Building Setbacks & Zoning in De Pere, WI: What Residents Actually Need to Know

If you live in De Pere 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. De Pere has 2 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Lot Coverage Limits

On any De Pere lot with a backyard cottage, Zoning Ordinance Section 14-27(4)(k) caps the combined ground-floor footprint of every accessory building, including the cottage, at 850 square feet. Extra cottage floor area on a second story or in a basement doesn't count against that cap.

Key details: Cumulative cap: 850 sq ft for all accessory buildings. Applies on lots with: A backyard cottage present. Excluded area: Second floor or basement cottage space. Citation: De Pere Zoning Ordinance § 14-27(4)(k). Checked at: Building permit review by city.

Building or maintaining accessory structures, including a backyard cottage, that together exceed the 850-square-foot ground-floor cap violates Section 14-151 of the zoning ordinance. The city can withhold or revoke the associated building permit under Section 14-152(2), issue a municipal citation under municipal code Section 1-11, and treat each day the excess coverage continues after notice as a separate violation under Section 14-151(2).

Setback Rules

De Pere's zoning ordinance normally sets minimum front, rear and interior side setbacks by residential district, but Section 14-21(8) overrides those baseline figures whenever a neighborhood is already built up. Once at least half of the residential principal buildings within 300 feet of a lot exist, new construction must match the block's average setback instead of the district minimum.

Key details: Trigger: 50%+ of homes within 300 ft built up. Setbacks affected: Front, rear, and interior side only. Outlier rule: Buildings 30% off average can be discounted. Citation: De Pere Zoning Ordinance § 14-21(8). Administered by: Development services director, § 14-150.

Building or expanding a house without meeting the applicable setback, whether the district minimum or the neighborhood-averaged figure, is a zoning violation under Section 14-151. The city can withhold or revoke the building permit under Section 14-152(2), issue a municipal citation under Section 1-11 of the municipal code, or pursue other legal remedies under Section 14-152(4), and each day a violation continues after notice counts as a separate offense under Section 14-151(2).

The Bottom Line

De Pere'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 De Pere is broadly strict or permissive.
