New Jersey Rehab code?

[mtnelectrical]

I have a customer, multifamily building owner, maybe 30 units. He wants to renovate the kitchen of one the units completely.There are 2 20 amps circuits existing in the kitchen.it seems they were run some year ago. They redoing everything and relocating everything. Could we considered it a new kitchen and with that do we need to run more home runs for range hood circuit, refrigerator, etc? or could we just use this existing circuits to feed everything?

Under the NJ Rehab Code you can strip off the sheetrock down to the studs and you are not required to add any new circuits. You can relocate appliances and re-use the same circuits. However, if you are adding receptacles or lighting loads to existing circuits you may have to provide the EI with load calculations and/or wiring diagrams. If you are adding any new circuits (i.e. microwave, exhaust hood that requires a dedicated circuit, sub-zero refer, etc.) then you will have to abide by the current Codes. Also, if you change the foot print or elevation of a structure then you are subject to the most recent Codes adopted by that jurisdiction and you cannot use the Rehab Code for that portion.

For any part of the addition you would have to abide by the current code, but readers should be aware that this doesn't trigger a global upgrade to the entire structure for code compliance. Unless you go over 50% of the current square footage.

That is correct. I forgot the 50% part. Good pick-up

Where are you getting the 50% requirement?

There are any number of areas in the subcode containing "When the work area exceeds 50 percent of the gross enclosed floor area of the building..." it goes on to require alarm systems, sprinklers, vertical opening protection, elevator modification, etc depending on the occupancy. I'll concede it doesn't appear to require that the electrical system, for example, would have to be completely redone.

If the amount of work is sufficient to qualify as reconstruction then a laundry circuit is required and smoke detectors but outside of that not a hole lot.

I'd like to retract this statement as it is incorrect. I was thinking about requirements for smoke alarms. My original statement is correct. You can gut the sheetrock in the house down to the studs and you would still fall under the Rehab Code. You can reuse and relocate existing wiring within the kitchen and you are not required to make it AFCI protected. However, any new wiring (like a microwave, dishwasher, etc.) would have to be AFCI if you are under the 2014 Code (which we are not yet in NJ)
