Digital service review · Gunnison County, Colorado

Assessor Website Audit

Three independent AI reviews — ChatGPT, Gemini, and Claude — scored gunnisoncounty.org's assessor pages against the same 100‑point civic-service rubric between September 15 and September 28, 2026. Total scores land between 60 and 78. All three flag the same underlying problem from different angles: the site is strong on data tools, weak on keeping deadlines and forms current.

Review window: Sept 15–28, 2026 Rubric: 7 categories / 100 pts Statewide benchmark: 24 of 64 counties scored (Gemini run) Site reviewed: gunnisoncounty.org/132/Assessors-Office

How the three reviews scored each category

Each bar is that category's score as a share of its rubric maximum, so categories worth different points compare fairly. Claude did not test usability or accessibility directly and marked both as estimates from the assessor office's own internal review — shown hatched.

* Claude estimate, based on the assessor office's own September 11, 2026 internal review rather than an independent test. Widest disagreement is in Currency & Trust (30%–80%) and Self‑Service Tasks (55%–85%) — the two categories most affected by the deadline problem above.

Where Gunnison sits among 24 benchmarked counties

Only the Gemini review scored enough counties to support a real ranking — 24 of Colorado's 64, chosen to span Front Range, mountain-resort, and rural jurisdictions. The other 40 counties were catalogued but not scored, and are excluded here rather than shown as zeros.

Gunnison ranks 12th of 24 — squarely median for this sample, ahead of every county running static third-party listings only, behind every county with a working online appeal portal (Douglas, Weld, Boulder, Larimer, Denver, Eagle, El Paso).

Consolidated action plan

The ten recommendations below merge overlapping findings from all three reviews into one prioritized list, so duplicate advice ("fix the deadline," said three ways) becomes one line item.

P0 · Critical Fix before the next filing cycle
Appeal & exemption deadlines are wrong under new state law
Correct every mention to June 1 (real property) and July 15 / Aug 15 late (disabled veteran); add a "deadlines last verified" date stamp; confirm whether Gunnison's alternate procedures shift the personal-property dates too.
Claude
Impact Very high · Effort Low
The 2026 appeals calendar contradicts itself
The Appeals page states June 8 as the real‑property deadline, then separately says postmarked-after-June-9 protests are rejected and online protests close June 8. Make one sentence the sole authority per submission method and remove the conflicting row.
ChatGPT Gemini
Impact Very high · Effort Low
P1 · Serious Fix this update cycle
Tax worked-example uses stale assessment rates
The FAQ's estimate walk-through still uses 6.95% / 27.9% / a 5.5% revenue limit. Current 2026 rates are 7.05% (school) and 6.8% (local government) residential, 26% vacant/commercial, 25% agricultural. Replace with a dated 2026 example showing both assessed values, modelled on Larimer's "Value Flow Chart."
ChatGPT Gemini Claude
Impact High · Effort Medium
Every self-service task ends in a mailed, emailed, or faxed PDF
No appeal, address-change, or exemption request gets a confirmation receipt or status. Build online forms with e‑signature and automatic receipts, modelled on Douglas, Weld, Eagle, El Paso, and Mesa counties' online appeal portals.
ChatGPT Gemini Claude
Impact High · Effort Medium–high
Exemption & classification forms are stale and confusing
Senior, veteran, spouse and Qualified Senior forms are labelled 2024/2025; the senior page says "two groups" while its parent page says "three"; the forms list has a "Gold Sar Spouse" typo. Add a short eligibility guide above the form list, verify and re-date every file, and fix the typos.

Impact High · Effort Medium
P2 · Monitor Plan for the next redesign pass
No task-based entry point on the main Assessor page
Owners must already know which page covers their goal. Add an "I want to…" hub: find my property · understand my value · appeal · apply for an exemption · change my address · pay my taxes — with the Treasurer handoff labelled explicitly.
ChatGPT Gemini Claude
Impact Medium · Effort Low
Spatialest/Comper handoff is confusing
Recurring cache-reload errors, no stated value-year or refresh date, and the Community Portal's page description still reads "Welcome to Riverside County Assessor." Fix the vendor template text and caching issue, and add cross-links back to appeal and exemption pages.
Gemini Claude
Impact Medium · Effort Medium
Mobile and accessibility performance is unverified
All three reviews flagged this as an estimate, not a tested result. The office's own internal check already found a mobile alert banner clipping its heading at 390px width. Run a real keyboard, screen-reader, contrast, and mobile-viewport audit and fix what it finds.
ChatGPT Gemini Claude
Impact Potentially high · Effort Medium–high
No interactive property-tax estimator
Owners can see their new value but can't translate it into an expected bill. Add a value → assessed value → mill-levy estimator, modelled on Boulder's or Weld's tools.
Gemini Claude
Impact Medium · Effort Medium–high
Leftover content debt: duplicate pages, stale Quick Links
Two separate pages are both titled "Recent Legislation" (/1062, /1063); the homepage's "2026 Assessor's Report" and "2026 Abstract of Assessment" Quick Links still point to 2023 PDF filenames. Merge the duplicates and relink to the current files before the next publish.

