Barndominium Permits in Minnesota

Barndominium permits in Minnesota start with a question most states never ask: does anyone enforce the building code where your land is? The State Building Code applies to a new home everywhere in Minnesota, but it is enforced only where a city, township or county has adopted it. We find out who has jurisdiction for your parcel, handle the building permit application where there is one, and line up the zoning, shoreland, septic and well approvals that apply whether or not there is.

Who Enforces the Building Code on Your Land

Minnesota's State Building Code is, in the words of the Department of Labor and Industry, the minimum construction standard throughout the state, including all cities, townships and counties, but it is not enforceable by a municipality unless that municipality has adopted it by local ordinance. State law says a municipality that had adopted the code by 1 January 2008 must keep enforcing it, except for municipalities under 2,500 people outside a metropolitan county. Any city, township or county can choose to adopt it, and a county that adopts it covers the townships and unincorporated areas within it.

The result is a patchwork. In one township a building official reviews your plans and inspects every stage; in the next, there may be no building permit for a house at all. The Department of Labor and Industry publishes a jurisdiction lookup that shows, for a city or township and county, whether the code has been adopted and who administers it. We check it for every parcel, and we confirm with the local office, because the answer decides the whole permit path.

Where nobody enforces the code, the code still applies, and we build to it. What changes is that no local building official reviews the plans or inspects the structure, which is why lenders and insurers often ask for more. And the other rules do not go away: Minnesota's electrical and plumbing rules apply statewide whether or not a township enforces the building code, and zoning, any shoreland or floodplain permit, the septic permit under the local ordinance and a well notification filed with the Minnesota Department of Health apply everywhere in the state.

Permits & Approvals: how the work runs

Four stages, in this order. The sequence matters more than it looks: finding out who enforces the building code on your land, where the septic system and well can go, and getting footings in before the ground freezes is what keeps a Minnesota build on schedule.

1

Find who has jurisdiction

We check who enforces the building code for the parcel, who administers zoning, shoreland and floodplain rules, and which office permits septic systems. In Minnesota these can be three different offices: a city, a township and the county.

2

Zoning and land-use approvals

Setbacks, lot size, any conditional use or variance, and shoreland or floodplain permits come first, because the building permit usually will not be issued without them. A home is not an agricultural building, so a farm parcel does not exempt it.

3

Building permit application

Where the code is enforced, we prepare the plan set to the 2020 Minnesota Residential Code with the frost depth, snow load, energy and radon details the reviewer will look for, and handle the permit application and any revisions.

4

Inspections through final

Footings, framing, insulation and final inspections are scheduled as the build reaches each stage, with the trade inspections for plumbing, electrical and HVAC carried by the licensed trade contractors doing that work.

Ask first

In Minnesota, the first permit question is who enforces the code at all

A city, a township or the county may enforce the State Building Code on your land, or nobody may. The code applies either way, but the permit, the plan review and the inspections exist only where it has been adopted. The Department of Labor and Industry's jurisdiction lookup is where every Minnesota permit path starts.

Where we deliver permits & approvals

In Minnesota the line that matters is often invisible on a map: whether the city, township or county your land sits in has adopted the State Building Code. Where one has, that office issues the building permit and inspects; where none has, the code still applies but nobody checks it. Zoning can be township or county, a shoreland ordinance governs land near lakes and rivers, and septic systems are permitted under a county, city or township ordinance. The snow load and frost depth the state sets change by county too, heavier and deeper across much of the north than in the south.

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Local permit fees

    Building permit and plan review fees are set by the city, township or county that issues the permit, and they vary widely. Where nobody enforces the code, there is no building permit fee, though zoning and septic permits still carry fees.

  • Zoning approvals

    A permitted use on a large rural lot may need only a zoning permit. A conditional use, variance or shoreland permit adds time, hearing notices and sometimes survey or engineering work.

  • Septic permit and soil work

    The septic permit, soil evaluation and design are carried out by businesses licensed for that work and priced by them. Some local ordinances add requirements beyond the state rules.

  • Plan review revisions

    A complete, code-ready plan set is the cheapest permit strategy. Each revision round adds drawing time and delays the start.

Permits & Approvals in Minnesota: common questions

8 questions we get asked most often about building in Minnesota. If yours is not on the list, ask it directly.

Are barndominiums allowed in Minnesota?
Yes. Minnesota treats a barndominium as a house like any other under the State Building Code, and whether one is allowed on a particular parcel depends on local zoning and, near water, the shoreland ordinance. Our legal guide covers the detail.
Do I need a building permit for a barndominium in Minnesota?
If your city, township or county has adopted the State Building Code, yes, and that office reviews the plans and inspects the build. If none of them has adopted it, there is no local building permit, but the code still applies, state electrical and plumbing rules still apply, and so do zoning, septic and well rules.
How do I find out if my township enforces the building code?
The Department of Labor and Industry's State Building Code jurisdiction lookup shows, for a city or township and county, whether the code has been adopted and who administers it. We check it for every parcel and confirm with the local office.
Which building code applies to a barndominium in Minnesota?
The 2020 Minnesota Residential Code, which is the 2018 International Residential Code as amended by Minnesota, plus the state's special provisions on frost depth, snow load and radon and the residential energy code.
Is a barndominium on farmland exempt as an agricultural building?
No. Minnesota's agricultural building exemption covers structures on agricultural land that are designed, built and used to house farm implements, livestock or agricultural products. A house is not one, even on a farm, and even when it shares a roof with a machine shed.
Who issues the septic permit?
The county, city or township that administers the septic ordinance for your area, under state rules set by the Minnesota Pollution Control Agency. Every county must have a septic ordinance covering the areas that do not have their own.
Do I need a permit for a well?
A well notification is filed with the Minnesota Department of Health before a new well is drilled, and the well is drilled by a licensed well contractor. State law says that notification preempts local well permits unless the Department of Health has delegated that authority.
Do you handle the permits?
We handle the building permit application and inspections where the code is enforced, and we line up the zoning and shoreland approvals the build needs. Septic permits and well notifications go through the licensed professionals who design and drill them.
