Energy: appliance standards and cost-effective measures

California appliance-efficiency rules now cover rentals, imports, distribution, and leases—not only sales.

The law closes transaction-based gaps in enforcement of California’s energy- and water-efficiency appliance standards. Manufacturers must certify covered new appliances comply before they enter the California end-use market through any covered channel.

What the law does

  • Prohibits covered new appliances made after an applicable standard or cost-effective measure takes effect from being sold, rented, imported, distributed, or leased in California without manufacturer certification of compliance.
  • Extends the prohibition to offers to sell, rent, import, distribute, or lease covered appliances.
  • Applies the rules to transactions for end use in California regardless of where the seller, renter, importer, distributor, or lessor is located, including internet, telephone, and mail-order transactions.
  • Requires the manufacturing date to be permanently displayed in an accessible place on regulated new appliances, except plumbing fittings.

Who it affects

  • Appliance manufacturers.
  • Appliance sellers, rental businesses, importers, distributors, and lessors serving California end users.
  • California consumers and businesses obtaining covered new appliances.
