The "Anti-Fungi Act of 2025" amends existing landlord and tenant laws in Oklahoma, specifically 41 O.S. 2021, Section 118. The bill mandates that landlords must make repairs in a timely manner and specifically addresses the presence of mold in rental properties. If mold is reported, landlords are required to initiate treatment within three business days and complete it within seven business days. Additionally, the bill introduces penalties for landlords who fail to comply with these mold treatment requirements, including covering tenant medical bills related to mold exposure and imposing fines of up to $1,000.

The bill also updates the language regarding the responsibilities of landlords, changing references from "his" to "the" to ensure gender neutrality. It retains existing provisions about maintaining the habitability of rental units and the disclosure of any prior methamphetamine contamination. The act is set to take effect on November 1, 2025, and includes a provision for noncodification, meaning it will not be added to the Oklahoma Statutes.
