How we verify our rules
- Official sources only. Every rule comes from the city, county or state's own official sources, and those sources are linked on each city page.
- Dated. Each page shows the date we last verified it.
- No guessing. If we can't confirm something from an official source, we mark it "verify" or hold the city back instead of guessing.
- Re-checked on a schedule. We re-check cities regularly and update pages when we find a change.
- Money-back guarantee. If a rule we reported was in error, you get a full refund (refund policy).
Why not just ask an AI chatbot?
General AI chatbots can be handy, but they can mix up similar places, repeat outdated rules, and they can't check your exact address or tell you when something changes. We link the official source for every rule so you can see it yourself.
No source is perfect, and rules can change after we check them. That's why each page shows its verified date and links its sources, and why we offer alerts and a refund on errors.
Not legal or tax advice. Last verified Oct 24, 2026. Rules and rates change: confirm with the official sources linked before you rent or file.
