3 Preface Authority: The International Building Code (Chapter WAC) is adopted by the Washington State Building Code Council pursuant to Chapters and RCW. These codes were first adopted by reference by the Washington State Legislature in In 1985, the Legislature delegated the responsibility of adoption and amendment of these codes to the State Building Code Council. Code Precedence: The State Building Code Act, Chapter RCW, establishes the following order of precedence among the documents adopted as parts of the State Building Code: International Building Code, Standards and amendments -WAC 51-50; International Residential Code, Standards and amendments WAC 51-51; International Mechanical Code, Standards and amendments - WAC 51-52; International Fire Code, Standards and amendments - WAC 51-54; Uniform Plumbing Code, Standards and amendments - WAC 51-56, Where there is a conflict between codes, an earlier named code takes precedence over a later named code. In the case of conflict between the duct insulation requirements of the International Mechanical Code and the duct insulation requirements of the Energy Code, the Energy Code, or where applicable, a local jurisdiction's energy code, shall govern. Where, in any specific case, different sections of this Code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Organization and Numbering: These rules are written to allow compatible use with the International Building Code. All sections which are amended, deleted, or added are referenced. Enforcement: The State Building Code Act requires that each local jurisdiction enforce the State Building Code within its jurisdiction. Any jurisdiction can contract with another jurisdiction or an inspection agency to provide the mandated enforcement activities. Amendments to the State Building Code: The State Building Code Council has adopted review procedures and approval criteria for local amendments. These procedures and criteria are found in Chapter WAC. The Council has exempted from its review any amendments to the administrative provisions of the various codes. Forms for proposing statewide amendments to the State Building Code are available from the State Building Code Council staff. A. Amendments of Statewide Application: On a yearly basis the State Building Code Council will consider proposals to amend the State Building Code. Unless directed by the State Legislature, federal mandates or court order, the Council will not enter formal rulemaking until 2009 as part of its consideration of adoption of the 2009 series of codes. Proposals to amend the State Building Code shall be made on forms provided by the Building Code Council. Code Change Proposal Submittal Deadline: March 1st of each year. B. Local Amendments: Any jurisdiction may amend the State Building Code provided the amendments do not reduce the minimum performance standards of the codes. There are two areas where local amendments are limited or prohibited.

4 Prohibited Amendments: Residential provisions of the State Energy Code (WAC 51-11), the Ventilation and Indoor Air Quality Code (WAC 51-13); any provision of the International Building Code or International Residential Code affecting accessibility; and standards specifically adopted in Chapters and 19.27A cannot be amended by any local jurisdiction. Residential Amendments: Amendments by local jurisdictions which affect the construction of single family and multi-family residential buildings must be reviewed and approved by the State Building Code Council before such amendments can be enforced. The State Building Code Act provides the following definition: Multi-family residential building: means common wall residential buildings that consist of four or fewer units, that do not exceed two stories in height, that are less than 5,000 square feet in area, and that have a onehour fire-resistive occupancy separation between units.
