Short-form or long-form building permit check for window or exterior door work

Boston's window guide says replacing an existing window requires a short-form permit when no structural changes are needed, while creating a new window or making structural changes such as opening a wall or expanding the window size requires a long-form permit. Window and exterior door work should be checked with Inspectional Services because opening changes, egress, structural work, exterior appearance, landmark review, or larger alterations can change the permit route.
