Outdoor storage of any kind or nature, except storage of those items customarily used in conjunction with a residential occupancy, is prohibited in all Residential Zones.

In all Nonresidential Zones, outdoor storage is only permitted in the side and rear yards as herein regulated. No article, equipment, vehicle, supplies or materials shall be kept, stored or displayed outside the confines of any building unless and until the same is screened by special planting or fencing, as approved by the Planning Board, and maintained in good condition, so that it shall not be visible from any adjacent property or public street, provided, however:

Where otherwise permitted by this chapter, the display, condition for retail sales, of new and used motor vehicles as a permitted accessory use in the Nonresidential Zone District shall not be required to be screened by a planting or fence.
