Sec. 6. - Nonconforming uses and buildings.
a. Continuance. A lawful nonconforming use existing at the effective date of this ordinance may be continued, except as hereafter provided, although such use does not conform with the provisions of this ordinance.
b. Extension and alteration. A lawful nonconforming use shall not be extended or structurally altered.
