Building Setbacks & Zoning in Fitchburg, WI

If you live in Fitchburg or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Fitchburg has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Lot Coverage Limits

In Fitchburg's R-L Low Density District, buildings and other lot coverage cannot exceed 35 percent of the lot under the zoning code's dimensional standards. The Rural Density district caps coverage lower, at ten percent, while a plan-commission-approved cluster development can go up to 40 percent.

Key details: R-L max lot coverage: 35% (§ 22-58(8)). R-LM max lot coverage: 35% (§ 22-92(8)). R-H max lot coverage: 35% (§ 22-146(9)). R-R max lot coverage: 10% (§ 22-208(8)). Cluster development max: Up to 40% by conditional use.

Exceeding the lot-coverage cap is enforced the same way as any other Chapter 22 zoning violation. The zoning administrator can issue a written demand to halt or remedy the excess coverage, and under § 22-648(d)(2) noncompliance carries a forfeiture of $100.00 per day. Uncorrected violations go to the city attorney, who can seek an injunction requiring the owner to remove or reduce the offending structure or paved area. Owners believing strict enforcement causes an unnecessary hardship can seek a dimensional variance from the zoning board of appeals under § 22-644.

Setback Rules

Fitchburg's R-L Low Density District requires a 30-foot front setback, ten-foot side setback, 25-foot street-side setback on corner lots, and 35-foot rear setback, with specific exceptions for porches, reduced side yards backed by deed restrictions, and screen porches.

Key details: R-L front setback: 30 ft (25 ft for open porch/stoop). R-L side setback: 10 ft, reducible to 5 ft by deed restriction. R-L street-side setback: 25 ft on corner lots. R-L rear setback: 35 ft (25 ft for CU screen porches). Governing section: Fitchburg City Code § 22-58.

Building within a required setback without an approved reduction or variance is a Chapter 22 zoning violation. The zoning administrator investigates under § 22-648(c) and can demand the encroachment be halted, prevented or remedied before referring the matter to the city attorney for prosecution or an injunction. Section 22-648(d)(2) sets the penalty at a forfeiture of $100.00 per day for noncompliance. A property owner seeking relief from a setback figure can request a dimensional variance from the zoning board of appeals under § 22-644, which requires showing that strict enforcement creates an unnecessary hardship tied to the specific property.

Structure Height Limits

Fitchburg caps residential structures in the R-L Low Density District at 35 feet or three stories, whichever is less, under the zoning code's dimensional standards, with conditional-use exceptions for institutional buildings and taller structures in higher-density districts.

Key details: R-L max height: 35 ft or 3 stories, whichever is less. R-H max height: 45 ft/3 stories, CU up to 75 ft/6 stories. R-R max height: 35 ft or 3 stories. Accessory structure cap: No taller than house, max 15 ft. Institutional exception: CU approval under § 22-6(a).

A structure built above its district's height limit without an approved exception is a Chapter 22 zoning violation, enforced by the zoning administrator under § 22-648. The administrator can issue a demand to halt construction or require the excess height be removed, and § 22-648(d)(2) sets a forfeiture of $100.00 per day for noncompliance. The city attorney can pursue an injunction to force compliance. An owner who believes the height limit creates an unnecessary hardship on a specific lot can apply for a variance to the zoning board of appeals under § 22-644.

The Bottom Line

Fitchburg'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 Fitchburg is broadly strict or permissive.
