Methodology
How the ContractorCheck Score works.
We synthesize three city datasets — business licenses, building permits, building violations — into a single 0–100 score. Here's every variable, its weight, and how we display it.

Scale fit10%100
A perfect 100 requires: active license, consistent 24-month permit activity, zero compliance issues, 10+ years in business, and permit values matching a typical home-services project.
Modifiers can push scores outside these bounds: +5 for zero violations in 36 months, −10 for open dangerous-building findings, −15 for lapsed licenses. Clamped 0–100.
