10 rules for unincorporated Dakota County, Minnesota.
Verified from official government sources
Dakota County sets no general quiet-hours ordinance. Minnesota's statewide MPCA noise standard (Minn. R. 7030) applies everywhere, allowing 60 dBA daytime and 50 dBA at night in residential areas; your city enforces it and may add stricter local quiet hours.
Dakota County has no countywide construction-hours ordinance. Minnesota's MPCA daytime noise standard (60 dBA L50, 7 a.m.-10 p.m.) sets the baseline, and each city restricts construction start/stop times, commonly 7 a.m. to allowed evening hours.
Dakota County has no countywide barking-dog ordinance for private property. Barking is treated as a noise nuisance enforced by your city, and Minnesota's dog laws (Minn. Stat. 347.50+) govern dangerous and problem animals.
Dakota County sets no leaf-blower ordinance. Leaf-blower noise falls under Minnesota's MPCA daytime standard (60 dBA L50, 7 a.m.-10 p.m.) and any hour or decibel limits your city chooses to adopt and enforce.
Dakota County regulates amplified sound only in its parks: under Ordinance 107, amplification is allowed just 7 a.m.-10 p.m., may not create a nuisance, and often requires a Special Use Permit. Off park land, amplified music is a city matter under Minn. R. 7030.
Dakota County Ordinance 107, Section 4.2
Amplification of noise/sound is permissible when meeting the following conditions or allowed by Special Use Permit: 1. The sound/noise may not create a nuisance; 2. The sound/noise occurs between 7:00 am-10:00 pm; and 3. The sound/noise is amplified.
Aircraft noise is regulated by the FAA and, in the Twin Cities, the Metropolitan Airports Commission, not by Dakota County. Minnesota's MPCA noise rule exempts most aircraft-in-flight noise, so neither the county nor cities set aircraft noise limits.
Industrial noise in Dakota County is governed by Minnesota's MPCA standard (Minn. R. 7030), which caps noise received at residential property at 60 dBA daytime and 50 dBA at night. The county sets no separate industrial-noise ordinance; cities and the MPCA enforce.
Dakota County uses Minnesota's statewide MPCA decibel standard (Minn. R. 7030). In residential areas the L50 limit is 60 dBA daytime and 50 dBA at night, with L10 limits of 65 and 55 dBA. The county sets no separate decibel ordinance.
Minn. R. 7030.0040

In Dakota County parks, outdoor amplified music is limited to 7 a.m.-10 p.m. and may not create a nuisance under Ordinance 107, often needing a permit. On private property, outdoor music is a city matter under Minnesota's MPCA noise standard.
Dakota County Ordinance 107, Section 4.2
Willfully make or continue, or cause to be made or continued, any loud, unnecessary, or unusual noise which disturbs the peace and quiet within any park or which interferes with use of the park by others or disturbs the residents of adjacent properties.
Dakota County restricts vehicle noise inside its parks: Ordinance 107 bans operating any vehicle that emits excessive or unusual noise. On public roads, vehicle noise and muffler rules come from Minnesota state law and city enforcement, not a county ordinance.
