Abstract: Computer-implemented methods and systems are provided for determining an actual maximum density capacity and/or development potential in view of the zoning code applicable to a particular location. Such methods and systems seek to overcome frustrations and alleviate other impediments that affect efficient use of zoning codes. In a first aspect, a computer-implemented system for determining development potential includes at least one input interface for receiving property information; a computer program for calculating a building envelope allowable under the zoning code and for calculating an actual maximum density capacity available for a geographic area of interest using the zoning code and additional factors affecting the area of interest. The results of at least the actual maximum density capacity calculation is provided to an output interface for displaying assessment of zoning code compliance and generating a virtual build of a building permitted under the zoning code for the site.
