19.27.020
Purposes—Objectives—Standards.

The purpose of this chapter is to promote the health, safety and welfare of the occupants or users of buildings and structures and the general public by the provision of building codes throughout the state. Accordingly, this chapter is designed to effectuate the following purposes, objectives, and standards:
(1) To require minimum performance standards and requirements for construction and construction materials, consistent with accepted standards of engineering, fire and life safety.
(2) To require standards and requirements in terms of performance and nationally accepted standards.
(3) To permit the use of modern technical methods, devices and improvements.
(4) To eliminate restrictive, obsolete, conflicting, duplicating and unnecessary regulations and requirements which could unnecessarily increase construction costs or retard the use of new materials and methods of installation or provide unwarranted preferential treatment to types or classes of materials or products or methods of construction.
(5) To provide for standards and specifications for making buildings and facilities accessible to and usable by physically disabled persons.
(6) To consolidate within each authorized enforcement jurisdiction, the administration and enforcement of building codes.



19.27.031
State building code—Adoption—Conflicts—Opinions.

Except as otherwise provided in this chapter, there shall be in effect in all counties and cities the state building code which shall consist of the following codes which are hereby adopted by reference:
(1)(a) The International Building Code, published by the International Code Council, Inc.;
(b) The International Residential Code, published by the International Code Council, Inc.;
(2) The International Mechanical Code, published by the International Code Council, Inc., except that the standards for liquefied petroleum gas installations shall be NFPA 58 (Storage and Handling of Liquefied Petroleum Gases) and ANSI Z223.1/NFPA 54 (National Fuel Gas Code);
(3) The International Fire Code, published by the International Code Council, Inc., including those standards of the National Fire Protection Association specifically referenced in the International Fire Code: PROVIDED, That, notwithstanding any wording in this code, participants in religious ceremonies shall not be precluded from carrying handheld candles;
(4) Except as provided in RCW 19.27.170, the Uniform Plumbing Code and Uniform Plumbing Code Standards, published by the International Association of Plumbing and Mechanical Officials: PROVIDED, That any provisions of such code affecting sewers or fuel gas piping are not adopted;
(5) The rules adopted by the council establishing standards for making buildings and facilities accessible to and usable by individuals with disabilities or elderly persons as provided in RCW 70.92.100 through 70.92.160; and
(6) The state's climate zones for building purposes are designated in RCW 19.27A.020(3) and may not be changed through the adoption of a model code or rule.
In case of conflict among the codes enumerated in subsections (1), (2), (3), and (4) of this section, the first named code shall govern over those following.
The codes enumerated in this section shall be adopted by the council as provided in RCW 19.27.074. The council shall solicit input from first responders to ensure that firefighter safety issues are addressed during the code adoption process.
The council may issue opinions relating to the codes at the request of a local official charged with the duty to enforce the enumerated codes.
NOTES:
FindingIntent2015 c 11: "The legislature finds that the state building code council adopted by rule changes to the climate zones used in the building codes due to modifications in the 2012 international energy conservation code (IECC). The legislature intends to update the statutes to be more reflective of the national standards." [ 2015 c 11 § 1.]
IntentFinding2003 c 291: "(1) The intent of the adoption of the International Building Code by the legislature is to remain consistent with state laws regulating construction, including electrical, plumbing, and energy codes established in chapters 19.27, 19.27A, and 19.28 RCW. The International Building Code references the International Residential Code for provisions related to the construction of single and multiple-family dwellings. No portion of the International Residential Code shall supersede or take precedent over provisions in chapter 19.28 RCW, regulating the electrical code; nor provisions in RCW 19.27.031(4), regulating the plumbing code; nor provisions in chapter 19.27A RCW, regulating the energy code.
(2) It is in the state's interest and consistent with the state building code act to have in effect provisions regulating the construction of single and multiple-family residences. It is the legislative intent that the state building code council adopt the International Residential Code through rule making granted in RCW 19.27.074, consistent with state law regulating construction for electrical, plumbing, and energy codes, and other state and federal laws regulating single and multiple-family construction.
(3) In accordance with RCW 19.27.020, the state building code council shall promote fire and life safety in buildings consistent with accepted standards. In adopting the codes for the state of Washington, the state building code council shall consider provisions related to firefighter safety published by nationally recognized organizations. The state building code council shall review all nationally recognized codes as set forth in RCW 19.27.074.
(4) The legislature finds that building codes are an integral component of affordable housing. In accordance with this finding, the state building code council shall consider and review building code provisions related to improving affordable housing." [ 2003 c 291 § 1.]
Severability1989 c 348: See note following RCW 90.54.020.
Rights not impaired1989 c 348: See RCW 90.54.920.



