Massachusetts Commercial Lease Laws

By Angel Campa, Founder · Updated March 2026

Massachusetts commercial landlord-tenant law is primarily driven by common law and the specific terms of the negotiated lease, operating in a legal environment that otherwise imposes some of the strongest residential tenant protections in the nation. The Massachusetts General Laws (M.G.L.) do not contain a comprehensive commercial landlord-tenant act, leaving commercial disputes largely to contract interpretation, equity, and the general property statutes under M.G.L. Chapter 186. The state's courts have developed a well-established body of commercial real estate case law that practitioners must navigate alongside the statutory framework.

Self-help evictions are categorically prohibited under Massachusetts common law for commercial premises. Landlords must use the Summary Process (eviction) procedure under M.G.L. Chapter 239, requiring proper written notice and a formal court filing. Massachusetts is notable for its Consumer Protection Act (M.G.L. Chapter 93A), which can be asserted in commercial landlord-tenant disputes involving unfair or deceptive practices, adding meaningful litigation risk — including multiple damages and attorney's fees — for landlords who act in bad faith.

CAM & Operating Expense Audit Rights

No statutory audit rights; governed entirely by negotiated lease terms.

Massachusetts does not grant commercial tenants any statutory right to audit landlord operating expenses or CAM charges. All audit provisions — including the right to audit, the look-back period, the identity of the auditor, cost allocation, and confidentiality obligations — must be negotiated and clearly stated in the lease. The state's Chapter 93A consumer protection statute can, however, create meaningful legal exposure for a landlord who intentionally provides materially false expense reconciliations, providing an alternative litigation pathway for tenants who lack a contractual audit clause.

Frequently Asked Questions

Can a Massachusetts landlord use self-help to evict a commercial tenant?
No. Massachusetts strictly prohibits self-help evictions for commercial premises. A landlord who changes locks, removes doors, or shuts off utilities to force out a commercial tenant faces significant tort liability and potential Chapter 93A multiple damages claims.
What notice is required for a commercial eviction in Massachusetts?
For nonpayment of rent in a tenancy at will, a 14-day notice to quit is required under M.G.L. Chapter 186 Section 11. The landlord must then file a Summary Process action in the appropriate court after the notice period expires.
Does Chapter 93A apply to commercial lease disputes in Massachusetts?
Yes. When a landlord engages in unfair or deceptive conduct in a commercial leasing context, a tenant may assert a Chapter 93A claim in addition to breach of contract, potentially recovering up to three times actual damages plus attorney's fees.
Are commercial security deposits regulated in Massachusetts?
No. Massachusetts' strict residential security deposit statute (M.G.L. Chapter 186 Section 15B) does not apply to commercial leases. Commercial deposit amounts and return procedures are governed solely by the lease agreement.
