Radon When Buying or Selling a Home in Massachusetts

Massachusetts doesn’t require a radon test when a home is sold. Buyers receive state information about home inspections, which covers radon, and they can choose to include a radon test and a radon contingency in their offer.

For buyers

• Ask for a radon test as part of your home inspection, ideally by a professional with a continuous monitor.
• If you want protection, put a radon contingency in the purchase agreement. The seller has to agree to it.
• A high result doesn’t have to kill a deal: a mitigation system is a known, fixable cost you can negotiate.

For sellers

• Testing before you list avoids surprises during the buyer’s inspection.
• If a level comes back high, installing a system and retesting can make the house easier to sell.
• If a past deal fell through over radon, real estate agents may have a duty to disclose that to future buyers.

This is general information, not legal advice. For your specific deal, ask your real estate attorney.
