Minnesota: Laws & Legal Considerations

Download all of Minnesota as PDF Print

Minnesota’s Department of Natural Resources actively encourages rainwater harvesting as a conservation practice, but the actual installation process is more involved than the simple permit-free rule most other states covered on this site use.

RuleMinnesota
Source water Roof surfaces made of hard, impervious material specifically
Permitted uses Non-potable
Installation requirement Commissioner approval is required to install, build, change, or fix a rainwater-catching system
Underlying rule Minn. Stat. §4714.1602.7.4

Why this is a meaningfully different process than most states covered so far

Most states covered on this site let a resident install a basic rooftop rain barrel with no state involvement at all. Minnesota’s commissioner-approval requirement is a genuine, if modest, additional step, worth planning for before assuming a simple rain barrel needs no state-level sign-off.

Where to find it: the Minnesota Department of Natural Resources (dnr.state.mn.us) administers approval and general water law guidance.

Water rights: riparian, comparatively permissive next to Western states

Minnesota follows the common-law riparian doctrine, limited by reasonable use, the same broad family as most Midwestern and Eastern states covered on this site.

ConceptHow it works in Minnesota
Who holds the right Owners of land riparian to a water source
Governing principle Reasonable use for domestic, agricultural, and manufacturing purposes

Where to find it: the Minnesota DNR administers water rights and appropriation permits statewide.

Permit to Carry: required, unlike some neighboring states

Minnesota requires an actual Permit to Carry, a meaningful contrast with neighboring states like Indiana and Ohio’s permitless systems covered elsewhere on this site.

RequirementDetail
Standard A Permit to Carry is required to carry a handgun in public at all, concealed or not
Minimum age 21
Training required Certified handgun safety training within one year of application or renewal
Issuing authority The county sheriff where the applicant resides (nonresidents may apply to any Minnesota county)
Cost and validity $100 initial fee (capped by law), $75 renewal, valid 5 years
Processing time Up to 30 days

One practical benefit of holding the permit

A Minnesota Permit to Carry holder doesn’t need a separate Permit to Purchase when buying a firearm, the carry permit itself satisfies that requirement.
