House Rewiring NYC — Knob-and-Tube & Full Apartment Rewire

Full & Partial Rewiring for NYC Apartments and Brownstones

NYC has more buildings with outdated wiring than almost any other city in the country. Pre-war construction using knob-and-tube wiring, mid-century aluminum wiring, and 60-amp service panels that can’t power a modern apartment are all common throughout the five boroughs. AE Electric performs full and partial rewiring for NYC apartments, brownstones, and homes — licensed, permitted, and to current NYC electrical code. Call now: (646) 846-0008

Signs Your NYC Home Needs Rewiring

• Knob-and-tube wiring — Used in buildings constructed before 1940. Has no ground wire and uses cloth insulation that dries and cracks over decades. Most insurance companies now refuse to insure properties with active knob-and-tube wiring.
• Aluminum wiring — Used in some buildings from 1965–1973. Aluminum expands and contracts more than copper, loosening connections over time. The Consumer Product Safety Commission considers aluminum wiring a fire hazard.
• Two-wire ungrounded outlets — Two-prong outlets throughout the apartment indicate a 2-wire system with no safety ground. Modern electronics and appliances expect and require grounding.
• 60-amp or 100-amp service on a modern apartment — Inadequate for today’s electrical loads, especially with EV chargers, HVAC, electric ranges, or multiple high-draw appliances.
• Repeated tripping breakers — A sign that circuits are overloaded because the wiring can’t handle the load.
• Insurance company refuses to renew or issue coverage — Increasingly common with knob-and-tube wiring.
• Mortgage lender requires wiring upgrade — Some lenders require wiring upgrades before approving financing on properties with known outdated wiring.

How House Rewiring Works in NYC

Rewiring a NYC apartment or home is a more complex project than in most markets due to plaster walls, DOB permit requirements, and building management coordination. Here’s the typical process:

1. Assessment — We inspect the existing wiring, panel, and service entrance to determine the full scope of work and identify any hidden hazards.
2. Permit filing — All rewiring in NYC requires DOB permits. AE Electric handles all permit applications. Work cannot legally begin without a filed permit.
3. Panel upgrade if needed — Most rewiring projects include a panel upgrade since the old panel is often incompatible with modern wiring standards.
4. Cable installation — New NM-B cable (Romex) or conduit is run through walls and ceilings. In plaster buildings, we use low-impact techniques — fishing cable through walls and drilling through fire stops — to minimize the amount of wall opened.
5. Outlets, switches, and fixtures — All new outlets and switches are installed with proper grounding. GFCI outlets are installed in all code-required locations.
6. DOB inspection — A NYC DOB electrical inspector must inspect and approve the work before the permit closes. AE Electric coordinates this inspection.

NYC-Specific Rewiring Considerations

• Plaster ceilings and walls — Most pre-war NYC buildings have plaster walls, not drywall. Plaster is harder to patch but our electricians are experienced with low-impact techniques that minimize damage.
• Co-op and condo approval — In co-op buildings, electrical work often requires board approval and submission of contractor insurance documentation. We’re familiar with this process.
• Occupied apartments — We coordinate work schedules to minimize disruption to occupants. Power outages during work are typically limited to the unit being rewired.
• Fire stopping — NYC building code requires fire stopping at every floor penetration and at certain intervals in walls. We install proper fire-stop materials as part of the rewiring.

House Rewiring Cost in NYC

Full apartment rewiring in NYC typically ranges from $8,000–$20,000+ depending on the size of the unit, the existing wiring type, wall material, and whether a panel upgrade is included. Partial rewiring — replacing specific circuits or areas — starts from $2,500. Permit fees are included in our quotes. We provide a detailed written estimate after the initial assessment.
