Your wooden gate post hole should be a third to a half of the height of the post. Also, note that the diameter of the post hole should be three times the diameter of the post. You should set the post in concrete to ensure a long-lasting and durable post that will withstand the test of time.

You’ll need to bury the garden fence about 1 foot underground. It’s tempting to save on materials by burying the fence just a couple of inches, but if you do so, determined pests will still be able to dig under the fence and access your plants. Burying your garden fence deep into the soil is an important step that allows you to attach a wire barrier to the fencing. 

Burrowing animals (like voles, moles, rabbits, and gophers) can’t dig or chew through this wiring, meaning that you’ll be keeping your prized petunias or your robust veggie garden from being eaten.

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.

Most homeowners don't need to inform their neighbors before constructing a fence, according to the law, but you will need to make sure that you’re building on the property line or on your side of the property line. Otherwise, the neighbor could complain, which would require you to tear down and reinstall the fence. In any case, keeping them in the loop is the neighborly thing to do!

Whether you inform your neighbors or not, always use property records and a land survey to ensure your fence stays within your property boundaries.
