What is the Fence Ordinance in Knoxville Tennessee?

If you’re planning to build a fence in Knoxville, Tennessee, it’s crucial to understand the local fence ordinance before you dig a single post hole. Following these rules doesn’t just keep you legal, protect your property value, your neighbors’ safety, and your own peace of mind.

Here’s what you need to know.

Property Lines and Fence Placement

No fence placed on any lot shall extend over the property line. That means your fence must sit entirely on your own property, not even an inch over. This is one of the most common sources of neighbor disputes, and it’s completely avoidable if you verify your property boundaries first.

The frame of the fence, including supports, rails, and posts must be placed on the inside of the fence. In other words, the “finished” or “good” side should face outward, toward your neighbor or the street, while the structural elements face inward toward your yard. This creates a cleaner appearance for the community and can help you avoid complaints.

Safety must be maintained on corner lots and near fire hydrants. On a corner lot a fence shall not obscure a clear view of traffic at intersections or driveways or create a safety hazard to pedestrians or vehicle traffic.

A fence cannot block visibility or access to any fire hydrant from the street. Firefighters must be able to see and reach hydrants immediately in an emergency. If your fence interferes with that, you’ll be required to modify or remove it.

Designing with these rules in mind from the start is far easier than being forced to redo your fence later.

Fence Height Limits in Residential Zoning Districts

In Knoxville’s residential areas, the ordinance sets straightforward height limits. For side and rear yards fences up to seven feet (7′) in height are permitted. For front yards, the maximum height is four feet (4′).

This balance allows you to enjoy privacy in your backyard while keeping front yards open enough to maintain neighborhood character and visibility.

Allowed and Prohibited Fence Materials

The city of Knoxville wants fences to be both durable and visually appropriate. Allowed materials include Chain-link, Wood, Polyvinyl chloride (PVC), Wrought Iron, Aluminum, Ornamental Woven Wire. and Welded Wire Mesh. These are commonly used materials that tend to be sturdy, safe, and reasonably attractive when properly installed and maintained.

Prohibited materials include Sheet Metal, Chicken Wire, Temporary Construction Fencing, Snow Fencing, or other similar materials not intended for permanent fencing

These materials are often unsightly, flimsy, or simply not designed for long‑term residential use. Using them for a permanent fence can lead to code violations and forced removal.

No Harmful or Dangerous Fence Designs

The ordinance is explicit about safety: No fence may be designed to cause harm to humans or animals. That means: no spikes, barbed wire, razor wire, nails protruding from the fence, or electrical charge fences.

Knoxville requires you to choose solutions that don’t physically endanger people or pets. Violating this rule can create serious legal and liability issues.

Construction and Maintenance Standards

Your responsibilities don’t end once the fence is built. The city requires that all fences shall be constructed in a sound and sturdy manner and shall be maintained in a good state of repair.

That means posts should be properly set and stable, panels and boards should be secure, not loose or falling, damaged or rotting sections should be repaired or replaced promptly, and rust, sagging, or broken parts should not be ignored.

A fence that’s poorly built or allowed to deteriorate can be considered a nuisance and may draw complaints or enforcement actions. Keeping your fence in good shape protects your investment and keeps your property looking cared‑for.
