Sign permit required. Except as otherwise provided
herein, it shall be unlawful for any person to erect, construct, enlarge,
move or convert any sign in the Town, or cause the same to be done,
without first obtaining a sign permit for each such sign. These directives
shall not be construed to require any permit for a change of copy
of any sign, provided that the person, place, establishment, business
or service identified remains the same, nor for the repainting, cleaning
and the normal maintenance or repair of a sign or sign structure for
which a permit has previously been issued under this article, so long
as the sign or sign structure is not modified in any way.
