Full Breakdown
Caldwell City Code § 10-08-09-8(6)(E) requires any portable heater used in a downtown outdoor dining area to comply with the International Fire Code's rules for portable outdoor gas-fired heating appliances. The heater cannot be located inside any occupancy connected to its fuel gas container, inside a tent, canopy, or membrane structure, on an exterior balcony, or indoors. It must sit at least 5 feet from the building, at least 5 feet from combustible materials or combustible attachments to the building, and at least 5 feet from any exit or exit discharge.
Only listed and approved portable outdoor gas-fired appliances with a fuel gas container integral to the unit may be used, and each must be installed and maintained according to the manufacturer's instructions. Every heater must carry a tilt or tip-over switch that automatically shuts off the gas flow if the appliance tips more than 15 degrees, and its heating element or combustion chamber must be permanently guarded against accidental contact. These heater rules sit inside the broader outdoor dining permit standards, so a restaurant's Director-issued or case-by-case D-CB dining permit covers heater placement alongside table and chair layout, lighting, and noise compliance.
Violations & Fines
Using a heater that lacks a tip-over switch, sits closer than 5 feet to a building or exit, or is placed in a prohibited location such as a tent or balcony violates § 10-08-09-8(6)(E) and can trigger revocation of the outdoor dining permit in addition to Chapter 10's general misdemeanor penalty.
