Local tips for Philadelphia
Philadelphia has its own licensing rules that go beyond state law: the city's Department of Licenses and Inspections (L+I) issues contractor licenses, permits and trade licenses, so plumbers, electricians and contractors working in the city need an L+I license on top of any state registration.
SEPTA's subway, trolley and bus network covers most of the city, so check whether a business is near a Market-Frankford or Broad Street Line station if you don't drive. Street parking in Center City is limited and enforced by the Philadelphia Parking Authority.
Philadelphia is in Philadelphia County, and local phone numbers use the 215, 267 and 445 area codes. Popular areas include Center City, Old City, Fishtown, Northern Liberties, South Philly, University City, Manayunk, Chestnut Hill.
