What NYC Department of Health and Mental Hygiene does

The NYC Department of Health and Mental Hygiene (DOHMH) is the municipal public health authority for New York City, established in 1866 and headquartered in Queens. It serves the city's 8 million+ residents through a portfolio of regulatory, surveillance, and direct service functions, including disease outbreak control (notably Legionnaires' disease, COVID-19), food and water safety inspection, child care facility regulation, cooling tower oversight, health insurance enrollment, and emergency preparedness. The agency is led by Health Commissioner Dr. Alister Martin (appointed March 2026) and operates with 5,001-10,000 staff under the authority of the City of New York.

DOHMH's primary technology platform is NYC311, a multi-channel civic engagement system operated in conjunction with the NYC Office of Technology & Innovation. NYC311 delivers 24/7 service access via phone (311 / 212-639-9675), text (311-692), mobile applications (iOS/Android), web portal, and social media, supporting 175+ languages. The platform has handled 500 million+ customer interactions since its 2003 launch, connects to 200+ city agencies and non-profits, and accepts 500+ types of service requests. A public API suite (NYC311 Public API, Geoclient API, Event Calendar API) and NYC Open Data extend the platform's machine-readable footprint, while a new public health laboratory is being established to strengthen disease detection.

All DOHMH services are provided free of charge to NYC residents; the agency is funded through city budget allocations and federal public health grants rather than commercial revenue. Recent strategic posture is shaped by federal funding cuts to the Essential Plan, prompting a joint effort with NYC Health + Hospitals and the New York State of Health Marketplace to protect 200,000+ residents from losing coverage, alongside expanded multilingual outreach and a $15 million gender-affirming care plan. Active enforcement actions and lawsuits tied to the 2025 Harlem Legionnaires' outbreak and the 2026 Upper East Side outbreak underscore the agency's regulatory mandate and its exposure to litigation risk.
