Selling a House With Unpermitted Work in Massachusetts (2026)

Finished basements, room additions, and electrical upgrades done without permits are common in Massachusetts' older housing stock. Here's how it affects your sale — and how to close without permits.

Disclose — Then Sell As-Is

Massachusetts MGL Chapter 93A requires disclosure of known material defects and material facts that affect the value or desirability of a property. Unpermitted work is a material fact — disclose it on the Seller's Statement of Property Condition. After disclosure, you can sell as-is to a cash buyer who accepts the disclosed condition without requiring any permit resolution.

FHA/VA Appraisal Impact vs. Cash Buyer — By Work Type

Frequently Asked Questions

Do you have to disclose unpermitted work when selling a house in Massachusetts?

Yes — MGL Ch. 93A requires disclosure of known material facts. Unpermitted additions, finished basements, electrical, and plumbing done without a permit are material facts. Disclose on the Seller's Statement, then sell as-is. Concealment risks treble damages plus attorney fees.

How does unpermitted square footage affect a Massachusetts home sale?

FHA and VA appraisers must exclude unpermitted square footage from GLA unless local records include it. A 2,200 sq ft home with 400 sq ft of unpermitted basement finish may be appraised as 1,800 sq ft — reducing value and potentially killing the deal. A cash buyer does not use an appraisal, so unpermitted square footage doesn't affect the process.
