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

Setback minimums in the Village of Ashwaubenon run through two linked sections of Chapter 17: Table 17-5-100(A) and (B) set the base front, side and rear yard figures by zoning district, and Section 17-5-200(C) Required Yards supplies the measurement rules and district-matching requirements that modify those base numbers. Under § 17-5-200(C)(1)(a), when a lot is bounded on more than one side by a public right-of-way, the minimum yard between every structure and every right-of-way edge follows the required front-yard standard in Table 17-5-100(A), not just a single street-facing side.

Commercial and public-district lots do not get a fixed side-yard number of their own where they touch a residential zone: § 17-5-200(C)(1)(b) requires a lot abutting R-1, R-2 or R-3 to carry the same side-yard depth the abutting residential zone requires. The same abutting-zone rule extends to rear yards under § 17-5-200(C)(1)(d)(ii). Industrial districts get a specific floor: an I-1, I-2 or IP lot that abuts a residential zone anywhere along its rear lot line owes a minimum 25-foot rear yard. Corner lots in R-1 and R-2 owe a rear yard as deep as their required side yard, per § 17-5-200(C)(1)(c).

Swimming pools carry their own setback under § 17-5-200(C)(1)(g): in the R-1, R-2, RE and R-3 districts a permanent pool needs 10 feet of side yard and 10 feet of rear yard, both measured from the water's edge rather than the pool deck or equipment pad. Building walls set within three feet of a side or rear lot line also trigger a foundation requirement, extending the foundation wall to at least 10 feet below grade. Encroachments such as roof overhangs of 24 inches or less, unenclosed stairways projecting up to 5 feet, and porches or decks up to 50 square feet are allowed to intrude into an otherwise required yard.
