How Wausau Handles Building Setbacks & Zoning: A Practical Guide

Wausau maintains 127 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Wausau falls on the strict-to-permissive spectrum compared to other cities.

Lot Coverage Limits

Wausau's Title 23 zoning code caps how much of a lot can be covered by buildings and paved surface, expressed as a maximum impervious surface ratio in each district's bulk table. In the SR-2 Single Family Residential-2 district, the city's most common single-family zone, the limit is 45 percent on a minimum 15,000-square-foot lot, enforced by the Division of Inspection, Zoning and Electrical Systems.

Key details: Max impervious surface (SR-2): 45 percent of lot area. Minimum lot area (SR-2): 15,000 square feet. Minimum lot width (SR-2): 100 feet. Governing law: Title 23 Zoning, eff. Jan. 1, 2020. Enforcing agency: Div. of Inspection, Zoning & Electrical Systems.

Building or paving beyond the maximum impervious surface ratio is an unlawful land use under Wausau Municipal Code Section 23.10.60(1), which bars any development activity that violates Title 23. The City reserves the right to order abatement and bill the property owner for the cost under Section 23.10.60(3). Because Title 23 sets no separate fine for this violation, the general municipal penalty in Section 1.01.110 applies: a forfeiture of not less than $10.00 nor more than $200.00 per offense, with each day a violation continues charged as a separate offense.

Setback Rules

Wausau's Title 23 zoning code sets minimum front, side, rear and street-side setbacks for every zoning district in its own bulk table. In the (SR-2) Single Family Residential-2 district, the city's standard single-family zone, the code requires a 25-foot front setback, a 10-foot side setback and a 30-foot rear setback, enforced by the Division of Inspection, Zoning and Electrical Systems.

Key details: Front setback (SR-2): 25 feet. Side setback (SR-2): 10 feet. Rear setback (SR-2): 30 feet. Street side setback (corner lots): 30 feet. Accessory building rear setback: 5 feet.

Erecting a structure that intrudes into a required Wausau setback is an unlawful use of land under Wausau Municipal Code Section 23.10.60(1). The City may order the encroachment abated and bill the owner for the cost under Section 23.10.60(3), and, absent a specific fine in Title 23, the general municipal penalty in Section 1.01.110 applies: a forfeiture of $10.00 to $200.00 per offense, with each day of the encroachment treated as a separate offense; a property owner may instead seek a variance from the Zoning Board of Appeals under Section 23.10.51.

Structure Height Limits

Wausau's Title 23 zoning code caps residential building height by district in its bulk regulations table. In the (SR-2) Single Family Residential-2 district, the city's standard single-family zone, the maximum principal building height is 35 feet, while detached residential accessory buildings are limited to 22 feet, enforced by the Division of Inspection, Zoning and Electrical Systems.

Key details: Max principal building height (SR-2): 35 feet. Max accessory height (residential): 22 feet. Max accessory height (nonresidential): 18 feet. Exempt features: Spires, towers, chimneys, antennas (§23.04.20). Airport overlay: Lower cap may apply (§23.04.10(3)).

Constructing a principal building taller than the district's 35-foot limit, or an accessory structure over its 22-foot or 18-foot cap, is an unlawful land use under Wausau Municipal Code Section 23.10.60(1) unless the structure falls within the Section 23.04.20 exemptions or holds a variance. The City may order the violation abated and charge the property owner for the cost under Section 23.10.60(3); absent a specific fine, the general municipal penalty in Section 1.01.110 applies, a forfeiture of $10.00 to $200.00 per offense, with every day the structure remains oversized counted as a separate offense.

The Bottom Line

Wausau's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Wausau is broadly strict or permissive.
