What if my neighbour doesn’t agree to building a fence?
If you want to build a fence along the property line, you can do so only if the owner of the adjacent property agrees. It makes no difference if you intend to pay the total cost.
If your neighbour doesn’t agree, your best bet is to build the fence so that it falls entirely on your side of the property line. As such, it’s especially important that you accurately locate the property line. (See “What you should know,” above.)
Can I replace the fence that runs along my property line?
If you intend to remove or alter an existing fence along a property line, you must have either your neighbour’s agreement or a court order.
A fence built on the property line belongs to both property owners. You are jointly responsible for the upkeep of the fence. Neither can take it down without the other’s permission.
