Allowable Height, Area and Number of Stories Calculator

After several weeks of working on this, I'm excited to release a beta version of the 2015 IBC Allowable Height, Area and Number of Stories Calculator. Take a look and let me know what you think!

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 full frontage increase. You'll need to do your own exact frontage calculation if needed.
