Read this before you act on anything below. This is my researched starting point for Brown County, MN, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesBrown County, MN

Zoning & raw-land occupancy

Varies locallyBrown County Planning & Zoning administers a Zoning Ordinance and Subdivision Regulations in unincorporated areas only; incorporated cities like New Ulm, Sleepy Eye, and Springfield have their own zoning offices instead. source

Dwellings, tiny homes & RVs

Unclear - verifyThe county ordinance regulates manufactured homes explicitly (foundation, anchoring), but whether tiny homes or RVs qualify as permanent dwellings isn't spelled out; the Zoning Administrator would decide case by case. source

Building permits & codes

RestrictedMinnesota State Building Code is the statewide minimum, and Brown County Planning & Zoning enforces it with permits and inspections in unincorporated areas; cities handle their own permitting. source

Septic & composting toilets

Generally allowedBrown County must run an SSTS program under state pollution control rules and issues ISTS (septic) permits and inspections through Planning & Zoning; composting toilets appear allowed under the state framework but confirm local specifics. source

Greywater reuse

Unclear - verifyNo Brown County-specific greywater ordinance was found; confirm directly with Planning & Zoning whether the county's SSTS rules address greywater separately.

Rainwater harvesting

Unclear - verifyNo Brown County rainwater ordinance was found; statewide, indoor plumbed systems fall under Minnesota Department of Labor and Industry plumbing code while outdoor barrels are generally unregulated, but that's not a county-specific confirmation.

Private wells & water rights

Generally allowedWell construction is regulated statewide by the Minnesota Department of Health under state statute, with no separate Brown County well ordinance found; large withdrawals over 10,000 gallons/day need a DNR appropriation permit. source

Living disconnected from utilities

Unclear - verifyNo Brown County ordinance explicitly requires or bars grid disconnection; this would likely fall under general building/occupancy enforcement by Planning & Zoning or the relevant city, so confirm directly.
