Fence height rules in Bath, Maine
Yes. Under Bath's new Land Use Code, fences can go in any setback or on the lot line, but in a front yard (or the street side of a corner lot) a solid fence can be no taller than 4 feet, while an open fence has no height limit; the code sets no height limit for side and rear yards. The new code doesn't mention a fence permit; the Codes Office's 2019 handout says only fences over 7 feet need one, so confirm with the office.
| Solid fence, front yard or corner side yard | 4 ft max [2] |
| Open fence, front yard or corner side yard | No height limit [2] |
| What counts as an open fence | More than 70% of the surface is evenly spaced openings [3] |
| Location | Any setback or along a lot line, with room left for maintenance [1] |
| Corner sight triangle | Nothing blocking views 3 to 10 ft above the street within 20 ft of the intersection [5] |
| Permit threshold (2019 Codes handout; not in the new code) | Fences over 7 ft [6] |
| Maintenance gap from lot line (handout guidance) | Usually 1.5 to 2 ft [7] |
| Retaining walls | Over 4 ft must be designed by a registered professional engineer [9] |
Height and placement
Bath's new Land Use Code (in effect since September 23, 2026) lets you put a fence or wall in any setback or along a lot line, as long as there's room to maintain it [1]. In the residential and commercial districts, fences in the front yard, or in a corner side yard between the front building line and the front lot line, follow two rules: open fences have no height limit, and solid fences are capped at 4 feet [2]. An open fence has more than 70% of its surface in evenly spaced openings. A shadowbox fence counts as solid, but a chain link fence with slats does not [3]. The code sets no fence height limit for side and rear yards. Fences aren't "structures" under the code's definition [4], so the accessory-structure setbacks don't apply to them.
Corners and driveways
Every fence must meet the corner clearance rules [2]. On a corner lot, nothing may block vision between 3 and 10 feet above the street within the triangle formed by the pavement edges and a line joining points 20 feet from the intersection [5]. A smaller 5-foot triangle applies where a driveway meets a street. The Codes Office's fence handout adds a driveway sight-distance rule: 10 feet of sight distance for every mile per hour of posted speed, assuming 25 mph if unposted [8].
Permits and practical rules
The new Land Use Code doesn't say whether a fence needs a permit, and its building-permit rule covers buildings and structures, which by definition exclude fences [4]. The only permit rule we found is in the Codes Office's April 2019 fence handout, written under the old code: fences over 7 feet high need a permit, using the building permit form with a site plan [6]. Confirm with the Codes Office that this still applies. It recommends setting fences back far enough to maintain them without going onto the neighbor's land, usually 1.5 to 2 feet [7]. The land near the street or sidewalk is often City right-of-way, and a fence there needs Public Works approval. If you're within 15 feet of a fire hydrant, review the plan with the Fire Department. Retaining walls taller than 4 feet must be designed by a registered professional engineer [9].
Outdated handout parts
The handout dates from April 2019 and cites the old code's section 11.11. Its corner rule (3 feet max within 20 feet) and retaining-wall rule (over 5 feet) are replaced by the new code's §9.1.D and §9.7.D.

Next steps
- Find your front lot line (often set back from the sidewalk or street) and decide whether your fence will be open or solid.
- In the front yard or the street side of a corner lot, keep solid fences to 4 feet; open fences can be taller.

- If the fence will be over 7 feet, apply for a building permit at the Codes Enforcement Office (55 Front Street, 207-443-8334) with a site plan showing the fence location.

Maine state fence laws
Maine has no statewide fence height or setback limit. Those come from your town's zoning. A few state laws still apply:
Spite fences (17 M.R.S. §2801): A fence, or anything that works like one, that is unnecessarily taller than 6 feet and is maliciously kept up to annoy the neighbors is a private nuisance. The neighbor can take legal action over it.
Boundary fences and fence viewers (30-A M.R.S. §2951 and following):
- A "legal fence" is one 4 feet high and in good repair, made of rails, timber, stone, iron or wire, or the equivalent as judged by fence viewers.
- When both neighbors' land is enclosed and in use, they share upkeep of the dividing fence equally.
- If one side won't repair their share, the other can call in the town's fence viewers. The viewers can order repairs within up to 30 days. If the repairs still aren't made, the neighbor can do the work and recover double the cost.
- These rules mostly matter for farm and pasture fencing.
Shoreland zone: The DEP's model shoreland ordinance doesn't count fences as "structures," so the water setbacks for buildings don't apply to them. Limits on clearing vegetation near the water still do.
Pools: Pool barrier requirements are covered on the Pools page.
