Best for: A data builder with the patience for methodology rigor and the stomach for publishing uncomfortable facts

The openingWhy this idea is overlooked

Federal workplace safety enforcement data is public, searchable, and almost unusable for a normal person: raw inspection records, citation codes, and case statuses that only a safety professional can interpret. A homeowner hiring a roofer, the trade where falls kill, has no idea this history exists, and the review sites they do check say nothing about whether a contractor sends workers onto roofs without protection.

Check contractor safety record before hiring: the honest path

Consider the steps below our honest answer to check contractor safety record before hiring: what actually works, in the order it works.

The roadmap

How to start, step by step

1
Build the grading methodology like it will be attacked
It will be. Design the letter grade with credentialed safety professionals: violation severity and recency weighting, company size normalization, and explicit handling of contested citations and companies with no inspection history, which means unknown, not perfect. Publish the full methodology and grade only what the data supports.
2
Engineer the entity-matching problem
The hard technical work is matching enforcement records to real businesses: name variations, LLC changes, and franchises. Be conservative; a wrong grade attached to the wrong company is your existential risk, so show your matching confidence and make disputes easy and fast.
3
Handle fairness and legal exposure up front
You are republishing true public records with analysis, which is defensible, but process matters: a correction pathway, timestamped data vintage on every profile, contested-citation labels, and media-law counsel review of your framing. Accuracy discipline is the entire brand.
4
Win the search moment
Profiles that rank for contractor-name searches intercept homeowners at the exact research moment. Free basic grades build the traffic; detailed homeowner reports, what the violations actually were, in plain English, carry a modest fee.
5
Give good contractors a reason to love you
Contractors with clean histories get a badge worth marketing, and safety-proud firms will pay for verified profiles and embeddable trust marks. The contractor side monetizes better than the homeowner side long-term, and it balances the site politically.
6
Expand the data layers deliberately
State license status, insurance verification prompts, and bond checks deepen the profile into a full due-diligence stop. Each layer must meet the same bar: public, sourced, dated, and disputable.
