No. 87-100 (on area separation walls and sprinkler systems in buildings exceeding 10,000 square feet) to new buildings only. Pursuant to directions from the Board on 2-28-89, attached is a copy of the subject ordinance.

No. 87-100's prohibition against openings in area separation walls unless the entire building is installed with a sprinkler system to new buildings only, and not to additions to or alterations of existing buildings. 2 . Applies Ord. No. 87-100's requirement that buildings exceeding 10,000 square feet in size be installed with a sprinkler system to new buildings only, and not to additions to or alterations of existing buildings . 3 . Requires sprinkler systems in "buildings" exceeding 20,000 square feet in total floor area irrespective of separation or compartmentalization by area separation walls without openings . 4 . Specifies that new buildings are those issued building permits on or after the effective date of this ordinance, and includes a building replaced after it has been substantially destroyed in the opinion of the building inspector. 5 .
