What Is a Land Survey? Beginner's Guide for Florida Homeowners

If you own property in Florida — or are about to buy some — you have probably heard the term "land survey." But what exactly is it, and when do you actually need one? This guide explains land surveys in plain language, covering what they measure, when Florida homeowners need them, and what to expect from the process.

What Is a Land Survey?

A land survey is a precise measurement and mapping of a piece of land performed by a licensed professional. The surveyor uses specialized instruments — GPS receivers, total stations, drones, and laser scanners — to determine the exact location of property boundaries, structures, elevations, and other features.

In Florida, land surveys must be performed by a Professional Surveyor and Mapper (PSM) licensed by the Florida Department of Agriculture and Consumer Services under Chapter 472 of Florida Statutes. The PSM signs and seals the survey, making it a legal document.

A land survey answers three fundamental questions about your property:

1. Where are the boundaries? The exact location of your property lines and corners
2. What is on the property? The position of buildings, fences, driveways, utilities, and natural features
3. What affects the property? Easements, setbacks, flood zones, and encroachments

What Does a Land Survey Show?

A completed survey map (also called a plat or survey drawing) typically includes:

• Property boundaries: Lines with precise distances (in feet) and bearings (compass directions)
• Corner monuments: The location of iron rods, pipes, or concrete markers at each property corner
• Improvements: Buildings, fences, driveways, pools, and other structures with their distances from property lines
• Easements: Areas where utilities or neighbors have legal access rights across your property
• Setback lines: The minimum distance structures must be from property lines per local zoning
• Total area: The property size in square feet or acres
• Encroachments: Any structures that cross property lines — yours or your neighbor's
• Flood zone: FEMA flood zone designation (especially important in Florida)
• Legal description: Reference to the recorded plat, lot number, and subdivision

8 Times You Need a Land Survey in Florida

1. Buying a home: A survey protects you from inheriting boundary disputes, encroachments, or easement problems. Most title companies and lenders recommend or require one.
2. Building a fence: Most Florida counties require a boundary survey for fence permits. Building on the wrong side of the line can mean forced removal at your expense. See our fence survey guide.
3. Construction or additions: Building permits require a survey showing your lot, setbacks, and buildable area. See construction survey requirements.
4. Selling your property: A current survey gives the buyer confidence and can prevent delays at closing.
5. Property line dispute: A certified survey is the definitive legal authority on where your property ends and your neighbor's begins. See our dispute resolution guide.
6. Flood insurance: An elevation certificate (a specialized survey product) can reduce your flood insurance premiums.
7. Lot split or subdivision: Dividing a parcel into multiple lots requires a recorded plat prepared by a licensed surveyor.
8. Title insurance: Title companies may require a survey to issue a policy without survey exceptions, especially for commercial properties.

How the Survey Process Works

A typical residential boundary survey follows these steps:

1. Request a quote: Provide your property address, survey type needed, and timeline. Most companies quote within a few hours.
2. Research: The surveyor reviews your deed, recorded plats, prior surveys, and title documents at the county Clerk of Court.
3. Fieldwork: A crew visits your property to locate existing monuments, measure boundaries, and collect data using GPS and total stations. This typically takes 2-4 hours for a residential lot.
4. Calculations: The surveyor compares field measurements to the legal description and resolves any discrepancies.
5. Monument setting: Iron rods with caps are set at each property corner that lacks an existing marker.
6. Survey map: The PSM prepares, signs, and seals a survey map showing all boundaries, dimensions, improvements, and easements.
7. Delivery: You receive a sealed copy (hard copy or digital PDF). The survey becomes part of the permanent record.

Most residential boundary surveys are completed within 3-7 business days. See our guide on how long a land survey takes for details.

How Much Does a Land Survey Cost?
