St. Louis County runs from Duluth to the Canadian border and is the largest county by area east of the Mississippi. Its permitting vocabulary is different from the rest of the state, and so is its geography: the county is big enough to need two permit counters sixty miles apart.
Planning and Zoning administers the land use and onsite wastewater ordinances and their permitting services, together with driveways, addressing and aquatic invasive species management, for the county-administered parts of the unincorporated county.
This guide covers unincorporated St. Louis County. Duluth and the other incorporated cities permit separately, and several townships run their own planning and zoning, so the parcel rather than the postal address determines which authority applies.
The permit has a different name here. The county issues land use permits, and its own worksheet states that they are required for most building construction activities as well as for a variety of other uses. The application categories reflect the region rather than the suburbs: alongside dwellings the form lists cabins, mobile homes and hunting shacks as named permit types.
What requires a building permit in St. Louis County?
Minnesota runs one building code and only one. The Minnesota State Building Code is the standard that applies statewide to the construction, reconstruction, alteration, repair and use of buildings, and it supersedes the building code of any municipality. A city administers and enforces it; it does not get to rewrite it. That makes St. Louis County far more predictable than a jurisdiction in a local-option state — the edition, the exemptions and the technical provisions are the same ones in force across Minnesota.
Typically permit required
- New buildings, additions, alterations and change of occupancy or use
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work, performed by a state-licensed electrical contractor
- Plumbing work, performed by a state-licensed plumbing contractor
- Mechanical and fuel gas work, and anything touching the state energy provisions
- Re-roofing, demolition, egress window openings and signs above the local threshold
Often exempt
- Ordinary repairs and maintenance replacing materials in kind
- Small accessory structures below the local threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Most agricultural buildings, which sit outside the code entirely
An exemption from a building permit is never an exemption from zoning, from the state energy provisions or from a trade permit. Confirm scope with St. Louis County Planning and Zoning before work starts.
Your builder, electrician and plumber are all licensed by the state. The Department of Labor and Industry licenses residential building contractors, remodelers, roofers, electricians and plumbers for the whole of Minnesota, so those credentials travel between cities. A residential building contractor or remodeler licence is required of anyone contracting directly with a homeowner for work totalling more than fifteen thousand dollars in a calendar year. The licence attaches to the business, with a named qualifying person holding the competence, and every licensee contributes to the Contractor Recovery Fund — a pooled indemnity fund that stands in place of a traditional surety bond.
What is actually local, and what is not
Local government decides fees, submittal formats, counter hours, inspection scheduling, zoning and land use — and nothing about the technical code. A municipality must not require building code provisions different from the state code, whether by ordinance or through a development agreement. The single exception is an ordinance that is more restrictive, justified by geological conditions, and approved by the state building official. Separately, agricultural buildings sit outside the code almost entirely, and a city that requires exterior work to be finished within a set period cannot demand completion earlier than a hundred and eighty days after the permit issues. The county is large enough that it operates two permit offices — one in Duluth at the Government Services Center and one in Virginia at the Northland Office Center, roughly sixty miles apart — and the county does not administer everywhere within its own boundary, since some townships run their own planning and zoning and the county publishes a separate township and city zoning administration reference for exactly that reason
Who handles permitting in St. Louis County?
Planning and Zoning administers the county land use and onsite wastewater ordinances, issuing land use permits, conditional use permits, variances, land alteration permits and subdivision approvals across the county-administered parts of the unincorporated county.
| Detail | Information |
|---|---|
| Department | St. Louis County Planning and Community Development |
| Duluth office | Government Services Center, 320 West Second Street, Duluth, MN 55802 |
| Virginia office | Northland Office Center, 307 South First Street, Virginia, MN 55792 |
| Phone | (218) 725-5000 Duluth; (218) 749-7103 Virginia |
| Permit type | Land use permit, required for most building construction activities |
| Zoning | Ordinance 62; subdivision under Ordinance 60 |
| Land alteration | Required for filling, grading or excavating on or near shoreland |
| Incomplete applications | Returned rather than processed |
Several approvals sit alongside the land use permit rather than inside it. A land alteration permit is needed for filling, grading or excavating on or near shoreland property; conditional use permits are required for most commercial and industrial uses, outdoor signs, planned developments and certain short term rental uses; and a borrow pit excavating material for use as fill elsewhere needs a permit whenever the material is for sale.
