Scope of the 2025 Reassessment
In Colorado, property tax reassessments occur on a two-year cycle and are conducted statewide in all 64 counties. For the 2025 cycle, every commercial property in the state will receive a new assessed value, based on market conditions as of June 30, 2024.
While all counties are reassessing, material impact should be expected in key metro markets such as:
- Denver County
- Adams County
- Arapahoe County
- Douglas County
- Jefferson County
These areas reflect a significant share of Colorado’s commercial real estate activity and contain submarkets where assessed values may not align with current market performance.

Valuation Outlook
The 2025 reassessment is expected to produce meaningful shifts in assessed values across Colorado — from Denver’s central business district to high-demand resort counties. While some asset types have stabilized, others continue to face structural or policy-driven challenges that may not be fully reflected in mass appraisal models.
Assessment risks are especially pronounced in areas with elevated vacancy, outdated cost models, or recent development surges. In places like Denver, an influx of new multifamily supply and lingering office vacancies are reshaping tax burdens — even if overall tax revenue remains flat. Meanwhile, retail and hospitality valuations are diverging significantly by format and location, and industrial properties may be overvalued if models haven’t caught up with shifting cap rates.
Many taxpayers may still see higher tax bills due to lagging valuation inputs and uneven application of local cost or income factors. These shifts are likely to redistribute the tax load across property types and geographies — often in ways that create appeal opportunities.
Valuation Trends by Property Type
| Property Type | Expected Trend | Notes |
|---|---|---|
| Office | ↓ | Demand suppressed by vacancy and remote work |
| Multifamily | ↓ | Softening due to oversupply and rising costs |
| Retail | Mixed | Performance varies by format and location |
| Industrial | ↑ | Strong demand, but overvaluation risk exists |
| Hospitality | Mixed | Limited-service lags; luxury assets stronger |
DMA continues to monitor these dynamics and will flag opportunities where commercial real estate valuations appear inflated or misaligned with real-time market performance.
Why Early Preparation Matters
Reassessments often lead to thousands of appeals being filed across affected jurisdictions. Many offer an informal review period ahead of the formal appeal deadline—making early engagement especially valuable, as it can lead to faster, lower-cost resolutions.
