DIY Fence Addition

Check local building and zoning codes to make sure you are in compliance with regulations that govern setbacks, easements and height restrictions. You might be subject to new regulations that took effect after your original fence was built.

Verify your property line. This may require engaging the services of a licensed land surveyor. It will be worth the expense to keep you from having to move your fence if you accidentally build it on your neighbor's property.

Talk with your neighbors. This is particularly important if you wish to tie onto an existing fence on their property. This can save you some money, but you need to get their permission first.

Measure the area you wish to contain that extends beyond your original fence. The type of fence you extend will determine the building materials you need to purchase.

Set your terminal posts, also referred to as corner posts, approximately 4 inches inside your property line to ensure you don't encroach on your neighbor's property. Set additional fence posts at regular intervals between the terminal posts and your existing fence. Terminal posts and fence posts that are set in concrete provide a more solid foundation than those that are driven into the ground. The interval will vary based on the type of fence you are installing. Install the fencing materials on the posts.