19.27.035
Process for review.

The building code council shall, within one year of July 23, 1989, adopt a process for the review of proposed statewide amendments to the codes enumerated in RCW 19.27.031, and proposed or enacted local amendments to the codes enumerated in RCW 19.27.031 as amended and adopted by the state building code council.



19.27.040
Cities and counties authorized to amend state building code—Limitations.

The governing body of each county or city is authorized to amend the state building code as it applies within the jurisdiction of the county or city.

Building permit application—Evidence of adequate water supply—Applicability—Exemption.

(1) Each applicant for a building permit of a building necessitating potable water shall provide evidence of an adequate water supply for the intended use of the building. Evidence may be in the form of a water right permit from the department of ecology, a letter from an approved water purveyor stating the ability to provide water, or another form sufficient to verify the existence of an adequate water supply. In addition to other authorities, the county or city may impose conditions on building permits requiring connection to an existing public water system where the existing system is willing and able to provide safe and reliable potable water to the applicant with reasonable economy and efficiency. An application for a water right shall not be sufficient proof of an adequate water supply.
(2) Within counties not required or not choosing to plan pursuant to RCW 36.70A.040, the county and the state may mutually determine those areas in the county in which the requirements of subsection (1) of this section shall not apply.

Recycled materials—Study code and adopt changes.

The state building code council, in consultation with the department of ecology and local governments, shall conduct a study of the state building code, and adopt changes as necessary to encourage greater use of recycled building materials from construction and building demolition debris, mixed waste paper, waste paint, waste plastics, and other waste materials.



19.27.180
Residential buildings moved into a city or county—Applicability of building codes and electrical installation requirements.

(1) Residential buildings or structures moved into or within a county or city are not required to comply with all of the requirements of the codes enumerated in chapters 19.27 and 19.27A RCW, as amended and maintained by the state building code council and chapter 19.28 RCW, if the original occupancy classification of the building or structure is not changed as a result of the move.
(2) This section shall not apply to residential structures or buildings that are substantially remodeled or rehabilitated, nor to any work performed on a new or existing foundation.
(3) For the purposes of determining whether a moved building or structure has been substantially remodeled or rebuilt, any cost relating to preparation, construction, or renovation of the foundation shall not be considered.
NOTES:
Finding1989 c 313: "The legislature finds that moved buildings or structures can provide affordable housing for many persons of lower income; that many of the moved structures or buildings were legally built to the construction standards of their day; and that requiring the moved building or structure to meet all new construction codes may limit their use as an affordable housing option for persons of lower income.
The legislature further finds that application of the new construction code standards to moved structures and buildings present unique difficulties and that it is the intent of the legislature that any moved structure or building that meets the codes at the time it was constructed does not need to comply with any updated state building code unless the structure is substantially remodeled or rebuilt." [ 1989 c 313 § 1.]



