IBC Allowable Height and Area Calculator (Non-Separated Mixed Occupancy)

**Updated - You can now choose between the 2015, 2018 and 2021 IBC

A few notes:
  • Calculator is for single occupancy or non-separated mixed occupancy buildings. Separated mixed-occupancy functionality is coming later.
  • There are some error notes that I've programmed in (for example, using an NFPA 13R sprinkler system in a non-residential occupancy), but the calculator is not foolproof. Some background code knowledge is needed.
  • Allowable area results are displayed for no frontage increase and a full frontage increase.
