A sanitation score below 70 out of 100 is widely considered bad, and in most jurisdictions it means the restaurant has failed its inspection. Scores between 70 and 85 sit in a gray zone: technically passing in some areas but flagged as needing improvement. The exact thresholds vary by city and state, but the general framework is consistent enough to give you a reliable picture of what the numbers mean.
How Sanitation Scores Break Down
Most health departments in the U.S. use a 100-point scale, starting at 100 and subtracting points for each violation an inspector finds. The categories generally look like this:
- 90 to 100: Good. The inspector found only minor, low-risk issues.
- 86 to 90: Adequate. Several violations were observed, but none posed a serious immediate threat.
- 71 to 85: Needs improvement. The restaurant had multiple high-risk violations.
- Below 70: Poor. This is a failing score in most systems.
In cities that use letter grades, like Los Angeles, the scale maps similarly. An A is 90 or above. A B (80 to 89) signals generally good but imperfect food handling. A C (70 to 79) means conditions are only “generally acceptable.” Drop below 70 and the restaurant doesn’t even receive a letter grade in LA County. It gets a numerical score card instead, essentially a public mark of failure.
What Violations Cost the Most Points
Not all violations are equal. Boston’s grading system illustrates the gap well: a foodborne critical violation, like failing to keep food at safe temperatures, costs 10 points. A standard critical violation, such as re-serving unwrapped food, costs 7 points. A non-critical violation, like dirty walls or ceilings, costs just 2 points.
That weighting matters. A restaurant could have several cosmetic issues (dusty vents, scuffed floors) and still score in the 90s. But just a few serious food-handling problems can drag a score into failing territory fast. Three temperature violations alone could knock 30 points off, putting even an otherwise clean restaurant below 70.
The Violations That Cause the Worst Scores
The violations that tank a sanitation score tend to cluster around a few themes. San Francisco’s health department lists the most common ones found during inspections:
- Sick employees handling food while potentially carrying a communicable illness
- Inadequate handwashing by food workers
- Improper holding temperatures, meaning hot food that’s cooled down or cold food that’s warmed up past safe limits
- Misusing time controls for food safety, such as leaving prepared food sitting out too long
- Improper cooling methods, like putting large quantities of hot food directly into a refrigerator without breaking them down first
These all share a common thread: they create conditions where bacteria multiply to dangerous levels. That’s why inspectors weight them so heavily. A cracked floor tile is an eyesore. Chicken sitting at room temperature for three hours is a genuine health risk.
What Happens After a Bad Score
A restaurant that scores below 70 on an inspection has failed to meet the minimum acceptable sanitation standard. What follows depends on the jurisdiction, but the general process is predictable. The inspector documents every violation and sets a timeframe for corrections. Some violations, particularly anything classified as an imminent danger to public health (spoiled food, contaminated ingredients, temperature abuse), must be corrected on the spot before the inspector leaves.
Oregon’s enforcement protocol spells out four situations that can trigger an immediate closure: an uncorrected violation that presents an imminent hazard, a score below 70 after the restaurant has already failed to comply with previous corrections, failure to implement required alternative procedures, or failure to fix serious violations within the deadline. Operating a restaurant that’s been closed for these reasons can result in civil penalties.
Even when a restaurant isn’t shut down immediately, a failing score typically triggers a reinspection. The local health department sets the timeline, which can range from days to a few weeks depending on how severe the violations are. The restaurant needs to demonstrate that it’s fixed the problems before that follow-up visit.
How to Check a Restaurant’s Score
Most jurisdictions require restaurants to make their inspection results visible to the public, though the format varies. Some cities, like New York and Los Angeles, mandate that a letter grade card be posted in a conspicuous spot near the entrance, placed there by the inspector. North Carolina state law requires every inspected establishment to display a grade card showing both the letter grade and numerical score in the same size type, side by side.
Other places take a lighter approach. California law requires restaurants to post a sign stating that health inspection information is available upon request. Some jurisdictions simply require the full inspection report to be posted inside the restaurant where customers can see it. And nearly every major city now publishes inspection results in a searchable online database, so you can look up any restaurant before you visit.
The labeling systems themselves differ from place to place. You might see letter grades, numerical scores, or qualitative ratings like “Satisfactory,” “Conditionally Satisfactory,” and “Unsatisfactory,” or “Meets Minimum Standards” versus “Does Not Meet Minimum Standards.” Regardless of the format, the underlying inspection covers the same core food safety principles.
How Much a Score Should Worry You
A score in the low 90s with a couple of minor deductions is normal and not a reason to avoid a restaurant. Inspections are snapshots, and small issues like a slightly disorganized storage area or a missing label on a container are common even in well-run kitchens. A score in the 80s suggests the restaurant has some real but manageable food safety gaps.
Once you’re looking at scores in the 70s or below, the math tells you something specific: the restaurant accumulated enough high-risk violations that inspectors found multiple serious problems in a single visit. That’s a pattern worth paying attention to, especially if the restaurant has scored poorly on more than one inspection. A single bad score followed by a clean reinspection tells a different story than repeated failures in the 60s or 70s. Most online databases show the full inspection history, so you can check whether a low score was a one-time slip or an ongoing issue.
