Building Setbacks & Zoning in Milton, WI

If you live in Milton 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. Milton has 3 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Lot Coverage Limits

The City of Milton, Wisconsin does not cap building footprint directly. Instead it limits total impervious surface, driveways, patios and buildings combined, to 75 percent of the lot in the SR-7 single-family district and up to 80 percent in the Adult-Oriented, Intensive Outdoor Commercial, Extraction and Airport districts.

Key details: SR-7 max impervious ratio: 75 percent. SR-7 min green space: 25 percent. SR-7 max building coverage: None (no separate cap). AO/IOC/EX/Airport impervious cap: 80 percent. First-offense forfeiture: $50 to $500.

Exceeding the impervious ratio for a zoning district is a violation of Chapter 78, enforced by the zoning administrator under Sec. 78-10.60. Forfeitures follow the general penalty in Sec. 1-14: not less than $50.00 nor more than $500.00 for a first offense, plus costs of prosecution, with jail up to 90 days if unpaid; a second offense within the same provision runs $100.00 to $1,000.00, jail up to six months if unpaid.

Structure Height Limits

A principal house in the City of Milton's SR-7, SR-10, MH-7 and Adult-Oriented districts is capped at 35 feet under the Chapter 78 bulk table, while the Rural Holding, Intensive Outdoor Commercial and Extraction districts allow up to 50 feet.

Key details: SR-7/SR-10/MH-7/AO height cap: 35 feet. RH-35/IOC/EX height cap: 50 feet. Historic district residential new-build cap: 35 feet, Sec. 34-163. Historic district commercial new-build cap: 40 feet. Accessory structure height (SR-7): 18 feet max.

Constructing above the height limit for a district without a variance or historic-district exception is enforced by the zoning administrator under Sec. 78-10.60, which authorizes a written correction demand and referral to the city attorney for prosecution or injunction. Sec. 1-14 sets the forfeiture at $50.00 to $500.00 for a first offense and $100.00 to $1,000.00 for a repeat offense of the same provision, plus costs of prosecution.

Setback Rules

In the City of Milton's SR-7 single-family district, principal buildings must sit back 20 feet from the front lot line, 8 feet from side lines, 20 feet from the rear line, and 15 feet on a corner's street side, per the Chapter 78 bulk standards table.

Key details: SR-7 front setback: 20 feet minimum. SR-7 side setback: 8 feet minimum. SR-7 rear setback: 20 feet minimum. Corner-lot street side setback: 15 feet minimum. Attached garage offset: Max 10 ft ahead of house face.

Building within a required setback without an approved variance is enforced by the zoning administrator under Sec. 78-10.60, who can issue a stop-work demand and refer the case to the city attorney. Penalties follow Sec. 1-14: a first violation forfeits $50.00 to $500.00 plus costs, with jail up to 90 days for nonpayment; a repeat violation of the same provision runs $100.00 to $1,000.00, jail up to six months for nonpayment.
