Licensing
Arizona's Registrar of Contractors has no tree classification. The closest one it has is CR-21 Hardscaping and Irrigation, and that doesn't cover tree work.1
Tree removal permits
Cities and counties in Arizona set their own tree rules. Separately, the state's Native Plant Law requires landowners to notify the Department of Agriculture 20 to 60 days before destroying protected native plants on private land.2
Trees near power lines
If a tree is touching the power line to your house, keep clear and call your utility first. Clearing the line is the utility's job, and a tree company can't start until it's done.
In Arizona people and tools keep 6 feet from lines up to 50,000 volts and mechanical equipment keeps 10 feet, with more distance on lines above 50,000 volts. Anyone working closer must promptly notify the utility and agree arrangements with it first.3-4
811 and stump work
Spraying and treating trees
Pest management in ornamental shrubs and trees is licensed work in Arizona. Owners treating their own home are exempt.6-7
