The present disclosure describes system and methods for determination of building code performance. One such method comprises performing design model validation, wherein design model validation comprises entering building permit application file information and checking the building permit application file information against relevant codes and regulations, using a taxonomy or neural natural language processing techniques or artificial Intelligence; performing exchange model code checking, wherein exchange model code checking comprises using a plurality of exchange models; performing code conformance checking, wherein the code conformance checking comprises receiving a request from the exchange models and passing the building permit application file information to code checking modules configured to check building code provisions and one or more regulations per local, state, national or international requirements; performing verification reporting based on input provided from the code checking modules; and performing results reporting based on findings of the verification reporting. Other methods and systems are also provided.
