Building codes and regulations provide for and promote the health, safety and welfare of Tumwater residents, today and into the future. City and state building codes are made up of building, fire, plumbing, mechanical (heating and air-conditioning), electrical, and sign regulations. It’s important that each new and existing structure comply with these codes to ensure equal and safe access for everybody. The Washington State Building Code is comprised of several different codes. Most are national model codes adopted by reference and amended at the state level. Others, such as the Washington State Energy Code, are state-written state-specific codes.  Local jurisdictions are required to adopt these codes for application in their jurisdiction.
