Buying Land in Brown County, Minnesota
Brown County, seat New Ulm, runs an unusually consolidated land-use program: one Planning & Zoning Department handles the county zoning ordinance and subdivision regulations, building permits, on-site septic permitting, Wetland Conservation Act enforcement, and even agricultural/weed inspection for the unincorporated county. The county's own zoning ordinance explicitly states agricultural land preservation as a core purpose. The city of New Ulm, the county seat and largest city, administers its own separate zoning and building code entirely apart from the county office -- confirm which one actually governs a specific parcel before relying on either.
Zoning, permitting, and septic: one department for the unincorporated county
Brown County administers land use in its unincorporated territory through a single Planning & Zoning Department, reachable at (507) 233-6640 from the Brown County Courthouse in New Ulm. That one office coordinates the County Zoning Ordinance and Subdivision Regulations, works with all conditional use permit and variance applications, staffs the County Planning Commission (which makes recommendations to the County Board on conditional use permits, subdivision plats, and ordinance amendments), issues building permits, and runs the on-site sewage treatment system (SSTS/septic) permitting and inspection program. The county's Zoning Ordinance, last updated January 17, 2023, states its governing purposes directly: protecting and preserving agricultural land, conserving the county's natural and scenic beauty, minimizing environmental pollution, and -- a less common inclusion -- conserving energy by allowing solar access and earth-sheltered housing designs.
The city of New Ulm -- the county seat and Brown County's largest city -- runs its own separate zoning, planning, and building code through its own City Hall, entirely apart from the county's Planning & Zoning Department. Before assuming county zoning, permitting, or septic rules apply to a specific parcel, confirm whether the address sits inside New Ulm (or another incorporated city in the county) and, if so, contact that city directly rather than the county office.
Shoreland and wetlands: shoreland folded into the general ordinance, county as WCA LGU
Unlike some Minnesota counties that maintain shoreland management as a wholly separate ordinance chapter, Brown County's shoreland provisions are incorporated directly within its general Zoning Ordinance, implementing the state's Chapter 6120 shoreland framework for land near the county's lakes, and the Minnesota and Cottonwood Rivers, through the same office and the same document that governs general zoning. For a specific parcel's shoreland classification and setback requirements -- which, per the state hub, are a floor the county may exceed -- confirm directly with Planning & Zoning rather than assuming the general zoning district standards are the only ones that apply near water.
For Wetland Conservation Act purposes, Brown County itself serves as the local government unit (LGU), with a Technical Evaluation Panel that draws on Brown Soil and Water Conservation District staff alongside BWSR and DNR representatives to make wetland determinations. This is enforced through the same Planning & Zoning Department that handles general zoning and building permits, which is a genuine administrative convenience -- but it does not resolve who administers WCA within New Ulm's city limits, which we could not independently confirm; ask both the city and the county directly for any parcel in or near New Ulm with a wetland or low-lying area.
Who to Call Before Buying Land in Brown County
We could not confirm a direct department email for Planning & Zoning (the county's own site links to a webform rather than a published address) or direct phone/email for the county's GIS/Maps function beyond its listed webpage -- call Planning & Zoning's main line and ask to be directed if a specific contact isn't listed here. We also could not confirm whether the city of New Ulm administers zoning, building permits, or Wetland Conservation Act determinations separately within its own city limits, or exactly how; the city runs its own zoning and building code through its own City Hall, so any parcel inside New Ulm (or another incorporated city in the county) should be confirmed with that city directly rather than with the county offices listed above.
