Bill No. 2147, titled the "Municipal Code Lien Enforcement Act of 2025," establishes a framework for municipalities in Oklahoma to enforce housing and building code violations through the imposition of liens on real property. The bill defines key terms such as "municipal code lien," "owner-occupied," and "interested party," and specifies that the provisions apply to all municipalities, with an exception for owner-occupied properties. Municipalities are authorized to initiate judicial in rem foreclosures of these liens, which allows them to pursue property without holding the owners personally liable. The bill outlines the necessary procedures for municipalities to follow, including the requirement to enact an ordinance or resolution to utilize these enforcement mechanisms.

The act mandates that municipalities must utilize judicial in rem proceedings as the sole remedy for enforcing municipal code liens, and it sets forth specific requirements for filing petitions for foreclosure, including notice requirements to interested parties. The bill also stipulates that municipal code liens will be superior to all other liens, except for tax liens, and it provides a timeline for municipalities to notify other taxing agencies prior to filing for foreclosure. The act is set to take effect on November 1, 2025.
