9 rules for unincorporated Pinal County, Arizona.
Verified from official government sources
Pinal County sets no numeric lawn-height limit for unincorporated desert lots. Instead, overgrown "weeds" that become a public nuisance must be cleared within 30 days of a county Notice to Abate. Cities like Casa Grande and Maricopa set their own turf rules.
Pinal County has no general residential tree-trimming ordinance for private yards. The main county rule is that vegetation must stay clear of sight-visibility triangles at intersections (21'x21' local, 33'x33' others) and not obstruct county roads or rights-of-way.
For ordinary (non-protected) trees on unincorporated Pinal land you generally need no county tree-removal permit. But protected native desert plants such as saguaro, ironwood, and palo verde are governed by Arizona's Native Plant Law and may require notice or a permit before you destroy them.
A.R.S. 3-904(H)
This section does not apply to the destruction of protected native plants on individually owned residential property of ten acres or less where initial construction has already occurred.
In unincorporated Pinal County, owners and occupants must remove rubbish, trash, weeds, filth, debris, and dilapidated buildings that are a public nuisance within 30 calendar days after a Notice to Abate served by Development Services. "Weeds" means all vegetation growing on streets or private property.
Pinal County Development Services Code, Title 12 (Nuisances); Ord. 2024-PZ-C-002-24
The owner, lessee, or occupant shall remove rubbish, trash, weeds, filth, debris, or dilapidated building or otherwise abate a public nuisance within thirty (30) calendar days after service of a Notice to Abate.
Pinal County has no county-wide day-of-week outdoor watering ban, but most of the county sits in the Pinal Active Management Area under state groundwater law. ADWR meters and reports non-exempt wells, and has declared groundwater cannot support new subdivisions relying on it.
Rainwater harvesting is legal statewide in Arizona and Pinal County imposes no ban. Outdoor barrels and cisterns for irrigation need no permit. Only systems that pipe rainwater indoors for potable or non-potable plumbing must meet state building-code sections.
Arizona's Native Plant Law protects wild desert plants across Pinal County. Moving or salvaging a saguaro over four feet tall requires a permit, tag, and seal from the Department of Agriculture. Highly safeguarded species like saguaro have the strongest protection statewide.
A.R.S. 3-906(A)
A person who moves or salvages a saguaro cactus (cereus giganteus) that is more than four feet tall, from other than its original growing location, must purchase a permit, tag and seal from the department.
Pinal County does not ban artificial turf, and Arizona state law bars HOAs from prohibiting it. In any planned community that allows natural grass, associations may not stop owners from installing artificial turf, though reasonable appearance rules are permitted.
A.R.S. 33-1819(A)
the association may not prohibit installing or using artificial turf on any member's property.
Pinal County has no ordinance banning residential backyard composting. The limit is the county nuisance code: a compost pile that produces odor, attracts vermin, or becomes filth or debris can be ordered abated as a public nuisance within 30 days of notice.
