The $56-a-unit process requires landlords to be up-to-date on their property taxes and for the properties to be free of any safety or building-code violations.Since landlords are not legally permitted to collect rent from tenants of a home with an inactive license, the system is designed to serve as a check on property owners, forcing them to address safety violations and pay their taxes.But Philadelphia’s Department of Licenses and Inspections lacks the resources to hunt down property owners who flout those rules, said Karen Guss, a spokesperson for the agency.
