Full Breakdown

15 requires a permit before operating any outdoor sound system, projecting amplified music or a live performance outdoors, projecting sound outside a building, or projecting amplified sound from a vehicle anywhere in the City. Exemptions cover car stereos, typical household radios, televisions or stereos used on residential premises, equipment run by police, fire or emergency agencies, equipment used by the Middleton-Cross Plains School District or nonprofits for athletic-event announcements or class bells, and church equipment simulating bells to signal services. Applications go to the City Clerk, must be signed by the applicant and by whoever controls the premises if different, both over eighteen, and come with a nonrefundable fee under the Fee Schedule, waived for City-run events.

Requests involving City property are routed to the Public Lands Manager for comment, and the Clerk can attach conditions to protect public health, peace, safety and welfare. m. Denials or added conditions can be appealed to the License and Ordinance Committee and then the Common Council, and the underlying decibel limits themselves can only be waived by the Common Council after hearing that Committee's recommendation. Permits can be suspended or revoked for violating conditions, with a hearing before the License and Ordinance Committee on ten days' notice.

Violations & Fines

Violating Section 7.15 or a permit condition draws a forfeiture of at least one hundred dollars. An officer who finds a sound system running in violation may order the volume turned down to a compliant level or the system shut off; disobeying that order is a separate violation and can lead to confiscation of the equipment. Police can also order immediate cessation of permitted sound that becomes an unabatable public nuisance.

Frequently Asked Questions

Do I need a permit to play music at a backyard party in Middleton?
Only if you're using an amplified sound system outdoors. Typical household radios, TVs, stereos or boom-boxes used on residential premises are exempt from the § 7.15 permit requirement, though the noise can still be cited as a public nuisance under other City ordinances if neighbors complain.
How loud can amplified sound be under a Middleton permit?
Sunday through Thursday, § 7.15 caps amplified sound at 65 decibels at the lot line from 9 a.m. to 9 p.m., dropping to 60 decibels until midnight. Friday and Saturday, and holidays, the louder 65-decibel window extends to 11 p.m. before dropping to 60. No permit is issued for midnight to 9 a.m.
What happens if I ignore a police order to turn down amplified sound?
Refusing an officer's order to lower the volume or shut off the system is itself a violation of § 7.15 and can lead to the Police Department confiscating the sound equipment, on top of the forfeiture of at least $100 for the underlying violation.
Who issues the amplified sound permit and how much does it cost?
The City Clerk issues permits under § 7.15 upon a signed application accompanied by a nonrefundable fee set in the Fee Schedule under Municipal Code § 3.12. Requests on City property are also routed to the Public Lands Manager for comment before approval.
