Amends GS 62-110(g), which authorizes the Utilities Commission (Commission) to adopt procedures that allow a lessor to charge for the costs of providing water or sewer service to persons who occupy leased premises. Provides that if the Commission approves a flat rate for water or sewer services for contiguous dwelling units rather than a rate based on metered consumption, the lessor can pass through and charge the tenants of the contiguous dwelling units the same flat rate for water or sewer services and the administrative fee authorized by existing subdivision (g)(2). Requires bills for water and sewer service sent by the lessor to the lessee to contain all of the information required by sub-subdivisions e.2 through e.5 of subdivision (1a), including: the method used to determine the amount of water and sewer services allocated to the lessee; beginning and ending dates for the billing period; the past-due date, which cannot be less than 25 days after the bill is mailed; and a local or toll-free telephone number and address that the lessee can use to obtain more information about the bill.
