    Fire code permits are required for a variety of activities, including bonfires, welding and cutting operations, and the use and storage of certain hazardous materials. The municipal fire official is responsible for the enforcement of the fire code permit system, which consists of taking permit applications, collecting fees, issuing permits, and inspections. The University Fire Marshall provides assistance to departments in the interpretation of the fire code.

Scope and Application

    The New Jersey Uniform Fire Code permit requirements apply to a wide variety of activities including bonfires, cutting and welding activities, and the use and storage of certain hazardous materials, such as radioactive materials, combustible and flammable liquids, cryogenic liquids, explosives, oxidizers, organic peroxides, flammable solids, and compressed gases. Departments where these activities take place are responsible for complying with the fire code permit requirements.

Program Description

    Departments may be located in one or more of three municipalities including Princeton Borough, Princeton Township, and Plainsboro. While the fire code permit process varies slightly from one municipality to another, the following steps are typically required by all.

    Hazardous Materials Inventory

    A hazardous materials inventory must be completed for each building a department occupies. The inventory form, along with instructions for its completion, is provided by the municipal fire official. From the inventory data, determine which fire code permits are required.

    Fire Code Permits

    There are five types of fire code permits, each covering a variety of workplaces and activities. Two of the five permit types typically apply to operations at the University. A Type I permit is required for activities such as bonfires, cutting and welding operations (see Section B10, Cutting and Welding), open flames in places of assembly (see Section A5, Places of Assembly), and storage and handling of small quantities of flammable liquids. A Type IV permit is required for hazardous materials such as corrosives, oxidizers, cryogenic liquids, compressed gases, radioactive materials, and flammable liquids when the aggregate quantity of any category stored or handled exceeds the threshold amounts specified in the fire code. The other types of permits include Type II, required for activities such as carnivals, circuses, and fumigation for insects, Type III, required for industrial furnaces and the storage of fireworks, and Type V, required for airports. Permit application forms are available through the municipal fire official. Assistance in determining applicability of the code is available through the University Fire Marshall.

    Posting Fire Code Permits

    Fire code permits must be posted according to the municipal fire officials instructions, which vary for each municipality. Failure to obtain or post permits or to comply with fire code requirements may subject the department to fines or other penalties.


    The municipal fire official may inspect operations covered by the fire code permits. These inspections focus on compliance with the New Jersey Uniform Fire Code.
