Building permits in Unincorporated Dakota County

Unincorporated Dakota County does not issue residential building permits. Dakota County does not issue building permits. All 12 townships have adopted the State Building Code and each issues permits through its own designated building official (for example Castle Rock, Eureka, Marshan, Nininger: Mark Luostari, 651-322-6626; Douglas and Waterford: Karl Horning, 952-442-7520, per DLI).

That does not make the work unregulated. The construction standard still applies, trade licensing still applies, and separate approvals such as on-site sewage, floodplain development, and driveway access are handled by other offices. Below are the contact details for the office to ask, plus guides for the projects homeowners ask about most.

Minnesota has one State Building Code (Minn. Stat. 326B.121), which for homes is the Minnesota Residential Code based on the 2018 IRC, and it is the legal construction standard everywhere in the state. Building permits, however, are issued only where the city, township, or county covering Unincorporated Dakota County has adopted the code by ordinance; the seven-county metro area and communities that had adopted it by 2008 must keep enforcing it, while many small outstate towns and townships have no building permit program. Electrical work is different: it needs a state electrical permit from the Department of Labor and Industry everywhere except in the cities that run their own electrical inspection program. Minnesota's state permit rule exempts some small work, such as sheds up to 200 square feet and fences up to seven feet, but there is no statewide dollar-value exemption. Confirm with the building office that has jurisdiction over Unincorporated Dakota County before starting work.

Permit FAQs for Unincorporated Dakota County

Do I need a building permit in Unincorporated Dakota County?
Dakota County does not issue building permits. All 12 townships have adopted the State Building Code and each issues permits through its own designated building official (for example Castle Rock, Eureka, Marshan, Nininger: Mark Luostari, 651-322-6626; Douglas and Waterford: Karl Horning, 952-442-7520, per DLI).
Who issues building permits in Unincorporated Dakota County?
Nobody does. Unincorporated Dakota County does not run a residential building permit program, which is why this page lists the Unincorporated Dakota County building department as the office to contact rather than as a permit issuer. Your mailing city is not always the authority over your property, so confirm which jurisdiction you are actually in before assuming this applies to you.
What still applies in Unincorporated Dakota County if there is no building permit?
The construction standard does. Work must still meet the Minnesota Residential Code (Minn. R. ch. 1309, 2018 IRC-based), and trade licensing rules apply regardless of whether a permit is issued. Separate approvals such as on-site sewage, floodplain development, and driveway access to a public road are handled by other offices and are unaffected. Ask the Unincorporated Dakota County building department which of those reach your property before you start.
