Boston Inspectional Services (ISD)
Chimney rebuilds, new retaining walls over 4 feet, structural masonry, and work affecting egress typically need a permit from Boston ISD. Repointing and minor repairs usually do not.
Historic districts
Properties in Back Bay, Beacon Hill, the South End, Bay Village, and other landmark districts need Landmarks Commission approval for visible exterior changes, sometimes even repointing.
Surrounding towns
Cambridge, Brookline, Newton, and Somerville have their own building departments and historic commissions. Requirements under the Massachusetts State Building Code are similar, but procedures differ.
Who pulls the permit
A licensed contractor typically pulls the permit. Massachusetts requires a Construction Supervisor License for many structural jobs, and Home Improvement Contractor registration for residential work.
