I am working on a CI project that is located in a single tenant building that has an area more than 75% of the total building area. The building has no parking and none is subsidized. The zoning ordinance does not require any parking, so it seems I can attempt either option under Case 2, but both options require preferred parking for carpools or vanpools. I cannot provide those spaces because there is no parking at all. I noticed the v4 requirements for the Reduced Parking Footprint credit state that "Preferred parking is not required if no off-street parking is provided." Do I need to explain this and reference the v4 requirements as an alternative compliance path or as special circumstances?
