Fence posts should generally be installed inside the property line to ensure that the fence is fully contained within your property. This is to avoid any potential disputes with neighbors over the placement of the fence.

Installing the fence posts on the inside of the property line makes it easier to maintain and repair the fence, as you can access all sides of the fence without having to enter your neighbor’s property.

Make sure to check with local regulations and zoning laws to ensure that you follow any specific fence placement requirements in your area.

In some cases, the placement of fence posts may be regulated by local ordinances, homeowner association rules, or other guidelines.
