Philadelphia Department of Licenses and Inspections

Philadelphia's Department of Licenses and Inspections provides official resources about business and building licenses, permits, inspections, and code-related responsibilities. Its website serves residents, property owners, businesses, and professionals.

The activity, property, project, and applicant role determine the actual process and documents required. A general guide or submitted application is not an approval. Other city, state, or federal authorities may have connected requirements that are handled through separate processes.
