The provisions of the San Diego County Code of Regulatory Ordinances concerning permanent and mobile food facilities, at Title 6, Division 1, of the County Code, are incorporated into this Code by this reference. see full law

Because they are not based on the CRFC, the food facility grading and food handler requirements in this Division (at sections 61.107, 61.108, 61.114 and 61.115) are directly applicable only in the unincorporated portions of San Diego County.  However, parallel provisions have been enacted in all of the incorporated cities in the County.  Because private event catering is not retail food service as defined in the CRFC, requirements applicable to caterers when preparing and serving food at private events (in Chapter 3 of this Division) are based on County general powers in the unincorporated area (California Constitution, article 11, section 7), and on parallel city ordinances and on State-law health officer powers in incorporated cities.  The substantive content of those requirements is based on the CRFC. see full law

(a) The Director may adopt regulations to grade permanent or mobile food facilities that prepare ready-to-eat food, using a letter grade system. The grading system may be used during any inspection the Department conducts. An "A" grade shall represent a score of 90 percent or higher. A "B" grade shall represent a score of 80 to 89 percent. A "C" grade shall represent a score less than 80 percent. The Department shall issue an alphabetical grade card to each food facility graded during an inspection pursuant to this section and shall provide the permit holder with a list of deficiencies found during the grading inspection. If the Department determines from the inspection, however, that the facility presents an imminent health hazard that warrants immediate closure the Department shall not issue the facility a grade card. see full law
