Do You Need a Site Plan for a Fence Permit?

Published 2026-07-12 · Reviewed by Todd Hartman

Here is the short answer: where your fence needs a permit, the application almost always needs a site plan. And fences are the one project where the drawing is not really about a structure at all. It is about a line, and whether that line sits exactly where you claim it does.

A fence is a line, not a footprint

For a shed or a deck, the reviewer checks a box on your lot against setbacks. A fence review follows a route instead: which property lines the fence runs along, where it turns, where the gates go, and how tall each section is. That last part matters more than people expect, because nearly every city allows different heights in different yards, typically 3 to 4 feet in front and 6 feet in back and side yards, so a single height number rarely describes a whole fence. The plan labels the height run by run.

Corner lots add the sight triangle: a zone near the intersection, commonly measured 10 to 45 feet from the curb, where nothing over about 3 to 3.5 feet may block a driver's view. Reviewers check it on the drawing, and fences that ignore it are among the few that get ordered removed. The fence permit rules by state cover where permits apply at all, and the height thresholds are in our guide to how big you can build without a permit.

What the fence site plan has to show

The fence route, drawn along your property lines, showing which sides of the lot it covers
Height by section, one label per run, matched to your front and rear limits
Gates and openings, which matter for emergency access and pool enclosures
The sight triangle left clear, if you are on a corner
Pool barriers shown as a closed loop around the pool area, where that is the fence's job
Easements, the check that stops more fence applications than any other
The basics block: north arrow, scale, parcel number or address

The easement problem, specifically

Drainage and utility easements love the same real estate fences do: the strip along the rear and side lot lines. They are recorded on the subdivision plat, they are usually invisible on the ground, and a fence inside one can be rejected even where the height and placement are otherwise perfect. It is not a rare, theoretical failure: one of the three real correction notices we walk through in our approval-rate breakdown is exactly this, a Houston-area fence flagged for encroaching on a platted drainage easement along the rear line. The fix was drawing the easement from the recorded plat and pulling the fence to its edge, and the permit was issued the same week.

The lesson for your application: the plan needs to show easements of record, not just what you can see in the yard.

Getting the drawing

The drafted route: fence site plans run $89 to $259, delivered in 24 to 48 hours, with the route, section heights, and gates drawn to scale from county GIS and satellite imagery, easements of record included, and free revisions until your city accepts it.

The DIY route is workable for a simple lot: the six-step drawing walkthrough covers the method and the Pre-Submission Checklist is the quality gate. One fence-specific warning: never trace the existing fence as if it were the boundary. Old fences are famously off the line, and a new fence drawn from a wrong line inherits the problem in permanent form.

Before you dig

Check your city's checklist for local extras, like masonry fences or floodplain rules, and call 811 before setting posts so buried utilities get marked. It is free, and in most states it is the law. For everything else about the drawing itself, the complete guide to site plans for permits goes deeper on every item above.

Frequently asked questions

Do all cities require a site plan for a fence permit?

Wherever a fence permit is required, a drawing of the fence line is nearly always part of the application, because the whole review is about where the fence sits and how tall each section is. Some departments accept a simple marked-up plat for a like-for-like replacement, but new fences, front-yard fences, and pool barriers almost always need a proper site plan.

Can I build my fence right on the property line?

Rules differ. Some cities allow a fence directly on the boundary, often expecting your neighbor's agreement, while others require it to sit fully inside your line, sometimes by a set number of inches. Either way, the review works from your site plan, and building from the old fence line instead of the actual boundary is the classic mistake, since existing fences are frequently not on the line.

What does a fence site plan need to show?

The fence route drawn along your property lines showing which sides of the lot it covers, the height labeled for each run since front and back limits usually differ, gate locations, the sight triangle kept clear on corner lots, any easements the fence crosses or borders, and the basics block of north arrow, scale, and parcel number or address.

Do I need a site plan if my fence does not need a permit?

It is often worth sketching one anyway. Height limits, sight triangles, and easement rules apply to exempt fences too, HOAs usually want a drawing before approving, and a fence built into a drainage or utility easement can be ordered moved no matter how short it is. A five-minute placement check on paper is much cheaper than resetting posts.
