Summary
Land zoned Agricultural (AG) in unincorporated Jackson County cannot cover more than 15 percent of a lot with impervious surface. Exhibit 240.8 of the Unified Development Code, referenced in Jackson County Code § 24004.2(f)(1), sets that ceiling alongside the district's minimum lot size and lot width standards for buildings, driveways, and parking areas.
1. Development in the AG district shall meet the standards established in Exhibit 240.8 in addition to the standards established in other sections of the UDC. Exhibit 240.8: AG District Design Standards Minimum lot size (1) 10 acres ... Minimum lot width 250 feet Maximum impervious cover 15% (1) Except as otherwise provided in the above district regulations. (2) Silos and other agricultural structures may be constructed to the height of up to 55 feet provided that they are located a distance equal to or greater than their height from all property lines.
Full Breakdown
" That exhibit, titled "AG District Design Standards," caps Maximum Impervious Cover at 15%, the only percentage-based figure in the table, alongside a 10-acre minimum lot size and a 250-foot minimum lot width for AG-zoned parcels. A footnote to the exhibit clarifies the standards apply "except as otherwise provided in the above district regulations," and a second footnote allows silos and other agricultural structures to reach up to 55 feet in height if they sit back from every property line by a distance equal to or greater than their own height.
The same Development Performance Standards subsection also prohibits open storage in the AG district except for farm machinery, farm products, and temporary storage of road materials, and requires animal enclosure areas (pens, corrals, kennels, aviaries and similar confinement areas) to sit at least 50 feet from any property line, excluding grazing areas for horses, cattle, or other livestock. Because AG parcels run a minimum of 10 acres, the 15% impervious cap still permits well over an acre of hard surface on a minimum-size tract, but it caps site coverage as a fixed share of whatever the lot's actual size is. This record grounds only the AG district figure; other UDC zoning districts publish their own separate design-standard exhibits.
Violations & Fines
Exceeding the 15% impervious cover cap, or otherwise failing to meet Exhibit 240.8's AG Development Performance Standards, is a County ordinance violation under Jackson County Code § 24001.12. A conviction carries up to one year in the county jail or a fine of not more than $1,000, or both, with each day of a continuing violation counted as a separate offense; the Director's office enforces the standard, and the County Counselor may seek an injunction against noncompliant construction.
