Summary

Anyone building a residential dock or pier in unincorporated Franklin County must follow the site plan and construction standards in Franklin County Code §§ 5-82 and 5-83: canal docks are capped at 25 percent of the canal's width, no vehicles or clearing is allowed within the 50-foot critical habitat zone, and every fixture must be motion-activated or three-way-switched and shielded downward.

These county ordinances apply to unincorporated areas of Franklin County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(a)Comply with the permitting requirements for all other governmental agencies having jurisdiction over the project. (Evidence of an exemption from such compliance must be furnished by the homeowner before approval can be granted.)(b)Be elevated a minimum of five (5) feet above mean high water, except that the terminal platform may be lower at the owner's discretion. ... (d)No dusk to dawn lights. Must be able to switch off or on by motion detector, or be activated by a three-way switch.( ... f)All lights must be downward directed and have adequate shielding to prevent light trespass and minimize light pollution from light scatter.

Full Breakdown

Franklin County Code § 5-82 sets the site-plan rules a residential dock or pier permit must satisfy: a dock built on a canal cannot exceed 25 percent of the canal's width including the mooring area, the underlying lot has to be large enough for a single-family dwelling (or qualify for a board of adjustment variance for hardship), no dry-dock facilities or fuel pumps are allowed beyond boat lifts attached to the dock, and boat ramps are permitted only if the lot has room to park trailers, with no commercial docking or launching.

No vehicle parking or land-clearing is allowed within the critical habitat zone, defined as the first 50 feet landward of mean high water, which must stay in natural vegetation. Section 5-83 layers on construction standards: the applicant must show compliance, or an exemption, from every other agency with jurisdiction over the project, the structure must be elevated at least 5 feet above mean high water, except the terminal platform at the owner's discretion and parallel docks extending no more than 25 feet from the water's edge, and pilings must be set at least 8 feet apart center to center.

Lighting is tightly capped: no dusk-to-dawn lights are allowed, fixtures must switch off by motion detector or three-way switch, only a handful of lights are permitted along most docks, one on the terminal platform, one at the landward end, and one every 100 feet between, every light must be downward-directed and shielded against light trespass, and amber nighttime reflectors are required at the sides and terminal. A surveyor's riparian-rights survey must accompany the application unless the dock sits at least 25 feet from the property line, and existing docks had 180 days from enactment to retrofit their lighting and reflectors.

Violations & Fines

A dock or pier built without meeting §§ 5-82 and 5-83's site-plan and construction standards, including the lighting and setback rules, is a code enforcement matter handled by the Franklin County Planning and Building Department, which can require retrofits, deny a certificate of occupancy for the structure, or refer the noncompliant dock for county code enforcement action.

Frequently Asked Questions

How wide can I build a dock on my Franklin County canal lot?
Section 5-82(a) caps a canal dock, including its boat mooring site, at 25 percent of the canal's width. The county also requires the underlying lot to be large enough to support a single-family dwelling, or you need a hardship variance from the board of adjustment.
Can I leave a light on my dock running all night?
No. Section 5-83(d) prohibits dusk-to-dawn lighting on residential docks; every fixture must be switchable off by motion detector or a three-way switch. Lighting is also capped at one fixture on the terminal platform, one at the landward end and one every 100 feet, all downward-directed and shielded.
Do I need a survey to get a dock permit?
Yes, unless your dock will sit at least 25 feet from your existing property lines. Section 5-83(i) requires a professional surveyor's riparian-rights survey with the permit application in every other case.
