Automated water closet compliance analysis with interactive user feedback

An apparatus for analyzing water closet compliance with a relevant building code, the apparatus comprising:

• a controller comprising a processor and a digital storage, the digital storage comprising executable software code, executable upon command to cause the processor to:
• receive a design plan of at least a portion of a building;
• represent a portion of the design plan as multiple dynamic components, wherein the multiple dynamic components comprise one or more of:
• a line, a polygon, a vector, a wall symbol, a door symbol, and a fixture symbol;
• generate a first interactive user interface comprising at least some of the multiple dynamic components representing the portion of the design plan, each dynamic component including a parameter changeable via the first interactive user interface;
• identify a water closet area as a part of the portion of the design plan, wherein the identification comprises recognizing one or more fixtures, including a water closet, and detecting a location and boundaries of the water closet area within the portion of the design plan based on recognizing the one or more fixtures;
• ascertain at least one design parameter associated with one or both of:
• the water closet area, and the one or more fixtures;
• compare the ascertained at least one design parameter against a set of conditions relating to water closet compliance;
• and
• indicate in the first interactive user interface whether the building is in compliance with the set of conditions relating to the water closet, or not in compliance with the set of conditions.
