Significant challenges

Wells

Growing season
Short. Start seeds indoors and favor cold-hardy crops.

Is it legal here?

Zoning
Cook County zones land outside its towns and publishes its zoning map. Our free lookup shows the district for any address.

The Minnesota State Building Code (the 2018 International Residential Code with Minnesota changes, for homes) applies statewide, but a city, township, or county enforces it only if it has adopted the code by ordinance. Whether a new home needs a building permit depends on that local adoption, so ask the city, township, or county.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.
Water rights
Owners of land along a creek or lake can make reasonable use of its water.
