1,000 jurisdictions, each compiled from its own code: area formula, sign-type limits, permits, and the department that has jurisdiction — with the confidence tier, and what the documentation doesn't define shown, not hidden.
Plain language — describe the job, not a form. Answers come from the bank: the 1,000-jurisdiction sign-code corpus and the docket of shop claims. Every answer shows its backing and its tier. If the bank doesn't hold it yet, the question goes to the research queue and the answer lands on a private page — nobody invents one.
Reference only. Compiled from the cited code as of the date shown; ordinances change. Confirm with the authority having jurisdiction before designing or permitting a sign.
