Thinking about buying or selling a waterfront home in West Palm Beach? The seawall, dock, and surveys can make or break your deal. You want a smooth closing with no surprises, fair insurance costs, and a clear path to future upgrades. In this guide, you will learn how permits work, what documents to collect, how timelines and costs shake out, and how to avoid common pitfalls. Let’s dive in.
Why waterfront prep matters
Waterfront features affect safety, value, and insurability. A strong seawall protects your land from tides and boat wake, while a well‑permitted dock preserves your access and future options. Surveys and flood documents influence lender decisions and insurance premiums. Getting these pieces right early keeps your transaction on track.
Who regulates projects
Several agencies review shoreline work in West Palm Beach. Know the stack before you plan:
- City of West Palm Beach: local building permits, plan review, and inspections.
- Palm Beach County: environmental and shoreline review coordination.
- Florida Department of Environmental Protection: permits and exemptions for seawalls and docks, plus use of state‑owned submerged lands.
- U.S. Army Corps of Engineers: federal review for in‑water work in navigable waters and protected habitats.
- South Florida Water Management District: involvement where canals or wetlands are affected.
- Florida Fish and Wildlife Conservation Commission: species and habitat conditions, including manatee protections.
- FEMA and the National Flood Insurance Program: flood maps and Elevation Certificates that influence insurance and lender requirements.
- Florida Board of Professional Surveyors and Mappers: standards for boundary and elevation surveys.
Expect multi‑agency coordination. Check both DEP and USACE jurisdiction early.
Seawalls: permits and care
When permits are needed
Most new or replacement seawalls require state review. DEP regulates shoreline stabilization and use of sovereignty submerged lands. Narrow exemptions can apply to in‑kind repairs in the same footprint or to certain man‑made canals, but they are fact specific. Projects that extend waterward or affect seagrass often need additional state and federal authorizations.
Design and environmental limits
Florida favors non‑vertical options like rip‑rap or living shorelines where suitable, especially in estuaries and lagoons. If you propose a vertical wall, you may need to show why alternatives are not feasible. Neighboring seawalls, tie‑ins, and habitat constraints can shape the final design.
Inspections, timeline, and costs
Saltwater, tides, and wake wear on seawalls, so periodic inspections are smart. Typical timelines reported locally: about 4 to 8 weeks for permitting and 3 to 6 weeks for construction, depending on scope. Costs vary widely by material, length, access, depth, and mitigation. Local examples range from the low tens of thousands for small repairs to much higher for full replacements. Get site‑specific quotes and engineering.
Seawall tips for buyers and sellers
- Request permit history for any prior seawall work.
- Verify whether the wall sits on your upland or occupies state‑owned submerged land that needed consent or a lease.
- Confirm whether prior work stayed in the same footprint or encroached waterward, which changes permitting.
Docks: rules and tips
Size and exemption basics
Small private docks can qualify for state exemptions when they meet strict size and use limits. Typical thresholds include up to 1,000 square feet in many waters and up to 500 square feet in Outstanding Florida Waters, along with non‑commercial use and no dredging beyond piles. Local registration or building permits may still apply.
Consent to use state lands
If your dock occupies state‑owned submerged land, DEP and the Board of Trustees often limit walkway width, terminal platform area, and overall length. Additional elevation and spacing can be required to protect seagrass.
Federal and species protections
USACE review is common in navigable waters or where seagrass and other resources are present. Expect manatee protection conditions for in‑water work and design tweaks to reduce shading of seagrass.
Dock timeline and costs
Permit timing ranges from several weeks to a few months depending on environmental review and federal involvement. Costs range from the low tens of thousands for simple residential docks to higher budgets for long piers, lifts, or complex features. Local bids are essential.
Dock checks for buyers and sellers
- Confirm permits and any submerged‑land lease or consent.
- Match built dimensions to what was approved.
- Verify the number of slips, use limits, and whether lifts or covers were authorized.
Surveys you will need
Boundary survey
A Florida‑licensed Professional Surveyor and Mapper prepares the boundary survey that sets corners, shoreline lines, and improvements. Agencies and lenders rely on it to confirm property limits and riparian access.
Hydrographic survey
If dredging is proposed or depth affects dock design, a hydrographic or bathymetric survey may be required. Reviews often call for pre‑ and post‑dredge depth data.
Elevation Certificate
The FEMA Elevation Certificate documents ground and structure elevations. Lenders and insurers use it to rate flood risk and to support map changes where eligible.
Who can sign
Florida’s standards require surveys and Elevation Certificates to be signed and sealed by a Florida‑licensed Professional Surveyor and Mapper. These sealed documents are standard in permit and loan files.
Flood zones and insurance
Check the FEMA Flood Insurance Rate Map to see if improvements sit in a Special Flood Hazard Area. Many lenders require flood insurance in these zones. A current Elevation Certificate can reduce premiums when elevations are favorable and is required for certain FEMA map amendments.
Timeline and costs to expect
- Typical sequence: site review and surveys in 1 to 3 weeks, permitting in 4 to 12 or more weeks depending on complexity, and construction from 1 to 8 or more weeks based on scope.
- Budget for more than construction. Include professional fees for surveyors and engineers, permit application fees, environmental mitigation, and compliance items like as‑builts or monitoring. Total costs vary from modest for minor repairs to substantial for full seawalls, long docks, or projects with mitigation.
Buyer checklist
- Get the boundary or as‑built survey, Elevation Certificate, and full permit history.
- Verify what is built against approved permits.
- Ask for any Board of Trustees lease or consent for submerged lands.
- Order a current boundary survey if documents are outdated.
- If you plan upgrades, have a local marine contractor scope feasibility and likely agency triggers.
- Confirm lender flood requirements and whether a map amendment might apply.
Seller checklist
- Gather city, county, DEP, and USACE permits for seawalls and docks.
- Provide the latest as‑built survey and any recorded easements.
- Share the Elevation Certificate and any flood‑insurance claim history.
- Include recent inspection reports, invoices, and warranties for seawall or dock work.
- Add copies of any submerged‑land lease or consent.
Local pros to hire
- Florida‑licensed Professional Surveyor and Mapper for boundary, elevation, and hydrographic work.
- Marine or coastal engineer for seawall design and tiebacks.
- Licensed marine contractor for plans, permits, and construction.
- Environmental consultant for seagrass and manatee assessments when needed.
- Insurance agent familiar with coastal policies and Elevation Certificates.

FAQs
Do I always need a permit to replace a seawall in West Palm Beach?
- Not always; certain in‑kind repairs in the same footprint or projects in some man‑made canals can be exempt under state rules, but many replacements still need DEP review and sometimes USACE authorization.
Who owns the water under my dock in West Palm Beach?
- The State generally holds sovereignty submerged lands in trust; riparian owners may build private docks subject to regulations, and occupying state land often requires consent or a lease.
How do surveys impact financing for a waterfront home?
- Lenders rely on boundary surveys to confirm property limits and on FEMA Elevation Certificates to set flood insurance needs and rates, which can affect approvals and premiums.
How long do dock or seawall permits take locally?
- Simple projects can be permitted in a few weeks to a few months, while complex cases with federal or submerged‑land reviews can take longer.
Can I use a living shoreline instead of a seawall in West Palm Beach?
- Florida encourages non‑vertical shore protection where suitable, and you may need to show why alternatives are not feasible if proposing a vertical wall.
What documents should a seller provide for a waterfront listing?
- Provide permits, the as‑built survey, Elevation Certificate, inspection reports, maintenance records, and any submerged‑land lease or consent.
