Published by Maryland SDAT as assessment data, separately from the county’s permit record above, and current as of the state’s own assessment cycle rather than today. An assessment can lag construction by a cycle, so a property with a recently issued permit may still be assessed as it was before the work. Owner details are published by the jurisdiction but are deliberately not shown here.

What this page cannot show

These are the permits published by the jurisdictions listed above. A project usually depends on approvals from other agencies that publish nothing machine-readable — a forest conservation exemption, a well completion report, a sediment control or grading plan, a utility connection, a homeowners’ association sign-off. Their absence here is not evidence they were not required, and the gaps between the dates above are usually where they happened. Rows labelled “Filed” are permit APPLICATIONS — Montgomery County publishes an intake date and a declared valuation. Records are grouped by normalised address text, so the same property may also appear upstream under a different spelling. Verify scope, dates, and contractor information with the issuing jurisdiction before bidding, quoting, or performing work.
