NEW THIS YEAR: In addition to an APCD Agricultural Burn Permit, in most areas of the county a CAL FIRE permit is also required for agricultural burning. To obtain a CAL FIRE permit, go to https://burnpermit.fire.ca.gov/ 

We highly encourage those that have held burn permits within the last two years to renew online this season.

Agricultural Burn Permit Overview

  • Agricultural burning is defined as open outdoor fires used in agricultural operations in the growing of crops or raising of fowl or animals, used in vegetation, forest or range management, the improvement of land for wildlife and game habitat, or agricultural disease or pest prevention.
  • In order to qualify for an Agricultural burn permit, the applicant must be able to prove that income is derived from agricultural practices on property where the burn is located; a Farmers' Market Certificate is sufficient proof of agricultural income.
  • Agricultural burning is allowed year-round on Permissive Burn Days in San Luis Obispo County by permit. 
  • A separate permit is required for each non-contiguous or non-adjacent property.
  • Any burning of cannabis waste is prohibited.
  • The fee for an agricultural burn permit is $100.
