Summary

Stearns County requires a construction site permit before anyone erects, alters or moves a structure, or excavates footings, foundations or basements, anywhere in the unincorporated county. Applications go to the Environmental Services Department and permits expire after one year if construction has not started.

These county ordinances apply to unincorporated areas of Stearns County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Except as provided in Section 6.0, 6.2.1 D, 6.54.2 and 7.22.1C of this Ordinance, no person shall erect, alter or move any structure or part thereof without first securing a construction site permit. Additionally, no excavation for footings, foundations, slabs, posts, basements, walls or other parts of a structure shall be conducted without first securing a construction site permit.

Full Breakdown

1(C) of the Ordinance (these cover things like small agricultural accessory buildings and other listed exemptions). 2 requires the application to go to the Department on its own forms, accompanied by a scaled plan showing lot dimensions and the size and location of the structure, plus enough information for the Department to confirm the site can support a conforming sewage treatment system. A complete application for a structure whose use involves protected expression must be reviewed and either issued or denied within sixty days. 3 sets the permit's life: it lapses and becomes null and void after one year if construction has not begun; once construction (installation of footings, slabs, foundations, posts or walls, or the excavation for them) has started within that year, the permit is extended one additional year to finish the work.

Site prep, land clearing or utility installation alone does not count as "construction" for this clock. 4 requires a certificate of survey and staking, prepared by a Minnesota-licensed land surveyor, whenever the proposed construction sits closer than one and a half times the property-line setback (excluding the ordinary-high-water-level setback). 5 gives incomplete applications six months to be completed before they expire outright.

Violations & Fines

Building without the required construction site permit, or letting an issued permit lapse and continuing work anyway, is a zoning violation enforceable by the Stearns County Environmental Services Department under the Ordinance's general enforcement provisions, which can require the work to stop and the site brought into compliance before any further construction proceeds. A lapsed permit (no construction started within one year) must be reapplied for from scratch, and an incomplete application not finished within six months expires and must be resubmitted.

Frequently Asked Questions

Do I need a permit to add a garage in unincorporated Stearns County?
Yes, unless a specific exemption in Sections 6.0, 6.2.1(D), 6.54.2 or 7.22.1(C) applies. Section 4.11.1 requires a construction site permit before erecting, altering or moving any structure, including detached garages, and before excavating footings or foundations for one.
How long is a Stearns County construction site permit good for?
One year from issuance if you have not started construction, per Section 4.11.3. If you break ground on footings, slabs or walls within that year, the permit is automatically good for one more year to finish the job.
When does Stearns County require a certificate of survey?
Section 4.11.4 requires one, prepared by a Minnesota-licensed surveyor, whenever the proposed construction is closer than one and a half times the applicable property-line setback, not counting the ordinary-high-water-level setback.
