Before you build a fence, you should have a survey done of your property. This will ensure you place your fence along the edge of your property, but also completely on your property. You should also check local laws to ensure there aren’t restrictions on where you can build your fence. These sometimes dictate how close your fence can be to sidewalks. You also need to check for utility lines. You don’t want to start digging a post hole and discover you’ve cut wires or a pipe.
