Summary
Cape Coral requires a building permit before any dock, wharf, mooring pile, or boat canopy is built on a waterfront lot, under Land Development Code Section 5.4.1. City rules then cap how far a dock can project into a canal, generally limiting it to six feet unless it stays within 25 percent of the waterway's width or 40 feet, whichever is less, and the waterway must stay at least 50 percent navigable.
In order to allow all waterfront property the same ability to utilize and access adjacent waterways, the development of docks, wharves, mooring piles, and watercraft moorings must be accomplished in a standard and unified manner. Marine improvements and boat canopies may be constructed by the owner of a waterfront lot after complying with the provisions of Chapter 4 of this article and receiving a building permit from the City.

Full Breakdown
Section 5.4.1 of the Land Development Code states that marine improvements and boat canopies may only be constructed by the owner of a waterfront lot 'after complying with the provisions of Chapter 4 of this article and receiving a building permit from the City.' Chapter 4 then lays out the technical rules permit reviewers apply. Section 5.4.2 bars any dock or piling that would reduce the navigable portion of a waterway below 50 percent of its calculated width, and it makes the property owner solely responsible for compliance with the Lee County Manatee Protection Plan. A Florida-registered professional engineer must design and seal the plans for any marine improvement in a non-residential zoning district, for public projects, and for any marine improvement built of concrete.
Section 5.4.3's dimensional standards set the actual footprint limits: a dock that projects no more than six feet from the water frontage line can run the full width of the lot, but anything projecting farther is generally capped at 25 percent of the calculated waterway width or 40 feet, whichever is less, and must stay at least 12 feet from the ends of the water frontage line. Parcels at canal ends, on lakes and basins, or on outside corners get separate formulas, and maximum dock surface area is calculated from the lot's linear waterfrontage. Every marine improvement must also stay clear of any vessel extending past the property's own water frontage, except for joint marine improvement arrangements the Code separately allows.
Violations & Fines
Building a dock, lift, or other marine improvement without the required permit, or beyond the projection and surface-area limits in Section 5.4.3, is a Land Development Code violation the Department of Community Development enforces through Cape Coral's Code Compliance Special Magistrate process. Because Section 5.4.2.F treats the city's waterways as public rights-of-way, the city can order any marine improvement or boat canopy relocated or removed for public health, safety, or welfare at any time, whether or not it was originally permitted.
