Denver Assessor Records Index Map: Late 1800s to the 1950s

The Denver Assessor Records from the late 1800’s to the 1950’s are handwritten ledgers arranged by Addition or Subdivision name that have been digitized and are searchable by clicking on the pin for your block on the map.

In order to search these volumes, you will need the Legal Description of the property which includes the Subdivision or Addition name and the Block and Lot numbers of the specific property.  These can be found on title deeds or tax records. You can also obtain this information online through the Denver Assessor’s Office.

The records for each Block are arranged by Lot number (the Description column). New pages were added on top of older ones so the earliest transactions are usually found on the last page. By following the chain of Grantor/Grantee numbers, you will be able to see the chain of ownership of your property, but there is usually no indication of whether or not there is a structure on the property.

The references to Book and Page number refer to the Grantor/Grantee deed books which are the legal documentation concerning property transfers. The State Archives has the deed books up to 1902 and many after that time until approximately 1913. The other source for these books is the Clerk and Recorders Office of the City of Denver.

You can now access the Grantor Grantee Records for 1859-1884 in the Digital Collections.
