Massachusetts deck builders work under the 10th Edition MA State Building Code (780 CMR), based on 2021 IBC with MA amendments — effective October 11, 2024; sole code after June 30, 2025. Massachusetts requires building permits for new construction, additions, alterations, and most repairs through the statewide Building Code (780 CMR). Home improvement contractors must register with the OCABR. A separate Construction Supervisor License (CSL) may also be required. Licensing is handled by the Massachusetts Office of Consumer Affairs and Business Regulation (OCABR) — Home Improvement Contractor Program, and homeowners can cross-check a contractor before hiring. On the exemption side: ordinary repairs and maintenance that do not involve structural changes. A Massachusetts-specific rule most homeowners miss: massachusetts has a mandatory statewide building code: 780 CMR (Code of Massachusetts Regulations). The Boston and Worcester permit portals handle the bulk of Massachusetts deck permit submissions — if your project is in one of those cities, start there.
