Massachusetts Commercial Maintenance: NNN Leases and CAM Charges

In Massachusetts commercial leasing, the division of maintenance responsibility is primarily driven by the lease, but it is subject to significant statutory and common law exceptions. While the implied warranty of habitability that protects residential tenants does not apply to commercial leases (Humphrey v. Byron), landlords retain non-waivable duties regarding safety and negligence.

Official Law Citation: Commercial maintenance is governed by a combination of lease terms, common law precedents, and specific statutes. Under M.G.L. c. 186, § 19, landlords have a non-waivable duty to correct unsafe conditions. Furthermore, M.G.L. c. 186, § 15 prevents landlords from contracting out of liability for their own negligence in property maintenance.

NNN Lease: Tenant Responsibilities and Statutory Exceptions

In a standard Triple Net (NNN) lease, the commercial tenant typically assumes responsibility for maintenance and repair costs, including:

• Interior maintenance (painting, flooring, plumbing fixtures).
• HVAC system maintenance and repair.
• Exterior maintenance (depending on lease terms).
• Structural repairs (if specified in the lease).

Important Exception: Notwithstanding any lease provision to the contrary, under M.G.L. c. 186, § 19, a landlord has a non-waivable statutory duty to exercise reasonable care to correct an "unsafe condition" on the premises. This duty is triggered within a reasonable time after the landlord receives written notice from the tenant via registered or certified mail. This applies even in "true" NNN leases where the tenant is otherwise responsible for all repairs (Bishop v. TES Realty Trust).

Doctrine of Mutually Dependent Covenants

Massachusetts has abandoned the traditional common law rule of "independent covenants" for commercial leases. Under the doctrine established in Wesson v. Leone Enterprises, Inc. (2002), if a landlord fails to perform a significant maintenance promise (such as failing to repair a leaking roof) that served as a "significant inducement" for the tenant to enter the lease, the tenant may have the legal right to terminate the lease and recover relocation costs.

Anti-Indemnification and Liability

Under M.G.L. c. 186, § 15, any provision in a commercial lease that attempts to exculpate a landlord from liability for injuries caused by the landlord's own negligence in the maintenance or repair of the premises or common areas is void and unenforceable. Landlords cannot use the lease to shield themselves from the consequences of failing to maintain safe conditions.

Gross Lease: Landlord Maintains

In a Gross lease structure, the landlord embeds the maintenance costs into the rent:

• The landlord maintains the building's structure, exterior, roof, and major systems (HVAC, elevator, plumbing).
• The tenant maintains the interior of their premises (lighting, minor repairs, cleanliness).

CAM (Common Area Maintenance) Charges

For multi-tenant commercial properties in Massachusetts, the landlord maintains the common areas and charges tenants a proportionate CAM fee.

There is no specific Massachusetts statute governing CAM charges or audit rights; these are strictly contractual. If the lease is silent on audit rights, the tenant generally has no statutory right to demand an audit of the landlord's books.

CAM charges typically cover:

• Landscaping and snow removal (critical in Massachusetts winters).
• Parking lot maintenance and lighting.
• Lobby and hallway cleaning.
• Elevator maintenance.
• Security systems.

Negotiating CAM Caps

Because CAM rights are strictly contractual in Massachusetts, tenants should negotiate:

• Annual caps on CAM increases (e.g., 3-5% maximum annual increase).
• Audit rights to verify the landlord's actual expenditures.
• Exclusions for capital expenditures, management fees above a certain percentage, and costs attributable to other tenants' negligence.

End-of-Lease Restoration

Many commercial leases require the tenant to "restore" the premises to their original condition at the end of the lease, including:

• Removing all non-structural tenant improvements (partition walls, custom flooring).
• Repairing any damage caused during the removal.
• Leaving the premises in "broom clean" condition.

If the tenant fails to restore, the landlord will perform the work and charge the cost to the tenant or deduct it from the security deposit.
