Which codes and exemptions should I review?
Massachusetts State Building Code 780 CMR Tenth Edition with Massachusetts amendments, Nantucket zoning and historic-district requirements, and applicable electrical, plumbing/gas, mechanical, fire and accessibility codes. Nantucket enforces the Massachusetts Stretch Energy Code for new residential dwellings and large commercial projects; its 2025 checklist identifies IECC 2021 with key Massachusetts amendments, including 225 CMR Chapters 22 and 23. Nantucket requires a building permit for regulated construction and maintains a separate $50 zoning permit category for sheds up to 200 square feet, so zoning review can still apply to small accessory structures. Ordinary repairs and minor cosmetic work that 780 CMR exempts may not require a building permit, but specialized electrical, plumbing/gas, historic-district, zoning, conservation or other approvals can still be required; confirm with PLUS before starting.
