Fence Permits & Property Lines in Connecticut

Do I need a permit for a fence in Connecticut?

It depends on your town — and sometimes on the fence. Many Connecticut towns require a permit for fences over a certain height (often 6 feet), for fences in front yards, and for fences on corner lots, while allowing lower backyard fences without one. Some towns require a zoning compliance check even when no building permit is needed. The only safe answer is your town's zoning office, and a good contractor checks before quoting, not after digging.

Setbacks, height limits, and corner lots

• Front-yard fences are usually limited to 3–4 feet in most towns, and often must be open-style (picket or ornamental) rather than solid privacy.
• Side and rear fences are commonly allowed to 6 feet, sometimes 8 feet with a variance or special permit.
• Corner lots face sight-triangle rules: fences near the intersection must stay low enough that drivers can see around the corner. This catches more homeowners than any other rule.
• Setbacks from the property line vary — some towns allow fences on the line, others require a setback of a foot or more so the owner can maintain both sides. Building on the line without an agreement invites a dispute.

The survey question

If you have a survey or plot plan on file, your contractor can work from it. If you don't, and the line is uncertain — old stone walls, moved markers, a neighbor who disagrees — a new survey is worth every dollar. A fence built six inches over the line can cost thousands to move and poison a neighbor relationship for years. Get the line right before the first post hole, not after.

Neighbor fences and shared lines

Connecticut has no statewide rule forcing a neighbor to split fence costs, and handshake agreements about shared fences are a classic source of disputes. If a fence sits on a shared line, get the arrangement in writing: who paid, who maintains it, and what happens when it needs replacement. If the fence is entirely on your property, it is entirely your fence — and your responsibility to maintain.

Call Before You Dig

Every fence job in Connecticut starts with a utility locate — Call Before You Dig (811) — before any post hole is dug. Gas, electric, water, and telecom lines cross backyards in places no one remembers. A contractor who digs without a locate is a contractor to stop on the spot.
