Coconino County, AZ Building Setbacks & Zoning: Lot Coverage Limits (2026)

Item 10 of Table 2-1 in Section 2.2.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. The development standards apply only as a minimum; the Community Development Director conducts plan review under Section 1.11 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.
