Navajo County, AZ Building Setbacks & Zoning: Setback Rules (2026)

Section 503's Development Standards table governs the two Single-Family Residential Districts side by side. R1-43, the 43,000-square-foot-minimum district, carries a 100-foot minimum parcel width, 20% maximum lot coverage, and 20-foot front, 20-foot rear and 20-foot side yard setbacks. R1-10, the 10,000-square-foot-minimum district, allows denser development with a 60-foot minimum width, 30% lot coverage, the same 20-foot front and rear setbacks, but a narrower 10-foot side setback. Both districts also require at least 5 feet of separation between buildings on the same lot and cap building height at 30 feet.

The A-General district applies looser numbers instead: Section 303 sets a 20-foot front, 20-foot rear and only a 10-foot side setback on a minimum one-acre parcel, with a footnote allowing parcels under an acre if the soil passes a percolation test of 120 minutes per inch or the parcel has sewer access. The Multi-Family R districts tighten the side setback further: Section 603 sets the R-2 side yard at just 5 feet. Because these setbacks are printed per district rather than county-wide, confirming a project's zoning district before measuring is the first step; the Planning and Zoning/Community Development Department can confirm a parcel's district and applicable setback table on request.
