@Eric DeVito, depends where the property is. That is for Allentown city, not everything with an Allentown mailing address. South Whitehall township uses an Allentown mailing address but is a different municipality than the city, for instance. Best to contact the local municipality directly so you know first hand. It's a simple phone call, explain what your intentions are, where the property is and ask what requirements there are for landlords. I'm sure you'll find most will be more than happy to help a landlord that's is looking to follow the local guidelines. I believe Allentown also has a packet specifically for Landlords that they will direct you to.
Also, there are different levels and qualities of property management. You may be able to have a limited management service that satisfies the local requirement but is cost effective and allows you to retain some aspects of management. I don't know firsthand, but something I would ask if that's the direction you want to go.
