Section 6.12. No Storage: Trash. No lumber, metals, bulk materials, refuse, or trash shall be kept, stored, or allowed to accumulate on any Lot or on the Common Area, except building materials may be stored on a Lot during the course of construction of any approved structure. If trash or other refuse is to be disposed of by being picked up and carried away on a regular and recurring basis, the trash containers shall be promptly returned to their regular storage location out of view from the street after the trash is picked up. The Association may require, but shall not be obligated to require, that the Owner(s) of all Lots use the same trash collection service to reduce the number of days that trash is collected and to maintain the appearance of the neighborhood.
