You can't build a fence against your neighbor's fence if it touches or is attached to it unless you get explicit permission from your neighbor. Most municipalities recommend building a fence about two feet away from your neighbor's fence to allow access for fence repair and mowing.

Most people prefer to keep the fence level by “stepping” the fence when running a horizontal fence over a slope. Stepping involves raising each panel between the posts as the fence moves over changes in slope, giving the fence line the appearance of stair steps. While this may be the preferred method of running a horizontal fence up a slope, there’s nothing wrong with installing your fence so it follows the undulations in the ground instead.

The legal implications of installing barbed wire fencing will vary from city to city. You should check your local regulations to see if barbed wire fencing is allowed, and what restrictions exist. For instance, some municipalities might require that your fence be a certain height and a certain distance from your home.

A fence installer or homeowner should place a snow fence upwind of the desired drift area, while keeping the prevailing wind direction in mind. When installing a snow fence, its posts should be sturdy, as they will be the weakest areas in terms of tensile strength. Posts should be buried at one-third their height and placed no more than eight feet apart.
