The 2006 Washington State Building Code, Chapter 51-50 WAC, outlines the adoption and enforcement of the International Building Code (IBC) along with other related codes to ensure standardized building regulations throughout the state. This code is crucial for maintaining safety, accessibility, and environmental health in building practices. Initially adopted in 1974 by the Washington State Legislature, the responsibility for its adoption and amendments was transferred to the State Building Code Council in 1985.
The code specifies a hierarchy of precedence among various documents, ensuring that in case of conflicting regulations, the one listed earlier takes priority. For example, discrepancies between the mechanical code’s duct insulation requirements and those of the Energy Code are resolved in favor of the latter or an applicable local jurisdiction’s energy code. Additionally, if different sections of the code specify different materials or construction methods, the most restrictive regulation prevails.
Enforcement of the code is mandated for each local jurisdiction, which may contract out these responsibilities to other jurisdictions or agencies. Amendments to the code are reviewed annually, with proposals for amendments accepted on specific forms and by a set deadline each year. While local jurisdictions can amend the code, such amendments cannot diminish the minimum performance standards and are restricted in areas like residential energy provisions and accessibility standards.
The code also addresses specific exclusions, such as temporary structures used for horticultural purposes or temporary worker housing, which are governed by different regulations. The effective implementation of the code is scheduled for July 1, 2007, ensuring all counties and cities within the state comply. Additionally, provisions for the storage of recyclable materials and solid waste in new buildings are mandated, enhancing environmental considerations in building practices.
