Fire Suppression and Fire Alarm Systems

​​The Division of Industry Services (DIS) Fire Suppression and Fire Alarm Systems Program includes all fire protection systems. Rules are administered pertaining to fire protection systems. There are credentials administered for automatic fire sprinkler system workers, according to SPS 305 Licenses, Certifications, and Registrations. Fire protection system plan review is offered. See also Fire Prevention, Fire Department Safety and Health, and ​Commercial Buildings Programs.

DIS coordinates with local certified municipalities and/or fire departments that provide plan review and inspection services for certain types of buildings. To become a local certified municipality, please visit the Delegated Agents page.

Questions regarding fire protection systems can be sent to DSPSSBFireProtech@wisconsin.gov.


2023 Winter Code Updates

Wisconsin's regional inspector associations, in cooperation with Wisconsin Code Officials Alliance and the Wisconsin Department of Safety & Professional Services, are offering virtual and in-person training sessions in early 2023 about Wisconsin's Electrical Code, Uniform Dwelling Code, Plumbing Code, and Commercial Building Code.  These courses can provide continuing education credits for Industry Services administered inspection and Dwelling Contractor Qualifier (DCQ) credentials.  Fire inspectors, designers, contractors, and others with an interest in Wisconsin’s codes may also benefit from the programs.

Registrations for all courses will be online using the following link: https://www.eventsquid.com/event/18752

2013 Act 270 Grandfathered Ordinances

2013 Act 270 establishes a uniform commercial building code in Wisconsin, while allowing municipalities to grandfather fire detection, prevention, and suppression ordinances that relate to the construction, alteration, or addition to a public building or building that is a place of employment. An ordinance that is grandfathered has passed the requirements laid out by the Legislature in Wisconsin Statute §101.02(7r)(b).
