Florida dock permit: DEP exemptions, general permits and the free self-certification

On Florida DEP docks water, the lake operator is the real permit gate. Here is who issues it, the rules, the fees and the official sources — before you build or buy.

How to get the permit

• DEP (or a water management district) regulates docks in, on or over surface waters and wetlands.
• Many single-family docks qualify for DEP's free online self-certification. Others need an exemption verification, a General Permit or an Individual ERP.
• Over state-owned submerged land you also need written authorization — usually a Letter of Consent, which requires proof of upland ownership.
• Apply through the DEP Business Portal. Typical review: 30 days for an exemption or General Permit, 60 days for an Individual permit.
• Federal approval for many docks comes through the Corps' SPGP VI, coordinated through DEP.

Size and placement rules

• Exempt size, per DEP's dock fee sheet: up to 500 sq ft over water in Outstanding Florida Waters; up to 1,000 sq ft elsewhere and in canals. Roofs and canopies count.
• General Permit: up to 2,000 sq ft, no more than 2 vessels. Individual ERP: no fixed limit.
• Single-family docks may reach no more than 500 ft past mean high water or 20% of the waterbody width, whichever is less. 25 ft from riparian lines (10 ft for marginal docks).
• In aquatic preserves: walkways up to 4 ft wide, terminal platform up to 160 sq ft, reaching only to -4 ft MLW.

Fees

• Per DEP's dock fee sheet (May 2020): self-certification free · exemption verification $100 · General Permit $250 · Individual ERP $420 ($100 less through e-application). Confirm the current fee with DEP.

Buying or selling a lake house

• Looking up a permit on a property? DEP's MapDirect shows ERP permits including verified exemptions and self-certifications. The Water Permitting Portal covers 2007 onward but leaves out exempt projects. Nexus/OCULUS holds the documents.

Other layers that can apply

• Town or county — zoning, shoreland and building permits.
• State — see the state page for your lake.
• Federal — Army Corps Section 10 / Section 404 where the work triggers them.
