Notices of Value 2019

Colorado state statutes require county assessors to revalue all Real Property every two years, on the odd number year (2019).
Adams County experienced significant increases in the overall value for all residential property, reflecting the strong economic conditions across the county.
Property owners should receive their Notice of Valuation the first week in May.
A taxpayer may choose to appeal the decision of the Assessor's Office concerning the value or classification of their property for the current year.
If you would like to appeal your value and/or classification or review your Notice of Value (NOV) please click here.

The appeal period for 2019 is from May 1st to June 3rd.
