** The occupancy classification for any project, not included in this list, shall be
determined through the following process:
i. The functional requirements of the unidentified occupancy shall be compared with
the Occupancy use type, classification, sub-classification categories and
descriptions to match with the given occupancies to find the most similar
Occupancy,
ii. If process (i) fails to determine the Occupancy, the project will be referred to the
Board of Appeal constituted as per directives of Part 2 Chapter 2. The Board of
Appeal shall determine the Occupancy, and
iii. The decision of Board of Appeal shall be considered as an explanatory material of
this Code and shall be added as addendum to this Code. For any future projects of
similar nature this addendum will suffice and need not be referred to the Board of
Appeal again.
