AB 956 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: exempting certain agricultural warehouses from automatic fire sprinkler requirements.

AB 956 exempts specific agricultural warehouses storing crop protection products (like fertilizers and pesticides) from mandatory automatic fire sprinkler systems. It applies to warehouses designed primarily for storing these chemicals, provided they meet conditions such as using secondary containment for liquid products or using dry bulk storage. Owners must notify local fire departments about stored chemicals and update this information if changes occur. The exemption does not apply to office areas within the warehouse, changes in warehouse use, or other fire safety requirements beyond sprinklers. This bill directly affects agricultural businesses storing these products in qualifying facilities.
