Where structural conditions impose extreme difficulty in fully complying with the plumbing regulations of this chapter, any aggrieved party may apply in writing to the building inspector for special permission to deviate from the regulations. If, in the judgment of the building inspector, such deviation is reasonable and does not create an unsanitary or unsafe condition, he shall recommend to the city council that the request for deviation be approved or disapproved, or that approval is subject to such conditions as the city council may require. The city council, on review, may approve or disapprove the application or vary the conditions on which approval is granted. (1982 Code § 9-564; amd. 2003 Code)
