Neither Ramsey County nor Minnesota bans residential rainwater harvesting. Rain barrels and rain gardens are actively promoted for stormwater management, and Ramsey County and its watershed districts have offered cost-share grants for them.
There is no county or state prohibition on collecting rainwater from your roof for lawn and garden use. Minnesota does not follow the water-rights doctrines that restrict rain capture in some western states. Ramsey County, the Capitol Region and Ramsey-Washington Metro watershed districts, and the city of Saint Paul promote rain barrels and rain gardens as best practices to reduce stormwater runoff and protect lakes and the Mississippi River, and have run cost-share and grant programs to help residents install them. Confirm any HOA rules, which are private and separate from government regulation.
No penalties — residential rainwater harvesting for outdoor use is unregulated and encouraged; no permit is required for typical rain barrels.
