Summary
Clarkstown does not mandate sprinklers in one- and two-family homes, but where a sprinkler system is installed under a building permit, order or law, it must be kept operative and inspected under a strict semiannual testing schedule enforced by the Chief Fire Safety Inspector.
Sprinkler systems, standpipe systems, fire-detection systems and other fire-protective or extinguishing systems and other fire safety devices which have been installed as a requirement of a building permit, order or because of any law or ordinance shall be maintained in operative conditions at all times. It shall be unlawful for any owner or occupant to reduce the effectiveness of the protection so required... Sprinkler systems shall be inspected and tested in accordance with the National Fire Protection Association Standard for the inspection, testing and maintenance of Water Based Fire Protection Systems (NFPA 25), but not less than on a semiannual basis.
Full Breakdown
" The detailed bulk requirements are set out in a fire prevention chart kept as an attachment at the end of the chapter. Once a sprinkler system exists because of a building permit, order or ordinance, § 143-27A makes it "unlawful for any owner or occupant to reduce the effectiveness of the protection so required," except for temporary shutdowns to make tests, repairs, alterations or additions, and the Chief Fire Safety Inspector must be notified in advance if that work will run longer than 24 hours.
Section 143-27B(1) requires sprinkler systems to be inspected and tested under NFPA 25 "but not less than on a semiannual basis," with control valves inspected monthly, gauges checked monthly and with an inspector's gauge every five years, water-flow alarms tested quarterly, and full system flushing every five years. Written test and maintenance reports must go to the Chief Fire Safety Inspector's office within five days of the work.
Violations & Fines
Reducing sprinkler protection without authorization, or failing to maintain, test or report as required by § 143-27, is a violation of Chapter 143 punishable under § 143-6: up to $2,500 for a first offense (fine, up to 15 days imprisonment, or both) and up to $5,000 or up to a year for any subsequent violation, with each day of continued noncompliance treated as a separate offense.
