcharges from reconciliations delivered as far back as 2022 under the general contract SOL, though SB 1103's 60-day dispute window creates a shorter operational deadline for qualified commercial real estate clients.
