Bought a Chestnut Hill home and wondering what you can change outside? You are not alone. Between local and national historic listings, it can be hard to know what rules apply. This guide explains how to confirm your property’s status, what exterior work needs approval in Philadelphia, and where to get help before you start. Let’s dive in.
Chestnut Hill includes areas listed on the National Register of Historic Places and areas designated locally by the Philadelphia Historical Commission. The National Register is an honor that documents significance and can open the door to certain incentives, but it does not restrict a private owner’s alterations by itself unless federal funding or permits are involved. Local designation by the Philadelphia Historical Commission is regulatory and controls certain exterior changes visible from public ways. Within a local district, properties are often labeled contributing or non‑contributing, and that classification influences how changes are evaluated.
Start by gathering the basics: your street address and, if you have it, the Philadelphia parcel identifier. The address is usually enough for an initial search. You want to confirm whether your home is individually designated, inside a local historic district, and whether it is contributing or non‑contributing.
Check the Philadelphia Historical Commission’s lists and maps for local districts and individual landmarks. PHC staff can confirm your address and tell you whether your property is contributing or non‑contributing. If online tools are unclear, request a written determination from PHC; a simple email works and gives you documentation for lenders or contractors.
Philadelphia’s property and GIS map tools typically include layers that show historic district boundaries and landmarks. Enter your address and look for the historic overlays. These tools help you visualize if your parcel sits inside a local district.
Use the National Register database to see if your property is listed and to view nomination documents and boundaries. You can also consult Pennsylvania’s state records, which often include the same National Register forms and local context. These sources are helpful for understanding why the area is significant, even though local rules govern approvals.
In Philadelphia, local designation is the main trigger for review. The Philadelphia Historical Commission issues a Certificate of Appropriateness for exterior changes that affect locally designated properties or any property within a local historic district.
Routine maintenance and in‑kind repairs are often simpler. If you replace with the same material and design, staff may be able to approve it more quickly. Replacements with different materials or profiles typically need closer review.
Expect smaller, clearly compatible projects to be handled by PHC staff. Larger or more complex proposals, like new construction, major additions, or demolition, usually go to a full Commission hearing. Plan extra time for those hearings and build that time into your schedule.
Historic review and building permits are separate. A Certificate of Appropriateness does not replace your Department of Licenses & Inspections permit, and an L&I permit does not satisfy historic review. Do not start visible exterior work without all required approvals. You risk stop‑work orders, fines, and orders to restore previous conditions.
Emergency work to prevent immediate damage is often allowed. Notify PHC and L&I as soon as possible and be prepared to submit documentation after the fact. Confirm the steps with PHC before you proceed whenever you can.
