Summary

Florissant requires an electrical permit from the Public Works Department before any wiring, alarm, data or low-voltage work begins, issued under the adopted 2020 National Electrical Code. Permits are non-transferable, must be kept on-site for inspection, and expire if work is not started within six months or sits abandoned that long. A homeowner permit lets an owner-occupant wire their own detached single-family home under conditions.

Section 89.2 Permits Required (Added). Electrical permits must be obtained from the City of Florissant Public Works Department prior to any construction, alteration, addition, or modification to any system supplying or transferring electrical power, alarms, data transmission, or low voltage electricity. The permit fees for electrical permits shall be in accordance with the permit fee schedule as established by the City of Florissant, Missouri. No permit issued under these provisions of the Code shall be assignable or transferable or be used to aid or abet any unlicensed or unauthorized person, firm or corporation in the performance of electrical work. ... Section 89.3 Violation penalties (Added). Any person, firm, corporation, limited liability company or other business entity who shall violate any provision of this code shall be subject to the penalties of Section 100.080 of the Code of Ordinances of the City of Florissant. Each day that a violation continues after due notice has been served shall be deemed a separate offense.

Full Breakdown

The National Electrical Code, 2020 Edition, was adopted for Florissant by Ordinance No. 2 makes an electrical permit mandatory before any construction, alteration, addition or modification to a system that supplies or transfers electrical power, alarms, data transmission or low-voltage electricity. The permit is issued through the Public Works Department, is not assignable or transferable, and a true copy must stay on the job site, open to inspection, until the work is finished. 2 allows an extension up to thirty days before that expiration date.

3 for a false statement or misrepresentation in the application. 5. 5 limits who can do the work: only a St. Louis County-licensed Master Electrician, Journeyman Electrician, Registered Electrician or apprentice working under a licensed contractor may install, alter or repair electrical facilities, with a separate county license covering low-voltage and data work. 3 carves out a Homeowner Electrical Permit for an owner or immediate family member doing their own work on a detached single-family home they occupy, but it excludes the main service, service entrance conductors, meter box and main panel, and the Building Official may require a competency test before issuing it.

Violations & Fines

Working without a permit, or violating any provision of the Electrical Code, exposes the responsible person, firm or corporation to the penalties set in Section 100.080 of the Code of Ordinances, and Section 89.3 makes each day a violation continues after notice a separate offense. Section 89.4 authorizes a stop-work order for the same violations, and Section 89.5.1 makes it unlawful to engage in the electrical or communication business in Florissant without the required county license.
