Trees on private property are regulated by the Tree Management Bylaw 4091, 2010.
Important points to remember:
The City of Coquitlam does not regulate the trimming of trees on private property as long as the trimming does not violate the City’s tree management bylaw, notably ‘damage to a protected tree’.
Urban Forestry strongly recommends speaking with your neighbor before beginning any tree work. As always, it is recommended that an ISA certified arborist perform any tree work.
The City of Coquitlam does not regulate the trimming of trees on private property as long as the trimming does not violate the City’s Tree Management Bylaw.
Urban Forestry recommends that you discuss this with your neighbour prior to planning any tree work. There are three main points to remember when dealing with trees on adjacent private property:
It is, therefore, best for property owners to come to an agreement between themselves with respect to trees overhanging property lines. This is not something that the City can be involved in. If you are unable to reach an agreement with your neighbour and want to determine your legal rights, you should contact a lawyer. If you choose to prune a neighbouring tree:
You cannot top the tree (or any tree in Coquitlam) or raise the crown excessively as this is also a violation of the Tree Management Bylaw.
If you are concerned that a tree on a neighbouring property is putting your property at risk or has the potential to cause property damage, advise the property owner so that they may take the required action to address the situation.
Maintenance of privately owned trees is the responsibility of the property owner and issues regarding neighbouring trees are a matter between neighbours. Discussion and resolution is recommended. This is not something that the City can be involved in. If you are concerned about the safety of the trees you may wish to discuss the hiring of a "qualified tree risk assessor" with your neighbour.
