What to do with tires, mattresses, paint, and more

Before you go

  • Show your driver’s license as proof of Howard County residence each time; staff may check the address. Nothing from outside the county is accepted.
  • Residents may bring up to 2 tons of household trash and 2 tons of yard trim free each year from July through June, in a vehicle up to 3/4 ton registered in the county. Past that, it’s weighed and charged the commercial rate.
  • A dump truck, box truck, trailer, or rental vehicle counts as commercial: it crosses the scales, and fees may apply. Trailers, box trucks, and rental trucks can’t enter the Residents’ Convenience Center.
