Tax certiorari
The court path for challenging assessments
Tax certiorari is the judicial proceeding for challenging a property's assessment, following administrative review by the Tax Commission. For large income-producing buildings the annual challenge is routine practice — applications filed protectively each year, settlements negotiated across years of accumulated claims, refunds and roll corrections flowing from the results.
The filings are records with analytical uses: they document the owner's claimed income and value positions, the city's responses, and the negotiated outcomes. A building's certiorari history reveals how aggressively its taxes are managed — and settlement patterns can foreshadow assessment trajectories that raw roll data has not yet caught up with.
