New York Public Functions With Attendance Over 5,000 People — 10 NYCRR Part 18 (§ 18.4 bands) with Subpart 7-4 Mass Gatherings[1]
Summary
New York's State Sanitary Code Part 18 governs any "scheduled or advertised event open to the public and likely to attract 5,000 or more people at any one time." No person may hold or promote such a public function without a permit from the State Commissioner of Health or designee; the application is due at least five days before first advertising and at least 30 days before the event, and must include an emergency medical services operational plan. Section 18.4 sets quantitative bands: at 5,000–15,000, one on-site emergency health care facility staffed by two EMTs, one on-site ambulance with at least one EMT, and "services of a physician available to the site within 15 minutes"; at 15,001–30,000, two facilities with two EMTs each; at 30,001–50,000, two facilities and two ambulances with "a physician onsite"; over 50,000, three ambulances and a physician on site. Sponsors keep patient records for seven years, and § 18.6 compels additional resources when actual attendance exceeds the estimate by more than 20 percent.
So what
New York is a true statutory-band state: at 5,000 projected attendance the EMS operational plan, EMT-staffed facility counts, ambulance counts and the 15-minute-versus-on-site physician tier become mandatory permit conditions enforceable by DOH, so staff to the band rather than to judgment. The 20 percent surge clause means the plan must carry a documented escalation trigger and a named source of additional units. For overnight events, Subpart 7-4 (5,000-plus for 24 hours or more) adds a separate permit and pulls Part 18 §§ 18.3 and 18.4 in by reference, together with a general duty of "adequate medical and nursing supervision and care."
