A structure which does not comply with all applicable regulations of the district in which it is located, but which did comply with all applicable regulations prior to the adoption of these Bylaws, or any subsequent amendments thereto, may be maintained and repaired. Such structure may also be enlarged in any manner which does not increase the degree of noncompliance, for example, such an enlargement must be in a direction where at least the minimum required setback would remain.

6.5 Nonconforming Structures - Proposed Language
Nonconforming structures (see Definitions, section 8) may be maintained and repaired.

Nonconforming structures may be enlarged horizontally in any manner such that the resulting footprint complies with the current setback requirements of the zoning district in which the nonconforming structure is located.

Nonconforming structures may be enlarged vertically, so long as the vertical enlargement does not exceed the current height limitations stated in section 6.12 of these bylaws and the enlargement is made within the existing footprint of the nonconforming structure.
