On February 27, 2020, SDCI issued a code interpretation of Seattle Building Code section 1604.5, Risk Category Occupant Load Calculations. This code interpretation will help applicants calculate the building occupant load to determine the building’s risk category. The code interpretation allows a reduction in gross area for certain occupancy groups. It allows for some areas to be excluded from the calculation based on non-simultaneous occupancy. A code modification is required to use this code interpretation.

We updated a Tip on code interpretation appeals and developed a draft Directors Rule on RRIO inspection selection methods.
