Pittsburgh Mayor Ed Gainey issued an executive order directing the Finance and Law Departments to review tax-exempt properties owned by charities.

The move was made to ensure it is appropriate under Pennsylvania law.

The mayor released a statement Wednesday.

“In the City of Pittsburgh, 34% of the property is designed as tax-exempt, that is, the owners are not paying any property taxes,” the statement reads.

“The only properties that should not be subject to any property taxes are those owned by purely public charities- places where people who are down on their luck get the services they need.”

The Finance and Law Departments will conduct a systematic review of all tax-exempt properties owned by charities in the city, but the review doesn’t include any churches or religious institutions in the city.
