Philadelphia L&I inspection and contractor recommendations

[LaJuan Tucker]

Hello I am new to Bigger Pockets. I have a duplex in Philadelphia that I've acquired from a family member. I have never rented myself before and the house is older and in need of some repairs in order to rent out the larger portion of the building. I am not sure where to start with repairs. Since the building is older (but relatively well maintained) I am imagine there are some updates that need to be done to comply with rental requirements. Where do I go to get the information needed to know which repairs are needed in order to pass inspection. My instinct is to schedule an License and Inspection appointment then have the contractor out to conduct repairs. Is this the correct order to do things? Do I contact L&I first, are there any negative consequences to having them come out more than once etc? I just don't have any idea what underlying repairs may need to be done in order to rent the duplex out. Second question is for recommendations for reliable contractors in the Philadelphia/Overbrook area. I am reading the Rental Property Investing book by Brandon Turner which has been extremely helpful. 

Thanks for advice offered
