Summary

Suffolk County prohibits parking any vehicle on county-owned or county-controlled property overnight, from sunset to sunrise, unless the vehicle belongs to authorized county personnel, someone attending a public function, or is specifically approved by the Commissioner of Buildings and Grounds.

City-specific rules exist: Babylon, Huntington, and Islip have their own overnight parking rules that differ from Suffolk County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

No vehicle shall be parked on County property between sunset and sunrise except vehicles of authorized County personnel and vehicles of persons attending public functions unless specifically authorized by the Commissioner of Buildings and Grounds or his authorized representative.[1] [1] Editor's Note: Section 14 of L.L. No. 5-1973, which immediately followed this section and pertained to identification tags and stickers, was repealed by L.L. No. 8-1979.

Full Breakdown

Suffolk County Code § 639-14 bars parking on any county-owned or county-controlled property between sunset and sunrise. Exceptions cover vehicles of authorized county personnel and people attending public functions, plus anyone the Commissioner of Buildings and Grounds specifically authorizes. Under § 639-1, 'County property' reaches county buildings, offices and parking fields but excludes highways and county airports, so this rule governs county lots and grounds, not public streets. Overnight parking on town or village streets is set separately by each of Suffolk's ten towns and their villages, not by the county.

Violations & Fines

Violating § 639-14 is an offense under § 639-17, punishable by a fine up to $100. Vehicles left overnight may also be removed and stored at the owner's expense under §§ 639-10 through 639-12.
