File with the Kingston Building Department under 780 CMR. Any attached deck requires a building permit with footing and framing inspections. Properties within 100 feet of Kingston Bay, Jones River, coastal bank, salt marsh, or any mapped wetland need a Notice of Intent reviewed by the Kingston 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.

Deck costs in Kingston and the South Shore Plymouth County market run in the mid-to-upper range for Massachusetts. A 300-square-foot pressure-treated deck on a Kingston colonial typically costs $14,000 to $21,000 installed. Composite decking (Trex, TimberTech, Azek) at that footprint runs $21,000 to $33,000. Coastal salt air from Kingston Bay and Plymouth Bay makes composite and PVC a strong long-term value for ocean-facing or bay-adjacent properties. Conservation Commission filings add $500 to $1,500 and four to six weeks to the schedule.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential decks & porches work; ask for the registration number and check it before paying a deposit.
