Full Breakdown
217(B) sits inside the Zoning Code's Accessory Uses and Structures article and sets graduated limits tied to how wide the canal or waterway is. On a canal narrower than 60 feet, a private dock can't protrude more than 5 feet into the water. Where the canal is 60 feet or wider, a private hoist facility can extend an additional 10 feet past the dock. On a canal 100 feet or wider, a dock, with or without a hoist, can extend as far as needed to reach a water depth of minus 4 feet at mean high water, but never more than 100 feet from the mean high water line, and never more than 40 feet or 20 percent of the canal width, whichever is more restrictive; canal width is measured shore to shore at mean high water.
S. Army Corps of Engineers. A boathouse placed in a required rear yard is capped at 600 square feet, and no one may live aboard a boat or use a boathouse as a residence. 071(C)(2).
Violations & Fines
Building or extending a dock, hoist, or boathouse beyond these limits, or starting construction before the required state or federal agency signs off, is a Zoning Code violation enforced through the City's building permit and code enforcement process in Chapter 37, with removal or modification ordered until the structure conforms. Using a boat or boathouse as a residence is independently prohibited under section 158.217(B), regardless of size or setback compliance.
