Clay County Green Building Code

In 2010, Clay County adopted by reference with 1 amendment ICC 700 National Green Building Standard™ (NGBS).  Click here to see the County Commission Ordinance approving the Clay County Green Building Code (2010-ORD-33).  It is important to note that the Clay County Green Building Code is voluntary, not mandatory for all construction.

Information about NGBS

The National Association of Home Builders (NAHB) and the ICC partnered to establish a much-needed and nationally-recognizable standard definition of green building in 2007.

The resulting NGBS is the first and only residential green building rating system to undergo the full consensus process and receive approval from the American National Standards Institute (ANSI). The Standard defines green building for single- and multifamily homes, residential remodeling projects, and site development projects while still allowing for the flexibility required for regionally-appropriate best green practices.
