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.
