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.
If you already know you need the drawing, a fence site plan is drawn to your lot from county records and delivered in 24 to 48 hours from $89, with free revisions until your city accepts it. The rest of this page is what the reviewer checks, and the two things that get fences torn out.
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.
Fence height requirements, by the numbers
Height is the thing zoning codes actually regulate, and the pattern across the 250 city records behind our state guides is much tighter than "check locally" implies:
- Front yard: 96% of the 199 cities with a numeric limit cap the fence at 4 feet or lower. 152 of them land on exactly 4 feet, 27 on 3 feet. A 6-foot fence across the front of a lot is unusual enough that it almost always needs a variance.
- Side and rear yard: 85% of the 232 cities with a numeric limit allow exactly 6 feet. Twenty allow 8 feet, ten sit at 7.
- At the state level, 24 of our 51 guides describe a 6-foot line as the common permit trigger and 20 describe a 7-foot line.
The practical consequence is that a typical suburban lot has two different legal fence heights on it, and the boundary between them is not the fence corner, it is where your front yard legally ends. On a corner lot there are often three. This is why a single height figure never describes a whole fence, and why the drawing labels it run by run.
Your local building department publishes the numbers that actually bind at your address, and the fence permit rules by state collect the state-level patterns.
What counts as your front yard
More fence corrections come from this definition than from the height numbers themselves. The front yard is usually measured from the front property line to the front face of the house, and the front property line is very often not the curb: the strip between sidewalk and street is commonly public right of way, which can put the real boundary several feet inside your lawn. Homeowners who measure from the curb routinely draw a fence in the right of way and get sent back.
Corner lots carry a second front yard along the side street, which is why so many corner-lot fences are limited to 4 feet on a side most people think of as a side yard.
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
Materials and the neighbor question
Two things reviewers and neighbors raise that the drawing can settle in advance:
- Material restrictions. Many zoning codes treat materials differently by yard: chain link is a common fence material that is nonetheless restricted or banned in front yards by a substantial number of cities, and some subdivisions add stricter private rules on top. Barbed wire and electrified fencing are separately regulated in residential zones almost everywhere.
- The finished side. A large number of jurisdictions require the finished side to face outward, toward the street or the neighbor. It is rarely shown on the plan, but it is a real inspection item and an expensive one to discover after the posts are set.
Neither is a building code question. Both live in local zoning codes, and both are worth confirming with the counter before you buy material.
What a fence permit costs
Fences are the cheapest of the five common projects to permit. Among the tracked cities that publish a flat fee, the median is about $50, with the full range running from $5 to $175. Many cities charge nothing at all and handle fences as a zoning review rather than a building permit, which is part of why the permit question feels so inconsistent from town to town.
The zero-fee cities are the ones worth being careful about, because a free review is still a review, and the drawing standards do not relax.
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: a fence site plan runs $89 to $259 and is 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.
