Grease interceptors may only be placed inside a building in the event of a remodel of a building for which there is no space available outside of the building for a grease interceptor, or where the expected use of the property is that of a restaurant that will not cook food, but serve only prepared foods that will produce so little grease as to not require an exterior grease interceptor as determined by the Plumbing Inspector. In the event that the use of the property becomes such that an exterior grease interceptor is needed, the Plumbing Inspector may order that an exterior grease interceptor be placed on the property. All interior grease traps shall be Plumbing Drainage Institute approved with a solid waste interceptor located before the grease trap.
