California state rules for docks and piers

A private dock or pier often needs several approvals beyond a city building permit.

State Lands Commission lease: the Commission controls state-owned tidelands and submerged lands and the beds of navigable rivers, lakes and bays (Pub. Res. Code §6301). A private dock or pier on those lands generally needs a lease. The Commission must charge rent for private recreational piers on state lands, based on local fair rental values (§6503.5). In some harbors the Legislature has granted tidelands to a city, county or port district, which manages them instead.
Coastal development permit: in the coastal zone a dock needs a CDP (§§30106, 30600). On tidelands, submerged lands or public trust lands, the Coastal Commission issues it, even where the city has a certified Local Coastal Program (§30519(b)).
San Francisco Bay (BCDC): around the Bay you need a permit from the San Francisco Bay Conservation and Development Commission to place fill. Under the McAteer-Petris Act, "fill" includes pilings, structures on pilings, and floating docks moored for long periods (Gov. Code §66632). BCDC's jurisdiction covers the Bay and a 100-foot shoreline band (§66610). The Coastal Act's coastal zone does not include BCDC's area.
Streams and lakes: work that changes the bed, bank or channel of a river, stream or lake requires notifying the Department of Fish and Wildlife (Fish & Game Code §1602).
Federal: structures in navigable waters generally need a U.S. Army Corps of Engineers permit.
Local: many harbors and marinas also require a city or harbor-district permit.
