Do I need a permit for window or exterior door replacement in Unincorporated Hennepin County?
Unincorporated Hennepin County does not issue residential building permits. Hennepin County has no county building permit program. All of the county is inside cities (which issue their own permits) except the Fort Snelling unorganized territory (federal and state land including MSP Airport), which the Minnesota Department of Labor and Industry jurisdiction directory (https://workplace.doli.state.mn.us/jurisdiction/, search by county) lists as T28-R23 and T28-R24 with 'HAS ADOPTED THE BUILDING CODE: NO'. The only other non-city record in the directory, Independence, lists its own building official.
The requirements below come from Minnesota rules and describe the standard the work must still meet. They are not a statement that Unincorporated Hennepin County will issue you a permit.
Most likely yes. Window or exterior door replacement usually requires a permit in Minnesota. Confirm the specifics with Unincorporated Hennepin County.
Window and door replacement is not listed as exempt work in Minn. R. 1300.0120, subp. 4, so enforcing jurisdictions commonly require a permit; how a like-for-like swap is treated varies, so confirm locally. Windows in sleeping rooms and basements must meet the emergency escape and rescue opening rules of the Minnesota Residential Code (Minn. R. 1309.0310), and new fenestration must meet the Minnesota Residential Energy Code (Minn. R. ch. 1322). Whether a building permit is issued at all depends on whether the city, township, or county covering the address has adopted and enforces the State Building Code (Minn. Stat. 326B.121); check the DLI local code lookup first. Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule.
