The bill establishes "drug-free homeless service zones" in Iowa, which are defined as areas within three hundred feet of facilities that provide services to homeless individuals and receive government funding. It prohibits individuals from selling, transferring, or attempting to sell controlled substances within these zones. Additionally, it makes it illegal for operators of these facilities to allow individuals accessing their services to possess or use controlled substances on the premises. Violations of these provisions carry significant penalties, including increased prison sentences and fines.

Specifically, individuals caught selling or attempting to sell drugs in these zones face enhanced penalties, including a minimum one-year increase in their sentence compared to existing laws. They are also ineligible for deferred judgments or probation. Operators who violate the rules regarding substance use on their premises are guilty of an aggravated misdemeanor and face a three-year ban from applying for state homelessness assistance grants. The bill also mandates that operators display clear signage identifying the facility as a drug-free zone, ensuring public awareness of the regulations in place.
