Boston’s building-permit process is primarily administered by the Inspectional Services Department (ISD). The department handles building permits, inspections, zoning compliance, and related approvals through its online permitting system. For construction work, Boston distinguishes between Short-Form permits for many minor alterations and Long-Form permits for larger projects or work that changes a building’s structure or use.
A building permit may be only one part of the approval process. Depending on the property and scope of work, an application can require additional review for zoning, work near parks or parkways, or historic preservation. If a proposal does not conform to the Boston Zoning Code, the applicant may need to pursue relief through the Zoning Board of Appeal before the underlying permit can move forward.
Boston’s historic building stock creates another important layer of review. The Boston Landmarks Commission and the city’s historic district commissions review proposed changes to designated landmarks and properties within local historic districts. Their approval is separate from the standard building-permit process and may be required before Inspectional Services can issue a construction permit.
Permitting responsibilities also extend beyond ISD. For example, street occupancy, excavation, and certain driveway permits are handled through Boston Public Works. Applicants planning a project can start with the City’s Boston Permitting resource, then follow the appropriate department and application process for the specific work involved.
