TowerGuard NYC
A compliance app for NYC building managers that tracks every cooling tower and hot-water heater in their portfolio, scores Legionella risk from quarterly test results, and lights up the moment an outbreak pops up inside your radius.

- One-click audit packet (test logs, maintenance logs, certifications) exportable to PDF for DOHMH inspectors
Two more deaths in the active Manhattan outbreak are pushing 500+ Google searches this week, and DOHMH is actively canvassing cooling towers right now — the compliance angle is permanent under Local Law 77 but the outbreak gives a sharp acquisition push.
Confirmed 2025 Central Harlem outbreak (118 cases, 7 deaths per NEJM) plus active Upper East Side cluster per NBC NY; ~5,000 NYC cooling towers under LL77 and NYC just doubled testing cadence — sharp, time-boxed acquisition window.Outbreak of Legionnaires' Disease Associated with Cooling Tower Systems, Central Harlem, July–August 2025 ↗What to know about Upper East Side Legionnaires' disease cluster - NBC New York ↗
Vitralogy is already a purpose-built NYC-only LL77 compliance tool with ~200 building managers; Ecolab/Nalco vendor portals and generic CMMS (Corrigo, UpKeep, MaintainX) cover adjacent needs. Outbreak-radius alerting is a real differentiator but the core compliance wedge is taken in NYC.Cooling Tower Legionella Compliance SaaS for Building Owners and Water Treaters ↗
Vitralogy proves willingness to pay at ~$6,000/year per multifamily building; NYC fines up to $25,000/violation and possible jail time create urgency; SaaS pricing model of $200–500/building/month is benchmarked and credible.Cooling Tower Legionella Compliance SaaS for Building Owners and Water Treaters ↗NYC Cooling Tower Compliance: Your Guide to Local Law 77 & 159 ↗
LL77 is permanent city law; LL159 (effective May 8, 2026) tightens testing from every 90 days to every 31 days; ASHRAE Standard 514 (adopted July 2024) expands scope nationally; CDC reports ~10.4% annual case growth since 2003 — regulatory tailwind is multi-decade.LL77 — NYC compliance guide | LLDesk ↗NYC Cooling Tower Registration Info & Services ↗
NYC DOHMH already publishes a public cooling tower registry and GIS data, and Lab/ASHRAE compliance rules are well-documented — core app build is moderate, but live outbreak-alert feed integration with DOHMH alerts and lab turnaround data adds meaningful complexity.NYC Health — Cooling Tower Registration and Maintenance ↗LL77 — NYC compliance guide | LLDesk ↗
