Massachusetts Rental Air Quality and Ventilation Standards

Massachusetts renters have the right to a safe living environment, including proper air quality and ventilation inside their homes. State law sets minimum health and safety requirements to protect renters from hazards such as mold, poor ventilation, dampness, and indoor air pollutants. Understanding these standards can help you spot problems early and ensure your landlord follows the law.

Air Quality Rules for Massachusetts Rentals

The Massachusetts State Sanitary Code outlines the official rules for maintaining safe indoor air in rental properties. Landlords are required to provide safe levels of ventilation and take reasonable steps to address issues that could impact air quality.

• Ventilation: All habitable rooms must have at least one window that can be opened, or another mechanical system (like a fan) to provide fresh air and remove moisture.
• Moisture and Mold: Landlords must fix leaks and moisture problems to prevent mold, which can be a serious health hazard.
• Heating: Proper heating is required to prevent damp conditions that could affect air quality.
• Combustion Appliances: Gas stoves, furnaces, and other fuel-burning appliances must be vented and maintained for safe operation.

If your rental unit has poor ventilation, persistent moisture, mold, or strong odors, these may violate minimum safety standards under the Massachusetts regulations.^[1]

What to Do If You Have Air Quality or Ventilation Problems

If you notice issues with indoor air quality or ventilation, you have several options to resolve the situation:

• Notify your landlord in writing and request repairs or remediation.
• Keep copies of all your communications and take photos of affected areas for documentation.
• If the landlord does not fix the problem in a reasonable time, contact your local Board of Health for an official inspection. They can issue an order requiring the landlord to make repairs.

Relevant Official Forms

• Board of Health Complaint Form
  When to use: If your landlord does not address air quality or ventilation issues after being notified, you can file this form with your local Board of Health to request an inspection.
  Find your local Board of Health and access complaint forms.
• Tenant Request for Inspection (No formal number)
  How to use: Massachusetts does not have a statewide inspection form, but most local Boards of Health provide online or printable forms. A tenant completes this to initiate a housing code inspection for air quality or ventilation problems.
  Example: You notice persistent dampness and musty odors in your apartment bathroom and your landlord does not respond, so you file the request form with your city health department.

In most cases, the Board of Health will send an inspector within a few days to check your rental unit. If violations are found, the landlord will receive an official order to fix issues within a specified time.

Tribunal Handling Tenancy Matters

In Massachusetts, the Massachusetts Housing Court oversees disputes between landlords and tenants, including issues related to habitability, repairs, and air quality.
