Pennington County, Minnesota Building Permit Guide

In rural Pennington County the permits that matter most are shoreland, floodplain and septic permits, which the county runs through the Pennington Soil and Water Conservation District (SWCD) at 201 Sherwood Avenue South in Thief River Falls. A shoreland building permit application costs $25 and needs a compliant septic system first, and a homeowner septic permit costs $100, or $25 after watching the SWCD’s septic video. Five townships add their own permits, and the three cities handle permitting inside their limits.

What requires a permit in Pennington County?

The county’s permit rules that the official pages describe come from two ordinances administered by the SWCD: the Pennington County Shoreland Ordinance and the county’s individual sewage treatment system ordinance. Shoreland means any land within 300 feet of a stream or river, or 1,000 feet of a lake, pond or flowage, whether or not the parcel touches the water.

The SWCD’s pages describe no county building or zoning permit for land away from shoreland. Instead, the shoreland form tells applicants to check with the township for other requirements, and the SWCD names five townships, Rocksbury, North, Norden, Sanders and Numedal, where the township clerk should be asked about further permits.

What the county decides and what the state holds

The county’s permits set where a building and its septic system may go: setbacks from the water, bluffs and roads, flood elevation and treatment standards. The shoreland application asks the applicant to certify that the work will conform to the county ordinances and the Minnesota building codes, but none of the county’s pages describe plan review or construction inspections, and no county building code ordinance is posted. Electrical permits come from the Minnesota Department of Labor and Industry (DLI).

Pennington County building department: who handles permitting

The Pennington SWCD is the working office for county land use: its staff specialties include shoreland and floodplain, septic systems and the water plan, and a separate specialist runs the feedlot program. Forms can be printed from the SWCD website or picked up from the Water Plan Coordinator. The SWCD is also the local government unit for the Wetland Conservation Act. Road permits come from the County Highway Department.

Cities in Pennington County

Each city decides its own zoning and whether it enforces the State Building Code, and handles permits inside its limits.

Pennington County permit types

A shoreland permit is assembled from several forms. Every project starts with the Shoreland Permit Summary Form, which records the applicant, the legal description and parcel number, the river name and its classification (natural environment, agriculture, urban or tributary) and whether wetlands or lowland areas are involved; the form itself states that it is only an application and that work may not start until a permit is approved.

Residential permits

For a building, add the Shoreland Building Permit Supplemental Form and the Floodplain Form. The supplemental form lists the general, earthwork, electrical and plumbing contractors and any architect, the type of project (new construction, addition, relocation, repair, foundation only, roofing), the structure type and use, construction type, sewage disposal and heating, existing and proposed dimensions, lot dimensions and setbacks, and a sketch plan. It also asks for the cost of the improvements and the estimated value of the existing structure, and works out the improvement as a percentage of that value. For a septic system, the homeowner or installer files a septic permit application and the licensed designer completes a separate designer form.

Commercial and other permits

The building form covers commercial, industrial, public and multi-family uses as well as homes. Projects that cannot meet the ordinance go to the Board of Adjustment as a variance ($300) or need a conditional use permit ($250); the office records whether a file was referred to the township and the board, and whether a public hearing was held. Feedlots are registered online with the state and permitted through the county’s local feedlot program, which the SWCD and the county run together; it covers facilities under 1,000 animal units, or those not needing federal permits, with registration, permits, inspections, education and complaint follow-up.

What comes before the permit

• Septic compliance. The shoreland ordinance requires a compliant septic system before a shoreland permit is issued; the SWCD keeps a list of licensed inspectors.
• Flood elevation. In a floodplain, the regulatory flood protection elevation is the 100-year base flood elevation plus the freeboard the ordinance requires plus any floodway stage increase.
• Wetland determination from the SWCD before any work affecting a wet area, even a wildlife pond. The act aims at no net loss: a wetland may be drained or filled only under an approved application, usually with replacement elsewhere, though some activities need no replacement.
• Township permits in Rocksbury, North, Norden, Sanders and Numedal townships.
• Right of way. Culverts and ditching in a county road right of way through the Highway Department’s online permit site.

Pennington County permit fees

Pennington County’s permit fees are printed on the application forms themselves, which carry no adoption date. The two forms differ for septic systems: the shoreland summary form lists a $25 septic line, while the septic permit application sets $100, reduced to $25 for applicants who watch the septic video on the SWCD website.

Reading the forms together: a new lake home in shoreland pays $25 for the shoreland building permit and, for its new septic system, the $100 septic permit ($25 after the video); the forms do not say whether the summary form’s $25 septic line is charged on top of that, so ask the SWCD before paying. A setback variance adds $300.

The SWCD also offers money for failing systems. Clean Water Fund grants replace systems that discharge sewage to the ground surface or surface water, back up into a dwelling or fail to protect groundwater; owners must meet low-income guidelines and the money goes first come, first served. The other source is Agricultural Best Management Practices loans of up to $200,000 at no more than 3% for up to 10 years, which can also fund septic upgrades.

Trade permits and who may pull them

Neither the county nor the SWCD issues electrical, plumbing or mechanical permits. Electrical permits and inspections in rural Pennington County come from DLI, under the 2026 National Electrical Code for permits filed on or after August 17, 2026, and electricians, plumbers and residential building contractors are licensed by the state. The shoreland building form asks for the names of the electrical and plumbing contractors.

• Septic designers sign the designer form, which requires a site evaluation, a system design, a site sketch and two soil verifications; a lot must have room for two drainfields, and only one trench system is allowed per acre.
• Septic installers or owners must give SWCD staff a copy of the approved design before any excavation starts.
• Well setbacks follow the Minnesota Department of Health rules, and the SWCD runs well sealing and well testing programs.
• Movers and haulers use the Highway Department’s transportation permits for overweight and oversize loads, construction materials and mobile or modular home moves.
• Contractors in wetlands work under the Wetland Conservation Act, which requires at least two acres of replacement for each acre altered where replacement applies.

How to apply for a Pennington County permit

Review, corrections and what causes delay

The summary form warns that most projects need one or more additional forms, plans, specifications and a written project description before the application is complete, so a missing supplement is the most common hold-up. A septic system that has not been found compliant blocks the shoreland permit. Setback shortfalls go to the Board of Adjustment, and the office notes whether the file was referred to the township and whether a hearing notice and public hearing were needed. Septic permits are valid for 12 months from issuance.

Inspections in Pennington County

Septic systems are inspected by a state-licensed inspector before they are covered; a system covered too early must be uncovered on the inspector’s direction. The inspector prepares a certificate of compliance or notice of noncompliance and gives it to the owner and the SWCD within 15 days, and by applying the owner allows the SWCD to inspect before, during and after construction. A standard system needs 3 feet of separation to limiting soil, and the county’s alternative local standard allows 2 feet.

Shoreland building permits are checked against the setbacks printed on the supplemental form: 100 feet from the ordinary high water mark for structures and 10 feet for water-oriented accessory structures, 75, 100 or 150 feet for sewage systems depending on the water’s class, 30 feet from the top of a bluff, 50 feet from a federal, state or county highway right of way and 20 feet from a town road or public street. The county posts no building-code inspections, and wiring is inspected by the state.

Minnesota building code

Pennington County’s land use program, run by the SWCD, covers shoreland, floodplain, septic, wetlands and feedlots. FEMA’s Community Status Book lists the county in the National Flood Insurance Program since May 3, 1990, with a current flood map dated December 1, 2022; St. Hilaire and Thief River Falls also participate, and Goodridge has no listing in the book.

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
