Summary
St. Petersburg requires a permit before building, expanding or reconstructing a residential or commercial dock under City Code § 16.50.130. Docks must qualify as an accessory use to contiguous upland property, a legally platted noncontiguous water lot, a commercial marina, or a multifamily/planned development, and must meet numeric side-setback, size and depth standards before the Planning and Economic Development Department will approve them.
A permit is required prior to the start of construction. ... Applications for a dock permit shall be processed only if the dock is associated with one of the following: 1. Accessory uses to contiguous upland properties. One dock may be permitted and constructed as an accessory use to an existing lawfully permitted principal use on contiguous upland property. One pair of davits may be constructed on or next to a seawall as an accessory use if there is no dock, if the davits meet the side setbacks for the property and are designed to function independently of the seawall.
