The cheapest farm fences are typically wire fences, which cost less to install than traditional lumber fences. Barbed wire is one of the most inexpensive options due to its simple materials, making it a good choice for low budgets. It is suitable for confining docile animals in large spaces, as it provides a visual barrier and a mild deterrent. Other options like hog wire and woven wire fences are also cost-effective because they require less lumber than a full wooden fence. These types of wire fences are strong, long-lasting, and relatively easy to repair, though they are often considered less aesthetically pleasing than wood.

Removing fence posts that are set in concrete is something you can't do by hand. You will need an excavator, a strong post-puller, or a jackhammer. If you plan on recycling the concrete base, you may be able to cut the post out with a jackhammer and then set the new post in the existing base. However, it's usually better to remove both the fence post and concrete together. Due to the weight of concrete, you will need a hydraulic removal tool.

Split rail fencing is a type of post and rail fencing. Other post and rail fences include corral board and post and dowel. Post and rail fencing is the term used for any type of fence with vertical posts, horizontal rails, and nothing else (specifically excluding pickets). So, technically, a split rail fence is a post and rail fence.

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.
