FRANKSVILLE, WI – October 22, 2026 – PRESSADVANTAGE –
Wisconsin’s revised electrical code took effect September 1, 2026, changing the rules that apply to covered new wiring work. The update matters when deck plans include hardwired lighting, although the code change does not alter the structural rules for a deck. Excel Custom Decks lists deck and stair lighting among its existing services in the Franksville area, making the distinction between fixture placement and electrical work relevant to its projects.
The state’s final rule, identified as CR 26-016, was published June 29 before taking effect in September. It updates Wisconsin’s electrical code, SPS 316, from a reference to the 2017 National Electrical Code to the 2023 edition, with state-specific changes. The adopted Wisconsin text, rather than a generic summary of the national edition, is the starting point for assessing a proposed installation.
A deck plan can place lights along steps, railings or seating areas without showing how power will reach them. That gap becomes important when the design calls for a new circuit, changes an existing circuit or includes equipment whose installation needs electrical review. The rule’s discussion of outside branch circuits and feeders is about electrical work, not a blanket requirement that every deck have lights or that every existing fixture be replaced.
The difference is practical for a homeowner planning a new structure. Fixture locations affect the deck layout and where wires may need to pass before surfaces are closed. Electrical design, however, depends on the supply, wiring method, equipment and property conditions. A drawing that shows only a row of lights does not settle those questions, and the deck permit alone should not be treated as permission for separate electrical work.
The rule also addresses state exceptions involving ground-fault and arc-fault protection. Those passages cannot be reduced to a single instruction for every light beside a stair. A professional evaluating a proposed circuit needs the adopted text and the specific installation details, not an assumption that an online description of the 2023 national code applies without modification. The governing inspection authority and any permit or exemption depend on the actual work and location.
Excel Custom Decks’ deck-lighting page describes LED and solar-powered choices, as well as lighting for decks and stairs. A self-contained solar fixture and a hardwired system do not present the same electrical questions. The company’s service description establishes the lighting category, but it does not identify who performs licensed circuit work on a particular job or announce a new installation program under the September rule.
For a project combining a deck and lights, the construction and electrical scopes should be described separately before work begins. A replacement fixture using an existing supply is not the same proposal as a new feed from the house. The plan should identify what remains, what changes and which party is responsible for each portion. That gives the appropriate electrical professional and inspection office something concrete to review rather than asking them to approve a vague promise of “deck lighting.”
A Franksville mailing address does not, by itself, determine the property’s permitting jurisdiction. Municipal boundaries and the precise work matter when identifying the office that reviews an application or schedules an inspection. The September state update does not create a special deck-lighting permit track, replace a deck’s building review or automatically reopen a completed installation. Specific requirements should be checked against the property’s authority and the final electrical scope.
The immediate change for homeowners considering wired deck lighting is the state’s new electrical baseline. Its effect can be assessed only after the proposed equipment and wiring are described. The published rule provides the code source, while Excel Custom Decks’ existing service page describes the lighting work the company markets. Neither source documents a company-specific code response or a completed project under the new rule.
