Coastal construction permits are the approvals most likely to be discovered late and least likely to be recoverable when they are. They sit outside the building department entirely, they answer to state and federal law rather than to the building code, and on a South Florida waterfront parcel they routinely determine when construction can begin. This is what applies, and when.
Which approvals count as coastal construction permits?
Four families: authorisation to occupy sovereign submerged lands, environmental resource permitting for impacts to wetlands, seagrass, and protected habitat, Coastal Construction Control Line review seaward of the state line, and federal review for structures in navigable waters. Local floodplain review sits alongside them.
State programmes are published by Florida DEP and the South Florida Water Management District.
What triggers submerged lands authorisation?
Any structure on or over the land below the mean high water line, which the state owns. Seawalls, docks, boat lifts, davits, and any waterward extension all qualify. Owners are frequently surprised that coastal construction permits are required for a structure attached to their own property, but the water bottom is not theirs.
Coastal construction permits therefore reach structures owners consider entirely their own, and the mechanics are in the permitting process for new seawalls.
What does environmental resource review examine?
Water quality during and after construction, impacts to seagrass, mangroves, hardbottom, and protected species, turbidity control during the work, stormwater management, and any required mitigation. Where habitat is present, this is the longest of the coastal construction permits and the one least amenable to acceleration.
Of all coastal construction permits this is the slowest; stormwater requirements are published by Florida DEP and the EPA.
When does the Coastal Construction Control Line apply?
Only along the sandy Atlantic shoreline, to construction seaward of the mapped line, and it reaches further than owners expect: the residence, foundations, pools, decks, dune walkovers, armouring, landscaping that disturbs the dune, and exterior lighting. Its position is established by survey, not by assumption.
The programme is at Florida DEP, with detail in the Coastal Construction Control Line explained.
| Approval | Authority | Triggered by |
|---|---|---|
| Submerged lands authorisation | Florida DEP | Any structure below the mean high water line |
| Environmental resource permit | Florida DEP and the water management district | Impacts to habitat, water quality, or stormwater |
| Coastal Construction Control Line | Florida DEP | Construction seaward of the line on the Atlantic shore |
| Federal navigable waters review | US Army Corps of Engineers | Structures in or affecting navigable waters |
What about lighting and wildlife?
On the oceanfront it is a permit condition, not a preference. Exterior lighting visible from the beach must be designed to protect nesting sea turtles, which affects fixture selection, mounting height, shielding, and control. It is one of the coastal construction permits conditions most often missed until final inspection.
Lighting conditions attach to coastal construction permits on the oceanfront, and the requirements are published by FWC.
What does the federal layer cover?
Structures in or affecting navigable waters of the United States, which covers most Intracoastal and canal frontage connected to navigable channels. The Army Corps reviews under its own authorities, sometimes through streamlined pathways for routine replacement, and species and habitat considerations can extend it.
Waterway rules are published by FWC.
How should these be sequenced?
First, and in parallel with each other. Coastal construction permits run on calendars independent of the building department and frequently exceed it, so they are opened while architectural drawings are still developing. Filing them after the building permit is the single most expensive sequencing error available on a waterfront project.
The sequencing rule is in expediting flood zone and coastal permits.
What belongs in the application?
A signed and sealed survey showing property lines and the mean high water line, engineered drawings with sections and details, geotechnical data, a construction plan showing access, staging, and turbidity controls, environmental resource information where habitat is present, and adjacent-property tie-in details. Complete packages draw comments; incomplete ones draw delay.
Coastal construction permits reward a complete first submittal, and the standard is described in seawall construction and permitting.
How does Kass Construction & Development manage them?
As the first workstream on any waterfront project: Kass Construction & Development, a state-licensed (CGC1529472) boutique luxury builder headquartered in East Fort Lauderdale and led by Mitch Kass, a licensed general contractor and attorney, with 100+ luxury residences over 25+ years across Broward, Palm Beach, and Miami-Dade, opens coastal construction permits before the residence design is finished.
A custom build often runs 14 to 24+ months. Contact Kass Construction & Development or call 954-607-4335.
Frequently Asked Questions
What are coastal construction permits?
Submerged lands authorisation, environmental resource permitting, Coastal Construction Control Line review on the oceanfront, and federal review for navigable waters, alongside local floodplain review.
Why does the state control my waterfront?
Because the land below the mean high water line is sovereign submerged land owned by the state. Any structure occupying it needs authorisation regardless of who owns the upland.
Which review takes longest?
Environmental resource review where seagrass, mangroves, or protected species are present. It is the least amenable to acceleration and should be opened first.
Does the coastal line apply to canal homes?
No. It applies only along the sandy Atlantic shoreline. Canal and Intracoastal properties still need submerged lands and environmental approvals.
Why is exterior lighting a permit issue?
On the oceanfront, artificial light visible from the beach disorients nesting sea turtles, so fixtures, mounting, shielding, and controls are all conditioned.
When should I file these?
First, and in parallel with each other, while architectural drawings are still developing. Filing after the building permit guarantees the project waits.
What makes an application complete?
A sealed survey with the mean high water line, engineered drawings, geotechnical data, a construction and turbidity control plan, environmental information, and tie-in details.
