The Heights and Areas (H&A) Calculator is a joint effort of the American Wood Council, WoodWorks – The Wood Products Council, 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 2015 editions of ICC’s International Building Code® (IBC®) provisions. Input a given building geometry, site conditions (e.g., open frontage), type of construction and occupancy, and allowable heights and areas can be determined. Links to download Android, iOS and MS Windows versions are shown on this page. Additional resources for wood building design and construction are outlined below.

AWC supports the utilization of wood products by developing and disseminating consensus standards, comprehensive technical guidelines and tools for wood design and construction, as well as providing education regarding their application. Contact AWC via email: or connect with one of AWC’s regional building code experts.
