Heights and Areas Calculator
Use this handy calculator to determine maximum heights and areas for buildings of various occupancies and fire protection based on 2006 to 2021 editions of the IBC.
The Heights and Areas (H&A) Calculator is a joint effort of WoodWorks, the American Wood Council (AWC), and the International Code Council (ICC). It provides users with an app-based approach to calculating maximum heights and areas for buildings of various occupancies and fire protection based on 2006 to 2021 editions of the ICC’s International Building Code (IBC). Input a potential building’s geometry, site conditions (e.g., open frontage), type of construction, and occupancy, and the calculator will provide options for allowable heights and areas.
This calculator is not meant to be a replacement for the IBC and does not encompass all of its design options. The IBC should always be consulted for specific requirements related to designs and site conditions.
