A horizontal fence is typically more expensive to build than a vertical fence, often costing between 10% and 20% more. The higher cost is due to the need for a higher grade of lumber and more posts to prevent the boards from sagging, which increases both material and labor expenses. Despite the higher price, horizontal fences tend to be more durable and offer a more distinct, modern look compared to the more common vertical picket style. However, they may not be the best option for privacy, as there can be slight gaps between the horizontal rails.

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.

Posts for a horizontal fence should be no more than 6 feet apart. Wood pickets are not as strong when mounted horizontally as when mounted vertically. As such, the fence panels on a horizontal fence can’t cover the same span between posts as a vertical fence can. If you install the posts further apart on a horizontal fence, the fence will lose stability, making the boards more likely to sag. 

Hedges are a better financial investment for a home than fences in several ways. First, hedges are less expensive to install than fences. Fence installation costs $1,775 to $4,600, depending on the type and size. You can also choose to plant smaller and less expensive hedges, knowing that it will take longer for them to mature. Next, mature hedges add resale value to the home, meaning the cost savings get even better when it's time to sell.
