How to pass a restaurant health inspection in the US: grades, violations, preparation

The knock comes on a Tuesday at 11:40 am, mid-prep, with a full book for lunch. Health inspections in the US are unannounced by design: in New York City, for example, every restaurant is scheduled for an unannounced inspection at least once a year. You cannot schedule the inspection, but you can absolutely decide what the inspector finds. Restaurants that pass with strong scores are not lucky, they run the same routine every single day.

This guide explains how the US inspection system actually works (it is local, not federal), how the famous letter grades are calculated in New York City and Los Angeles County, which violations inspectors cite most often based on published city data, and what to do before, during and after the visit.

One organizational note before the kitchen talk: an inspection always lands at a bad moment, and the manager who spends the visit walking the inspector through the walk-in cannot also be untangling the reservation book. Front-of-house systems that run themselves, like an online reservation system that is free and takes no commission, confirm bookings automatically while you deal with what only you can handle. If you are still at the permit stage, our guide to opening a restaurant in the US covers the pre-operational inspection that comes before this one.

How health inspections actually work in the US

There is no federal restaurant inspector. Retail food safety is enforced by state, county and city health departments: depending on your address, the badge at your door belongs to a county environmental health division (most of the country), a city health department (New York City), or a state agency.

What keeps this patchwork roughly coherent is the FDA Food Code, a model code that the FDA publishes and updates periodically (the current edition is the 2022 Food Code). It is not federal law: each state or locality adopts its own version, sometimes the latest edition, sometimes an older one with local amendments. That is why the fundamentals (cold holding, hot holding, handwashing, cross-contamination, pest control) are similar everywhere, while the details (exact temperatures, certification rules, grading) vary from one county to the next.

Practical consequence: your real rulebook is your local health code, not a national blog post, including this one. Your health department's website publishes the inspection form, the scoring rules and usually a self-inspection checklist. Read the actual form your inspector will fill in; it removes all the mystery.

Who inspects you, and how often

Inspection frequency is typically risk-based: full-service restaurants that cook raw proteins get inspected more often than a coffee counter. Poor performance also raises the frequency. In New York City, a restaurant that scores 0-13 points on its initial inspection is next inspected in 11 to 13 months, while higher-scoring restaurants cycle back in as little as 3 to 5 months. Doing well literally buys you time.

Letter grades: how New York City and Los Angeles County score restaurants

Most of the country uses inspection reports without public grades, but the two most famous grading systems in the US work in opposite directions, and both hang the result in your window.

In New York City, restaurants have been required to post letter grades since 2010: 0 to 13 points is an A, 14 to 27 is a B, 28 or more is a C, and each sanitary violation found during the inspection adds points. The city also notes that restaurants are not fined for sanitary violations found during an inspection that results in an A grade: a clean kitchen protects your cash, not just your reputation.

In Los Angeles County, each inspection starts at 100 points and violations subtract from it: 90-100 is an A, 80-89 a B, 70-79 a C. Below 70, the restaurant must post its raw numeric score, and a facility that scores below 70 twice within twelve months is subject to closure. A critical violation can close a facility regardless of the score. The grading ordinance applies in unincorporated areas and in the many cities that adopted it, including the City of Los Angeles (since 1998).

Wherever grades exist, they are marketing whether you like it or not: guests see the card before they see the menu, and a grade drop shows up in your Google reviews faster than in your revenue reports.

The violations inspectors cite most often (real data)

You do not have to guess what inspectors look for. New York City publishes every inspection result as open data, and the pattern is remarkably stable. Computed from the DOHMH Restaurant Inspection Results dataset (covering roughly the last three years of citywide inspections, retrieved on August 14, 2026), the most frequently cited violations are:

1. Non-food-contact surfaces not kept clean or not built to be cleanable (shelving, equipment exteriors, gaskets): about 40,000 citations, the single most common violation by a wide margin.
2. Conditions conducive to pests: harborage, gaps, clutter, even without a single mouse in sight (about 25,000 citations).
3. Food-contact surfaces not washed, rinsed and sanitized after each use (about 19,000).
4. Cold food held above 41 °F (about 19,000): the classic overloaded lowboy or an under-performing walk-in.
5. Plumbing problems: missing backflow prevention, poor drainage, condensation dripping where it should not (about 19,000).
6. Food not protected from contamination during storage, prep or display (about 17,000): raw chicken above ready-to-eat food is the textbook case.
7. Hot food held below 140 °F (about 15,000).
8. Evidence of mice (about 14,000) and flies (about 10,000).
9. No certified food protection supervisor present (about 8,000 citations for a missing Food Protection Certificate).

Read that list again: almost none of it is exotic. It is cleaning schedules, thermometers, storage order and pest proofing. That is genuinely good news, because every item on it is preventable with routine, not capital expenditure.

Before the inspection: a preparation routine that holds up

The restaurants that pass are the ones that would pass on any random day. Four habits cover the bulk of the list above.

Keep temperature logs, and actually use a thermometer

Cold holding at or below 41 °F and hot holding at your local threshold (140 °F in New York City; the 2022 FDA Food Code model uses 135 °F, so check your code) are the highest-point-value items on most inspection forms. The fix costs a few dollars: a calibrated probe thermometer per station and a written log (paper or app) at set times, for example at opening, before service and at close. Logs do double duty: they catch a dying compressor before it costs you a walk-in full of product, and they show the inspector a functioning food safety culture, not a one-day cleanup. Date labels and first-in-first-out rotation belong to the same habit, and they cut spoilage costs at the same time as they satisfy the inspector.

