Every answer cites a verified section
Citations are matched against what we actually retrieved. One we cannot resolve is flagged, not quietly dropped.
How we verify
Public corrections log
When we publish something wrong, it goes on the record — what was wrong, how we found it, what changed.
Read the corrections
Checked against official sources
Permit rules and fees carry the jurisdiction’s own source document and the date it was verified.
