I do not have an EVPS in front of my house, just regular street parking. I decided that I will still pay for installing a NEMA outlet at the curbside in front of my house despite not having a guaranteed/reserved spot for my car so that I have the ability to charge the car when i'm home. I'm retired and don't use the car every day so I have the ability to move the car whenever the spot in front of my house becomes available.
All the EVPS owners are in Philly are in a facebook group, if you message me directly I can add you. A good portion of us are reservation holders and I'm sure we can recommend plenty of electricians that have done this already. Some tend to increase their prices quite a bit when they hear 'Tesla', so we've found it helpful to just talk about EVs.
Also there is a hearing comping up in city council in 10 days.
City Council's Committee on Streets and Services is holding a Public Hearing on Monday, April 9, at 1:00 p.m. in Room 400, City Hall.
The agenda includes Councilmen Oh’s and Squilla’s Ordinance #180218, “An Ordinance amending Section 12-1131 of The Philadelphia Code, entitled "Electric Vehicle Parking," to provide for the discontinued approval of new Electric Vehicle Parking Spaces and the expiration of such existing spaces, all under certain terms and conditions.”
Part of their plan to wind down the program is to force the removal of curbside chargers once there is no official EV parking spot. Although you never had a spot, if they decide against allowing curbside outlets you may not be able to get one.
I specifically discussed this with city officials in person, since mine is not a built in charger, but a curbside outlet on a post on my property.
You might be in a unique position to speak up, since you are willing to have the outlet installed even without a guaranteed spot.
