The depth of the fence posts depends on the height of your fence. If you’re installing a 6-foot fence, then digging 2-foot-deep holes for the fence posts will help ensure a secure installation. However, if you’re installing an 8-foot fence, the posts will need to be deeper than 2 feet to support the structure properly. Also, consider how far apart the fence posts should be to provide adequate support.

Whether you need a permit to build or install a fence depends on several factors, including your location, the fence's height, its placement in your yard, and the materials used. In many cities and highly populated areas, a permit is required, especially for fences taller than 6 feet. Conversely, rural areas may have fewer restrictions. Typically, backyard privacy fences 6 feet or shorter do not require a permit, while front yard fences often have a lower height limit, sometimes as low as 3.5 feet. There can also be exceptions for properties in mixed residential-commercial zones. It's best to check with your local building inspection or zoning department to understand the specific requirements, height restrictions, and location rules for your area. A professional fence installer can help you navigate this process and often secure the necessary permits for you, though this may extend the project timeline.

How long a wood fence lasts depends on the type of wood and its style. The design of a shadow box fence makes it more durable than other fence types because the alternating pickets disperse the weight across the rails. As a result, you won’t have to worry as much about sagging or failing pickets. However, remember that the hollow design of a shadow box fence makes it more difficult to apply the sealer, which is crucial to extending its life.
