Substitute House Bill No. 5505 introduces regulations for the use of commercial warehouses as housing or shelter, requiring individuals or entities to obtain a municipal permit if they intend to use a warehouse for more than 24 hours for these purposes. The bill mandates that municipalities conduct public hearings on permit applications and ensures compliance with health and safety standards, including access to sanitary facilities, potable water, and adequate sleeping accommodations. Municipalities are granted the authority to revoke permits for violations and can opt out of the permitting requirement through a vote. The bill also includes exemptions for warehouses already in use for housing prior to its passage and allows for temporary shelters during emergencies.

The legislation defines "commercial warehouses" as buildings over 25,000 square feet designed for the import, storage, or distribution of goods. It requires that applicants demonstrate adherence to specific health and safety standards, including adequate space and facilities, and compliance with state building, fire prevention, and public health codes. Each municipality will appoint a designated individual or board to review applications, which must be publicly notified to neighboring property owners within three business days. The bill aims to ensure safe living conditions for individuals housed in commercial warehouses while providing municipalities with the necessary regulatory authority.
