City and county ordinances determine if a homeowner can build a fence along his own property line. In a gated community or subdivision, homeowners must also check the Home Owner Association guidelines in terms of fencing regulations.
Some ordinances have specifics about how to place the fence, such as placing the nice, finished side of the fence towards the street or neighbor's house. Some counties have height limits on fences, such as 4 feet for front-facing fences and 6 feet for side and back-facing fences. If building an artificial fence is not an option, consider a green fence. A green fence uses trees, shrubs and bushes to create a natural property division and add additional privacy to a home.
