The bill enacts R.S. 33:4887, which grants municipalities the authority to establish a privilege against multifamily residential properties for unpaid sewage disposal and water system service charges. This privilege applies specifically to properties utilizing a master meter service agreement, where a single meter measures the total water or sewage usage for multiple units. The bill outlines the process for municipalities to collect these unpaid charges, including the requirement for written demand to the property owner through various methods such as mail, electronic communication, or hand delivery. The owner is given a thirty-day period to make payment after receiving the demand.

If the payment is not made within the specified timeframe, the municipality can file a sworn detailed statement of privilege, which secures the unpaid charges and any accrued interest. This statement must include specific information such as a complete property description, the owner's name, the amount owed, and the date of the written demand. The privilege becomes effective upon filing the statement in the mortgage records and takes precedence over other rights that arise after its recordation. The bill aims to streamline the collection process for municipalities and ensure they can effectively enforce their rights to collect unpaid service fees.
