Anyone who wants to put up a new fence in Florida runs into paperwork fast. One of the most important pieces is a plat of survey. This drawing shows the real shape and size of a property. Permit reviewers use it to check where a fence can legally go. Property owners in Miami, Florida run into this step often, especially in Miami-Dade County, where fence rules are spelled out in detail. This post breaks down what a plat of survey needs to show. It also covers why an outdated one can slow a permit down.

What a Plat of Survey Must Show for a Fence Permit

A plat of survey gives reviewers a scaled picture of the property. That means the lot’s true size and shape. It’s drawn small enough to fit on paper, but it stays accurate to the inch. It also shows existing structures. That includes the house, any sheds, and the lines that mark where the lot ends.

Streets and other site features show up too. A reviewer looking at a fence application uses this drawing as the base document. They check it against the plan for the new fence. Then they see if everything lines up.

The City of Miami requires a recent, scaled site survey for fence-permit applications. That rule exists for a simple reason. A fence plan means little without an accurate picture of the land under it. Reviewers need a real, current drawing, not a rough sketch from memory.

How the Proposed Fence and Gate Are Marked on the Survey

Once the base survey is ready, the next step matters just as much. Someone has to mark where the new fence and gate will actually go. This isn’t guesswork. The planned fence line needs to be drawn clearly, right on the plat. That way reviewers can see exactly where it sits.

Gate locations matter just as much as the fence line. A reviewer needs to see how close the gate sits to the house. They also check its distance from the lot lines and anything else already on the property. If the drawing is vague or hard to read, questions come up fast.

Miami-Dade County specifically requires the proposed fence or gate location to be marked on the land survey or site plan. That’s not a small detail. Skipping it, or drawing it poorly, is one of the easiest ways to get an application sent back for corrections.

Using the Plat to Document Fence Height, Materials, and Layout

The plat doesn’t work alone. It pairs with separate fence-detail drawings that spell out the specifics of the project. Together, these documents tell reviewers what’s actually being built.

That means listing the proposed height of the fence. It also means naming the material, such as wood, chain-link, or something else. The design type needs to be clear too. So does the total length of the fence, along with where any gates sit along that length.

City of Miami permit guidance requires details such as fence height, material, type, and property location. Getting these details right the first time keeps the whole review moving. Skip a number or leave a description too vague, and the process stalls.

Showing Easements and Restricted Areas Before Permit Review

Easements are a common reason fence plans hit a snag. A plat might show a utility easement crossing part of the lot. It might show a canal easement instead. Either way, that area often comes with extra rules attached.

A fence planned inside one of these zones might still get approved. But it may need extra steps first. Reviewers sometimes ask for additional forms. Sometimes they need a release from the utility company before signing off. In some cases, the fence has to shift to clear the easement entirely.

Miami-Dade County requires an additional permit addendum in certain utility-easement situations. Catching this early saves a lot of back-and-forth later. Nobody wants to redesign a fence layout after the county has already flagged a conflict.

Why an Outdated Plat May Delay a Fence or Gate Permit

A survey drawn five or ten years ago might not match the property anymore. Maybe a pool got added. Maybe a shed went up in the backyard. Maybe a driveway got wider. None of that shows up on an old plat, and reviewers notice.

When a submitted survey doesn’t match what’s actually on the ground, the fence proposal can’t be checked properly. That mismatch is one of the top reasons permit offices send back correction requests. Approving the application outright just isn’t possible.

The City of Miami states that its required survey generally cannot be more than one year old. Miami-Dade County takes a similar stance. It requires the survey to reflect the current property layout. An outdated or hard-to-read plat doesn’t just risk a delay. It can mean starting the whole review process over.

Frequently Asked Questions

Is a plat of survey required for every fence permit in Miami? 

Requirements depend on the permitting authority and the project type. Both the City of Miami and Miami-Dade County list a survey or site plan among the standard documents for fence-permit applications. Property owners should confirm the exact rules with the municipality responsible for their address.

Can the fence contractor draw the proposed fence on the plat? 

The proposed layout may be drawn on the survey or included in a separate site plan. It just needs to meet the reviewing authority’s requirements. The drawing should clearly show the fence and gate locations. It should also stay legible and drawn to scale where required.

How recent must a survey be for a City of Miami fence permit? 

The City of Miami states that the site survey must be prepared by a certified surveyor. It must be drawn to scale and no more than one year old.

Should gates be included on the permit survey? 

Yes. The planned locations of gates should be shown along with the fence layout. Miami-Dade County also asks applicants to include gates when reporting the total linear footage of the proposed installation.

What happens when a proposed fence crosses a utility easement? 

The permit authority may require an additional addendum. It may also ask for utility-related documentation, or changes to the proposed placement. Approval isn’t guaranteed just because the fence location appears on the survey.
