Full Breakdown
270 establishes the 'A' Agricultural District to preserve and protect land valuable for agriculture and open space from non-agricultural activity, and states plainly that the district is not intended for low-density residential subdivision. 270(C). 270(D)(1)(a), while a farmhouse is capped at two and one-half stories and thirty-five feet at the eave, and other accessory buildings are held to one story and a fourteen-foot sidewall, sixteen feet with sealed engineered drawings. Setbacks in the district run fifty feet from the road right-of-way on the front, twenty-five feet on the side, and fifty feet on the rear, and a lot with frontage on two roads needs a front setback on both.
Minimum lot size is twenty acres with at least four hundred feet of width at the road frontage or building setback line. 270(F): a single-family residence built as a farm residence on five contiguous acres or more before February 1, 2005 can keep operating as Rural Residential without meeting the twenty-acre and lot-width standards that apply to new agricultural residences.
Violations & Fines
Cass County Code § 400.270 carries no violation-specific fine, so exceeding the two-residence cap, building on an under-sized tract, or violating a setback in the Agricultural District falls under the Code's general penalty, § 100.210: a civil penalty of up to $1,000, with every day the violation continues counted as a separate offense. The Cass County Zoning Officer and Board of Zoning Adjustment handle enforcement and any appeal.
