Do I need a permit for deck construction or replacement in Danvers?
Most likely yes. Deck construction or replacement usually requires a permit in Massachusetts. Confirm the specifics with Danvers.
Only a deck not over 200 square feet, not more than 30 inches above grade at any point, not attached to the dwelling, and not serving a required exit door is exempt from a building permit (780 CMR 51.00 R105.2 item 10). The state's guidance chart lists decks as needing a building permit, a construction supervisor license, and HIC registration. Altering a bank, wetland, or land subject to flooding also requires a conservation commission filing (M.G.L. c. 131, § 40).
