Section 28.04 - Determination of Applicable Rate(1) For electric and gas service to its common areas and/or facilities, a condominium may be charged on a rate that is no higher than the residential rate. Therefore, a condominium may elect to be billed for its common areas and/or facilities on either the residential rate or any lower commercial rate. A condominium may, upon written request to the gas or electric company, have this billing status changed from residential to commercial, or from commercial to residential. Such condominium cannot request a change in billing status for a period of twelve months after its last request. A utility company must supply to a condominium, upon request, an analysis of the difference in charges to the condominium under each available rate or rate combination. A requested change in billing status shall be effective 30 days after receipt of the request by the gas or electric company, or one year after the effective date of any previous change in billing status, whichever is later.(2) In the case of outdoor lighting service where the gas or electricity consumption is not metered, such outdoor lighting service may be charged at a rate which includes a charge for lighting equipment provided by the gas or electric company.
