The Blue Pages: Government, Permits & Utilities

For contractors and homeowners on Long Island. Hand-curated reference links, not businesses. Nobody pays to be here.

Before you dig, call 811. The agencies below are official sources. Links go to the agency's own page — go there for phone numbers, hours and current forms rather than trusting a reprint. Last checked September 2026.

Which town am I in?

Long Island addresses use hamlet names (e.g. "Hicksville") but permits come from the town (Oyster Bay) or an incorporated village. If you're not sure, look up the address on the county assessor's site or ask the town clerk before you file.
