To confirm the decline was real and not the result of an incomplete download, I compared two separate extracts of the same County dataset. The analysis uses the first extract, downloaded in February 2026, covering January 2023 through September 2025. The second extract runs through March 2026, so it was necessarily pulled later. Over the period they share, April 2023 through September 2025, the two are identical: the same 36,835 routine inspections, agreeing in every one of the 30 months, down to the same individual records. Because the later extract was pulled roughly six months after the analysis window closed, any inspections still being entered for the declining period had time to appear in it. None did. The decline is in the data, not in the timing of the download.
One limit is worth stating directly. The second extract begins in April 2023, so the first quarter of 2023, about 11,250 inspections and 42 percent of the baseline, exists only in the first extract and could not be cross-checked. This does not change the result. The full decline period was reproduced exactly, and on the months both extracts completely share, the decline measures 81.6 percent, essentially the headline figure.
Of 37,026 violations, 36,062 are classified by severity:
964 additional records (2.6% of all 37,026 violations) are logged as out of compliance, a correction status rather than a severity level, and are not included in the chart above.
Inspections by the LA County Department of Public Health's District Inspection Branch (DIB) dropped 82% over the same nine months of 2023 and 2025 while violations per inspection rose. The data does not explain why.
Even as DIB inspection volume collapsed, three laws expanded what the same division is legally required to enforce.
RHHP applies only to unincorporated areas, which were under 1% of the inspections analyzed here, so this decline is not explained by inspections shifting into RHHP.
DIB's own inspection guide describes annual routine inspection of five-or-more-unit buildings as program practice. No statute, ordinance, or contract requires any inspection frequency for incorporated cities, which is why practice could fall 82% with no rule broken.
The decline did not slow what DIB is legally required to enforce. Three laws expanded the mandate while inspection volume fell 82%.
