Appliance Standards

Appliance standards represent a cost-effective strategy to protect consumers and businesses and strengthen the state’s clean energy economy. Efficiency products save energy and water, reduce long-term operating costs, and cut greenhouse gas emissions.

On May 7, 2019, Governor Jay Inslee signed into law House Bill 1444, which adds 17 new products (PDF) to state standards last updated in 2009. The standards are estimated to save Washington consumers and businesses $2 billion in energy and water costs.

  • Most standards took effect on January 1, 2021.
  • Effective dates of standards in this legislation are based on date of manufacture, not date of sale.
  • Products already in stores or warehouses may be installed after the new standards take effect.
  • The standards apply to manufacturers, distributors, retailers, and installers, rather than to individual consumers.
