Coconino County, AZ Landscaping Rules: Weed Ordinances (2026)

E splits its weed and grass rules into fire-safety defensible space standards and a separate weed-mitigation program. v requires grass be cut to a height no greater than 4 inches above ground level, ladder fuels removed, tree limbs trimmed at least 6 feet up, and vegetation treatment extended to 130 feet total on slopes over 20 percent. That standard applies to every subdivision and development inside the Wildland/Urban Interface that is required to carry a landscape plan; defensible space in all three zones must be maintained at least once a year.

2's Weed Mitigation program requires a qualified landscape professional to identify every Noxious Weed species on a development site before construction, remove existing weeds using direct removal or herbicide, and use only certified weed-free aggregate material. C requires annual monitoring for the reoccurrence of Noxious Weeds across the entire property, with control required using the same methods until the site is weed-free again, and it states plainly that the site must remain weed-free going forward. The Community Development Department can conduct a site visit to document compliance, and a waiver from the landscape-professional requirement is available only with the Community Development Director's approval.
