Commercial leasing in Massachusetts, which is founded on common law and the Massachusetts Constitution (1780), is governed primarily by contract law, not the heavily protective tenant statutes that apply to residential tenancies. The strict security deposit rules of MGL Ch. 186, §15B, the 30-day late fee grace period, and the implied warranty of habitability do not apply to commercial leases.
Official Law Citation: Commercial tenancies are governed by contract law, common law, and the eviction process detailed in M.G.L. Chapter 239.
Contract Law Governs
Unlike residential tenancies, commercial leases in Massachusetts are essentially business-to-business contracts. Parties have broad freedom to negotiate terms regarding rent, security, repairs, and termination. However, under M.G.L. c. 186, § 15, any provision in a commercial lease that seeks to indemnify or hold a landlord harmless for their own negligence, omission, or misconduct is deemed against public policy and void. The courts generally hold both parties to the agreed-upon terms, with fewer "escape hatches" for tenants.
Common Commercial Lease Structures
Triple Net (NNN) Leases
NNN leases are very common in Massachusetts, particularly for retail and industrial properties. The tenant pays:
- Base rent.
- Their proportionate share of property taxes.
- Their share of building insurance.
- Common Area Maintenance (CAM) charges.
Gross Leases
More common for smaller office spaces, where the tenant pays a flat rent and the landlord covers operating expenses.
Landlord Remedies and Mitigation
In Massachusetts, a commercial landlord has a duty to make reasonable efforts to mitigate damages unless the lease contains an enforceable liquidated damages or rent acceleration clause (NPS, LLC v. Minihane, 451 Mass. 417). If the lease contains such an enforceable clause, the landlord may collect the remaining rent without an obligation to re-rent the space. If the lease is silent on default remedies, traditional contract principles require reasonable mitigation efforts.
(Note: The case Wesson v. Leone Enterprises, Inc. established that commercial lease covenants are mutually dependent, meaning a tenant may legally break the lease if the landlord fails to maintain essential services.)
Eviction: Summary Process in District or Superior Court
Commercial evictions follow a "Summary Process" framework (M.G.L. Chapter 239), but with key differences from residential proceedings:
- Termination for Non-Payment (M.G.L. c. 186, § 11A): Upon the neglect or refusal by the tenant to pay rent due under a written commercial lease, the landlord may terminate the lease in accordance with specific lease provisions or, in the absence of such provisions, by a 14-day written notice to quit. If terminated via the 14-day notice, the tenant has a statutory right to cure by paying all rent due, interest, and costs before the answer date in a summary process action.
- Jurisdiction: Commercial summary process actions must be brought in the District Court or Superior Court. Under M.G.L. c. 239, § 2, the Housing Court generally lacks jurisdiction over purely commercial tenancies.
- Waivers: Commercial tenants often waive their right to a jury trial in the lease, speeding up proceedings.
- Defenses: Tenant defenses (like habitability) are far more limited.

Frequently Asked Questions
▶What are the Massachusetts landlord-tenant laws every property owner should know?
Massachusetts has a reputation as one of the most tenant-protective states in the United States. Governed primarily by Massachusetts General Laws (MGL) Chapter 186 alongside the State Sanitary Code, the Commonwealth imposes strict regulations on security deposits, eviction procedures, habitability, and-as of 2025-real estate broker fees. This guide covers the essential compliance requirements for property owners and landlords.
Read the complete guide▶What is the Massachusetts eviction process and how long does it take?
The Massachusetts eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Massachusetts. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Massachusetts security deposit rules and return deadlines?
Massachusetts has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Massachusetts rent increase laws and caps for landlords?
Massachusetts has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Massachusetts has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Massachusetts?
Massachusetts has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable. Check Massachusetts state law and any applicable local ordinances for the exact grace period and late fee limits that apply to your rental property.
Read the complete guide▶What disclosures must Massachusetts landlords provide to tenants?
Massachusetts landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
Read the complete guide▶What are the Massachusetts lease requirements for rental properties?
Massachusetts recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Massachusetts law.
Read the complete guide▶What are Massachusetts landlord maintenance obligations and habitability standards?
Massachusetts landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control. Tenants typically have the right to request repairs in writing, and if repairs are not made within a reasonable time, tenants may have legal remedies available.
