San Luis Obispo County, CA Trash & Recycling: Illegal Dumping (2026)

920(a) prohibits placing or dumping, or hiring anyone to place or dump, solid waste or recyclables on the right-of-way of any public highway, street or thoroughfare, on the banks of any stream or dry watercourse, or on private property, occupied or not, anywhere in the county. 610. 5 and Title 22 of the California Code of Regulations instead. 12 violations. 930 lets the health officer order it removed: the owner or occupant gets a certified-mail notice to remove the waste, and if it is not gone within five days of receipt (seven if the notice comes back undelivered), the health officer can clean the site directly or pay someone else to do it.

The county then itemizes its cleanup costs, notices the property owner of a hearing before the board of supervisors at least fifteen days out, and, once the board confirms the account, records a lien against the parcel that collects alongside county property taxes. 940 lets the county use that same removal-and-lien process against any noncompliant dump site or solid waste facility, tying the illegal-dumping ban directly to the county's cost-recovery power.
