In Massachusetts restrictions created after 1961 expire after 30 years.

You may need to obtain a release from the owner who created the covenant. You can add more details regarding the nature of the covenant on the discussion page.

Deed restrictions are recited in the deed by which the restriction was created but they are not always carried forward on subsequent deeds. Even if not recited, the land is subject to the restriction as long as the original restriction was recorded in the land records. The purpose of a comprehensive title examination is, in part, to disclose all the encumbrances, restrictions, liens, claims, etc., that affect the land.