What's already working

Every review independently called out the same strengths — the fixes above are about currency and completion, not a rebuild.

✓
Three linked data tools A property-record search, a map-based Community Portal, and the Comper comparable-sales builder all work from one owner journey.
✓
Downloadable data & e-notices Bulk database exports with data definitions, plus eNoticesOnline for paperless Notices of Valuation and tax statements.
✓
Unusually candid explanations Plain-language coverage of market/cost/income approaches, what counts as a valid appeal reason, and what the Assessor's office does and doesn't control.
✓
Complete appeal chain Notice of Determination, County Board of Equalization, and the next-step options (Board of Assessment Appeals, district court, arbitration) are all documented end to end.

Review the public-facing assessor websites for all 64 Colorado counties. My main goal is to understand where Gunnison County stands statewide and how its website could better serve property owners.

Rubric — same 100 points for every county

CategoryPtsEvaluate
Findability and organization15How easily can a resident find property search, appeals, exemptions, forms, and contact information? Are navigation labels clear?
Property search and public data20Can a user find a parcel by address or account number and view useful values, property details, sales information, and maps? Are the data and their dates explained?
Self-service tasks20Can an owner find and complete or submit common requests, including an appeal, address change, exemption application, property-record correction, or information request?
Explanations and transparency15Does the site explain how property is valued, why a value may change, what the assessor controls, and how value relates to taxes?
Usability across devices10Do menus, searches, forms, and linked portals work clearly on desktop and mobile?
Accessibility10Are core tasks usable with a keyboard, readable text and contrast, meaningful link labels, and accessible forms or documents?
Currency and trust10Are deadlines, rates, notices, contact details, and resources current and clearly dated where appropriate?

Assign letter grades of A (90–100), B (80–89), C (70–79), D (60–69), or F (below 60). Do not award an A if property search is unusable, appeal instructions are materially wrong or missing, or a major accessibility barrier blocks a core task. State the reason if this rule limits a county's grade.

Three tasks, attempted for every county

  1. Find a property record using an address or account/parcel number.
  2. Find the current instructions and deadline for appealing a property value.
  3. Find how to apply for an exemption or correct property information.

Scoring rules

Give every county a numeric score, letter grade, category scores, and brief evidence with links to the pages or tools examined. Distinguish missing, broken, and could not verify. Do not assume a search tool works merely because its link exists. Note when a task moves to a treasurer, GIS, vendor, or other external portal, and assess whether that handoff is understandable. Do not count a service as missing if it is available through a clearly linked external portal.

For each category, explain what earned or lost points using observed evidence. Apply the same scoring standard to every county: award full points when the relevant information or task is easy to find, clear, current, and usable; partial points when it is available but difficult to find, confusing, incomplete, or cumbersome; and zero when it is absent or unusable. Do not treat an unverified feature as missing or award it full credit. Record what you could verify, identify the uncertainty, and explain how it affects the score. Base grades on the property-owner experience, not visual appearance alone.

Gunnison-only depth

Provide detailed improvement recommendations only for Gunnison County. Test Gunnison's full property-owner journey more thoroughly, including finding a record, understanding its value and property details, appealing, finding forms and exemptions, correcting information, and understanding property taxes. For each recommendation, identify the specific problem, the proposed change, why it would help an owner, and its estimated impact and implementation effort. Rank the recommendations by priority. Link to working examples from other Colorado counties when they offer a useful model.

Required order of results

  1. A table of all 64 counties, sorted by score.
  2. Gunnison County's statewide rank and percentile, plus its category scores compared with the statewide median and the highest-scoring counties.
  3. Gunnison's strengths and the specific points where a property owner may get stuck.
  4. Gunnison-only recommendations, ranked by priority.
  5. A short methods section stating the review date, how many of the 64 sites and external portals were actually tested, any limitations, and which findings need manual verification.

Dashboard-ready data

Also provide dashboard-ready data as downloadable CSV files or a single JSON file. Include one record per county with its name, assessor website URL, review date, seven category scores, total score, letter grade, statewide rank, verification status, and brief summary. Provide separate records for Gunnison's recommendations with the issue, proposed change, priority, expected owner impact, estimated effort, and implementation status. Use consistent field names and values. Keep evidence links in the data, use null for scores that cannot be verified, and do not combine multiple counties or recommendations into a single record. Structure the files so they can be used to build a simple interactive dashboard and updated after manual review.

Guardrails against overclaiming

If you cannot examine all 64 counties thoroughly, say so plainly. Do not present a partial sample as a definitive statewide ranking or percentile. Identify which counties were reviewed, label the comparison provisional, and leave unreviewed scores and ranks blank. Do not invent findings or links to fill gaps.
