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.

Both nails and screws are common in fence construction, including on pickets. Some builders prefer to use nails when connecting the pickets to the rails and screws when connecting the rails to the posts. However, the best option usually depends on the type of wood fencing and the variety of wood you choose.

A fence post set in concrete lasts anywhere from five to over 25 years, depending on how well the concrete was applied and the fence post’s material. Untreated wood posts in concrete could last less than 10 years, but a durable, treated wood set in properly applied concrete could last a few decades. However, all fence posts will wear out eventually, so expect to need to replace your fence post every five to 15 years.

If you’re looking for a budget-friendly fence material, corrugated metal could be the answer. Metal fences cost about $7 to $32 per foot. Aluminum corrugated metal tends to be less expensive than steel. Both options are similar in cost to wood, so, depending on the type of wood you are considering, corrugated metal could be better for your budget.
