Work you can do without a permit

AC 28-105.4 clarifies work that is exempt from a permit. Exemptions from permit requirements of this code shall not be deemed to grant authorization for work to be done in any manner that violates the provisions of the code, including the Zoning Resolution or any other law or rules enforced by the Department. Such exemptions shall not relieve owners of the obligation to comply with the requirements of other city agencies, including any filing requirements. Unless otherwise indicated, permits shall not be required for the following:

Licensed Electrician

A new installation, alteration, or repair of electric wires, wiring apparatuses and appliances or equipment shall be performed by a New York City licensed Electrical Contractor. All electrical work such as, but not limited to, installing conduits, wires, lighting fixtures and switches, panelboards, fire alarm devices, boiler line voltage work and controls, etc., require an electrical permit before commencing such electrical work.

The Electrical Contractor shall coordinate with the Registered Design Professional (RDP), other members of the design team, and all other construction trade contractors where projects have other aspects to the work in addition to electrical. For such projects, the Department only requires the submission of a separate electrical permit application. When an electrical permit application by the Licensed Electrical Contractor includes a large electrical installation (see classifications of large installations under electrical plan examination listed below) or requires Energy Conservation Code (ECC) compliance, such electrical permit application must reference the general project application number for permit issuance.

Electrical construction documents are not required to be submitted by a Registered Design Professional to the Department as part of the electrical or general permit application, except electrical construction documents must be submitted to the Department to obtain an electrical permit as follows:

Electrical Plan Examination - submitted by either a Registered Design Professional or a Licensed Electrician

Any addition to an existing installation which would bring the total to 1000 KVA or greater.

Please note this is in addition to other construction document submittal requirements required for ECC Plan Examination; please refer to NYCECC C406.3 & C406.4, and Table C405.5.2(2) for these requirements.

Fire Department Requirements - Construction documents, prepared by a Registered Design Professional, shall be part of the project submittal for new installations or alterations of an existing fire alarm system. Review shall be performed by an FDNY Plan Examiner.
