No off-street parking shall be required for uses accessory to any institutional use specified in § 150-113 or for an accessory restaurant used primarily for students, patients, tenants or employees occupying a principal use.
In the case of accessory retail sales, restaurants
or swimming pools, the lesser parking requirement for either the accessory
use or the principal use, whichever requirement is less, shall be
reduced 50%.
Where places of assembly specified in § 150-114 are located on the same lot with other uses, the Concord Zoning Board of Appeals may permit a reduction in the number of required off-street parking spaces for such places of assembly.
