Full Breakdown
The Kenai Peninsula Borough has no borough-wide zoning ordinance, so lot-coverage limits exist only inside a Local Option Zoning District (LOZD) that property owners have petitioned the assembly to form under KPB 21.44.030. In a Single-Family Residential (R-1) LOZD, KPB 21.44.160(C)(4) limits maximum coverage by structure to 20 percent of the lot, a standard that applies alongside the district's minimum 40,000-square-foot and maximum 5-acre lot sizes under subsection (C)(3), its 30/20/15/50-foot setbacks under subsection (C)(1), and its retained natural-drainage requirement under subsection (C)(5). Coverage is calculated from all principal and accessory structures on the parcel, including the garages, sheds, workshops and single guesthouse allowed under subsection (C)(6).
Other LOZD types adopted elsewhere in the borough, including the Small Lot Residential (R-2), Residential Waterfront (R-W) and Multi-Family Residential (R-M) districts, carry their own separate coverage percentages rather than the R-1 figure. Outside an adopted LOZD, and outside the cities of Kenai, Soldotna, Homer, Seward, Seldovia and Kachemak, no borough ordinance limits how much of a lot a structure covers. The Planning Department reviews development notices under KPB 21.44.135 and enforces coverage compliance for lots within formed LOZDs.
Violations & Fines
Exceeding the 20 percent coverage cap in an R-1 LOZD is a Development Standards violation of KPB 21.44.160(C), fined $300 per day under the KPB 21.50.055 fine schedule; each day of the overbuilt condition is a separate offense under KPB 21.44.150. The borough can also bring a civil action seeking removal or alteration of the noncompliant structure and damages under KPB 21.50.040(A), or a civil penalty up to $1,000 per day in an administrative proceeding under KPB 21.50.040(B).
