How Subdivision Rules Shape Development
Subdivision rules decide how land can be divided, what streets and utilities the developer builds, and what goes on the recorded plat.
In Houston, where there is no zoning, those rules carry even more weight.

Houston: Chapter 42
Houston's Planning Department states that the City does not have zoning, but development is governed by ordinance codes
Chapter 42 sets subdivision and platting rules, including rights-of-way and building lines
State platting authority comes from Texas Local Government Code Chapter 212
North Carolina: G.S. 160D
Chapter 160D, Local Planning and Development Regulation, defines subdivision as the division of land for sale or development as specified in G.S. 160D-802
Counties and towns adopt their own subdivision ordinances under that framework
Florida: Chapter 177 and Local Codes
Florida Statutes Chapter 177, Land Boundaries, Part I, covers platting
Local land development codes set lot, street, drainage and utility standards
What Every Subdivision Plan Needs
A boundary and topographic survey (by others)
Street, lot and easement layout
Drainage design, including a detention pond or regional credits where allowed
Water and sewer extensions, or approved private systems
Floodplain review where lots touch a mapped flood zone
