Full Breakdown
D of the Coconino County Zoning Ordinance sets Lot Coverage, maximum, at 30% for the General (G) zone and 35% for both the Agricultural Residential (AR) and Rural Residential (RR) zones. Lot Coverage is measured against the same table's other minimums for the parcel: a 10-acre minimum net parcel size in G against 1 acre in AR and RR, a 300-foot minimum Lot Width in G against 100 feet in AR and RR, and a 300-foot minimum Lot Depth in G against 150 feet in AR and RR.
The table pairs the coverage cap with a Structure Height maximum of 40 feet in G and 35 feet in AR and RR, so the two limits work together to control both footprint and bulk on a parcel. Every Setback, Front, Side Interior, Side Street Side, and Rear, is also measured from the property line under Note 2 to the table, and where an Access Easement runs along that line the Setback is measured from the Easement's interior edge instead. 11 before any building permit is issued to confirm that a proposed Structure, together with any accessory buildings on the same parcel, stays within the applicable coverage percentage for its zone.
Violations & Fines
Exceeding the Table 2-1 coverage cap is enforced as a zoning violation under Section 5.14.C.4.A. A Deputy Zoning Inspector can cite the property, the county can withhold further building and zoning permits until the excess coverage is removed or approved by Variance, and a Hearing Officer can levy civil or criminal fines up to $750 per day for an individual or $10,000 per day for a business, escalating to the County Attorney once daily penalties pass $1,500 on a residential parcel.
