Summary

In the A-160 Agricultural District, Stearns County sets a flat 50-foot side and 50-foot rear building setback, plus a road-classification table controlling front setbacks that runs from 30 feet off a private road easement up to 150 feet off a principal arterial's centerline.

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.

Minimum building setbacks: (1) Side 50 feet (2) Rear 50 feet (3) Front [Road Classification table: Principal Arterial 150/75; Minor Arterial 120/60; Major Collector 100/50; Minor Collector 100/50; County Road 100/50; Township Road 63/30; Private Road Esmt. 63/30. THE MORE RESTRICTIVE SETBACK SHALL APPLY.] (4) Detached garages and accessory buildings may be placed ten (10) feet from the side lot line and ten (10) feet from the rear lot line.

Full Breakdown

11(A) of Ordinance 439 spells out the A-160 district's minimum building setbacks in three parts. Side and rear setbacks are a flat fifty feet each. Front setbacks instead run off a road-classification table measured from both the road centerline and the right-of-way, with the more restrictive of the two controlling: a Principal Arterial requires 150 feet from centerline or 75 feet from right-of-way; a Minor Arterial requires 120 feet from centerline or 60 feet from right-of-way; a Major or Minor Collector requires 100 feet from centerline or 50 feet from right-of-way; a County Road requires 100 feet from centerline or 50 feet from right-of-way; and a Township Road or private road easement requires 63 feet from centerline or 30 feet from right-of-way.

Detached garages and accessory buildings get a reduced allowance, ten feet from the side lot line and ten feet from the rear lot line. For lots created after January 27, 2005, the section also layers on wetland setbacks: fifty feet from Type 3, 4 and 5 wetlands and twenty-five feet from all other wetlands. 11(C) adds that residential dwellings must also meet the separate residential setback from an animal feedlot required elsewhere in the Ordinance. 11 in the same chapter, so the applicable district must be confirmed on the county's Official Zoning Map before relying on the A-160 figures.

Violations & Fines

Building or expanding a structure inside these setbacks without an approved variance from the Stearns County Board of Adjustment creates a nonconforming structure that the Department can require to be relocated, altered or removed, and it blocks issuance of the construction site permit required under Section 4.11.1 until the encroachment is corrected or a variance is granted.

What is the side yard setback in Stearns County's A-160 district?
Fifty feet, per Section 9.1.11(A)(1) of Ordinance 439. The rear setback is also fifty feet under 9.1.11(A)(2), while the front setback instead depends on the classification of the adjacent road.
How close can I build a detached garage to my property line in Stearns County?
Section 9.1.11(A)(4) allows detached garages and accessory buildings as close as ten feet from the side lot line and ten feet from the rear lot line, tighter than the fifty-foot standard that applies to the principal dwelling.
Does the setback depend on which road my property is on?
Yes. Section 9.1.11(A)(3)'s table sets front setbacks by road classification, from 150 feet off a Principal Arterial's centerline down to 63 feet off a Township Road or private road easement centerline, with the more restrictive of the centerline or right-of-way figure applying.
