In Florida, the beach has two owners. The wet sand below the Mean High Water Line is sovereign land held by the state for everyone, and the dry sand above that line is almost always private property belonging to the adjacent landowner. So the honest answer to who owns the beach in Florida is: both the public and private owners do, split by an invisible line that runs the length of the coast.
The Invisible Line That Divides Ownership
The boundary is called the Mean High Water Line, or MHWL. It is calculated by averaging high tides over a roughly 19-year tidal cycle, and it shifts as the shoreline changes.1National Sea Grant Law Center. Florida’s Beach Renourishment Act Upheld Nothing marks it on the sand. As a rough visual, it tracks where wet sand meets dry sand on a typical day, though the legal measurement is far more precise.
Everything seaward of the MHWL, toward the water, belongs to the State of Florida. Everything landward of it, toward the dunes and buildings, belongs to the upland property owner. You can be standing on public land one step away from private property without any visible change under your feet.
What the Public Can Do on the Wet Sand
Public rights on the state-owned portion are written into the Florida Constitution. Article X, Section 11 declares that lands under navigable waters, including beaches below the mean high water line, are held by the state “in trust for all the people.”2FindLaw. Florida Constitution Art. X, Section 11 – Sovereignty Lands This is the Public Trust Doctrine.
On the wet sand, you can walk, swim, fish, and otherwise recreate. No private party can fence off that strip or chase you off it. The doctrine creates a continuous public corridor along the entire Florida coast. But it stops at the MHWL. On its own, it gives no one the right to put a chair or spread a towel on the dry sand of a privately owned beach.
Why the Dry Sand Is Usually Private
Dry sand above the MHWL is part of the beachfront owner’s parcel. Unless there is a public access easement, a public park, or an established customary-use right, the owner can prevent members of the public from sitting, standing, or crossing there. That is true even if the sand looks indistinguishable from the public beach next to it.
There are only a few ways the public can lawfully use that dry sand: with the owner’s permission, through a government-held easement or dedication, or where a court or local ordinance has recognized that the public has long used it in a way that creates a customary-use right.
Customary Use, and What Changed in 2025
Customary use is a Florida doctrine that can grant the public the right to recreate on privately owned dry sand when the public has used that specific stretch of beach in a way that is ancient, reasonable, uninterrupted, and undisputed.3Florida Senate. Bill Analysis HB 6043 – Recreational Customary Use of Beaches It is a high bar, and it applies beach by beach.
In 2018, the Legislature passed Section 163.035, which required any local government seeking to recognize customary use to first file a lawsuit, identify the specific parcels and uses, and win a judicial declaration from a circuit court. Property owners could intervene, and the government carried the burden of proof.3Florida Senate. Bill Analysis HB 6043 – Recreational Customary Use of Beaches That law effectively blocked cities and counties from simply passing an ordinance.
In 2025, the Legislature reversed course. CS/SB 1622, enacted as Chapter 2025-178, repealed Section 163.035 entirely.4Florida Senate. House Bill 6043 (2025) Local governments can now adopt customary-use ordinances without first getting a court order. The four underlying elements still have to be met, and property owners can still challenge an ordinance in court. What changed is the procedural gate, not the standard. For a visitor, this means the answer to whether you can use a particular dry sand area may now depend on a local ordinance where before it depended on a court ruling.
Walton County, along the Panhandle’s Emerald Coast, pursued judicial declarations under the earlier framework and in 2024 obtained summary judgment recognizing customary use on eight named beach areas, including Grayton, Blue Mountain, Santa Rosa, and Seacrest.5Clark Partington.

How Beach Nourishment Shifts the Line
Florida pumps sand onto eroded beaches through nourishment projects, and when it does, the natural MHWL stops making sense as a property boundary. In those project areas, the state sets an Erosion Control Line, or ECL, that permanently replaces the MHWL as the legal boundary.6Official Internet Site of the Florida Legislature. Florida Statutes 161.141 – Property Rights of State and Private Upland Owners in Beach Restoration Project Areas
Once an ECL is recorded, everything seaward of it belongs to the state, including the newly pumped sand and any future natural additions.7labins.org. Florida Statutes Chapter 161 Beach and Shore Preservation – Section 161.191 The private boundary is frozen at the ECL and no longer moves with accretion or erosion. For someone using the beach, the practical consequence is simple: in a nourishment zone, that wide new strip of sand is public.
How to Actually Reach the Water
Knowing the wet sand is public does not help if you cannot get there. Where the dry sand is private and no customary-use right has been established, the public has no legal right to cross it. You reach the water through designated public access points, public parks, or public rights of way that run to the beach.
Some communities maintain many access points. Walton County, for example, lists more than 50 public access locations, including regional parks with parking and restrooms. In tourist areas these are usually well-signed. In quieter residential stretches, access points can be hard to find and parking near them limited. Looking up the local county’s map of public beach access before you go is worth the few minutes.
What Beachfront Owners Can Enforce
A beachfront owner controls the dry sand up to the MHWL (or the ECL, in a nourishment area). Absent a customary-use right at that location, the owner can tell people to leave, call law enforcement if they refuse, and keep the dry sand clear of chairs, umbrellas, and sunbathers.
Walking onto private dry sand without permission is trespassing under Florida Statute 810.09, a first-degree misdemeanor.8Official Internet Site of the Florida Legislature. Florida Statutes 810.09 – Trespass on Property Other Than Structure or Conveyance In Florida, a first-degree misdemeanor can bring up to a year in jail and a fine of up to $1,000. In practice, most beach encounters start with a verbal warning, and officers often issue a warning or notice to appear rather than arrest on the spot. Repeat or confrontational conduct raises the stakes.
Because the MHWL is invisible, honest mistakes are common. Staying on sand that has been recently washed by the tide is the safest way to avoid a dispute if you are not sure whether a particular stretch is public.
Local Rules Still Apply on Public Sand
Public ownership is not a license to do anything. Local ordinances govern a lot of what happens on the beach and vary by county and municipality. Common restrictions include bans on glass containers and alcohol, leash rules or outright bans on dogs, noise limits, bonfire prohibitions, and overnight hours. What is fine on one beach can draw a citation a few miles down the coast, so a quick check with the local county government or beach patrol before you visit is the simplest way to avoid a surprise.
