This inspection data is intended only as a supplementary format of distributing general information in regards to the sanitation grades of various establishments located within Durham County.  These scores are based upon a ten point scale, such that an establishment receiving a score of at least 90 percent shall be awarded a Grade A, those with scores of at least 80 percent and less than 90 percent shall be awarded a Grade B, and those with scores of at least 70 percent and less than 80 percent shall be awarded a Grade C.  Permits shall be revoked for establishments receiving a score of less than 70 percent.

If an establishment requests a reinspection for the purpose of raising an alphabetical grade, an Environmental Health Specialist shall make an unannounced inspection, after a lapse of reasonable period of time, not to exceed 15 days, from the date of reinspection request.

A sanitation grade card is required to be posted in an area that is conspicuous, where it may be readily observed by the public upon entering the establishment in a location agreeable to management.
