AI Analysis
This bill strengthens transparency in property tax appeals by requiring county assessors to share the data and methods they use to value property, and sets stricter deadlines for exchanging evidence before hearings. It also gives boards of equalization tools to enforce these rules.
- Requires county assessors to provide property owners with a list of comparable sales (or other valuation factors and property addresses) used to determine their property's assessed value, upon request.
- Mandates that assessors disclose this valuation evidence at least 28 business days before the property owner’s hearing before the board of equalization (up from the previous 21 days).
- Bars assessors from changing the valuation evidence after disclosure unless new evidence is found — in which case the new evidence must be shared with the owner and board at least 28 business days before the hearing.
- Allows property owners to list comparable sales in their appeal notice, but prohibits them from changing those sales later unless new evidence is found — with the same 21-day advance disclosure rule to the assessor and board.
- Gives boards of equalization authority to continue a hearing or exclude evidence if either party fails to meet the disclosure deadlines.
Who is affected
- Property owners — Homeowners and property owners who believe their property is overvalued and file an appeal with the county board of equalization.
- County assessors — County assessors who must disclose valuation methods and supporting data to property owners during the appeal process.
- Boards of equalization — County boards of equalization, which must manage appeals and enforce disclosure deadlines for evidence.
Pro/Con Analysis
Stronger case for benefits
Potential Benefits (5)
Enhances due process rights for property owners by guaranteeing access to the comparable sales and valuation factors used to assess their property, enabling more informed and effective appeals.
Rights & LibertiesPeopleRef: Sec. 1(1)Strengthens fairness in the appeal process by requiring assessors to disclose evidence 28 business days before the hearing (up from 21), giving property owners more time to prepare a rebuttal and reducing last-minute surprises.
HousingPeopleRef: Sec. 1(2)Creates consistent procedural rules for evidence disclosure and limits post-disclosure changes, reducing arbitrary or last-minute valuation adjustments and promoting more predictable assessment outcomes.
Local GovernmentPeopleRef: Sec. 1(2)Empowers property owners to list comparable sales in their appeal and protects them from being penalized for changing those only if new evidence emerges—leveling the procedural playing field with assessors.
HousingPeopleRef: Sec. 1(2)Grants boards of equalization authority to exclude untimely evidence or continue hearings, improving procedural integrity and discouraging tactical delays or last-minute evidence dumping by either party.
Local GovernmentPeopleRef: Sec. 1(2)
Potential Concerns (3)
Increases administrative burden on county assessors by requiring timely disclosure of valuation evidence and imposing penalties for late changes, which may strain limited county resources—especially in smaller or under-resourced counties.
Local GovernmentLean peopleRef: Sec. 1(2)May delay property tax appeals due to mandatory 28-day disclosure windows and potential hearing continuances, which could slow resolution of disputes and prolong uncertainty for homeowners during appeals.
Public SafetyLean peopleRef: Sec. 1(2)While intended to help property owners, the requirement that assessors cannot change valuation evidence after disclosure may reduce flexibility in cases where new data (e.g., market shifts, corrected records) emerges—potentially locking in inaccurate valuations if assessors are unable to correct errors post-disclosure.

Who Is Most Affected
Homeowners—especially those in high-appreciation or rapidly changing markets—gain stronger tools to challenge overvaluations with full transparency, reducing the risk of unfair tax burdens due to opaque or outdated assessments.
County assessors face increased procedural obligations and reduced flexibility to adjust valuations post-disclosure, which may strain staffing and require additional training or system upgrades—particularly in counties with limited resources.
Boards of equalization gain stronger procedural authority to manage appeals fairly and efficiently, but may face increased caseloads or complexity due to more contested appeals enabled by greater transparency.
Property owners with limited means or legal knowledge benefit most, as the bill reduces reliance on professional appraisers or attorneys to navigate opaque valuation processes—though complex cases may still require outside help.
Large property investors or developers may benefit marginally from more predictable appeal timelines, but the bill does not create new financial advantages for them—unlike tax cuts or exemptions, this is procedural fairness, not economic advantage.
