Florida seawall permits: who reviews the work

Seawall permitting in Florida is not one process. Depending on the scope and the waterway, up to five different bodies can have an interest in the same wall — and the one that matters most to a homeowner is usually the local one.

The common assumption is that a seawall repair is a construction question with a permit attached. For a significant number of Florida properties it is the other way round: the permitting position determines what the project has to be. A required minimum elevation does not care what you intended to spend, and it can convert a like-for-like rebuild into a larger job.

The second assumption worth dropping is that one answer covers Florida. It does not. The requirements below are what we could source for specific jurisdictions. Where we have not sourced a jurisdiction, this page does not guess at it.

Who can be involved

The municipal building division

Almost always, for a wall on private residential shoreline

This is the review most owners actually experience. Hollywood, for example, adopted its own seawall ordinance rather than relying on the county standard alone, and runs seawall submittals through its own Building Division intake.

The county

Where the county sets a standard the city has to meet or exceed

Broward County sets a countywide minimum tidal flood barrier elevation of 5.0 feet NAVD88 with a transition provision running to 2050. Cities may then go further: Miami Beach requires 5.7 feet NAVD, and Fort Lauderdale raised its minimum to 5 feet NAVD from 3.9.

A city utility or stormwater division

Where the shoreline is part of a managed canal system

Cape Coral has over 400 miles of canal and publishes its own seawall design standards, separating freshwater canal shorelines from tidal ones with rules that are specific and measurable.

The state

Depending on the work and the waterway

Florida statute exempts seawall restoration from certain state permitting, but the exemption is measured in inches — and neither exemption supersedes permitting requirements under Chapter 161.

The US Army Corps of Engineers

Depending on the waterway

Work in or affecting navigable waters can pull in a federal review. Whether it applies is a function of the waterway and the scope, not of how large the project feels.

Which of these apply to your property is a function of where it is and what the work involves. We have not verified requirements for every Florida municipality and do not publish a requirement we could not source.

Why the elevation number is the one to find first

Of everything in a seawall permit, the required minimum elevation is the item most likely to change the size of the project. A wall that is structurally sound but below a required elevation may still need to be raised when work crosses a substantial-repair threshold, and raising a wall pulls in cap, tieback and sometimes upland work.

That is precisely the point at which a repair conversation becomes a replacement conversation — the fork is set out in full on the repair-or-replace page. It is also the reason it is worth establishing the permitting position before accepting a quote rather than after: a quote written against the wrong scope is not a cheaper project, just a shorter document.

Published permit costs

GENERAL RANGE
  • $500–$2,000 — Published permit range (general)
  • $1,500–$6,000 — Published permit range (South Florida)

These are published ranges, not quotes, and they cover the permit rather than the work. Engineering, inspection and the construction itself are separate lines — the cost page sets out how far apart the published construction figures are and why.

What to establish before you sign anything

  • Which body reviews shoreline work at your address, and whether the city has its own ordinance layered on the county standard.
  • The minimum elevation that applies to you, and whether your existing wall meets it.
  • Whether your intended scope crosses a substantial-repair threshold, because that is what can trigger the elevation requirement.
  • Whether the design must be prepared by a registered engineering professional, and whether what you have been handed is an engineered design or a contractor’s scope.
  • Who is pulling the permit. A contractor who wants you to pull it as an owner-builder is telling you something — the contractor page covers why that matters.

Local requirements for the areas where we found enough sourced evidence to publish are on the metro pages. Those pages record what the jurisdiction actually published, with the source attached, rather than a summary of what is typical.

Evidence behind this page

GENERAL RANGEGEN-AGENCIES

Seawall permitting can involve several agencies at once, depending on scope and waterway.

  • Depending on the project, review may involve the city or county building department, the Florida Department of Environmental Protection, the regional water management district, and the U.S. Army Corps of Engineers.

Read carefully: Which agencies apply is determined by your specific waterway and scope of work, not by your city alone.

VERIFIEDFS-01

Florida statute exempts seawall restoration from certain state permitting, but the exemption is measured in inches.

  • Section 403.813(1)(e) exempts "the restoration of seawalls at their previous locations or upland of, or within 18 inches waterward of, their previous locations."
  • Section 403.813(1)(o) exempts the construction of private seawalls in wetlands or other surface waters when the construction is between and adjoins at both ends existing seawalls, follows a continuous and uniform seawall construction line with the existing seawalls, is not more than 150 feet in length, and does not violate existing water quality standards, impede navigation, or affect flood control.
  • Neither exemption supersedes permitting requirements under Chapter 161.

