Cincinnati, OH Building Safety: Electrical Permits (2026)

Under Cincinnati Building Code (CBC) § 1101-17.3, electrical work is one of the branches of work that requires its own permit separate from any building permit, alongside sprinkler equipment, elevators, plumbing, excavation/fill, and mechanical equipment. § 1101-17.4 spells this out for electrical work specifically: separate and distinct permits are required as set out in §§ 1101-17.4.1 (wiring, installation or repair of any permanent electrical wiring, including extensions to existing wiring) and 1101-17.4.2 (equipment, installation or alteration of any electrical equipment or electrical service equipment). There is a narrow 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 do not trigger the separate electrical permit requirement. § 1101-19.6 restates the substantive prohibition: electrical wiring or equipment may not be installed within or on any building, structure, or premises, and no alteration may be made to an existing installation, without first securing approval from the electrical inspection agency.

It is unlawful to use or permit the use of, or to supply current for, an electrical system unless the required inspections and approvals have been made. Applications for electrical permits must be made in writing on forms prescribed by the electrical inspection agency, and for new structures or additions (outside R-3, R-4, R-5 use groups) three sets of scaled plans must accompany the application under § 1101-19.6.1. The director of buildings and inspections or the electrical inspection agency examines applications within a reasonable time; if the work appears code-compliant and safe, the permit is approved, and if not, the rejection or delay is communicated in writing to the applicant per § 1101-17.2.
