All construction in or contiguous to residential neighborhoods shall be carried on between the hours of six o'clock (6:00) A.M. and ten o'clock (10:00) P.M., from Memorial Day to Labor Day and the rest of the year from seven o'clock (7:00) A.M. and nine o'clock (9:00) P.M., except as otherwise specified elsewhere in this code. The city building official may authorize operations at other hours only: a) if it is shown that restricting the hours of operation would unduly interfere with the development of the property; b) there is a need to do such operations at other times due to such factors as weather or availability of labor or building materials; or c) if it is shown that the neighboring properties would not be adversely affected. (Ord. 429 §1, 1994)
