The Adams appeal process
Four stages, one shot per year.
Step 1
Notice of Valuation arrives
Colorado counties mail Notice of Valuation in early May of odd-numbered (reassessment) years. The number on this notice is what we're contesting.
Step 2
Protest filed with the County Assessor
We submit a written protest, your evidence, and a recommended value during the county's protest window — sign up any time and we handle the timing.
Step 3
County Board of Equalization (if needed)
If the assessor denies us, the Board hears appeals through July. We escalate automatically when it makes sense to.
Step 4
Result and refund
An accepted reduction shows up on your next tax bill — and triggers a refund or credit on any tax already paid.
The arguments that actually win in Adams.
Every county weighs evidence a little differently. Here's where Adams appeals tend to succeed.
Comparable sales are stronger than yours
Recent sales near you that priced below the assessor's implied value — the single most common winning argument.
Condition issues the assessor never saw
Foundation, roof, original kitchens, deferred maintenance — none of which show up in a mass-appraisal model.
Comp pool that doesn't actually compare
If the assessor used new construction or renovated homes to value your unrenovated 1920s bungalow, that's a fix.
Market moved between the appraisal date and now
Colorado uses a fixed appraisal date. We can argue value based on a more current — and often more accurate — read.
