Burn Season is now OPEN. A valid APCD Burn Permit is required to burn.
We are highly encouraging those that have held burn permits within the last two years to renew this season online.
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. During Fire Season (approximately May 1 through the declared end of Fire Season) CAL FIRE Permits are also required; contact your local CAL FIRE station for details here.
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.
