House Bill No. [insert number] aims to enhance the regulations surrounding the renovation of public properties within historic preservation districts in Louisiana. The bill introduces a new section, R.S. 25:747, which mandates that any restoration, renovation, or construction work exceeding $200,000 on the exterior of state, parish, or municipal properties designated as landmarks or contributing rated structures must adhere to specific guidelines. These guidelines include compliance with the Department of the Interior's standards and the requirement for a certificate of appropriateness as outlined in existing law (R.S. 25:738). Additionally, the bill defines "contributing rated structures" and "project" to clarify the scope of its application.

Furthermore, the bill stipulates that prior to commencing any such project, the relevant state or local authorities must notify the legislators representing the district and the local historic district commission. The commission has the discretion to review the project, and if it chooses to do so, a public hearing must be held to gather community input. The bill also allows local historic district commissions to issue stop orders or file lawsuits against projects that do not comply with the new regulations. Importantly, the provisions of this bill will only apply to projects initiated after August 1, 2025, and do not cover emergency repairs aimed at preventing further damage to historic structures.
