Summary

In the City of Janesville, installing or altering electrical wiring, fire alarm systems or life-safety circuits needs a permit from the Electrical Inspector under Code of General Ordinances § 10-90, pulled by a Wisconsin-licensed Electrical Contractor. Minor repairs defined in § 10-92(b) are exempt, and permits expire 12 months after issuance.

(a)Before any electrical wires or electrical apparatus shall be installed for lighting or power purposes, including fire alarm, area of refuge, and other such emergency and life safety systems, or any electrical construction work done, except minor electrical work, an electrical permit shall be obtained from the Electrical Inspector by a State of Wisconsin licensed Electrical Contractor as defined in SPS 305. ... (e)Electrical permits shall expire 12 months after the date of issuance of the permit. If such permit expires, a new permit shall be issued at the regular fee rate.

Full Breakdown

Before any wiring or apparatus for lighting, power, fire alarm, area-of-refuge or other emergency systems is installed, § 10-90(a) requires an electrical permit obtained by a State of Wisconsin licensed Electrical Contractor, who must be or employ a Licensed Master Electrician or Residential Master Electrician under SPS 305. A permit is also required for outlet installation and low-voltage wiring (50 volts and below) under § 10-90(b), and for demolition or removal of panelboards, transformers and similar equipment under § 10-90(c). Emergency work may start before a permit issues if the Electrical Inspector is notified the same day, or the next business day if the Building Division is closed, per § 10-90(d).

Permits expire 12 months after issuance and require a new permit at the regular fee if they lapse, § 10-90(e). Contractors must annually file license copies, addresses and phone numbers for both the licensed contractor and the master electrician under § 10-91(a), and homeowners may only self-install branch circuit wiring in their own single-family residence, § 10-91(d). Section 10-92(a) adopts the current National Electrical Code and Wis. Admin. Code SPS 316 and 305 by reference. The Electrical Inspector can disconnect service immediately in an emergency or safety-risk situation under § 10-89(g)(2), and after-hours inspections carry a special fee under § 10-89(h).

Variances to the NEC go to the State; variances to the local article go to the City of Janesville Zoning Board of Appeals under § 10-96.

Violations & Fines

Under § 10-97, anyone who violates the Electrical Code or an order issued under it faces a fine of not less than $25.00 nor more than $500.00 plus prosecution costs upon conviction. Nonpayment can mean commitment to the Rock County Jail for not less than five nor more than 60 days. Each day a violation continues is a separate offense, and beyond the fine the City may pursue injunction, mandamus or abatement action, and the City Council may revoke any related license or permit.

Frequently Asked Questions

Do I need a permit to replace a light fixture in Janesville?
No. Section 10-92(b) defines minor electrical work, such as replacing an existing light fixture, receptacle, motor or lighting ballast that is broken or not functioning, as exempt under § 10-90(a)(2). Anything beyond a like-for-like fix, such as new circuits, added receptacles or relocated devices, still needs a permit from the Electrical Inspector.
Who is allowed to pull an electrical permit in Janesville?
Only a State of Wisconsin licensed Electrical Contractor, or the Master or Residential Master Electrician that contractor employs, under § 10-90(a) and § 10-91. Homeowners may self-perform branch circuit wiring in their own single-family residence under § 10-91(d), but not service or feeder work.
How long does a Janesville electrical permit stay valid?
Twelve months from the date of issuance under § 10-90(e). If the permit lapses before the work and required inspections are finished, a brand-new permit must be obtained at the regular fee rate, so contractors should schedule the Electrical Inspector's inspections under § 10-89 well before expiration.
What happens if the Electrical Inspector finds unsafe wiring?
Under § 10-89(g), the owner gets written notice to fix or remove the hazard within a specified time. In an emergency or immediate fire or safety risk, the Inspector can disconnect service on the spot and attach an official tag, and it is unlawful for anyone to remove or deface that tag under § 10-89(g)(3).
