Summary

Cincinnati requires a separate electrical permit before any wiring or electrical equipment is installed, extended, or altered in a building. The electrical inspection agency must approve the work and complete required inspections before current may be supplied.

1101-17.4 Electrical permits: Separate and distinct permits shall be required for electrical work as set out in §§ 1101-17.4.1 and 1101-17.4.2 CBC. Exception: Replacement gas or oil furnaces and boilers, replacement heat pumps, and replacement air conditioning equipment, connected to existing branch circuits in single, two or three family dwellings. 1101-19.6 Electrical Permits: Electrical wiring or equipment shall not be installed within or on any building or structure or premises, nor shall any alteration be made in any such existing installations without first securing approval from the electrical inspection agency. It shall be unlawful to use or permit the use of, or to supply current for an electrical system in a building or structure, unless the required inspections and approvals have been made by the electrical inspection agency.

Full Breakdown

Violations & Fines

Under CBC § 1101-51.1, any owner, agent, or person in control who violates any provision of the code, including performing electrical work without the required permit or supplying current before inspections and approvals are complete, is guilty of a misdemeanor of the first degree. Each day the violation continues after notice constitutes a separate offense, and accessories to the violation (contractors, electricians, employees) face a minor misdemeanor on a first offense and a fourth-degree misdemeanor on repeat offenses under § 1101-51.4.

Frequently Asked Questions

Do I need a permit to replace a furnace in my Cincinnati house?
Not for the electrical connection if it's a replacement gas or oil furnace, boiler, heat pump, or AC unit connected to existing branch circuits in a one-, two-, or three-family dwelling. CBC § 1101-17.4 exempts that specific replacement work from the separate electrical permit requirement.
Who approves electrical work in Cincinnati before I can use it?
The electrical inspection agency. Under CBC § 1101-19.6, it's unlawful to supply current to any electrical system in a building or structure until the required inspections and approvals from that agency have been completed.
Is a plumbing permit the same as an electrical permit in Cincinnati?
No. CBC § 1101-17.3 lists electrical work and plumbing as separate branches of work, each requiring its own distinct permit that is not folded into a general building permit.
