Louisiana Revised Statutes Tit. 33, § 4725.1. Zoning of annexed property

A. Except as provided by Subsection B of this Section, if after August 15, 1999, a municipality annexes property the use of which is governed by a parish zoning ordinance at the time of annexation, and the annexation causes a change in the zoning classification, the parish zoning classification shall remain in effect until the owner of the property has applied for rezoning with the appropriate municipal governing authority, board or commission or for a period of six months, whichever occurs first. The municipality shall notify, by certified mail, the owner of the property of the change in zoning classification within thirty days of the date of the annexation.

B. The owner of property subject to Subsection A of this Section may waive the provisions of Subsection A with respect to his property. Any such waiver shall be in writing and shall be filed in the parish conveyance records. A municipal governing authority may prescribe the form for any such waiver or may authorize a municipal officer, agency, or employee to prescribe such form for the filing of such waivers. A municipal governing authority may adopt additional requirements for the filing of such waivers.
