Setbacks & Height Limits in Madison

This guide explains the basic setback and height rules that apply to residential construction in Madison, Wisconsin. These numbers depend on your exact zoning district, overlay zones, and lot geometry, so always confirm with the City of Madison Planning Division before finalizing plans.

What Are Setbacks?

A setback is the minimum required distance between a building and a lot line. Setbacks are measured from the property line to the nearest point of the building (typically the wall, but eaves, bay windows, and chimneys have their own encroachment rules under Chapter 28).

Madison's Zoning Code (Chapter 28 of the General Ordinances) specifies front, side, and rear yard requirements separately for each zoning district. Corner lots have two "front" or street-facing yards and typically one interior side and one rear yard.

Typical Residential Setbacks

For the most common Madison residential zones, Chapter 28 requires approximately:

These are the base district values. Your specific lot may have different requirements based on adjacent setbacks (Madison uses a "contextual" front yard rule in many districts, averaging neighbors), overlay zones, or historic district review.

Height Limits

Maximum building height in Madison's core single-family residential districts is 35 ft, measured from the average grade at the building foundation to the highest point of a flat roof (or to the midpoint of a pitched roof) under Chapter 28 definitions.

Traditional Residential - Urban districts are slightly taller:

• TR-U1 — up to 40 ft (generally three stories)
• TR-U2 — up to 50 ft (three to four stories)

Height rules get more complicated in:

• Downtown and Capitol Center (CC) — height is capped by the Capitol view preservation ordinance, which protects sightlines to the State Capitol dome
• Historic districts — Mansion Hill, Third Lake Ridge, and other designated districts require Landmarks Commission review that can cap height by context
• Airport Height Limitation overlay — around Dane County Regional Airport
• Lakeshore / shoreland zones — additional DNR-coordinated setback and height rules near Lakes Mendota and Monona

Lot Coverage and Usable Open Space

Madison uses usable open space requirements instead of a simple "lot coverage" percentage in most residential districts. Chapter 28 generally requires:

• SR-C1 / SR-C2: approximately 40% usable open space
• SR-V1 / SR-V2: approximately 30–40% usable open space
• TR-C1 / TR-C2: approximately 30% usable open space
• TR-U1 / TR-U2: lower percentages, often tied to unit count

Beyond usable open space, Madison does not apply a city-wide Floor Area Ratio (FAR) to single-family districts. Downtown and mixed-use districts (UMX, NMX, CC) use FAR and step-back rules instead.

Common Exceptions and Encroachments

Chapter 28 (Section 28.132 and related) allows certain features to project into required setbacks. Typical allowances include:

• Eaves and gutters (usually up to 2 ft)
• Chimneys (up to 2 ft)
• Uncovered porches, stoops, and steps
• Air conditioning condensers (subject to noise limits)
• Bay windows (limited projection)

Fences, retaining walls, and accessory structures (garages, sheds, ADUs) have separate yard rules — see the accessory structure section of Chapter 28 and the Madison ADU ordinance.

State ADU Overrides

If your project is an Accessory Dwelling Unit (ADU), Wisconsin does not have a statewide ADU mandate — Madison's local ADU rules in Chapter 28 control. Detached ADUs have a maximum footprint of 1,000 sq ft and a maximum height of 25 ft, and the ADU or main house must be owner-occupied. See the ADU rules page for the full Madison requirements.

How to Look Up Your Specific Requirements

1. Find your zoning district — use the Madison zoning map
2. Read the district regulations — Chapter 28 of the Madison General Ordinances on Municode lists setbacks, height, open space, and use rules
3. Check for overlays — Capitol view, historic districts, airport, and shoreland overlays can modify the base rules
4. Ask Zoning staff — call (608) 266-4551 or email [email protected] for a free zoning verification before you commit to design

Variances

If your project cannot meet the strict letter of Chapter 28, you may apply for a variance to the Madison Zoning Board of Appeals (ZBA) — a formal request to deviate from the rules based on unnecessary hardship specific to your lot. Variances are discretionary and require a public hearing. See the Variance Application Guide for the general process.
