The bill establishes "drug-free homeless service zones" in Iowa, creating specific legal provisions and penalties for violations within these designated areas. A person is considered in violation if they unlawfully sell or transfer controlled substances while present in a drug-free homeless service zone, or if they are an operator of a facility-based service who allows individuals to unlawfully possess or use controlled substances on the premises. The penalties for these offenses include increased sentences, ineligibility for deferred judgments or probation, and fines that cannot be suspended. Additionally, operators who violate the law may lose eligibility for state homelessness assistance grants for three years unless they terminate the offending employee or volunteer.

To ensure compliance, the bill mandates that operators of facility-based services prominently display signs identifying their premises as drug-free zones, with specific requirements for language and visibility. The definition of a drug-free homeless service zone encompasses areas within 300 feet of the facility, which includes emergency shelters and transitional housing that receive government funding. The bill aims to enhance the safety and integrity of services provided to homeless individuals by imposing strict regulations on drug-related activities in these critical areas.
