In unincorporated Mohave County the adopted property maintenance code, Ordinance 2021-03, caps weeds and rank vegetation at 30 inches. Kingman, Lake Havasu City, and Bullhead City run their own codes. The concern is fire fuel and blight, not tidy lawns.
Mohave County Ordinance 2021-03, IPMC Sec. 302.4
IPMC Section 302.4 Weeds: Amend to insert 30 inches into bracket.
No Mohave County ordinance requires a permit to prune or trim a tree on your own lot, and there is no urban street-tree program in the unincorporated desert. The real limit is Arizona's Native Plant Law, which protects wild species like saguaro, ocotillo, and ironwood.
Unincorporated Mohave County has no urban tree-removal permit for homeowners clearing their own yard. The rule that actually applies is Arizona's Native Plant Law, which requires advance notice to the state before clearing protected desert plants from raw land.
Mohave County treats overgrown weeds, dead vegetation, and rubbish as a public nuisance. The county can order abatement, clear the lot through a contractor, and assess the cost against the property. Dry desert brush and tumbleweeds are the real fire-fuel concern.
Mohave County Ordinance 2021-03 (nuisance abatement costs)
The cost of removal or abatement of the rubbish, trash, weeds, filth, debris or dilapidated buildings as determined by the invoice submitted by the contractor that removed or abated the public nuisance
Most of Mohave County sits outside any Active Management Area, so the strict groundwater-conservation and assured-water-supply rules governing Phoenix and Tucson do not apply. Household wells are largely unregulated, but the Hualapai Valley basin is a declared Irrigation Non-Expansion Area.
Rainwater harvesting is legal across Mohave County. Arizona places no state-level restriction on collecting rooftop rain, so barrels and cisterns for desert gardens and landscaping are allowed. In an arid county, captured monsoon runoff is a genuinely useful irrigation supplement.
In the Mojave Desert, gravel yards and native, drought-tolerant plants are the norm, and no county rule forces a grass lawn. Arizona's Native Plant Law protects wild desert species growing on the land itself, mostly at the land-clearing stage.
AZ Native Plant Law (A.R.S. Title 3, Ch. 7); Mohave County Native Plant Protection
Destruction of native plants on individually owned residential property of ten acres or less where initial construction has already occurred

the association may not prohibit installing or using artificial turf on any member's property
