Milwaukee County has no retaining-wall ordinance for private land. Wall permits, height thresholds and engineering requirements are set by each incorporated city or village, so check your municipality's building code.
Because Milwaukee County does not regulate private construction, retaining-wall rules come from your municipality. Most Wisconsin cities and villages, following the state building code, require a permit and engineered plans once a wall exceeds a set height (commonly 4 feet measured from the bottom of the footing). Walls that support a surcharge or a slope may need a permit at lower heights. Contact your city or village building or inspection office for the exact threshold, setback and drainage requirements that apply to your lot.
Building an over-height retaining wall without the required municipal permit or engineering can bring a stop-work order, corrective engineering, or an order to rebuild. Penalties are set locally.