Read carefully: An exemption from one agency is not an exemption from all of them. A project can be exempt under 403.813 and still require city, county, water management district or Army Corps authorisation.

Broward County sets a countywide minimum tidal flood barrier elevation of 5.0 feet NAVD88, with a transition provision that runs to 2050.

  • Tidal flood barriers shall have a minimum elevation of five (5) feet NAVD88.
  • Applications for new or substantially repaired or substantially rehabilitated tidal flood barriers submitted prior to January 1, 2035 may be permitted a minimum elevation of four (4) feet NAVD88, if designed and constructed to accommodate a minimum elevation of five (5) feet NAVD88 by January 1, 2050.
  • Adopted by the Broward County Board of County Commissioners on March 31, 2020, as Article XXV of Chapter 39 of the Broward County Code of Ordinances.
  • The standard is written to address flood patterns and sea level rise projections through 2070.
  • The standard does not apply to oceanfront beaches or shorelines seaward of the Coastal Construction Control Line.

Read carefully: The 4-foot figure is a conditional transition allowance, not an alternative standard. It is only available where the barrier is designed and built to be raised to 5 feet by 2050.

Fort Lauderdale raised its minimum seawall and tidal barrier height to 5 feet NAVD, up from 3.9 feet NAVD.

  • The minimum height of seawalls and tidal barriers was raised to 5 feet NAVD, up from 3.9 feet NAVD, to comply with Broward County standards.
  • Three conditions require a property owner to raise a seawall: building a new seawall; a seawall in significant disrepair, defined as damage to more than 50% of the structure; or the owner being cited for tidal flow breaching the seawall and impacting a neighbouring property or right of way.
  • The City mailed more than 8,000 postcards to waterfront property owners about the change.

Miami Beach requires a higher seawall elevation than the Broward County standard — 5.7 feet NAVD.

  • All new seawalls must be constructed to an elevation of 5.7 feet NAVD, or 4 feet NAVD if designed to support a future elevation of 5.7 feet NAVD.
  • In January 2021 the City strengthened a 2016 policy into an ordinance requiring new seawalls at 5.7 feet NAVD and requiring failing seawalls to be rebuilt to that minimum.
  • The City updated the Seawall Ordinance on July 23, 2025, changing definitions and construction standards for new and existing seawalls and other tidal flood barriers.

Read carefully: Crossing a municipal line in South Florida can change the required elevation. Miami Beach at 5.7 feet NAVD and Broward at 5.0 feet NAVD88 are different numbers on different data.

Hollywood adopted its own seawall ordinance rather than relying on the county standard alone.

  • The City updated its seawall ordinance (O-2022-01) on February 2, 2022, establishing tidal flood protection regulations and creating section 150.30 covering construction and infrastructure standards for seawalls and tidal flooding barriers that account for projected sea level rise.
  • Hollywood is one of 17 Broward municipalities with tidally influenced waterways addressed by the county policy and companion model ordinance.

Questions we can answer from sources

Do I need a permit to repair my seawall in Florida?
Assume yes and confirm locally. Florida statute exempts seawall restoration from certain state permitting, but that exemption is measured in inches and does not remove local review. The municipal building division is the review most residential owners actually encounter, and several Florida cities run seawall submittals through their own dedicated intake.
Does the statutory exemption mean no permit at all?
No. The exemption is narrow, it is dimensional rather than general, and it does not supersede permitting requirements under Chapter 161. A repair that stays inside the exemption for state purposes can still require local review, and the local review is where elevation requirements live.
What elevation will my seawall have to meet?
It depends on the municipality, and the differences are real rather than technical. Broward County sets a countywide minimum of 5.0 feet NAVD88 with a transition provision to 2050; Miami Beach requires 5.7 feet NAVD; Fort Lauderdale raised its minimum to 5 feet NAVD from 3.9. Two waterfront properties twenty minutes apart can face different numbers.
What does seawall permitting cost?
Published permit figures we could find run roughly $500 to $2,000 as a general range, with a separate South Florida range reported at $1,500 to $6,000. Those are published ranges rather than quotes, and permitting is one line in a project, not the project.
Who prepares the design that gets submitted?
Where a jurisdiction requires it, a registered engineering professional. Cape Coral, for instance, has seawalls designed by registered engineering professionals and reviewed, permitted and inspected on completion. A contractor quoting a scope is not the same thing as an engineer specifying one, and it is worth knowing which you have been given.
