Since Massachusetts achieved statehood on February 6, 1788, its commercial real estate framework has relied heavily on the "caveat emptor" (buyer beware) principle, though modern statutes have introduced several mandatory disclosures. While commercial landlords are not subject to the extensive consumer-protection disclosures required in residential leasing (like the §15B Statement of Condition), they face significant regulatory obligations regarding environmental contamination, building safety, and insurance information.
Official Law Citation: Massachusetts General Laws Chapter 21E (Massachusetts Oil and Hazardous Material Release Prevention and Response Act); MGL c. 93A (Regulation of Business Practices for Consumers Protection).
1. Environmental Disclosures (MGL Ch. 21E)
Massachusetts has strict environmental liability laws. Under MGL Chapter 21E (the Massachusetts Contingency Plan, or MCP), the current property owner can be held liable for hazardous waste contamination, regardless of who caused it.
- Phase I Environmental Site Assessment (ESA): While not legally required for every lease, it is standard practice for a commercial tenant to commission (or request from the landlord) a Phase I ESA before signing a lease. This report identifies potential environmental contamination risks.
- Activity and Use Limitations (AULs): If a property has a recorded AUL (a restriction on land use due to prior contamination), the landlord must disclose this. AULs are public record and recorded at the Registry of Deeds.
- Asbestos & Lead Paint: For commercial buildings, landlords must disclose known asbestos-containing materials (ACMs) under DEP and OSHA regulations. Failure to disclose known material defects can also trigger liability under MGL c. 93A.
2. Fire Insurance Disclosure (MGL c. 186, § 21)
A specific statutory requirement often overlooked in commercial leasing is the fire insurance disclosure.
- The Rule: Upon written request by a tenant, a landlord must disclose in writing within 15 days the name of the company insuring the property against fire loss, the amount of insurance, and the name of the person who would receive the loss payment.
- Applicability: This applies to both residential and commercial properties in Massachusetts.
3. ADA Compliance
The Americans with Disabilities Act (ADA) requires that commercial properties (places of "public accommodation") be accessible to people with disabilities.
- Landlord's Obligation: The landlord is generally responsible for ensuring the building's common areas (parking lots, entrances, lobbies, restrooms) are ADA-compliant.
- Disclosure: Landlords should disclose any known ADA non-compliance issues before the lease is signed, as failure to do so may shift liability and constitute an unfair business practice under MGL c. 93A.
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.

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.

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.

Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.

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.