Applications are checked before they are accepted rather than after. Incomplete applications are returned, applicants may be required to submit further property descriptions, surveys, site plans and building plans before an application is accepted or approved, and a certificate of compliance approval or municipal or sanitary district approval may be required as part of the submission.
Permit types
Residential permits
Residential applicants should first establish whether the parcel sits in a county-administered area or in a township that runs its own zoning, since the county publishes that split separately. Licensed contractors and homeowners both complete and submit the application forms, and the fee schedule should be checked before applying online so the correct permit is selected.
How Minnesota contractor licensing works
Minnesota licenses the trades centrally, which removes the city-by-city credential problem entirely. The Department of Labor and Industry licenses residential building contractors and remodelers, residential roofers, electricians and plumbers, and those licences are valid across the state. The licence is issued to the business entity, with a named qualifying person who must pass a written examination and be an owner, officer, member, partner, chief manager or actively engaged managing employee.
A pooled fund instead of a bond. Rather than requiring each contractor to post a surety bond, Minnesota operates the Contractor Recovery Fund, which every licensee pays into and from which homeowners may be compensated. An unpaid judgment against the fund bars further licensure until it is reimbursed. Note also that a contractor providing services in more than one special skill area must be licensed, while a specialty contractor providing only one special skill generally need not be — except residential roofers, who must be licensed regardless.
Commercial permits
Commercial and industrial uses generally require a conditional use permit in addition to the land use permit, and communication towers and utility structures are allowed in all zone districts on lots or leased parcels of at least twenty thousand square feet. Subdivision of land outside cities is regulated by the county subdivision ordinance.
Mechanical work, and where the state reviews plumbing directly
Mechanical and heating contractors are the exception to statewide licensing: there is no state mechanical contractor licence, but a contractor must file a twenty-five thousand dollar bond with the department to contract for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work. On the plumbing side the state reviews plans directly for public and commercial buildings and for residential buildings of five or more units, unless the municipality holds a plan review agreement with the department — around seventy cities do.
St. Louis County permit costs and fees
St. Louis County publishes a land use permit fee schedule and asks applicants to review it before applying so that the correct permit type is selected. Cheques are made payable to the county auditor rather than the department.
| Fee component | How it works |
|---|---|
| Building permit | Set locally on valuation; the code is statewide but the fee schedule is not |
| Plan review | A percentage of the permit fee or a flat charge, set locally |
| State surcharge | A statutory surcharge collected with the permit and remitted to the state |
| Electrical | Permitted and inspected through the state electrical programme or the municipality |
| Plumbing | State plan review where it applies; otherwise local, under any plan review agreement |
| Energy compliance | Documentation against the state energy provisions, which are not locally variable |
Because the technical code is identical statewide, fee differences between Minnesota cities are differences of policy rather than of requirement — two cities enforcing the same provisions can price the same project very differently. Ask St. Louis County Planning and Zoning for the schedule in force on your filing date, and confirm whether the state or the city holds the plumbing and electrical route for your scope.

Trade permits and who may pull them
Minnesota separates the credential from the permit. The licence to do the work is issued by the state and is valid everywhere; the permit for a particular job is issued locally, or by the state where it holds the administrative authority for that scope.
Your builder, electrician and plumber are all licensed by the state. The Department of Labor and Industry licenses residential building contractors, remodelers, roofers, electricians and plumbers for the whole of Minnesota, so those credentials travel between cities. A residential building contractor or remodeler licence is required of anyone contracting directly with a homeowner for work totalling more than fifteen thousand dollars in a calendar year. The licence attaches to the business, with a named qualifying person holding the competence, and every licensee contributes to the Contractor Recovery Fund — a pooled indemnity fund that stands in place of a traditional surety bond.
- Electrical work must be performed by a state-licensed electrical contractor. An owner-occupant of a single family dwelling may do their own work, but not work involving the electrical service equipment.
- Plumbing work must be performed by a state-licensed plumbing contractor, or by the owner-occupant of a single family dwelling on that dwelling.
- Mechanical work needs no state licence but does need the bonded contractor described above.
