St. Paul Noise Ordinance: Quiet Hours, Decibel Limits, Penalties

The Saint Paul noise ordinance, found in Chapter 293 of the city’s Legislative Code, sets decibel ceilings that change with the zoning of the property receiving the sound, imposes a quiet period from 10:00 p.m. to 7:00 a.m., and gives the Saint Paul Police Department primary authority to enforce it.¹ Noise can violate the ordinance in two ways: by exceeding a numeric decibel limit, or by being “plainly audible” at certain distances during nighttime hours.

Quiet Hours and the Plainly Audible Rule

Quiet hours run from 10:00 p.m. to 7:00 a.m. every day of the week. Saturdays and Sundays get no later cutoff; 7:00 a.m. applies year-round.¹

During that window, Section 293.07 treats any sound-producing device as a presumptive violation if it is plainly audible at the property line of the building it’s in, in an adjacent hallway or apartment, or 50 feet from the source if the device is outdoors.² “Prima facie” is the ordinance’s word for it, and the practical effect is that the city does not have to prove the noise was unreasonable. Audibility at the stated distance is enough to establish the violation, and the burden shifts to the person making the noise to justify it.

Loud gatherings get their own hook. Under Section 293.02, no one may knowingly remain at a noisy assembly, and no property owner may let a property be used for one.² Police can break up a loud party on that basis without taking a decibel reading.

Decibel Limits by Zoning District

Chapter 293 ties its numeric limits to the zoning of the property where the sound is received, not where it originates. Readings are taken as a one-hour L10 average in A-weighted decibels (dBA).¹

Residential: 65 dBA from 7:00 a.m. to 10:00 p.m., and 55 dBA from 10:00 p.m. to 7:00 a.m.
Commercial: 70 dBA at all times.
Industrial: 80 dBA at all times.

The nighttime drop to 55 dBA in residential zones is the strictest standard in the ordinance, and it stacks with the plainly audible rule. Equipment or music that sits just under 55 dBA at the lot line can still be cited if it carries clearly to a neighbor’s property.

Power Tools, Construction, and Vehicles

Lawn mowers, leaf blowers, chainsaws, snowblowers, and similar domestic power tools are exempt from the decibel limits in Section 293.09, but only between 7:00 a.m. and 10:00 p.m.² Run them before or after that window and they’re treated like any other noise source, which usually means a presumptive violation if the neighbors can hear them.

Construction and demolition work has its own cap: 85 dBA measured 50 feet from the source. When a site sits in or borders a residential district, the equipment must also meet the tighter residential limits at the nearest home.²

Vehicles with modified or missing mufflers, loud stereos, or rattling components fall under the ordinance as well. In most cases an officer has to personally hear the noise before issuing a citation or correction order.¹ A car stereo audible at 50 feet is treated more seriously; a second offense can bring a fine of up to $500. If a neighbor’s car is the problem, you can ask police to inspect it, and they may ask you to sign a formal complaint.

Barking Dogs

Persistent animal noise is handled under Ordinance Section 200.14, not Chapter 293. Owners may not keep a dog that howls, yelps, or barks to the reasonable annoyance of another person.¹ There is no set number of minutes of continuous barking that triggers a violation.

Enforcement needs corroboration. Two witnesses, or one officer plus one witness, must be willing to testify that the violation occurred before the city can issue a citation or impound the animal.¹ A first complaint typically results in a written advisement to the owner; repeated or subsequent complaints can escalate to citations or impoundment.³

What’s Exempt and When You Need a Variance

Several categories of noise sit outside the decibel limits in Section 293.09 regardless of volume:

Emergency signaling devices, such as fire alarms and civil defense sirens.
Emergency vehicles and city snowplows.
Emergency repair work needed to protect public health or safety, or to restore a public service, for 24 hours after the work begins.
Domestic power tools, between 7:00 a.m. and 10:00 p.m.
Parades and one-day festivals.
Neighborhood nonprofit festivals of up to three days running between 7:00 a.m. and 10:00 p.m., provided stationary amplified equipment stays below 90 dBA at 50 feet.

The emergency repair exemption is worth knowing. A middle-of-the-night water main break that brings in heavy equipment is covered for 24 hours, and complaints during that window will not force the work to stop.²

Anything else that will exceed the ordinance’s limits, such as an outdoor concert, a large party with amplified music, or pile-driving on a construction job, requires a sound level variance approved by the Saint Paul City Council.⁴ The Department of Safety and Inspections manages the application, which carries a $175 fee and must be filed at least 60 days before the event.⁵ Property owners within 300 feet are notified and given 15 days to comment before a public hearing.

How to Report a Violation

For noise happening right now, call the Saint Paul Police Department. Police have primary enforcement authority under Section 293.10.² Officers can take decibel readings at the property line or judge whether the sound is plainly audible at the distances the ordinance specifies, and they can issue a citation on the spot if a violation is confirmed.

For a property with a recurring problem, such as a neighbor whose parties run late every weekend or a business that runs equipment at night, the city offers a Problem Properties form through the police department for ongoing tracking.⁶

Penalties

Chapter 293 does not publish a fixed fine schedule for general noise violations. Under Minnesota law, municipal ordinance violations are typically petty misdemeanors with a maximum fine of $300, though specific offenses can carry more. Vehicle stereo violations are the clearest example of a higher ceiling in the Saint Paul code: a second offense can run up to $500.¹ Repeated violations at the same property can also pull in DSI code enforcement beyond the initial police response.
