We are working on a project with three towers (30 floors above grade) with a common base (ground floor and the first two floors are shared by the three towers).
Two towers are multi-family residential with 765 parking spaces, in 5th to 2nd basement. The other tower is a hotel with 90 parking spaces placed in the first basement.
According to LEED v4, 2% of the parking spaces need to have EVSE, therefore, 18 chargers must be installed.
Do these EVSE need to be proportionally distributed between the residential and hotel parking spaces? Or can we have 9 EVSE for hotel and 9 for residential parking spaces?
We understand that the preferred parking for green vehicles need to be proportionally distributed among various parking sections (e.g. between short-term and long-term spaces), as stated in the requirments section of the BD+C Guide.

Per the v4 reference guide,Step by Step Guidance, "For Option 1, EVSE for plug-in electric vehicles or battery switching stations may be located in any area of the parking facility. Parking spaces reserved for EVSE may not contribute toward preferred parking spaces for green vehicles."
From what I recall about putting together guidance on this credit at GBCI, the location requirement doesn't exist for the charging stations because unlike preferred parking which just needs a sign or paint, charging stations rely on the location of electrical infrastructure. It would not be realistic to expect project teams to locate/distribute chargers in any particular way because they simply need to be where the wiring is.
I don't know for sure that a reviewer won't give someone a hard time for excluding a subset of occupants (like if you had zero chargers in the hotel section) but there should be no problem with chargers being available and just not perfectly proportional.
