Mille Lacs County, Minnesota
Onamia is a city in Mille Lacs County, Minnesota. Onamia adopts its own zoning, so inside its limits Onamia’s rules apply, not the county’s. 5 rules below are quoted from official sources and independently re-checked, most recently on November 5, 2026. Rules for unincorporated land are on the Mille Lacs County page.
Construction of a house, garage, or other structure, or exterior changes to an existing house, garage, or building, within Onamia city limits.
“Building permits are required when constructing a house, garage or other structure on property within the city limits or making changes to the exterior of an existing house, garage or building.”
Buildings subject to the Minnesota Accessibility Code inside Onamia city limits.
“The Minnesota Accessibility Code, established pursuant to M.S. §§ 326B.01 - 326B.998, as they may be amended from time to time, and as provided for in Minn. Rules Ch. 1341, as it may be amended from time to time, is adopted as the building code for accessibility in this city.”
Land inside Onamia city limits.
“This chapter, together with the zoning map required at § 151.05, shall be known as the City Zoning Ordinance except as referred to herein, where it shall be known as this Ordinance or this chapter.”
Onamia does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
Residential real estate in Onamia city, under Minnesota's statewide residential-contractor licensing exemption.
“(3) an owner of residential real estate who builds or improves residential real estate if the owner occupies or will occupy the residential real estate for residential purposes, or will retain ownership for rental purposes upon completion of the building or improvement. This exemption does not apply to an owner who constructs or improves residential real estate for purposes of resale or speculation.”
Agricultural buildings in Onamia city to the extent governed by the Minnesota State Building Code.
“(c) The State Building Code does not apply to agricultural buildings except: (1) with respect to state inspections required or rulemaking authorized by sections 103F.141; 216C.19, subdivision 9; and 326B.36; and (2) translucent panels or other skylights without raised curbs shall be supported to have equivalent load-bearing capacity as the surrounding roof.”
We looked and could not find an official answer yet. Silence is not permission; ask Onamia or Mille Lacs County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Onamia publishes no rule on the point, not that none exists. Mille Lacs County’s page lists the county offices to call.
