Boat lift installation in Coral Gables

Which lift suits you

The right lift depends on how you moor.

• Four-post lift: on its own pilings in a slip beside the dock
• Elevator lift: mounted on the seawall face, good where pilings are hard to place
• Floating lift: for jet skis and small boats, no pilings

DERM approval comes before the City

Coral Gables will not take dock, mooring or wharf plans without Miami-Dade DERM's preliminary approval, and revised plans need DERM's stamp again. The permit set also needs a notarised Public Works application, dimensions across the waterway, existing mangroves and the installation method, so a lift or dock design gets settled with the county first.

New lifts need drawings, and often new piles, so the permit comes first.[1]

Cocoplum's own dock plan

Properties in Cocoplum Section II must include a copy of the Cocoplum dock plan with their permit, and every Gables dock submittal shows the dimensions across the waterway. On the winding Gables canals that cross-section drawing is what proves a dock or lift leaves room for boats to pass.

We choose the lift type and position to that rule before anything is ordered.[1]

Mangroves on the plans

Coral Gables dock and wall plans must show existing mangroves, and any trimming falls under Miami-Dade's Class I permit for coastal construction and mangrove trimming. DERM's mangrove permits run 3 years, against 2 years for a short-form structure permit, so a job that touches mangroves is scheduled differently.[1][2]

What makes Coral Gables different

Dock, mooring and wharf plans must show dimensions across the waterway, existing mangroves and the installation method, and carry DERM's preliminary approval; revised plans need a DERM stamp again. Properties in Cocoplum Section II must include a copy of the Cocoplum dock plan. The City also asks for a notarised Public Works permit application, colour photos of existing conditions and a survey.[1]

Fee incentives

Under Resolution 2025-342, living seawalls with pH-neutral cement or modular retrofit panels qualify for a 20% reduction in city permit fees, and a separate fee waiver applies to existing homes making seawall improvements to address sea level rise.[4]

Permits for a new lift

Miami-Dade issues a short-form DERM permit for a lift on a new or existing dock, seawall or bulkhead, as long as a single-family lift does not protrude more than 25% of the waterway width. Florida exempts floating boat lifts and floating platforms up to 500 sq ft combined (200 sq ft in Outstanding Florida Waters). In aquatic preserves, a roof may not overhang more than 1 ft beyond the lift and boat.[2][8][9]

Relocating a lift

Moving a lift to a new slip or a new home is a new installation in the eyes of the permit office, so we plan pilings and permits for the new spot. Removing the old lift and old piles is DERM-exempt in Miami-Dade.[2]
