Seawalls and Dock Permits in Miami: A Buyer’s Guide

If you are buying a Miami waterfront home, the permits behind the seawall and dock matter as much as the

ones behind the house. This is the part of the transaction that quietly derails deals, and 2025 brought

some of the biggest changes in decades. Here is what you need to know before you sign anything.

Who regulates the water’s edge

Work at the shoreline can involve several agencies at once, which is exactly why so many owners get

confused about who to even call. Approval from Miami-Dade County’s Division of Environmental

Resources Management, the Coastal Resources Section, is central to seawall and dock work. Depending

on the project, the Florida Department of Environmental Protection, the South Florida Water Management

District, and the U.S. Army Corps of Engineers may also have jurisdiction, alongside your city building

department. Any new seawall, seawall cap, dock, boat lift, or dredging typically requires a permit, and in

many cases more than one agency has to sign off before work can begin. A good waterfront contractor or

permit expediter will already know which combination applies to a given property, which is worth its weight

in gold if you are the one paying for delays.

The 2025 reforms changed the game

Two developments matter for buyers right now, and both are genuinely significant shifts from how things

worked even a couple of years ago.

First, elevation. Miami Beach’s July 2025 ordinance requires seawalls to reach 5.7 feet NAVD elevation,

with a 730-day compliance window, and where repairs are substantial, the wall must be brought up to that

required height. This is part of a broader regional push to raise seawalls against rising water, and other

municipalities across Miami-Dade are expected to follow a similar path in the coming years, so a compliant

wall today is a genuine selling point, not just a box to tick.

Second, speed. Miami-Dade introduced sweeping permitting reform, including a new centralized Gold Key

permitting portal, with a target that most seawall and bulkhead permits are reviewed and issued within 90

days, a dramatic improvement over prior waits that could stretch up to two years. For buyers planning

renovations or a new dock, that difference alone can change whether a project is realistic within your

ownership timeline.

What this means when you buy

Do not assume the seawall is compliant just because it is standing. Before you close, establish three

things: the current condition of the seawall, whether it meets, or will soon be required to meet, the new

elevation standard, and whether existing dock and lift structures were properly permitted. It is also worth

asking directly whether any permits are still open or unresolved from prior work, since an open permit can

follow the property and become your problem to close out. An unpermitted dock or a seawall facing a

mandatory elevation upgrade is a real, quantifiable cost that belongs in your negotiation, not your first

surprise as an owner.

The takeaway

The 2025 reforms are good news, faster, clearer permitting and a serious commitment to protecting these

properties long term. But they also mean elevation standards are rising, and buyers need to know exactly

where a given seawall stands relative to that standard. This is precisely the kind of detail that separates an

informed purchase from an expensive lesson, and it is worth building into your due diligence checklist

alongside the usual inspection and survey.
