Summary

St. Charles County food establishments must display notice stickers at every public entrance and drive-up or walk-up window telling customers the site is subject to Department of Public Health inspection, and inspectors score each visit out of 100 points. Operating without a permit draws a $500-per-day fine, and repeat violators face mandatory closure.

These county ordinances apply to unincorporated areas of St. Charles County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

41. Section 8-403.11 shall be added and read as follows: Scoring of Inspection. (A) In accordance with Section 8-405.11, each PRIORITY ITEM OR PRIORITY FOUNDATION ITEM marked in violation on the inspection form shall be assigned a five (5) point demerit score. (B) In accordance with Section 8-406.11, each CORE ITEM marked in violation on the inspection form shall be assigned a two (2) point demerit score. (C) All demerit scores of PRIORITY ITEMS or PRIORITY FOUNDATION ITEMS and CORE ITEMS shall be totaled and subtracted from one hundred (100) possible points to determine the overall score of the food establishment. 42. Section 8-403.12 shall be added and read as follows: Notice to Public of Inspections. (A) Every food establishment shall display, without obstruction in a conspicuous place designated by the Department, notice stickers that inform the public that the establishment is subject to inspection by the Department. Such notice stickers shall be displayed at every public entrance and at every drive-up and/or walk-up window of every food establishment.

Frequently Asked Questions

Does St. Charles County post letter grades like A or B on restaurants?
No. County Code § 230.010 requires notice stickers at every entrance and drive-up window telling customers the establishment is inspected, plus posting of the first page of the most recent inspection form showing its numeric score out of 100, rather than a letter grade.
How often does the county inspect restaurants?
Section 8-401.10 sets a baseline of at least once every 18 months, though the Department of Public Health can increase the frequency for an individual establishment if warranted.
What happens if a restaurant operates without a permit?
County Code § 230.020 makes it a $500-per-day fine for each day of unpermitted operation, and the Department can order the establishment closed immediately in addition to that penalty.
Can a restaurant appeal a suspended permit?
Yes. The permit holder can request a hearing under Section 8-304.23, and can further appeal the enforcement officer's decision to the Department Director within five working days; the Director's ruling is final.
