special license for 3+ people - can I pass fee onto tenant?

[Fran Flanagan]

The town where my single family rental has additional charges to allow 3+ unrelated persons in the residence. My house meets the requirements, which are basically:
- 1000+ sf
- 20+ "front feet" or lot width
- one off-street parking spot for each person over 2.

The township charges you a $200 application fee + $135 annual fee for 3+ people. This is in addition to the other $175 annual fees for rental properties in town, good times.

I'm asking $1750/month and getting significant interest as its a nice place in a popular area. If I select a group of applicants who have 3+ people, can I ask them for any more money towards this? I'm not sure if this would be construed as violating any of the protected classes in PA. My thought was to ask them for the $200 and pay the $135 myself. Is this legal? ethical? Any thoughts appreciated.
