No person shall perform any mechanical work or gas piping work without first obtaining
a permit from the city. The application for a permit shall be made to the building
official on forms provided by the building official. The building official may require
that the application include full plans and specifications for the work, and may further
require that such plans and specifications be certified by a mechanical engineer licensed
by the state. Such certification, when required, shall state that the work will not
violate any provisions of the state mechanical/fuel gas code or any other provisions
of this Code. The building official shall grant the permit upon finding that the work
will comply with the state mechanical/fuel gas code and this Code. No change in the
work for which a permit has been issued may be made without the written consent of
the building official.
