Arborists and Tree Contractors

The City of Boulder has an arborist licensing program for tree care contractors doing work on both public and private property within Boulder city limits.  

The City of Boulder started the licensing program for several reasons:  

  • To ensure all persons/ companies performing tree work within the city have the necessary insurance;  
  • To ensure all tree work within the city is performed in a safe, professional manner and according to industry standards;  
  • To ensure all diseased/infested wood is disposed of in a proper manner to prevent the spread of insect/disease problems; and  
  • To maximize environmental, social, economic and health services derived from the Boulder urban forest.
