Inspection Score
A composite 0–100 score combining this facility's inspections, citations, complaints, and enforcement actions relative to the New York state average. We don't score profiles with fewer than 3 inspections on record because a small inspection history reads as "below average" on every count-based metric — that would over-reward a facility just for being new.
