Chapter 5 of the 2018 International Building Code regulates building height and area limits based on the occupancy type and construction classification. The code permits increases in these limits when certain conditions are met, such as open frontage for fire department access, separation, and the presence of sprinkler systems. The thresholds for building size are detailed in Tables 504.3, 504.4, and 506.2, which consider the group classification, allowable heights and areas, and types of construction. Additionally, unlimited area buildings are allowed in specific occupancies if they meet special provisions outlined in Section 507.
