Existing law, the California Retail Food Code, establishes uniform health and sanitation standards for retail food facilities, which are primarily enforced by local public health agencies. Violation of the California Retail Food Code is a misdemeanor, except as otherwise provided. Existing law limits the size of a passthrough window service opening to 216 square inches, and requires the opening to be provided with a solid or screened window, equipped with a self-closing device. Existing law authorizes a passthrough window of up to 432 square inches if equipped with an air curtain device. This bill would remove the requirement that the 216 square inch solid or screened window has to be equipped with a self-closing device. The bill would require a passthrough window service opening of up to 432 square inches to be equipped with an air curtain device or a self-closing device. The bill would require a passthrough window service opening that is larger than 432 square inches to be equipped with both a self-closing device and an air curtain device. The bill would require a passthrough window or other service opening to be used specifically for food delivery operations and not as a general entrance or exit for employees or customers. By expanding the scope of an existing crime, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
