Decks & Porches in Millbury, Massachusetts

Mass Save rebates are for energy equipment and weatherization, not deck construction. National Grid serves Millbury for electricity, so residents are eligible for Mass Save for qualifying home energy improvements. For deck projects, the governing framework is the Millbury Building Department under 780 CMR. The Blackstone River corridor and its associated wetlands create Conservation Commission jurisdiction for properties within 100 feet of the river bank or any mapped wetland. Given the town's industrial canal heritage, some lower-lying lots near the Blackstone also have floodplain considerations. The 61-year-old median home age means many existing decks in town predate current ledger-flashing requirements and may have guardrails below the current 36-inch minimum.

File with the Millbury Building Department under 780 CMR. Any attached deck requires a building permit with footing and framing inspections. Properties within 100 feet of the Blackstone River, its tributaries, or any mapped wetland need a Notice of Intent reviewed by the Millbury Conservation Commission before the building permit issues. Footings must reach 48 inches below grade. Guardrails on surfaces 30 or more inches above grade must be at least 36 inches tall with baluster spacing under 4 inches.
