This guide explains where to request the valuation notice, which office enforces assessments, how to start an appeal, common deadlines and practical steps to preserve your rights under Denver and Colorado procedures.

How to request a valuation notice

Property valuation notices are produced by the City and County of Denver Assessor. To request your notice or a copy of the valuation worksheet, contact the Assessor’s Office directly or use the assessor pages linked below for online requests and forms.[1]

  • Request method: in person, by mail, or via the Assessor’s online services when available.
  • Required information: property address or parcel number, owner name, and identification.
  • Timing: valuation notices are typically issued annually; check the Assessor’s page for the current mailing schedule.[1]
Ask for the valuation worksheet to see comparable sales and valuation adjustments.

Penalties & Enforcement

The Assessor determines taxable value; the Treasurer and Revenue offices handle tax billing and collection. Penalties and interest for unpaid property taxes are governed by state and county collection procedures rather than by the valuation notice itself. Specific fine amounts or interest rates related to valuation requests or missed appeals are not specified on the cited pages; see the enforcing offices for collection penalties.[1]

  • Fines/fees: not specified on the cited page.
  • Escalation: not specified on the cited page; collection and enforcement steps are handled per Denver Treasury and Colorado statutes.
  • Non-monetary sanctions: administrative collection actions, tax liens, and referral to court for tax delinquency are possible under county procedures.
  • Enforcer: City and County of Denver Assessor (valuation), Denver Treasurer or Revenue (collection); appeals may involve county or state boards.[2]
  • Inspection and complaints: contact the Assessor’s Office for valuation review requests and the Treasurer for billing disputes.
  • Appeals and time limits: specific appeal deadlines are not specified on the cited Assessor page; consult the Division of Property Taxation and the Assessor for current filing deadlines.[2]
Missing an appeal deadline can forfeit your review rights.

Applications & Forms

The Denver Assessor provides request and information pages for valuation details; formal appeal or protest forms and filing instructions are published by Colorado’s Division of Property Taxation and by county offices. If a named form or fee is required it will be posted on the official pages cited below.[2]

Action steps

  • Request your valuation notice from the Assessor as soon as you receive the mailed notice or when preparing to appeal.
  • Collect supporting evidence: recent sales, repair invoices, photos and appraisal reports.
  • File an appeal using the county or state process within the time limit stated on the notice or the official guidance.
  • Pay any required filing fees if the official form or page specifies them; fee amounts should be confirmed on the cited official pages.
