For additional requirements of public buildings, theaters and places of assemblage, see the Building Code.

B. 

Before the construction or alteration of any gas piping in any building or part of any building, a permit must be obtained from the Chief Building Inspector.

Small alterations may be made by notifying the Chief Building Inspector using the same blank forms provided for alterations and repairs to plumbing.
