About the Denver Property Market
Denver is a city located in Adams County, Colorado. Every property inside the Denver city limits is assessed by the Adams County assessor, which applies Colorado property tax rules uniformly across the county.
Because Denver property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Denver home is over-assessed have the right to file a protest directly with Adams County.
Under Colorado law, a protest cannot increase your assessed value — it can only stay the same or go down. That makes a Denver protest a low-risk way to push back against an over-assessment, especially for homeowners with strong comparable sales evidence.
Denver Property Market Context
Denver homeowners navigate the same Colorado assessment system as every other community in the state, but local market dynamics mean over-assessments here have their own character.
Colorado market character
Colorado values are reassessed on a two-year cycle, and recent cycles have produced double-digit increases along the Front Range and mountain resort communities. The residential assessment rate sits around 6.7% after recent legislation, but on fast-appreciating homes the bill still jumps sharply.
How Colorado handles protests
Colorado is protest-friendly. Assessed value cannot increase as a result of a protest, and the state runs a clear three-step appeal path: assessor, County Board of Equalization, then Board of Assessment Appeals.
When to file in Denver
Notices mail May 1. Protest window closes June 8 at the assessor level. This is one of the tightest deadlines in the country — do not wait.
