In New York, a clean pool
isn't a luxury.
It's a legal requirement.
We've kept 340+ commercial properties violation-free since 2016.
A single DOH Article 165 violation can close your rooftop deck in July. Chlorine deploys a fleet of certified technicians across Manhattan, Brooklyn, and Long Island — treating every service call as a pre-inspection audit.
One testimonial is a story.
Twelve is a pattern.
Property managers, hotel GMs, and fitness operators — all of them switched providers after a close call with the DOH.
They caught our filtration issue before the inspector did. We had a DOH audit three weeks later — passed without a single comment.
Our rooftop pool is open June through September. Missing a single weekend is $40,000 in lost revenue. Chlorine has never once put us in that position.
What triggers an immediate closure
Under Article 165, a DOH inspector can issue a Summary Suspension Order on-site if free chlorine falls below 0.6 mg/L, combined chlorine exceeds 0.5 mg/L without corrective action, or any cyanuric compound is detected. Reopening requires written departmental authorization — not just a corrected reading.
⚠ Summary Suspension: Facility closed until DOHMH authorizes reopening
Members notice the second the water turns cloudy. I stopped getting complaints the month we switched to Chlorine.
We manage 11 residential pools across four boroughs. Chlorine coordinates all of it. One point of contact, one invoice, zero violations.
Every service we perform is engineered around a specific line of the NYC Health Code — because vague maintenance doesn't hold up in a DOH inspection room.
Bathing Establishments: The permit that governs your pool
Every commercial pool in New York City — hotel rooftops, condo amenity decks, fitness club lap pools — operates under Article 165 of the NYC Health Code. The permit, issued by DOHMH, costs $1,980 to obtain and $245 annually to renew. Operating without one, or after a suspension, carries criminal liability for the property owner.
Chlorine assigns a certified pool operator to every property we service. That operator is legally accountable for chemical balancing, equipment compliance, and the maintenance of a Pool Safety Plan that must be on-site and available for inspection at all times.

Legionella testing moves from quarterly to monthly in May 2026
Following the summer 2025 Central Harlem outbreak — 114 confirmed cases, 7 fatalities — the City Council passed Local Law 159, effective May 7, 2026. All cooling tower operators must now test for Legionella monthly, not quarterly. Detection above 1,000 CFU/mL triggers a mandatory 24-hour notification to DOHMH and disinfection within 48 hours.
Chlorine's service contracts include certified Legionella sampling with laboratory processing. Each test runs $400–$500 including site visit. We coordinate scheduling so your property never misses a testing window — and never faces the $10,000+ fines for non-compliance.
⚠ Positive test >1,000 CFU/mL: 24-hr DOHMH notification + 48-hr disinfection
Closing a pool wrong costs as much as running it wrong
NYC Health Code requires formal winterization procedures for outdoor pools, with documentation retained for DOH review. Improper drain-down, failure to store chemicals correctly, or leaving filtration equipment exposed to freeze cycles can void your permit for the following season.
Chlorine performs all seasonal openings and closings with written reports submitted to property management. We document water chemistry at closure, equipment condition, and the date of permit-compliant winterization — creating a legal paper trail that protects you in any DOH audit.
