Nicollet County, Minnesota Building Permit Guide

Outside its six cities, Nicollet County regulates building through zoning permits issued by Property Services at the Government Center in St. Peter. Owners fill in the county’s PDF application for a new dwelling, addition, accessory structure or land alteration and email it in. A house is charged 25 cents per square foot of footprint ($50 minimum) under the 2026 fee schedule, and the county issues no building-code permits of its own.

What requires a permit in Nicollet County?

Section 507.1 of the Nicollet County Zoning Ordinance spells out when a zoning permit is required, and the list is broader than buildings alone. It applies everywhere in the county outside incorporated cities.

The floodplain is treated far more tightly. Inside the Floodplain district, which covers the mapped 100-year and 500-year flood areas, the ordinance requires a zoning permit before any building work including maintenance and repair, before a fence, pool or deck, before fill, riprap or a septic system, and even before storing materials. The county’s fact sheet sums the district up in one line: no development in this district.

What the county decides and what the state holds

Property Services decides uses, lot sizes, setbacks, septic compliance and land alteration under the zoning, shoreland and subdivision ordinances; the ordinance itself warns that a zoning permit does not imply compliance with other county or agency rules. The county’s pages describe no State Building Code plan review or building inspection program in the townships. Electrical permits come from the Department of Labor and Industry, and wells are the Minnesota Department of Health’s.

Nicollet County building department: who handles permitting

Property Services handles land use planning, zoning permits, septic systems, feedlots, wetlands and solid waste, and asks that every document be submitted to its office email, niccopermitapps@co.nicollet.mn.us. Staff recommend calling for an appointment before visiting so the right person is available. County zoning has existed since a 1964 County Board resolution created the Planning and Zoning Advisory Commission.

Cities in Nicollet County

The zoning ordinance stops at city limits, so each city runs its own zoning and makes its own building-code decision; the county’s planning page links the city codes or ordinance pages of North Mankato, St. Peter, Mankato, Nicollet, Lafayette and Courtland. Flood-program status comes from FEMA’s Community Status Book.

Nicollet County permit types

The county posts four fillable zoning permit applications (new dwelling, dwelling addition, accessory structure and land alteration) with site plan examples, a setback fact sheet, a zoning brochure, the driveway permit and a field-entrance conversion application. Every structure application needs a site plan.

Residential permits

A house permit is issued only after the county has an approved septic design, the location of an alternate septic site, an access permit from the road authority, a full set of floor plans with square footage and the general contractor’s license number; the 911 address is assigned after the permit issues. A detached garage or shed may not exceed the ground-floor area or the height of the house and may not sit closer to the front line than the house. In the Agricultural Preservation district the minimum lot is 3½ acres with 2 buildable acres and one new dwelling per quarter-quarter on lots recorded after July 31, 1981; Urban-Rural Residential lots are 1½ acres. In every district buildings keep 30 feet from a bluff line, 100 feet from a ditch and 75 feet from a wetland, and a septic system stays 100 feet from a well less than 50 feet deep.

Commercial and other permits

Commercial structures, including utility cabinets and power stations, pay by the square foot; towers, wind turbines and solar energy systems have flat fees; cannabis businesses register with the county. Conditional use permits go through the Planning and Zoning Advisory Commission, which also hears rezonings and ordinance amendments, while variances and appeals go to the Board of Adjustment and Appeals. Hunting shacks need a conditional use permit and may not exceed 728 square feet or 14 feet in height. A feedlot of 10 animal units or more needs a county feedlot permit under the county’s agreement with the Minnesota Pollution Control Agency, and growth to 300 or more animal units takes a conditional use permit.

What comes before the permit

• Septic design. A licensed designer sizes the system from soil borings under Minnesota Rules 7080–7081, and the county must approve it before a house permit.
• Compliance inspection. Any zoning permit triggers a septic compliance inspection when the lot is in shoreland, is substandard or nonconforming, has no county septic record, or has a system installed more than 20 years ago.
• Access. Driveways need a permit from the road authority, at least 10 feet wide, 14 feet of surface if longer than 200 feet, and a 20-foot flat grade at the road.
• Wetlands. Property Services administers the Wetland Conservation Act outside North Mankato and Courtland.
• Shoreland. The Shoreland district needs 10 acres, 200 feet of lot width and a 200-foot setback from the ordinary high water level.
• Existing violations. A zoning permit is denied until any violation on the property is fixed, except a permit to repair a failing septic system.

Nicollet County permit fees

Property Services charges under its 2026 Fee Schedule brochure, updated January 8, 2026. The county calls it a reference, with the actual fee set by the circumstances of each request.

Worked example from the schedule: a house with a 1,600-square-foot footprint pays 1,600 × $0.25 = $400, and a Type I septic system adds $250, for $650; a 1,200-square-foot detached garage is 1,200 × $0.05 = $60.

Trade permits and who may pull them

Nicollet County issues no electrical, plumbing or mechanical permits. Electrical permits are filed with the Department of Labor and Industry, which shows in its directory whether a city inspects locally. The county’s permit form still asks for the general, electrical, heating, plumbing and septic contractors, whose licenses are state licenses.

• Septic installers. The approved design is installed under the zoning permit by a licensed installer, and county staff inspect it; abandonments are reported on the MPCA form within 30 days.
• Wells. The county’s pages describe no county well permit; its recorder page sends well disclosure questions to the Minnesota Department of Health at 651-201-4600.
• Road work. Public Works issues driveway, field-entrance conversion, moving, special event and utility permits, and handles culvert orders.

How to apply for a Nicollet County permit

Review, corrections and what causes delay

The Board of Adjustment and Appeals meets at 7 p.m. on the third Monday of the month in the Government Center board room, and the Planning and Zoning Advisory Commission usually follows it the same evening; dates shift for holidays and with the number of requests, and several 2026 dates were posted as no meeting. Conditional uses go on to the County Board, while variance decisions are final unless appealed to district court within 30 days. A special hearing at the applicant’s request costs $1,000. Septic designs, a missing compliance inspection on a shoreland or nonconforming lot, and unresolved violations are the usual holds.

Inspections in Nicollet County

County personnel inspect each septic installation against its approved design. A property sale needs a compliance inspection by a state-licensed inspector before closing, and the seller must give the buyer the signed MPCA compliance form; if the county does not receive it within 30 days of recording, the buyer must bring the system into compliance within 10 months.

An owner who adds a bedroom gets one year from the zoning permit to upgrade an undersized system, provided it is not an imminent threat to public health. Zoning staff review permits for setbacks and use, and the county’s pages describe no building-code inspections; electrical work is inspected under the state permit.

Feedlots of 300 or more animal units with liquid manure must inject it as a permit condition, and new feedlots are kept out of the floodplain and shoreland districts.

Minnesota building code

Nicollet County administers its zoning ordinance (with the septic standards built in), shoreland, subdivision, renewable energy, cannabis, adult use, historic preservation and Enhanced 911 ordinances. FEMA’s Community Status Book lists the county as participating in the National Flood Insurance Program since October 16, 1984, with a current flood map dated October 13, 2022; revised preliminary flood maps include accreditation of the Minnesota River levee at North Mankato.

Minnesota has one State Building Code that applies statewide and overrides local building codes, but enforcement is local: whether a building permit is needed depends on whether the city, township or county enforces the code there. Electrical permits come from the Department of Labor and Industry unless the local government runs its own electrical inspection. Minnesota rules
