If more than 10% of the total project area is non-residential space, you will need to follow two paths for the different portions (residential vs. non-residential) of the project. This may seem complicated but is really quite simple. Typically mixed-use buildings have separate parking for the commercial and residential portions of the building. In this case you would designate 5% of the commercial parking spaces as preferred parking. The portion for residents, is exempt from the preferred parking spaces but you will need to implement programs and infrastructure to reduce single-occupancy vehicles. If your parking area is shared between the commercial and residential portions of your building, you will determine the preferred parking spaces based on commercial FTE occupants, and provide 5% preferred parking for that portion of spaces.
