Electrical, mechanical, sign, fence, demolition and other trade permits are separate permit types and are not shown. Rockville and Gaithersburg issue their own building permits, which are not in the county data, so permits there are not covered. Open data updates on a delay, so the most recent records may be incomplete. For general information only — not legal, financial, or real-estate advice.
