Full Breakdown

Suffolk County Code § 704-18 requires every retail store in the county that sells swimming pools to post a sign, in the form the Commissioner of Consumer Affairs prescribes, telling customers that pools deep enough to require an alarm under New York Executive Law § 378(14) and 19 NYCRR § 1228.2 must have one installed. The law covers in-ground, aboveground, indoor, and inflatable pools, hot tubs and spas holding water more than 24 inches deep. The Suffolk County Department of Consumer Affairs enforces the posting rule and sets the sign's size and wording.

Violations & Fines

Selling or offering swimming pools without the required alarm-notice sign draws a $500 civil fine for a first violation and $1,000 for each later violation, per § 704-21.

Frequently Asked Questions

Does Suffolk County require pool alarms itself?
No: the alarm mandate comes from New York Executive Law § 378(14) and 19 NYCRR § 1228.2; the county's own rule requires retailers to post a sign telling buyers about that state requirement.
Which pools are covered by the sign requirement?
Any pool, hot tub, or spa capable of holding water more than 24 inches deep, including inflatable, aboveground, in-ground, and indoor pools.
