Building permits in Unincorporated Washington County

Unincorporated Washington County does not issue residential building permits. Washington County does not issue building permits. Every township in the county enforces the State Building Code itself per the DLI directory (https://workplace.doli.state.mn.us/jurisdiction/, search county Washington): Baytown, Denmark, Grey Cloud Island, May, Stillwater and West Lakeland townships each have their own building official. The county Public Works Department issues zoning permits in the townships under its Development Code.

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 Washington 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.
