Do you actually own the sand outside your Longboat Key home, or just the view? If you are buying or selling on the Manatee County side of the island, understanding littoral rights can shape value, access, and what you can build. You want clarity before you invest, and you deserve simple, local guidance you can trust. In this guide, you will learn the Florida rules that matter, how Longboat Key’s shoreline history plays in, and the due diligence steps that keep your deal smooth. Let’s dive in.
Littoral rights in plain English
Littoral rights are the rights you have when your land touches the Gulf or another tidal body of water. They typically include access to the water, reasonable use of the shoreline, and benefits or losses from gradual natural changes. In Florida, these rights are shaped by where the boundary sits at the water’s edge and who owns the sand and seabed beyond it.
The mean high-water line explained
In Florida, private ownership commonly extends to the mean high-water line, which is the ordinary high tide mark. Land seaward of that line is usually sovereign submerged land held in trust by the state for public uses. That means you do not automatically own the dry beach or seabed beyond the mean high-water line. Your survey and title work should show where this line sits for your property at the time of closing.
Accretion, erosion, and avulsion
Beaches move, and your rights can shift with them.
- Accretion is the gradual addition of sand. The upland owner generally gains title to the newly formed land.
- Erosion is the gradual loss of land. The boundary generally moves landward as the beach recedes.
- Avulsion is a sudden change, such as during a storm. Sudden changes generally do not change legal boundaries, even if the physical shoreline moves overnight.
Understanding which process occurred can matter during a sale, especially if a storm or a major project changed the beach profile.
Who owns the beach and water in front
Florida holds submerged lands seaward of the mean high-water line in trust for the public. The public trust includes uses like navigation, fishing, and recreation. You may be able to limit access on private upland portions of the beach up to the mean high-water line, but you cannot exclude the public from state-owned areas seaward of that line. Local access rules and easements also shape how people reach and use the shoreline.
Docks, seawalls, and permits
Waterfront structures in Florida are highly regulated. If you plan to build or maintain a dock, boat lift, seawall, or other shoreline protection, you will likely need approvals from multiple agencies.
- Florida Department of Environmental Protection regulates coastal construction and use of sovereign submerged lands.
- The Board of Trustees of the Internal Improvement Trust Fund manages leases for private uses that occupy state-owned submerged lands.
- The U.S. Army Corps of Engineers may require permits for work affecting navigable waters.
- The Town of Longboat Key and local building departments handle local permits and code requirements.
Before you buy or sell, verify existing permits, any submerged lands leases, and whether structures meet current standards.
Beach renourishment on Longboat Key
Longboat Key has a history of beach nourishment and shoreline stabilization projects. When governments place sand to rebuild a beach, it can change the usable beach profile and raise questions about ownership and access. These projects can also affect where the mean high-water line is set for legal purposes. There is significant case law around these issues, including a leading decision involving Florida beach renourishment. If a project may affect your parcel, factor it into your timeline, valuation, and due diligence.
Manatee side of Longboat Key: what to know
Longboat Key spans Manatee and Sarasota counties. If you are focused on the Manatee County portion, know that policy and beach conditions often cross the county line. The Town of Longboat Key coordinates permits, dune management, and local beach maintenance, and state and federal partners may be involved. Bayfront or canal-front homes on the Manatee side may follow different permitting paths than Gulf-front parcels, especially for docks and seawalls. Always verify which jurisdiction applies to your specific address.
How littoral rights affect your sale or purchase
Littoral rights can influence value, financing, and insurance. Clear private access, compliant docks, and properly maintained seawalls can add appeal and price support. Uncertainty about the mean high-water line, public access, or pending permits can slow a deal, impact insurability, or reduce buyer confidence. Clean documentation and clear explanations will help you avoid surprises at the eleventh hour.
A practical due diligence checklist
Use this checklist to stay ahead of issues on the Manatee County portion of Longboat Key.
Boundary and title
- Order a current boundary survey that shows the mean high-water line and all waterfront structures.
- Confirm legal descriptions, recorded easements, and any submerged land grants or leases.
- Ask your title company about exceptions and any endorsements related to littoral rights.
Permits and authorizations
- Collect permits for docks, lifts, seawalls, revetments, and beach access improvements.
- Verify any state submerged lands lease for a dock or pier and whether it is transferable.
- Confirm structures meet current codes and that there are no open violations.
Association and project records
- For condos or HOAs, confirm who holds title to the beachfront and who maintains it.
- Review meeting minutes and budgets for past or planned assessments tied to nourishment or seawall work.
- Request records of storm damage, erosion, or repairs.
Insurance and hazards
- Confirm FEMA flood zone designations and elevation requirements.
- Get quotes for flood and wind coverage and understand lender requirements.
Agency touchpoints
- Town of Longboat Key Building, Planning and Zoning, and Public Works for local permits and ordinances.
- Manatee County Property Appraiser and Clerk for recorded instruments.
- Florida DEP for coastal permitting and beach management history.
- Board of Trustees for submerged land lease status.
- U.S. Army Corps of Engineers for navigable waters permits.
Common scenarios on Longboat Key
Here are issues we often see and how to think about them.
- A dock extends beyond your lot line. Confirm the alignment with a survey and check for a submerged lands lease or easement. Unauthorized encroachments can delay closing.
- The beach in front of a condo looks wider than last year. It may be due to nourishment or natural accretion. Verify how that affects the mean high-water line and any association responsibilities.
- A seawall shows wear. Get a marine contractor to assess condition and remaining life. Use findings to negotiate repairs or credits.
- You want private beach access. Confirm whether your parcel includes upland beach to the mean high-water line and whether any public access easements exist.

FAQs
What are littoral rights for Longboat Key owners?
- Littoral rights are the rights tied to land that borders the Gulf or other tidal waters, including water access and reasonable shoreline use, shaped by the mean high-water line.
Do I own the beach in front of my home?
- Private ownership commonly extends only to the mean high-water line; land seaward is typically state-owned for public use and requires survey and title review.
Can I build a dock or seawall on Longboat Key?
- Possibly, but you usually need local permits and state approvals, and docks over sovereign submerged lands often require a submerged lands lease.
How do storms or sand shifts affect my boundary?
- Gradual accretion or erosion generally moves the boundary, while sudden avulsive events typically do not change the legal boundary location.
Who pays for beach renourishment projects?
- Funding can come from state and local governments, special assessments, or owners, and renourishment does not automatically give private title to newly placed sand.
How do littoral rights impact closing and financing?
- Clear rights and compliant structures can support value, while unclear boundaries, access questions, or permit issues can slow a closing or affect insurability.
