Legal Question - Use - In-Law Suite - Rental - licensing

[Max T.]

The property is a large twin, zoned RSA-3.

Two entrances:

Main entrance -  large 5 bedroom 2 bathroom, living room, and kitchen space.

Rear entrance  - 1 bedroom, 1 bathroom, living room, and kitchen. 

In Philadelphia could an owner-occupant live in the larger space and rent out the in-law suite? Would the city allow for this and issue a rental license for the in-law suite? The utilities are not separated, however, both living spaces have their own entrances, kitchens, and bathrooms.
