On February 26, the Executive Office of Housing and Economic Development published preliminary guidance for local officials on determining voting thresholds for zoning ordinances and bylaws under the new Housing Choice law.
The guidance, along with other information on the changes made to M.G.L. ch. 40A, can be found online on the Mass.gov webpage for Housing Choice and MBTA Communities Legislation.
The page also includes a link to request an advisory opinion on whether a zoning proposal affects a Ch.40A eligible location.
