We pulled every residential protest decision the Douglas County Board of Equalization published in 2025 — the full set, not a sample. The data is the foundation of the model that scores cases on this site. This post summarizes what the year actually looked like, without the marketing varnish, so you can decide whether your 2026 filing is worth the time.
Filing volume
Filings rose materially against the prior year. The growth was concentrated in single-family residential parcels in newer subdivisions on the western edge of the county, where reassessments produced the largest year-over-year value increases. Older neighborhoods east of 72nd Street filed at roughly historical rates.
Who won, and by how much
Most residential protests that succeeded resulted in modest, single-digit percentage reductions. Large reductions — twenty percent and up — were rare and almost always tied to documented condition issues (storm damage, foundation problems, deferred maintenance with photos and repair estimates) rather than to clever comp selection.
The strongest predictor of a successful protest was, unsurprisingly, the strength of the comparable-sales evidence. Filings with three or more clean, well-matched comparables and an explicit requested value outperformed filings that submitted a single comp or that asked the Board to “just lower it.”
Neighborhood patterns
Without naming individual subdivisions where small sample sizes would make the numbers misleading, three broad patterns held:
- Mature, low-turnover neighborhoods with few annual sales produced fewer protests and fewer successful ones. Without comps, the case is hard to build. Unequal-appraisal arguments helped in some of these areas.
- High-turnover suburban neighborhoodson the western and southwestern edges produced the most filings and the highest success rates for owners who submitted clean evidence. The market is legible there; the assessor’s margin of error is wider.
- Mid-century inner-ring neighborhoods were a mixed set. The protests that succeeded leaned heavily on condition evidence: an honest, photo-supported account of dated kitchens, original plumbing, or roof age beat any comp-only argument.
What arguments moved decisions
Reading the file notes, three argument types accounted for the bulk of residential reductions:
- Comparable-sales evidencewith explicit adjustments. Owners who said “this comp sold for $X; subject is smaller by 150 sqft; adjusted comp is $Y” did better than owners who dropped a list of sale prices on the desk.
- Condition-based argument with photos and repair estimates. The Board responds to documented depreciation more consistently than to assertions of it.
- Recent purchase of the subject propertyat arm’s length, below the assessor’s value, when the sale was within the last twelve months and not a family transfer or short-sale.
What didn’t work
- Tax-bill arguments.“My taxes went up” is not a valid ground; the Board cannot adjust the levy.
- Zillow estimates alone. The Board does not treat automated valuation models as evidence; they appeared in many losing filings as the only support.
- Single-comp filings. One sale, no adjustments, no requested value. A high share of these were denied without an informal review meeting.
- Long narrative arguments without numbers. The Board decides on values. If you do not propose one, you make the hearing officer guess.
What this implies for 2026
If the 2026 reassessment touches your parcel, your case strength is decided before you write the protest letter — by what your block has actually been doing in the market. The protest letter’s job is to present that evidence cleanly and ask for a specific value. Owners who do that consistently outperform owners who treat the protest as a rhetorical exercise.
Aggregate outcomes do not predict your protest. They describe the pool. Whether your particular case clears the bar depends on the comp set on your street and the condition of your home.
