Massachusetts Commercial Property Disclosures: Environmental, ADA, and Zoning

While Massachusetts 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 accessibility.

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 (especially older ones common in Boston, Cambridge, and Worcester), landlords should disclose known asbestos-containing materials (ACMs). Lead paint disclosures, while primarily residential, can also apply to mixed-use buildings.

2. 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.
• Tenant's Obligation: The tenant is responsible for ADA compliance within their leased space.
• Disclosure: Landlords should disclose any known ADA non-compliance issues before the lease is signed, as failure to do so may shift liability.

3. Zoning and Use Disclosures

Massachusetts municipalities have detailed zoning regulations. A commercial landlord should ensure the tenant's intended use aligns with the property's zoning designation.

• Certificate of Occupancy (CO): The tenant may need a CO for their specific use. The lease should dictate who is responsible for obtaining it.
• If the property requires a zoning variance or special permit for the tenant's use, the lease should clearly state which party bears the cost and risk of the application.

4. Building Code and Safety

• Fire Safety: Commercial properties must have sprinkler systems and fire alarm systems that comply with the Massachusetts State Building Code (780 CMR). Any known deficiencies should be disclosed.
• Elevator Certificates: If the building has an elevator, the inspection certificate must be current and displayed.
