Source: Los Angeles County DPH, NYC DOHMH, Florida DBPR, Chicago DPH public restaurant inspection records, 2023–2026. Routine inspections only.
Tool: Python (pandas, matplotlib).
Definitions
* **Chain** = brand name appears at ≥10 distinct facilities in that city’s dataset
* **Independent** = brand name appears at exactly 1 facility in that city
* Brands with 2–9 locations excluded as ambiguous (small regional chains, growing single-owner concepts, franchise carve-outs)
Method: within each city, share of routine inspections scoring at or above that city’s own median routine score. The „city’s own median“ framing avoids cross-city scoring-system bias. LA uses 0–100 with deductions, NYC uses violation-points-normalized, Florida uses the DBPR scale, Chicago uses a numerical scale derived from violation severity. The four scales aren’t directly comparable, but each city’s bars are computed against its own internal benchmark.
Sample: 21,258 chain facilities, 95,947 single-location indie facilities, ~260,000 routine inspections.
Caveats
* Survivor bias may amplify the gap: failed indies have more likely closed and dropped out of the 2023–2026 window than failed chains (which usually get a corporate save).
* Brand-name matching is fuzzy („STARBUCKS COFFEE“ and „STARBUCKS“ both collapse to one brand), but this is symmetric and shouldn’t bias the comparison.
* Excludes food trucks, caterers, and event vendors that are absent from inspection rolls.
This should surprise no one who has ever dealt with a „small business“
This makes sense to me. I assume that chain restaurants have their own internal audit process and corporate requires the violators get into compliance or get kicked out.
Sometimes Corporate One-Size-Fits-All works better than „We’ll make it work“.
Big chains have more to lose if someone reports food illness. Chipotle lost hundreds of millions for the E coli outbreak in 2015
I learned this by the amount of restaurants on Kitchen Nightmares.
I often find myself arguing to support this data.
Your graph will definitely come in handy the next time I get a chance.
Thanks
Standardized procedures, training, machinery, parts along with corporate emphasis on efficiency, loss production, and stream of service gets you 80% there to running a clean boh
If all the food is pre-made and frozen and employees just have to pop it in the microwave, it probably is more sanitary at that point than a mom-and-pop shop that makes everything in-house. I wonder if the mom-and-pop shops don’t end up being healthier in the long run, though, because half their menu isn’t ultra-processed pre-packaged garbage.
Anecdotally I work at a Chick-fil-A and the health inspector making a surprise visit is pretty much met with a collective shrug.
Our internal surprise inspections are waaaaay more strict.
cleaner doesn’t mean better food though. some of the best meals i’ve had were at places i probably shouldn’t think too hard about
It makes sense, right?
Chains have standards, the have policies and procedures, and generally have a *few* more requirements when going through the hiring process.
Independent places probably have some of the BEST examples of cleanliness out there, but also encompass almost all the worst ones too.
