Maricopa County Assessor[2] provides the official assessment notices and appeal portal for taxable value questions.

How valuations are set in Glendale

The Maricopa County Assessor determines assessed value using statutory methods, market data, and defined appraisal processes; the City of Glendale does not set assessed values but may affect value through zoning, permits, and code enforcement actions. For details on assessment methodology and how to request a review, consult the county assessor’s resources and valuation notices. [2]

What commonly affects assessed value

  • Renovations, additions, and permitted work that increase market value.
  • Unpermitted work discovered by the city or county during inspections.
  • Comparables and recent sales in the neighborhood used by the assessor.
  • Exemptions and classification claims filed with the assessor.
Exemptions or classification changes must be filed with the assessor to affect taxable value.

Penalties & Enforcement

Enforcement of municipal code provisions that can affect property condition, occupancy, or safety (which in turn can influence valuation) is handled by the City of Glendale Code Enforcement and related departments; specific penalty amounts and schedules are set in the Glendale Code of Ordinances or department enforcement policies.
