Any electrical installation in a new building will need electrical permits. Similarly, all electrical renovations are also going to need permits. Your certified electrical contractor can apply for the permit on your behalf. In some cases, the building owners can also apply for the permits. Homeowners, residing or intending to reside in the building, can also apply for the electrical permits themselves. However, commercial building owners will have to apply for the permits through their electrical contractors. The application requirements are going to vary for both homeowners and commercial building owners.

Electrical Plan Check Requirements
If you are constructing a new commercial building, it will be required to submit a complete electrical plan. Some of the key requirements of such an application include:

  • Building plans, equipment details, and specifications
  • Wiring diagrams that include main, subfeed, and branch circuits
  • Indicating all fixtures, load centers, junction boxes, and main panels using standard symbols
  • Indicating all the materials used for panels, supports, raceways, service entrance, and other items for running the wires
  • Demonstrate compliance with latest energy standards
  • Indicating grounding system

Providing load schedule including disconnection and over-current protection systems, and voltage or ampere configurations

If you are remodeling the building or making additions, it may also be required to distinguish between current and new job. It may also be required to indicate the electrical elements which are affected by new job.

Residential Electrical Check Requirements
If you are a homeowner, you may apply for electrical permits on your own. Since, an electrical contractor will be working on your project, it will be best to let them handle this aspect. The basic application requirements include proof of ownership, your ID, and the estimated cost of the job.

General Wiring Tips
When it comes to wiring your building, it is important to follow certain standards and requirements to ensure optimal safety. For example, electrical services cannot be energized except when there has been an inspection and labeling. There are many other rules to be followed when it comes to your electrical projects. This includes:

  • Underground Inspections: Any underground inspections should be notified to the authorities for inspection.
  • Breaker Termination: It is not recommended to install and terminate breakers on the rough-in phase of construction. Avoiding this can help prevent contacts with energized wires and flashes in outlets.
  • Flood Plain: In case of any installation in a flood plain, it is important that the main electrical service is always installed above the flood level. Your contractor can help you determine whether your building is on a floodplain or floodway.
  • Main Service Panelboard: If a service panelboard doesn't have main disconnection device, it is not possible to add sub-panels.

Separate Permit Requirements for Different Buildings
Separate permits are required for different types of buildings. For example, if it is commercial building the base building and tenancy spaces are going to require separate permits for electrical works. When it comes to multi-family buildings, the permit may cover the base building and all the individual dwelling units. But there can be variations depending on the access to each dwelling.

Thus, the permit requirements for your electrical projects can vary depending on many factors. It is best to let your electrical contractor handle it to save you all the hassles.
