Much of the paint we receive at our facilities is still useful—sometimes even still brand new—and it's available at no cost to Salt Lake County residents (no businesses, please) at either of our two Reuse Sheds:

Salt Lake Valley Landfill
Household Hazardous Waste Reuse Shed
6030 West California Avenue (1300 South)
Salt Lake City, UT 84104
801-541-4078  
Open Monday through Saturday, 7:00 am to 5:00 pm

Trans-Jordan Landfill
Household Hazardous Waste Reuse Shed

South Jordan, UT 84009     
801-971-1976

Please call ahead to inquire if any paint is available, and please take only what you need. The Salt Lake Valley Habitat for Humanity ReStore often has highly discounted paint, as well.
