Some useful definitions:

A set of standards established and enforced by local government for the structural safety of buildings. (WordNet Search)

Laws, usually but not always enacted by local government units, that set safety and fire protection standards. These codes affect the materials and methods used in the construction of buildings. For example, a code provision might require sprinkler systems in motel rooms.
