A permit shall be required for each building project, or work on a structure, as specified in these regulations, except as to changes in the interior of a building, where no building permit is required under any other provision of this code. The application form shall be submitted to, and approved by, the zoning administrator in order to conform with these regulations, before a permit is issued. Said permit may be combined on one form with a building permit required under any other provision of this code. (Ord. B-39, 1969)
