Architect seal requirements by state

Seal requirements for architects in every US state, the District of Columbia, Puerto Rico and two Canadian provinces. In most jurisdictions architects are licensed by a different board than engineers, under a different rule.

Each entry gives the licensing board, the wording the rule requires on the seal, the diameter it sets, and whether an expiration date, a signature date or a city has to appear — with a link to the provision it comes from.
