Building Setbacks & Zoning in Green Bay, WI

Green Bay maintains 101 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 Green Bay falls on the strict-to-permissive spectrum compared to other cities.

Lot Coverage Limits

Green Bay caps impervious surface, buildings, driveways, and paved areas, between 40% and 70% of a lot, with the limit set by zoning district: 40% in RR, 50% in R1, 60% in R2, and 70% in R3.

Key details: RR District cap: 40% impervious max. R1 District cap: 50% impervious max. R2 District cap: 60% impervious max. R3 District cap: 70% impervious max. Small pre-2015 lots: up to 80% allowed.

Site and building plans that exceed the district's impervious cap won't get zoning approval, and a lot already over the limit is nonconforming: it can't add more paved or built area without a variance.

Setback Rules

Front-yard setbacks in Green Bay's residential districts run 10 feet in RR, R-1, and R-2, and 20 feet in R-3, with 5-foot side yards and rear yards from 5 to 25 feet depending on the district.

Key details: Front yard, R-1/R-2/RR: 10 feet minimum. Front yard, R-3: 20 feet minimum. Side yard: 5 feet (6-8 ft in R-3). Rear yard: 5 feet (25 ft in R-3).

Building a house, addition, or attached garage closer to the lot line than Table 44-2 allows is a zoning violation under Sec. 44-198, subject to the Sec. 1-6 forfeiture of $1 to $500 per day the violation continues.

Structure Height Limits

Green Bay's residential zoning table, Table 44-2 under Municipal Code § 44-554, caps building height at 35 feet (2.5 stories) in the RR and R-3 districts, 35 feet (3 stories) in R-1, and 55 feet (5 stories) in R-2. Chimneys, steeples, flagpoles and similar features are excluded from the count under § 44-361(a).

Key details: RR height limit: 35 feet / 2.5 stories. R-1 height limit: 35 feet / 3 stories. R-2 height limit: 55 feet / 5 stories. R-3 height limit: 35 feet / 2.5 stories. Height increase route: Conditional use permit, § 44-83.

Building above the district's height limit without a conditional use permit under § 44-83 violates Chapter 44 and is enforceable under §§ 44-197 and 44-198: the Zoning Administrator, Plan Commission, Common Council, or a damaged neighboring property owner can sue to enjoin construction or force removal, and a court can impose the § 1-6 forfeiture of $1.00 to $500.00, with each day of the violation counted separately.

The Bottom Line

Green Bay'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 Green Bay is broadly strict or permissive.
