Portage County, WI Building Setbacks & Zoning: Setback Rules (2026)

Portage County's zoning ordinance, Chapter 7.1 of the Code of Ordinances, sets side and rear yard setbacks separately for each of the county's zoning districts, and those setbacks govern only in the towns that have adopted county zoning rather than in Stevens Point, Plover or the county's other incorporated cities and villages, each of which enforces its own code. Under Section 7.1.2(1)(d), the Single Family Residence District (R2) requires a ten-foot minimum setback from each side yard and a 25-foot minimum setback from the rear yard.

Under Section 7.1.3(4)(d), the Exclusive Agricultural District (A1), which covers most of the county's farmland outside the incorporated municipalities, sets a larger 25-foot minimum side yard alongside the same 25-foot rear yard, and pairs that with a 200-foot minimum lot width and a 35-acre minimum farm site for any dwelling. Both sections cross-reference Section 7.1.6(6), the county's separate road-setback table, which measures building setbacks from the centerline or right-of-way of the abutting highway rather than from the interior lot lines: Class 1 highways (state and federal roads) require 110 feet from centerline or 50 feet from the right-of-way, whichever is greater, and Class 2 highways (county roads) require 75 feet from centerline or 42 feet from the right-of-way.

The Planning and Zoning Department reviews setback compliance when it issues a zoning permit under Section 7.1.6(2), and the Board of Adjustment can grant relief where a lot's width falls short of the district minimum.
