Building codes are a set of regulations that builders and architects must follow when constructing or renovating a building. The codes vary from state to state but typically include safety, structural stability, and energy efficiency requirements. Building codes are designed to protect the public from unsafe buildings and to ensure that all buildings are built to a certain standard.

Anyone who plans to build or renovate a building should become familiar with the building codes in their area. A good place to start is the website for the local building department or zoning board. There you will find a list of the codes that apply to your area and information on how to comply with them.

Below you will find a list of building resources and building codes by state. These codes include each state's building/dwelling, structural, plumbing, mechanical, electrical, fire/life safety codes, accessibility codes, energy codes, and elevator codes. Remember that each city has its own specific building codes, so check with your city's municipal office to ensure your building plans are up-to-date.
