What it costs
Nothing, today. The federal floor is open to anyone with no account at all. Everything a state, city or territory adds on top of it — which is where compliance actually bites — needs an account, and that account is free.

With an account
$0 during early access
Everything above the federal floor. An email address, no card.
- All 2230 state, city and territory rules across 93 jurisdictions — and every one added next
- Watchlist: add a property and the atlas watches the source documents behind its rules
- Change alerts — when a document is reissued or stops responding, with the rules it affects
- Checklist exports for audit files, every line carrying its citation
- Priority on coverage requests — your jurisdictions move to the front
- Those alerts delivered by email rather than on the page in build
Early access. There is no billing: no card is taken and no one is charged. We have not set a price, so nothing here promises one. If that changes, accounts created now keep their access to what they can already read — that is a commitment, not a discount on a number we have not named. Items marked “in build” are not available today. Corpus 0.9.5 currently holds 2895 rules traced to 870 source documents.
