What is the purpose of the program?

The public warehouse licensing program provides a valuable service to consumers of public warehousing services by obtaining compliance, through regular inspections, with the provisions of state statutes. On-site inspections ensure that the licensed facilities are suitable for the types of goods stored, and help identify facilities operating without a license.

What law does Wisconsin’s Public Warehouse Keeper program enforce?

The program derives its regulatory authority from Chapter 99 of the Wisconsin Statutes. Under the authority of this chapter, the program has promulgated one separate rule, Chapter ATCP 97 of the Wisconsin Administrative Code.

What warehouses need a license?

A license is required of a person or a company that stores for hire.

What is meant by "store for hire?"

"Store for hire" means to accept and maintain custody of the property of another person in return for consideration. "Store for hire" does not include the rental of designated storage space to a renter who has access to that space during normal business hours and who is responsible for the safekeeping of property stored in that space (refers to self storage or mini warehouses - reference Sec. 704.90, Wis. Stats.)

Common examples of businesses that are required to be licensed:

  1. A marina that provides boat storage, outdoor or indoor

  2. A furrier or dry cleaner storing clothing in the off season

  3. A farmer with an empty barn or shed offering storage for automobiles, boats, or snowmobiles

  4. A record center storing either paper or tape business records

  5. Food warehouses

  6. Moving and storage companies

  7. Agricultural and commercial products
