Office of Property Assessment

Determining accurate and fair property values and providing property information.

Office of Property Assessment

What we do

The Office of Property Assessment (OPA) determines what every piece of property within Philadelphia is worth. The assessed dollar value is used to calculate the property’s real estate tax due. Real estate tax – also known as property tax – provides a big part of our City’s public school funding.

We also handle abatement and exemption programs that may reduce a property’s real estate tax bill, including:

  • Disabled veterans real estate tax exemption.
  • Nonprofit exemption.
  • Catastrophic loss exemption.
  • Abatement programs for new construction or substantial renovation.

If a property owner disagrees with an assessment or believes that an abatement or exemption has not been properly applied, they can submit an inquiry to the OPA or appeal.

You can search and compare property values through the City’s online property search application.
