Subdivision of a large tract of land is primarily controlled by

Building codes are regulations that set minimum standards for construction and safety of buildings. While important for ensuring safe structures, they do not govern the subdivision process itself, which is primarily focused on the division of land into smaller lots rather than the specifics of building design and safety.

While the local market's needs can influence land development and subdivision projects, they do not have formal control over subdivision practices. Market demand may guide developers but it is the laws and ordinances that ultimately regulate how land can be subdivided.

The Interstate Land Sales Full Disclosure Act primarily addresses the sale of land across state lines to protect consumers, but it does not directly regulate the subdivision of land. Local and state laws play a more critical role in the actual subdivision processes, making this federal law less relevant in this context.
