As part of the Department of Planning and Development, the Philadelphia Historical Commission protects the City’s historic resources. Together with its advisory committees, the commission:

• Identifies and designates historic landmarks.
• Maintains the Philadelphia Register of Historic Places.
• Hosts public meetings about historic properties.
• Works with property owners to protect landmarks.

The commission staff reviews building permit applications and nominations to the register. When needed, they forward applications to the appropriate committee. The staff:

• Approves over 90% of building permit applications without referral to a committee.
• Informs the public about the commission’s rules and processes.
• Gives advice on preservation techniques.
• Helps the public research the history of their properties.
