Property TaxValuation

PT-VAL-01

Start with an assessment method the city can actually keep current

Choose an assessment basis that fits the city’s data and capacity, rather than importing a technically elegant system that cannot be maintained. In many contexts this means starting with a simpler, rule-based method that can later become more market-linked as data improve.

PT-VAL-02

Use simple location and property bands to improve fairness quickly

Improve fairness by using simple bands based on factors such as location, use, size, or building type rather than treating very different properties too similarly. This is often the most practical first step toward a more defensible assessment system.

PT-VAL-04

Revalue first where the money and change are concentrated

Start revaluation in zones or segments where values, change, or revenue are concentrated, rather than trying to update everything at once. This makes the first revaluation more manageable and often delivers faster revenue and fairness gains.

PT-VAL-03

Bring sales, rents, and build-cost evidence into assessments

Use market evidence—sales, rents, construction costs, or land values—to anchor assessments more credibly. Even if the city cannot yet run advanced models, better evidence helps move valuations closer to current realities and makes them easier to defend.

PT-VAL-05

Move to mass valuation when data and capacity allow

Use structured mass valuation methods to produce values more accurately, efficiently, and consistently across large numbers of properties. This is the scalable option once the city has enough data, quality control, and institutional capacity to support it.

PT-VAL-10

Tighten valuation data and quality control

Improve the consistency of valuation data, testing, and sign-off so that assessments are easier to defend and more consistent across similar properties. Quality control is often the difference between a reform that survives and one that collapses into distrust.

PT-VAL-06

Update values between full revaluations

Use simple interim adjustments—such as indexation, area-value updates, or targeted recalibration—to stop assessments from becoming stale between major revaluations. This helps preserve credibility and revenue without rerunning a full citywide exercise every year.

Put revaluations on a rolling cycle

Move from sporadic, politically delayed revaluations to a predictable cycle with clear responsibility, budget, and timing. Regularity matters because equity and credibility decay when revaluations happen only after long gaps.

PT-VAL-08

Review exemptions, reliefs, and classifications that distort bills

Check whether property classifications, exemptions, reliefs, or bands are being applied accurately and whether they still make sense in practice. In many cities, assessment fairness problems are partly driven by misclassification or overuse of special treatment rather than valuation alone.

PT-VAL-09

Create a clear, time-bound valuation review and appeal process

Provide a simple administrative route for taxpayers to question values, classifications, or major factual assumptions within a clear time window. A credible review process makes valuation reform easier to defend and helps surface recurring errors.