19.27.190
Indoor air quality—Interim and final requirements for maintenance.

(1)(a) Not later than January 1, 1991, the state building code council, in consultation with the *department of community, trade, and economic development, shall establish interim requirements for the maintenance of indoor air quality in newly constructed residential buildings. In establishing the interim requirements, the council shall take into consideration differences in heating fuels and heating system types. These requirements shall be in effect July 1, 1991, through June 30, 1993.
(b) The interim requirements for new electrically space heated residential buildings shall include ventilation standards which provide for mechanical ventilation in areas of the residence where water vapor or cooking odors are produced. The ventilation shall be exhausted to the outside of the structure. The ventilation standards shall further provide for the capacity to supply outside air to each bedroom and the main living area through dedicated supply air inlet locations in walls, or in an equivalent manner. At least one exhaust fan in the home shall be controlled by a dehumidistat or clock timer to ensure that sufficient whole house ventilation is regularly provided as needed.
(c)(i) For new single-family residences with electric space heating systems, zero lot line homes, each unit in a duplex, and each attached housing unit in a planned unit development, the ventilation standards shall include fifty cubic feet per minute of effective installed ventilation capacity in each bathroom and one hundred cubic feet per minute of effective installed ventilation capacity in each kitchen.
(ii) For other new residential units with electric space heating systems the ventilation standards may be satisfied by the installation of two exhaust fans with a combined effective installed ventilation capacity of two hundred cubic feet per minute.
(iii) Effective installed ventilation capacity means the capability to deliver the specified ventilation rates for the actual design of the ventilation system. Natural ventilation and infiltration shall not be considered acceptable substitutes for mechanical ventilation.
(d) For new residential buildings that are space heated with other than electric space heating systems, the interim standards shall be designed to result in indoor air quality equivalent to that achieved with the interim ventilation standards for electric space heated homes.
(e) The interim requirements for all newly constructed residential buildings shall include standards for indoor air quality pollutant source control, including the following requirements: All structural panel components of the residence shall comply with appropriate standards for the emission of formaldehyde; the back-drafting of combustion by-products from combustion appliances shall be minimized through the use of dampers, vents, outside combustion air sources, or other appropriate technologies; and, in areas of the state where monitored data indicate action is necessary to inhibit indoor radon gas concentrations from exceeding appropriate health standards, entry of radon gas into homes shall be minimized through appropriate foundation construction measures.
(2) No later than January 1, 1993, the state building code council, in consultation with the *department of community, trade, and economic development, shall establish final requirements for the maintenance of indoor air quality in newly constructed residences to be in effect beginning July 1, 1993. For new electrically space heated residential buildings, these requirements shall maintain indoor air quality equivalent to that provided by the mechanical ventilation and indoor air pollutant source control requirements included in the February 7, 1989, Bonneville power administration record of decision for the environmental impact statement on new energy efficient homes programs (DOE/EIS-0127F) built with electric space heating. In residential units other than single-family, zero lot line, duplexes, and attached housing units in planned unit developments, ventilation requirements may be satisfied by the installation of two exhaust fans with a combined effective installed ventilation capacity of two hundred cubic feet per minute. For new residential buildings that are space heated with other than electric space heating systems, the standards shall be designed to result in indoor air quality equivalent to that achieved with the ventilation and source control standards for electric space heated homes. In establishing the final requirements, the council shall take into consideration differences in heating fuels and heating system types.

(2)(a) The building code council may phase in the carbon monoxide alarm requirements on a schedule that it determines reasonable, provided that the rules require that by January 1, 2011, all newly constructed buildings classified as residential occupancies will be equipped with carbon monoxide alarms, and all other buildings classified as residential occupancies will be equipped with carbon monoxide alarms by January 1, 2013.
(b) Owner-occupied single-family residences legally occupied before July 26, 2009, are exempt from the requirements of this subsection (2). However, for any owner-occupied single-family residence that is sold on or after July 26, 2009, the seller must equip the residence with carbon monoxide alarms in accordance with the requirements of the state building code before the buyer or any other person may legally occupy the residence following such sale.
(3) The building code council may exempt categories of buildings classified as residential occupancies if it determines that requiring carbon monoxide alarms are unnecessary to protect the health and welfare of the occupants.
(4) The rules adopted by the building code council under this section must (a) consider applicable nationally accepted standards and (b) require that the maintenance of a carbon monoxide alarm in a building where a tenancy exists, including the replacement of batteries, is the responsibility of the tenant, who shall maintain the alarm as specified by the manufacturer.
(5) Real estate brokers licensed under chapter 18.85 RCW shall not be liable in any civil, administrative, or other proceeding for the failure of any seller or other property owner to comply with the requirements of this section or rules adopted by the building code council.
NOTES:
Findings2012 c 132: See note following RCW 64.06.020.
Intent2009 c 313: "The legislature recognizes that carbon monoxide poses a serious threat. According to national statistics from the centers for disease control, carbon monoxide kills more than five hundred people and accounts for an estimated twenty thousand emergency department visits annually. Specifically, Washington state has experienced the dire effects of carbon monoxide poisoning. In the storms that struck Washington in December 2006, it was estimated that over one thousand people in the state were seen at hospital emergency rooms with symptoms of carbon monoxide poisoning, and eight people reportedly died of carbon monoxide exposure. It is the intent of the legislature to implement policies to prevent similar tragedies from occurring in the future." [ 2009 c 313 § 1.]
