Contra Costa County, CA Environmental Rules: Boat Dock Permits (2026)

610, part of the local modifications to the adopted California Electrical Code, requires that boat docks, whether open or roofed, be lit to ensure sufficient protective lighting of at least two foot-candles at all points for pedestrians on the docks, within covered berths, and on all walkways or ramps leading to shore and to the nearest access road within or adjacent to the harbor property. 602 requires the county building official's written authorization before energizing any equipment requiring a permit, so dock lighting installed or altered as part of permitted work is inspected under that authority.

402 lets the building official order repairs to dangerous or unsafe dock wiring or fixtures within ten days of notice, or immediate de-energizing if the hazard is imminent. 612, the county's public nuisance lighting rule, which requires fixtures to be installed, controlled or directed so the light does not glare or blind pedestrians, vehicular traffic, or adjoining property, meaning a marina or private dock cannot meet the two-foot-candle minimum by aiming fixtures into a neighbor's yard or the water traffic lane. 608 additionally bars an occupancy with commercially supplied electricity, such as a marina with dock power, from running a permanent or temporary generator unless the county building official authorizes it for commercial purposes.
