Full Breakdown
Appleton's Zoning Ordinance fixes yard setbacks district by district rather than citywide. Sec. 23-92(g) sets the R-1A single-family district's space limits: an 8,000-square-foot minimum lot, 40% maximum lot coverage, 70-foot minimum lot width, a 20-foot minimum front yard (25 feet if the lot fronts an arterial street), a 25-foot minimum rear yard, an 8-foot minimum side yard, and a 35-foot maximum building height. The R-1B single-family district next door is denser: Sec. 23-93(g) drops the front yard to 10 feet (20 feet on an arterial), keeps the 25-foot rear yard, and cuts the side yard to 5 feet for single-family dwellings or 6 feet for other uses, with 75% maximum lot coverage.
R-2 two-family and the higher-density R-3, commercial and industrial districts each carry their own dimensional tables under Sec. 23-95 through Sec. 23-132, so the controlling number always depends on the parcel's zoning classification, which the Inspections Division can confirm from the official zoning map, Sec. 23-38. A separate rule protects older, undersized parcels: Sec. 23-42(f) lets a nonconforming lot of record be built on if its side and rear setbacks are reduced in proportion to how much smaller the lot is than the district minimum (rounding fractions up), though a side yard can never drop below 5 feet, and any front yard reduction must match the average setback of the abutting structures rather than the zoning table.
Violations & Fines
The Inspections Supervisor enforces Chapter 23 and can issue a municipal citation under Wis. Stat. § 66.0113 for building or expanding within the required setback. Because no specific zoning penalty is listed, the general penalty in Sec. 1-16 applies: a first offense carries a forfeiture of not less than $1.00 nor more than $200.00 plus costs of prosecution, and a second or later conviction for the same violation runs $10.00 to $500.00 per offense, with jail time in default of payment. A structure built into a required setback without a variance from the Board of Appeals under Sec. 23-67 is a continuing violation subject to a new citation each day it remains noncompliant.
