Fence Rules in Allen, TX: What the City’s Guideline Says
Read from the City of Allen’s Residential Fence Guideline, dated June 2026. Where that document is silent, this page says so and gives the city’s phone number.
The Rules in One Table
| Subject | What the city guideline says |
|---|---|
| Height, back and side yards | Maximum fence height of 8 feet. |
| Materials | Acceptable fence materials are brick, wood and wrought iron. |
| Posts | All fencing requires metal posts; metal caps and hardware are required. Posts must be placed 18 inches deep in concrete. |
| Fence on a retaining wall | Allowed, with a maximum fence height of 8 feet. The wall and fence together may be no higher than 12 feet. |
| Pool or hot tub enclosure | Not less than 4 feet high, with self-latching and self-closing gates. The latch goes on the pool side, at least 4½ feet from the ground. |
| Easements | Fences in drainage, utility, water or sanitary sewer easements are not permissible without the express permission of the Engineering Department. Fences are customarily allowed in the standard 3-foot lot line drainage easement. |

City of Allen, Residential Fence Guideline, dated June 2026, read October 5, 2026. Published by Building and Permitting, 305 Century Parkway, Allen, TX 75013, 214.509.4130. The table paraphrases closely; the city’s document governs.
What the Guideline Does Not Settle
This site read the guideline and the city’s permitting pages and could not find these answers in writing. They are listed so you know what to ask.
- Whether a repair needs a permit. No threshold in feet, posts or percent of the fence appears in the guideline.
- The permit fee. Not stated in the documents read.
- Front yard fences. The guideline’s height figure is for back and side yards. The Allen Land Development Code has its own fence section, which this site was not able to open and read directly.
- Which side faces out. Nothing in the guideline says the finished side must face the street or the neighbor.
- Stain color. Not addressed by the city. Associations often do address it.
One call answers most of these: City of Allen Building and Permitting, 214.509.4130, weekdays 8 a.m. to 5 p.m. A fence contractor who works in Allen regularly will also know current practice, but the city’s answer is the one that counts.
Why the Post Rule Matters for a Repair
Most fence repairs come down to posts. A wooden post rots at the ground line, where it stays damp, and a rotted post lets the whole section lean. The guideline’s requirement for metal posts set in concrete means the lasting repair for a failed wooden post in Allen is a steel one.
Steel posts also make the next repair simpler. Rails attach to them with brackets, so rails and pickets can be changed in a decade or two without digging.
See leaning fences and posts for how that repair goes.
Pools, Creeks and Corner Lots
Pools
The pool figures are safety rules: a barrier at least 4 feet tall, gates that swing shut and latch on their own, and a latch on the pool side no lower than 4½ feet. A gate that has sagged until the latch misses its catch is a failed barrier, whatever the rest of the fence looks like. Gate repair and pool latches.
Lots that back to a creek or greenbelt
Several Allen communities are built along creeks. The floodplain and easement lines in the guideline apply to those back lot lines, so ask the city where the floodplain boundary sits on your lot before replacing a fence there.
Corner and alley lots
The visibility lines limit what can stand near an intersection or where an alley meets a street. If your fence was built before a rule changed, ask the city whether a replacement must move.
Before Anyone Digs
Texas811 says Texas law requires homeowners, as well as excavators, to contact 811 two business days before digging, not counting weekends and holidays, even in their own backyard. The request is free and can be made by calling 811 or online. Utilities then mark their lines. Post holes are digging.

Rules Questions
How tall can a backyard fence be in Allen?
The City of Allen’s residential fence guideline gives a maximum fence height of 8 feet in back and side yards.
Do I need a permit to repair my fence in Allen?
The city publishes its fence guideline among its permit forms and tells owners to check with their HOA before applying for a permit, so a permit process exists. The document this site read does not say whether a repair of a few posts or panels needs one. Call Building and Permitting at 214.509.4130 before work starts.
Can I rebuild with wooden posts?
The guideline says all fencing requires metal posts, with metal caps and hardware.
Can my fence cross the drainage easement at the back of my lot?
The guideline says fences in drainage, utility, water and sewer easements are not permissible without the Engineering Department’s permission, notes that fences are customarily allowed in the standard 3-foot lot line drainage easement, and says no fence of any kind is allowed in a floodplain.
Does my HOA get a say?
If your deed restrictions require approval for exterior changes, yes. The city’s own guideline tells owners, in capital letters, to check with their homeowner’s association before applying for a permit.
