Butler County, Pennsylvania Eviction Risk: Low

Butler County carries an average eviction-risk score of 3.9/10, placing it in the Moderate tier across its 32 tracked cities. Within Pennsylvania, the county sits at rank 38 of 67, meaning 37 counties are riskier and 29 are more landlord-friendly, putting Butler squarely in the middle third of the state.

Court filing fees run $130 to $250, sheriff lockout fees add $50 to $150, and attorney fees, if needed, range from $500 to $3,000. Pennsylvania eviction costs therefore vary widely depending on whether a tenant contests the action.
