Why no map on this page?
Maps are already handled better by the free tools below. This page does one thing: plain-language answers to property questions — assessed value, why it changed, how to protest.
Already better elsewhereThe county's own ArcGIS Hub, Colorado DPT, and others provide parcel maps purpose-built by mapping specialists. All listed below.
Maps create barriersInteractive maps are the hardest element to make accessible under WCAG 2.1. Removing it from this tool is the fix — not a limitation.
Nobody came here for a mapResidents come to answer four questions: value, why it changed, tax calculation, and how to protest. None require a map.
Decoupled = easier to maintainWhen mapping and data search are separate, the county can update or replace each independently without risking the other.

Resources — words and rights
Definitions for every term you might see in a property record, plus ADA contacts for both the county and the city.
WCAG 3.1.3 — AAA: definitions provided for all technical and legal terms used on this page.
- Assessed value
- The value the county assigns your property for tax purposes. In Colorado this is a percentage of market value — not what it would sell for on the open market.
- Actual value
- The county's estimate of what your property would sell for. Also called market value or appraised value. The starting point before the assessment rate is applied.
- Assessment rate
- The percentage of actual value used to calculate assessed value. Colorado's residential rate is 6.765% — set by state law, not the county.
- Mill levy
- The tax rate applied to assessed value. One mill = $1 of tax per $1,000 of assessed value. Your total combines county, city, school, and special district levies.
- Parcel number
- A unique ID for your property. Also called schedule or account number. Encodes location using the U.S. Rectangular Survey System (Township, Range, Section).
- Conveyance
- A legal transfer of property ownership — warranty deed, quit claim deed, or other deed types. Every recorded conveyance is a public record.
- Warranty deed
- The most common transfer type. The seller guarantees clear legal ownership and the full right to sell.
- Quit claim deed
- Transfers only whatever ownership the seller has — no guarantee of how much that is. Common in family transfers and divorce settlements.
- Valuation protest
- A formal request to the Assessor to review your assessed value. You have the right to file one every two years. The deadline is May 1st in odd-numbered years.
- Unincorporated
- Land within El Paso County that is not inside any city or town. El Paso County governs directly — no city council, no city utilities, no city zoning.
- Special district
- A separate local government providing one specific service — utilities, fire, water, sanitation. Your property may be in several at once, each with its own mill levy.
- Township / Range / Section
- A grid system used to describe land location. Township is north-south, Range is east-west, Section is a one-square-mile unit within the grid.
Both El Paso County and the City of Colorado Springs must meet WCAG 2.1 Level AA by April 24, 2026 under ADA Title II. If you have encountered a barrier on a county or city digital tool, contact the right authority first — then forward us what you sent and what they said.
