Subject of Possible Rule Making: WAC 392-343-019 DefinitionsInstructional space.
Statutes Authorizing the Agency to Adopt Rules on this Subject: RCW 28A.525.020.
Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: WAC 392-343-019 references the American Institute of Architects (AIA) Document D101, "The Architectural Area and Volume of Buildings," as the standard for calculating gross square feet. However, D101 does not clearly define how to address vertical shafts and stairwells. The office of superintendent of public instruction (OSPI) is considering revising this rule to clarify that stairwells and vertical shafts (mechanical shafts, elevator shafts, etc.) must be counted at each level of a building, excluding unoccupied basements and attics. The revision may also clarify that all double or triple height spaces (gyms, commons, etc.) must be counted only once, at the lowest level of such spaces.
Process for Developing New Rule: OSPI welcomes the public to take part in developing the rules. Anyone interested should contact the staff person identified [below].
Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication by contacting Scott Black, OSPI, P.O. Box 47200, Olympia, WA 98504, phone 360-725-6268, fax 360-586-3946, TTY 360-664-3631, email
