The bill amends Section 2 of Act 634 from the 1951 Regular Session, which pertains to zoning regulations enforced by county commissions in counties with populations of 400,000 or more. Key changes include the rephrasing of legal language for clarity, such as replacing "such" with "the" and "Act" with "act." The penalties for violations have been updated to classify them as Class B misdemeanors, with each day of continued violation considered a separate offense. Additionally, the bill mandates that the County Building Commissioner or their agent must provide written notice of violations before pursuing criminal prosecution.

Furthermore, the bill enhances the authority of the Building Commissioner by allowing them to take legal action, including injunctions and mandamus, to address violations of zoning regulations. The Commissioner is also granted the ability to intervene in legal proceedings related to these violations, ensuring they are treated as original parties in such cases. The act is set to take effect immediately upon passage and approval by the Governor.
