It is generally not required in BC to build a fence, no law says you should divide neighboring properties. Most homeowners just want to. Some rules though do dictate what kind of fence is allowed and where it can be placed. There are a few instances where a fence is required (and fencers in British Columbia know this)

1. When your property has a swimming pool,
2. When you have a dog, the dog must be secured within a fence,
3. Some housing developments such as strata properties require fences to divide units

You cannot build on the common property line unless you mutually agree with your neighbor. If unsure about the property line, a fence contractor can do the land survey for you to determine the exact boundary.

If you and the neighbor mutually agree, then it is between the two of you on who will shoulder the expenses. It is highly advisable to put your agreement in writing. The best option however, it to build within your property so as to avoid any dispute in the future.

Keep in mind that should a dispute reach legal resolution, you are living next to each other and it is best to be on good terms.

There are local bylaws for every town and community in BC regarding the type of fence you can build. Before choosing what fence to build for aesthetic or security purposes, consult a licenced fence contractor in British Columbia who knows the bylaws.

For instance, a fence between properties must not have the type with an electric voltage nor barbed wire.

There are also zoning bylaws as to the height of the fence you can build. A typical example is your front yard fence cannot be higher than four feet, while side and back fences can be higher.
Then there are areas where owners of corner properties cannot build a fence that will obstruct incoming traffic view.

There are areas that do not. But some areas do need a building permit, and it is your fencing contractor who can assist you with this and provide more information. You can check Civic Info to be sure about the fence bylaws.

Also, it is illegal in BC to move the survey monuments of corners and property, while in the case of housing developments, there may be certain styles to follow, or not allow it at all.

Another thing to remember is to make sure that you are not hitting any water lines, septic lines, telecommunication and electrical lines. Best that you call BC One Call (for free) at 1-800-474-6886 before you dig to prevent any accidents while digging.

Maintenance of a fence is required in some city and town bylaws. If the fence is right along the property line, agree with your neighbor in sharing the mutual upkeep.