Permit required
- Service installations, panel upgrades, new circuits, solar photovoltaic and EV charging
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- Mechanical installation and change-out, ductwork and venting
- Any work in a public building or a residential building of five or more units, which may trigger state plan review
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection
How to apply for a St. Louis County building permit
Some townships run their own planning and zoning rather than the county.
That is the instrument here, and it covers most building construction activities.
Duluth and Virginia both take applications, and they are about sixty miles apart.
Filling, grading or excavating on or near shoreland needs its own permit.
Most commercial and industrial uses, signs, planned developments and some short term rentals need one.
Incomplete applications are returned rather than held.
Review, corrections and what actually causes delay
Because the technical code does not vary, most delay in Minnesota is procedural rather than substantive. The common causes are submitting to the wrong authority for plumbing where the state holds plan review; assuming a neighbouring city’s exemption list applies when the difference was only ever a local administrative practice; missing the state energy compliance documentation; and treating a structure as agricultural when it does not meet the statutory definition. Confirm the checklist with St. Louis County Planning and Zoning before filing.
Watch the completion clock as well as the permit clock. A Minnesota municipality may adopt an ordinance requiring exterior work authorised by a building permit to be completed within a set period, but it cannot require completion earlier than a hundred and eighty days after the permit is issued. Confirm whether St. Louis County has adopted such a control and what period it uses.
Inspections in St. Louis County
Standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy compliance, fire systems on commercial work, and final, with a certificate of occupancy before the building is used. Because the county instrument is a land use permit, confirm separately who carries out any building code inspection for the parcel rather than assuming the county does.
Where the state holds the administrative authority for plumbing — on public buildings, state-licensed facilities, school district and charter school projects and certain others — inspections are carried out by state plumbing inspectors rather than municipal staff, and the permit and inspection fees are submitted to the state. Where a municipality holds a plan review agreement and its inspectors are licensed master or journeyworker plumbers, the municipality inspects instead.
Do not cover work before the required inspection has been approved. Keep the issued permits, the approved plans and the energy compliance documentation available on site.
St. Louis County permit search and official resources
St. Louis County Planning and Zoning holds the building permit record for unincorporated St. Louis County. Where the state carried out plumbing plan review or inspection, that record sits with the department instead, so a full history on a commercial building or a larger residential one may need both.
Two questions, not three. In a local-option state you would have to establish which code a jurisdiction adopted. In Minnesota you do not — the code is the same everywhere. What you do need to establish is who holds the plumbing and electrical route for your scope, and what this particular city requires procedurally at the counter.

Frequently asked questions
Why is it called a land use permit?
Because that is the county instrument. Planning and Zoning administers land use and onsite wastewater ordinances, and its worksheet states that land use permits are required for most building construction activities as well as for a variety of other uses.
Which office do I use?
Either. The county runs permit offices in Duluth at the Government Services Center and in Virginia at the Northland Office Center, roughly sixty miles apart, both taking planning and zoning enquiries.
Does the county cover the whole county?
No. Some townships administer their own planning and zoning, and the county publishes a separate reference for township and city zoning administration, so the parcel needs checking before applying.
Is the building code different up here?
No. Minnesota runs one building code and only one. The Minnesota State Building Code is the standard that applies statewide, and it supersedes the building code of any municipality. A city administers and enforces it but must not, by ordinance or through a development agreement, require building code provisions regulating components or systems of any structure that differ from the state code. The single exception is an ordinance that is more restrictive, justified by geological conditions, and approved by the state building official. That is why an edition question in Minnesota has one answer rather than one per city.
Who licenses my contractor?
The state. Contractor credentials in Minnesota are held by the state. The Department of Labor and Industry licenses residential building contractors, remodelers, roofers, electricians and plumbers for the whole state, so a licence travels between jurisdictions. A residential building contractor or remodeler licence is required of anyone contracting directly with a homeowner for more than fifteen thousand dollars of residential work in a calendar year. The licence attaches to the business with a named qualifying person holding the competence, and every licensee contributes to the Contractor Recovery Fund rather than posting a surety bond. Specialty contractors offering only one special skill generally need no state licence, except residential roofers, who always do.
What else might I need?
A land alteration permit for filling, grading or excavating on or near shoreland; a conditional use permit for most commercial and industrial uses, outdoor signs, planned developments and certain short term rentals; and subdivision approval where land outside a city is being divided.
