Sec. 30-1. “Sound nuisance shall mean any sound which either exceeds the maximum permitted sound levels specified in section 30-2, or for purposes of sections 30-4 and 30-6, otherwise unreasonably disturbs, injures or endangers the comfort, repose, health, peace or safety of others within the limits of the city.”

Sec. 30-10. Penalty.

“Any person who violates any provision of this chapter is guilty of a misdemeanor and, upon conviction, shall be subject to a fine of not less than fifty dollars ($50.00) nor more than one thousand dollars ($1,000.00). Upon a second or subsequent conviction for a violation of this chapter within a twelve-month period, said person shall be fined not less than $100.00 nor more than $2,000.00. Each day that any violation continues shall constitute a separate offense. To the extent that any conduct prohibited under this chapter also constitutes an offense under state law, then it shall be punishable as provided by state law.”

Sec. 30-7. Defenses.

“The following defenses shall apply to any offense established in this chapter:

(1) The emission of any sound was for the purpose of alerting persons to the existence of an emergency, danger or attempted crime.”

The random and intermittent alarm sounding even when construction workers are present negates this defense.
