Commercial tenants disputing CAM overcharges face different retaliation rules than residential. Learn what the law says and how to protect yourself.
TL;DR: Commercial tenants have almost no statutory anti-retaliation protection in most states. California, Texas, New York, and Florida anti-retaliation statutes cover residential tenants only. Your best protection is a professional, well-documented dispute and anti-retaliation lease language. Verbal threats connected to your dispute should be documented and reviewed by an attorney immediately.

An adverse action by a landlord, such as non-renewal, rent increase, or threatened eviction, that is causally connected to a tenant's exercise of their legal or contractual rights. Commercial tenants have limited statutory protection against retaliation in most U.S. states; protection depends primarily on lease language and common-law claims.
“I built CAMAudit because tenants deserve to know what they are owed. The fear of retaliation is real, but institutional landlords respond to documented disputes differently than tenants expect. A letter backed by specific calculations signals a tenant who will escalate. Most landlords find it cheaper to settle than to replace a good tenant over a CAM dispute.”
The fear of retaliation stops more tenants from disputing CAM overcharges than any other single factor. It is worth understanding what that risk actually looks like, because the legal picture for commercial tenants is different from residential, and the practical picture is often less dire than tenants imagine.
The straightforward version: commercial tenants in most U.S. states have almost no statutory protection against landlord retaliation, and the protection that does exist was designed for residential occupancies.
California's anti-retaliation statute (Civil Code § 1942.5) covers only tenants of a "dwelling." It explicitly excludes commercial tenants. Texas's landlord-retaliation provisions (Property Code Chapter 92) similarly apply only to residential leases. New York's RPL § 223-b protects tenants of dwelling units, not commercial occupants. Florida Statute § 83.64 forbids retaliatory eviction under Chapter 83, which covers residential landlord-tenant relationships, not commercial ones.
Illinois is a partial exception. Its Landlord Retaliation Act (765 ILCS 721/5, effective January 1, 2025) prohibits a landlord from "knowingly terminat[ing] a tenancy, increas[ing] rent, or refus[ing] to renew" because a tenant reported a violation or exercised a legal right. The language is broad, "tenant" is not expressly limited to residential occupancies, but the statutory context and legislative history suggest it targets residential habitability situations.
The industry commentary is direct: anti-retaliation laws are "statutory in most states" for residential leases but "not typically available" for commercial leases.
California: No anti-retaliation statute for commercial tenants. Civil Code § 1942.5 explicitly covers only "dwellings." A commercial tenant who claims retaliation must rely entirely on contract (lease language) or common-law theories.
Texas: Property Code Chapter 92 (retaliation provisions) applies only to residential tenancies. Commercial tenants have no equivalent statutory protection. Texas courts have consistently enforced eviction rights against commercial tenants without any retaliation defense.
New York: RPL § 223-b protects "dwelling units" from retaliatory eviction. Commercial tenants have no statutory equivalent. New York courts have confirmed that commercial tenants cannot assert retaliatory eviction as a defense absent an express lease provision.
Florida: Chapter 83's anti-retaliation provision (§ 83.64) sits within the residential landlord-tenant law. Commercial tenants have no statutory protection under this chapter.
Illinois: 765 ILCS 721/5 (the new Landlord Retaliation Act) is the most favorable statute for commercial tenants among the major commercial real estate states, but its applicability to commercial leases remains untested in appellate case law as of early 2026.
The absence of a clear statute does not mean commercial tenants have no remedy if they can prove retaliation. Courts have addressed this in at least one commercial context worth knowing.
In Subway Real Estate v. AG-LC 1315 Third Owner, L.P. (Cal. App. 2020), Subway, a commercial tenant, alleged that the landlord threatened eviction and imposed improper CAM and rent charges after Subway disputed those charges. The landlord filed an anti-SLAPP motion to strike Subway's retaliatory eviction claim, arguing it was barred because Subway was a commercial tenant without a statutory right to assert retaliation. The appellate court denied the anti-SLAPP motion and affirmed that the retaliatory eviction claim could proceed to trial.
This is notable. It means at least one California court declined to dismiss a commercial tenant's retaliation claim at the pleadings stage, even without a supporting statute. The parties ultimately settled, so there was no final merits ruling on whether retaliation was proven, but the claim survived long enough to create settlement leverage.
The general rule, confirmed across jurisdictions: commercial tenants cannot use retaliatory eviction as an affirmative defense in a possession proceeding unless they have surrendered possession (i.e., moved out and are suing for wrongful eviction). As one California commentary states, a commercial tenant who stays in possession cannot assert a common-law retaliatory eviction defense.
The legal picture is grim for commercial tenants, but the practical picture is more nuanced.
Most commercial landlords are institutional investors or property management companies whose primary interest is generating stable rental income. A landlord who retaliates against a tenant with a legitimate CAM dispute faces several practical constraints:
Vacant space costs money. Replacing a tenant costs landlords three to six months of rent in commissions, tenant improvements, and carrying costs. Retaliating against a tenant who has otherwise been a good occupant for the sake of a CAM dispute is economically irrational for most landlords.
Written documentation creates exposure. A landlord who sends written communications suggesting that an eviction or rent increase is connected to a CAM dispute has created documentary evidence that could support a retaliation claim in litigation, even without a supporting statute, as Subway Real Estate shows.
Sophisticated tenants have negotiating leverage at renewal. A landlord who knows the tenant has documented a $40,000 overcharge and is prepared to dispute it will often find it cheaper to settle the dispute and renew on fair terms than to escalate.
The tenants most vulnerable to retaliation are those in weak markets with limited alternatives, those approaching lease expiration without negotiating leverage, and those with leases that give the landlord broad discretion to raise CAM estimates or classify maintenance costs. For these tenants, the risk is real and the mitigation strategies below matter most.
Document everything. Before sending any dispute letter draft, create a clear record of your evidence: the reconciliation statement, your calculations, the lease provisions at issue, and your payment history. If retaliation occurs later, you need to show that your dispute was well-founded and preceded any landlord action.
Keep dispute correspondence professional. Letters that are specific, calm, and grounded in lease language are harder to characterize as hostile or threatening. A well-constructed dispute letter draft is a business communication; an angry letter threatening social media campaigns or regulatory reporting is easier to dismiss and may actually trigger the defensive response you are trying to avoid.
Negotiate anti-retaliation language into future leases. Tenants negotiating renewals or new leases can request a provision that expressly prohibits the landlord from taking adverse action (rent increases, non-renewal, service reduction) in response to a formal dispute. Many institutional landlords will accept this language because it is essentially a promise to behave reasonably, something they would say they are already doing.
Know your lease renewal terms. If your lease renewal is coming up within 12 months, understand what control the landlord has over renewal terms. In a month-to-month or automatically renewing lease with market-rate adjustments, the landlord has more flexibility to restructure terms. In a fixed-rate lease with defined renewal options, they have much less.
If you believe a landlord action (rent increase, non-renewal, reduced services, threatened eviction) is connected to your CAM dispute, do three things immediately:
Document the timeline. Write down every event with dates: when you sent the dispute letter draft, when the landlord received it, when the landlord action occurred, any communications connecting the two. The closer the temporal connection, the stronger any potential claim.
Look at your lease. Some leases include non-retaliation covenants or require the landlord to provide advance notice before any rent increase. Even without a statute, a lease breach claim is available if the landlord violated a specific contractual term.
Consult an attorney. If the retaliation is serious, threatened eviction, dramatic rent increase tied explicitly to the dispute, you need legal advice quickly. The Subway Real Estate case shows this territory is not hopeless, but navigating it without legal counsel is risky.
