EMERGENCY RULES
BUILDING CODE COUNCIL
[Filed March 14, 2014, 5:24 p.m., effective April 1, 2014]
Effective Date of Rule: April 1, 2014.
Purpose: This rule change will resolve conflicts in the Residential Code regarding fire sprinkler requirements for townhouse construction. The current language is unclear and leads to misinterpretation of the code requirements for the building industry and code officials.
Citation of Existing Rules Affected by this Order: Amending WAC 51-51-0302.
Statutory Authority for Adoption: RCW 19.27.031, 19.27.074.
Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest.
Reasons for this Finding: The 2012 Residential Code does not adequately address fire safety requirements for townhouse construction; an error in the current code creates confusion for builders and code officials regarding fire separation and sprinkler requirements. It is not the intent of the code to allow reduced fire protection in nonsprinklered townhouses. This rule clarifies that a two-hour wall is required for fire separation when sprinklers are not present in townhouses.
