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 updates the language regarding the responsibilities of landlords, replacing "his" with "the" to ensure gender neutrality.

Furthermore, the bill introduces penalties for landlords who fail to comply with the mold treatment requirements. Landlords found in violation will be responsible for covering tenant medical bills related to mold allergies or conditions exacerbated by mold exposure, as well as facing a fine of up to $1,000 payable to affected tenants. The act is set to take effect on November 1, 2025.
