Minnesota ranks among the top seven most ADU-friendly states, but is also among the most difficult to navigate. While many cities and towns allow accessory dwelling units, there’s little to no clear guidance at the state or county level, leaving homeowners uncertain about what’s actually allowed.

To clear things up, we’ve put together this guide. Below, you’ll find a breakdown of ADU rules by state, county, and city so you can determine what’s permitted in your area.

Many cities and towns in Minnesota allow ADUs. However, there are no statewide regulations for ADUs. Therefore, you must check with your local officials, as the answer to this question depends entirely on where you live.

ADUs That Are Allowed in Minnesota

Most areas in Minnesota that allow ADUs require a minimum size of 200 to 300 square feet and a maximum of 700 to 1,000 square feet. Below are all ADU models that fall within those limits. However, as noted above, local regulations vary, so keep reading to find out if one of these models meets your area’s requirements.

What qualifies as an ADU in Minnesota can vary significantly based on your location. Some areas only allow attached units, while others permit attached, detached, and conversion ADUs.

In addition, structures like park models, cabins, and sheds may be considered ADUs depending on local regulations. To help clarify what’s allowed across the state, we’ve broken down some of these options in more detail below.

Can Park Model Tiny Homes Be Used As ADUs?

Yes and no—it depends on where you live. Some areas strictly prohibit any “tiny home on wheels,” including park models, from being used as ADUs, while others allow them. Keep reading to learn more about your area’s requirements.

Can Cabins From Zook Cabins Be Used As An ADU?

Yes, so long as they meet your local size requirements, which typically range from 200 to 1,000 square feet, our cabins can be used as ADUs. This includes our modern cabins, log cabins, and luxury mobile homes. Below are some of our models that align with Minnesota’s standards.

What is the Difference Between a Prefab ADU & a Modular ADU?

This is our 1-bedroom A-frame ADU

Prefab and modular ADUs differ in how they are built. Prefab units are constructed entirely off-site and delivered fully assembled. Modular ADUs, by contrast, are built in sections off-site and then assembled on-site.

To learn more about the differences between the two, check out our comparison guide between prefab and modular ADUs.

Size & Placement Requirements

The size and placement of your ADU are key factors in defining it as an “accessory” dwelling unit. In many cases, it must be located a certain distance from the primary home and must be smaller in size. These requirements help maintain its status as a secondary structure. Below, we’ll outline some common size and placement standards your ADU may need to meet.

Feel free to jump to the city section to see your area’s requirements.

What is the Minimum Size for an Accessory Dwelling Unit?

In most areas of Minnesota, ADUs must be at least 200 to 300 square feet. However, exact size rules can vary, so be sure to contact your local officials to confirm what applies in your area.

Can My ADU Be Bigger Than My House?

No, ADUs cannot be larger than your primary home. In most cases, their size is capped at a percentage of your main residence, typically between 30% and 75%. To find out what applies in your area, keep reading.

What is the Minimum Distance Allowed Between Your Home and Your ADU?

The exact minimum varies by city or town, but in most cases, your ADU must be at least 10 feet from the primary residence.

Do You Need A Permit For An ADU in Minnesota?

Rendering of the 2-bedroom Luna ADU with wood paneling

Yes, in most cases, an ADU will require a building permit. Some areas may also require zoning approval, a special use permit, or other documentation as outlined in the local code. To determine exactly what permits are needed, contact your local building, planning, or permitting office.

Are There Any Incentives or Grants for ADUs in Minnesota?

There are currently no statewide or local grants for ADUs in Minnesota. However, there are several grant programs in Minnesota that may apply. 

What Features are Included in An ADU from Zook Cabins?

While specific features vary by model, our ADUs offer a range of modern designs with various floor plans, allowing you to select the one that best fits your needs, including:

  • Fully finished interiors
  • Floor plans featuring multiple bedrooms and bathrooms
  • Sizes ranging from 571 to 848 sq. ft.
  • Heating & cooling options
  • Insulation
  • Options for front porches or loft spaces
  • Living Areas with plenty of natural light

It’s important to note that certain interior features, such as countertops, tile work, and cabinet colors, can be upgraded to better match your preferences. Talk to your sales representative to learn more about available customization options.

Are Zook Cabin’s ADUs Built to Code?

Yes! Our models are specifically designed to meet local size and room requirements. Because they are modular homes, they must be installed on a permanent foundation to comply with local building codes. Zook Cabins will help you choose the foundation type that best fits your property and meets local requirements.

Can an ADU Have Multiple Bedrooms and Bathrooms?

Yes, they can, although some areas in Minnesota limit ADUs to a maximum of two bedrooms. At Zook Cabins, our Grove, Luna, and A-Frame models offer one to two-bedroom layouts with full bathrooms, providing flexible multi-room configurations that meet Minnesota’s requirements.

Are ADUs A Good Investment?

Yes! ADUs make excellent rental units. Depending on local owner-occupancy rules, you may even be able to sell the unit separately from your primary home. And even if a separate sale isn’t allowed, adding an ADU can significantly increase your property’s overall value.

What Are the Requirements for ADUs in Each County in Minnesota?

Minnesota has no statewide or countywide laws regarding ADUs, which means there are no specific requirements for unincorporated areas beyond what is outlined in the 2020 Minnesota Building Code. However, standards do apply if you live within a city or town’s jurisdiction. To learn more about whether your city or town permits ADUs, you can skip ahead to see their requirements.
