Denver Assessor Records

The Denver Assessor Records provide an index to City of Denver Grantor/Grantee information and can give a chain of ownership of Denver property by legal description (addition, block and lot numbers) or parcel number, but there is generally no indication of whether or not there is a structure on the property. The earliest records from the 1870's to 1917 are on microfilm in the Western History/Genealogy Department. The Digital Collections include handwritten Assessor block and lot index ledger volumes for the City of Denver from the late 1800’s to the early 1950’s indexed on an interactive map.  Later Master Property Records are filed by parcel number and extend into the 1980’s.  For more information see the Denver Building History Tutorial.
