Summary

Dane County bans excessive noise from motor vehicles, radios and other mechanical devices countywide under ch. 34.04, wherever a person's stereo, muffler or engine noise unreasonably disturbs the peace, comfort or repose of neighbors. Violators face a $25 to $100 forfeiture per offense under the ch. 34.99 penalty schedule.

City-specific rules exist: Madison, Fitchburg, Sun Prairie, and Middleton have their own vehicle noise rules that differ from Dane County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

34.04 PROHIBITION OF EXCESSIVE NOISE DISTURBING THE PUBLIC PEACE. (1) Excessive noise defined. Excessive noise, as used in this section, shall mean any sound or level of sound of sufficient loudness that it tends unreasonably to disturb the peace, comfort, quiet or repose of persons in the vicinity of the noise including, but not limited to, any such noise produced in the operation or use of any radio, phonograph, tape or disc player, television or other mechanical or electrical device, machine or motor vehicle. (2) No person shall cause or participate in the production of any excessive noise... (3) This section shall apply in all areas of Dane County except in those municipalities which have an ordinance on the same subject matter.

Full Breakdown

04(1) of the Dane County Code defines "excessive noise" broadly to include "any such noise produced in the operation or use of any radio, phonograph, tape or disc player, television or other mechanical or electrical device, machine or motor vehicle" that tends to unreasonably disturb the peace, comfort, quiet or repose of persons nearby. Subsection (2) makes it unlawful for any person, or any property owner, user or occupier, to "cause, suffer, permit or participate in" producing that noise. The rule reaches booming car stereos, modified mufflers and unnecessary engine revving equally.

Subsection (3) limits the ordinance's reach: it applies in all areas of Dane County except municipalities (cities and villages such as Madison, Fitchburg or Middleton) that already have their own noise ordinance on the same subject, so incorporated areas fall back to their own municipal code instead. Subsection (4) carves out noise necessary for safety or property preservation, noise otherwise required by law, noise from an activity already regulated by other law, and noise from agricultural activity, a protection relevant to the county's many farms.

The Dane County Sheriff's Office enforces the section in the unincorporated towns and any covered municipality. A citation is a forfeiture (civil, not criminal) matter heard in county circuit court unless resolved by paying the listed amount, and each separate incident of excessive noise can be charged as its own violation.

Violations & Fines

Violating ch. 34.04 is a forfeiture-only offense under the ch. 34.99(2) penalty schedule, which sets the fine for a 34.04 violation at not less than $25 nor more than $100 per offense, plus court costs and prosecution costs under ch. 34.99(1). Nonpayment can escalate to enforcement through Dane County Circuit Court; the general ch. 34.99(1) confinement provision caps jail time for chapter 34 offenses generally at 30 days in default of payment.

Frequently Asked Questions

Does this noise rule apply inside Madison?
No. Section 34.04(3) states the ordinance applies everywhere in Dane County "except in those municipalities which have an ordinance on the same subject matter," and Madison, Fitchburg, Middleton and similar cities/villages have their own noise codes, so residents there are governed by municipal law instead.
What counts as excessive vehicle noise under ch. 34.04?
Section 34.04(1) defines it as any sound "of sufficient loudness that it tends unreasonably to disturb the peace, comfort, quiet or repose of persons in the vicinity," expressly listing motor vehicles alongside radios and other electronic devices as covered sources.
How much is the fine for a first violation?
The ch. 34.99(2) penalty schedule lists a $25 to $100 forfeiture specifically for section 34.04, in addition to court costs and prosecution costs assessed under ch. 34.99(1).
Is farm equipment noise exempt?
Yes. Section 34.04(4)(d) states the ordinance does not prohibit noise "produced as a result of any agricultural activity," recognizing the county's rural towns rely heavily on farm operations.
