Seattle King County WDC Mandate: Why Seattle-King County Plans on Mandating the WDC For Multifamily Buildings

May 28, 2024 • IAPMO • Season 4 • Episode 8

On this week’s episode, we’re going to be talking about how Seattle improved water savings and reduced new construction costs through accurate pipe sizing. Seattle recently mandated the use of the IAPMO Water Demand Calculator® for multifamily residences, also known as R2 occupancies. The inclusion of Appendix M in the city’s plumbing codes puts Seattle on the cutting edge of sustainability and resiliency by creating a pathway for significant reductions in potable water use, improving energy, as well as significant reductions in new construction costs. Joining me for this episode is Steven Hart, chief of the Plumbing and Gas Piping Program in Public Health for Seattle & King County, and Duane Jonlin, FAIA, Energy Code and Energy Conservation advisor for the City of Seattle Department of Construction and Inspections.
