Overview of Rules

Storage rules cover container types, maximum allowable quantities, approved cabinets or rooms, segregation of incompatible materials, labeling, ventilation, and spill-control measures. Many storage limits and operational controls are set by the New York City Fire Code and enforced by the Fire Department of New York (FDNY) together with building inspectors.

Penalties & Enforcement

Enforcement is primarily by FDNY inspectors and, where building occupancy or structural issues arise, by the Department of Buildings (DOB). Specific fine amounts for flammable-material storage violations are not specified on the cited FDNY page; the FDNY page identifies permit and compliance requirements but does not list exact penalty figures or escalation tables.^[1]

Failure to comply can result in orders to stop hazardous operations until corrections are made.
