Black Earth is a small village in western Dane County along Black Earth Creek. Like many smaller Wisconsin communities, Black Earth's zoning code predates the recent wave of ADU-friendly legislation and may not have explicit ADU provisions. A second dwelling unit on a residential lot may require a conditional use permit, and the village's planning committee reviews these applications individually. Wisconsin's expanding state preemption of local ADU restrictions may change what's available here. We confirm eligibility for your specific parcel at no cost during the feasibility check.

What Governs ADUs

Common ADU Regulation Categories

Regardless of municipality, these are the regulatory areas that affect every ADU project in Dane County. Understanding them early prevents surprises later.

01 — ZONING
Zoning District & Use Classification

ADUs are only permitted in certain zoning districts. Most single-family and two-family residential zones qualify, but mixed-use and commercial zones have different rules. Your parcel’s zoning classification is the first thing we verify.

02 — SIZE
Maximum Unit Size

Most Dane County municipalities cap ADU size at 800–900 sq ft or a percentage of the primary home’s square footage, whichever is less. This directly affects what floor plans are achievable on your property.

03 — SETBACKS
Rear, Side & Front Setbacks

Setbacks define how close an ADU can be placed to property lines. These vary by zone and municipality — and they’re what most often determine where on a lot an ADU can physically be placed.

04 — HEIGHT
Maximum Structure Height

ADU height limits typically range from 18 to 25 feet depending on the municipality and zone. Height matters for garage ADUs and any structure with a loft or second level.

05 — UTILITIES
Utility Connection Requirements

ADUs typically require separate utility connections — water, sewer, and electrical. Connection capacity, tap fees, and access to existing lines all affect feasibility and cost. Wisconsin winters also require engineering decisions for water and drain lines.

06 — PARKING
Off-Street Parking Requirements

Some municipalities require one off-street parking space per ADU. Others — including Madison in many districts — have reduced or eliminated this requirement. It depends on your parcel’s location and zone.