Get your manager certification in order

The FDA Food Code model expects food establishments to have a Certified Food Protection Manager (CFPM), someone who passed an accredited exam (ServSafe is the best-known), and most jurisdictions have made a version of that requirement law. New York City requires a supervisor with a Food Protection Certificate on site, and as the data above shows, thousands of restaurants get cited every cycle for not having one, which is among the cheapest violations to prevent. Train beyond the one certificate holder: the inspector will watch how the whole line handles gloves, handwashing and allergens. Allergen handling has its own legal layer, covered in our guide to US restaurant allergen rules.

Treat pest control as a contract, not a reaction

Pest violations are really two different lines on the form: actual evidence (droppings, flies) and conditions conducive to pests (gaps under doors, holes around pipes, cardboard stacked in a damp corner). You can be cited for the second with zero live animals on site. A monthly contract with a licensed pest management professional, a logbook of their visits, and a walk-through for entry points every quarter address both. Inspectors consistently treat a documented pest program as a strong good-faith signal.

Run your own inspection monthly

Download your jurisdiction's actual inspection form and have a manager fill it in, honestly, once a month, ideally walking the same route an inspector does: outside in, delivery door to dining room. Score it. Fix what you find, and keep the completed sheets: they are useful evidence of diligence if you ever contest a citation.

During the inspection: your rights and the right reflexes

• Verify identity. Real inspectors carry official identification and expect to show it; New York City even publishes a guide on how to identify a health inspector. Scammers posing as inspectors and demanding on-the-spot payment are a known problem: health departments do not collect cash in your kitchen.
• Accompany the inspector. You (or your most senior manager present) should walk with them the entire time: you will hear observations as they are made, can answer questions accurately, and will understand every line of the report instead of discovering it later.
• Correct on the spot when you can. If the sanitizer bucket is at the wrong concentration or a product is mislabeled, fix it immediately, visibly. Depending on the jurisdiction the points may still be recorded, but on-the-spot correction is noted in the report and shows exactly the attitude enforcement discretion rewards.
• Stay professional, never obstructive. Arguing, refusing access or anything that could look like an inducement will convert a fixable inspection into a serious problem. Ask questions instead: inspectors are generally willing to explain what code section applies and what compliance looks like.
• Get the report before they leave, and make sure you understand which violations are critical, what must be fixed by when, and whether a reinspection is coming.

After the inspection: reinspection, appeals and closures

Reinspection. In graded jurisdictions a mediocre first result is usually not final. In New York City, a restaurant scoring 14 or more points on its initial inspection is not graded on the spot: it gets a reinspection at least 7 days later, and the grade comes from that second visit. Those days are your window to fix everything cited, not just the critical items.

Contesting the result. In New York City, a restaurant graded B or C at reinspection may post a "Grade Pending" card instead while it contests the result at the Office of Administrative Trials and Hearings (OATH). Elsewhere, health departments have administrative appeal or office-conference procedures; the deadlines are short, so read the report's appeal instructions the same day.

Closure. Health departments can order an immediate closure for a public health hazard that cannot be corrected on the spot (sewage backup, no hot water, gross pest infestation) or for operating without a valid permit; New York City states this explicitly in its inspection cycle documentation, and Los Angeles County closes facilities that score below 70 twice in twelve months. A closure notice posted on your door is the worst possible advertising, but the process to reopen is standard: correct the hazards, request the reinspection, and reopen only when the department authorizes it.

Afterwards, close the loop. Fix root causes rather than symptoms (a failing gasket, not just the temperature it caused), brief the whole team on what was cited, and fold the findings into the monthly self-inspection. In Los Angeles County you must also keep the most recent inspection report available for any customer who asks.

Frequently asked questions

How often do restaurant health inspections happen?

It depends on your jurisdiction and your track record. New York City inspects every restaurant at least once a year, and more often after poor scores: a restaurant scoring 28+ points sees the next cycle begin in as little as 3 to 5 months, versus 11 to 13 months after a clean A. Most counties use similar risk-based schedules.

Are health inspections ever announced in advance?

Routine inspections are unannounced; that is the point of them. Some departments offer separate announced visits, like New York City's consultative inspections for new establishments, which are educational and not graded. Plan for the inspector to arrive on your worst day, because eventually they will.

What score do I need for an A grade?

In New York City, 0 to 13 violation points on a graded inspection. In Los Angeles County, 90 to 100 points remaining out of 100. Both cities require the resulting card to be posted where the public can see it.

Can I appeal my grade or my violations?

Usually yes. New York City restaurants can contest violations at an OATH hearing and post a "Grade Pending" card in the meantime. Other jurisdictions have their own administrative review procedures with short deadlines listed on the inspection report itself.

What are the most common violations to check first?

Based on New York City's published inspection data: dirty or non-cleanable surfaces, conditions that attract pests, inadequate washing and sanitizing of food-contact surfaces, cold food above 41 °F, hot food below the required holding temperature, and missing food protection certification. A monthly self-inspection against your local form catches nearly all of them.

Does a health inspector have the right to enter my restaurant?

Holding a food service permit generally carries the obligation to allow inspections during operating hours, and refusing entry typically triggers enforcement against the permit itself. Verify the inspector's official identification, then cooperate and accompany them throughout the visit.
