Twelve North Carolina counties are completing countywide revaluations effective January 1, 2026: Anson, Bladen, Buncombe, Chowan, Clay, Davidson, Guilford, Harnett, Onslow, Pamlico, Pender, and Scotland. Assessment notices have been mailed February through March. For most of these counties, this is the first comprehensive property revaluation since before the pandemic. That timing creates a specific risk: mass appraisal models calibrated on 2018 and 2019 market data are being applied to a 2026 commercial property market that has bifurcated sharply along lines those models were not built to capture.

The bifurcation is well documented nationally and applies to North Carolina commercial markets as much as any other. Grocery-anchored shopping centers and experiential retail properties — entertainment, dining, fitness, specialty food — have performed at or above pre-pandemic levels. Traditional office and conventional strip retail have declined. A mass appraisal model trained on 2018-2019 market data, which did not contain the post-pandemic bifurcation, will apply pre-bifurcation parameters to both performing and distressed property types — systematically overvaluing distressed properties relative to their current market performance.

The twelve counties represent a mix of urban, suburban, and rural markets. Guilford County (Greensboro, High Point) and Buncombe County (Asheville) are the largest urban markets in the revaluation group. Davidson County (Lexington, Thomasville) is a mid-sized market. The remaining counties include smaller cities and rural areas.

The commercial property assessment implications vary by market. Guilford County's commercial market includes significant office inventory in Greensboro that is likely to have experienced post-pandemic value decline consistent with national office market trends. Buncombe County's commercial market has been affected by Hurricane Helene's October 2024 damage to the Asheville area, creating a specific local assessment challenge on top of the general revaluation risks.

Property owners in any of the twelve counties who own commercial properties that have experienced income decline since the last revaluation — which covers the entire pandemic period for most of these counties — should review their assessment notices carefully and evaluate whether the revaluation accurately captures current market value.

The Mass Appraisal Risk

County mass appraisal is a statistical process, not an individual property analysis. The county's appraisal staff or contractor develops models based on market data — sales, income, and cost information — and applies those models systematically across the property inventory. The models are calibrated on available transaction data and are designed to produce accurate assessments for the median property of each type.

The risk in a revaluation year with a long gap since the last update is that the model training data may not reflect the post-gap market conditions. Models calibrated on 2018-2019 transaction data have not been updated to reflect the 2020-2024 period of pandemic disruption, hybrid work adoption, e-commerce acceleration, and the resulting bifurcation between property categories. The models may produce accurate assessments for stable property types (single-family residential, grocery-anchored retail) while systematically over- or under-valuing property types that have experienced significant post-pandemic value changes.

The Appeal Process in North Carolina

North Carolina counties offer informal review processes in addition to the formal Board of Equalization and Review (BOE) hearing. The informal process is faster, less adversarial, and often produces assessment adjustments without requiring a formal hearing. Property owners who have documented evidence that their assessment exceeds market value should pursue informal review first — it preserves formal hearing rights while offering a faster path to resolution.

The informal review and formal BOE hearing deadlines vary by county. Property owners who received notices in February and March should verify their county's specific appeal deadlines — these are typically 30 to 90 days from the notice date, and the informal review window may be shorter than the formal hearing deadline.

Important: Assessment reductions from revaluation appeals are not retroactive. A successful appeal reduces the Tax Year 2026 assessment and all future years until the next revaluation. It does not reduce prior-year tax obligations. The value of a successful appeal is prospective, not retrospective — which is an argument for filing promptly rather than waiting to evaluate whether the cost-benefit is favorable.

What BID and DDA Owners Should Understand

North Carolina has a limited number of BIDs and special assessment districts — the state's enabling framework is less developed than many other states. But property owners within those districts who are subject to the 2026 revaluation face a specific interaction between their district assessment and their county assessment.

In value-based formula assessment districts, a county revaluation that increases assessed value will increase the district assessment obligation proportionally. In the twelve revaluation counties, owners in any value-based assessment district should model how the revaluation affects their total property tax and assessment burden — county, municipal, and district combined. A revaluation that significantly increases assessed value in a previously undervalued property category can produce total burden increases that merit challenge.
