Retaining walls over 4 feet measured from bottom of footing to top of wall require a building permit and engineered plans throughout Dane County under the Wisconsin UDC and DSPS SPS 321. Madison (MGO §29.07), Fitchburg, and Middleton require permits at lower thresholds if surcharged.
The Wisconsin Uniform Dwelling Code (Wis. Admin. Code SPS 321.02) and Commercial Building Code (SPS 361) require building permits for retaining walls exceeding 4 feet in height or any wall supporting a surcharge (driveway, structure, or sloped soil). Madison Building Inspection under MGO §29.07 issues permits and requires stamped drawings from a Wisconsin-licensed professional engineer (Wis. Stat. Ch. 443) for walls over 4 feet or any surcharged wall regardless of height. Fitchburg Code §26-198 mirrors this, as do Middleton, Verona, Sun Prairie, and Stoughton. Dane County Zoning (Ch. 10) enforces the same standards in unincorporated areas. Setbacks from side and rear property lines typically match accessory-structure setbacks (3 to 5 feet). Drainage must be addressed under UDC and IBC 1807 with weep holes or drain tile. Walls within Yahara watershed, Lake Mendota/Monona shorelands, or FEMA Special Flood Hazard Areas trigger Dane County Shoreland Zoning (Ch. 11) and Wis. Stat. §59.692 review.
Unpermitted walls over 4 feet: Madison stop-work order MGO §29.07, double permit fees, and possible demolition. Forfeitures $200 to $1,000 under MGO §29.21. Engineering review required retroactively. Dane County Ch. 10 Zoning fines start $500 plus daily continuing violations.
