Commercial leasing in Massachusetts 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.

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. 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.
The Duty to Mitigate Damages
A critical Massachusetts-specific rule: under Fifty Associates v. Prudential Insurance Co. (1994), commercial landlords have a duty to mitigate damages if a tenant breaks the lease and vacates early. The landlord must make reasonable efforts to re-let the space. This is more tenant-friendly than many other states.
Eviction: Summary Process in District/Superior Court
Commercial evictions follow a similar "Summary Process" framework to residential evictions, but with key differences:
- Filed in District Court or Superior Court (not Housing Court).
- Commercial tenants often waive their right to a jury trial in the lease, speeding up proceedings.
- Tenant defenses (like habitability) are far more limited.
