Hiring an Electrician in NYC
A neutral, homeowner-first guide to hiring an electrician in New York City: why the NYC license matters, how to verify it, what jobs need permits, what electrical work costs, and how to find a reliable pro in your borough.
Quick Takeaways
- Electricians in NYC must hold a NYC Department of Buildings license. Always verify it before hiring.
- Most electrical work beyond swapping a fixture or outlet cover requires a NYC permit.
- Pre-war buildings (pre-1938 in NYC) often have outdated wiring (knob-and-tube or 60-amp panels) that needs upgrading before renovations or new appliances.
- Panel upgrades are the most common high-cost electrical job. Get at least 3 written quotes for the same scope.
- An unlicensed or unpermitted job can void your homeowner insurance and create problems when you sell.
- On ServHom no electrician can pay to rank higher, and we surface licensing credentials where we have them.
Start here: how ServHom is different
Most platforms either sell your contact details to a list of contractors or rank whoever pays for placement. ServHom does neither. We surface licensed electricians, show the credentials we hold on file, and never let anyone pay to rank higher.

NYC electrical licensing: what to verify
Unlike most states, New York City has its own electrical licensing system run by the NYC Department of Buildings. There are two main license types:
- Master Electrician (ME): licensed to supervise and take out permits for any electrical work in NYC. This is the license you want for significant jobs.
- Special Electrician (SE): licensed for specific building types or scopes. Less common for residential work.
- How to verify: NYC DOB issues the license and maintains the public record. On a ServHom profile we show the license details and link to the official NYC record so you can check it yourself.
- Insurance: always ask for a certificate of general liability and workers compensation coverage before work starts.
What work requires a permit in NYC
Most electrical work beyond a simple fixture swap or outlet cover replacement requires a NYC Department of Buildings permit. Skipping the permit is not just a code violation - it can void your homeowner insurance and come up during a sale or refinance.
- Always needs a permit: panel upgrades, new circuits, rewiring, new outlets or switches in a new location, installing a subpanel, EV charger installation.
- Usually no permit needed: replacing a like-for-like fixture, swapping an outlet cover, replacing a ceiling fan on an existing circuit.
- If in doubt: ask your electrician to confirm in writing whether a permit is required for your specific job before work starts.
Pre-war buildings and older wiring
A large share of NYC housing stock predates modern electrical codes. If your building was built before 1950, there is a real chance it has knob-and-tube wiring, aluminum branch wiring, or an undersized 60-amp panel. These are not automatic emergencies, but they are worth understanding before you add new appliances, do a kitchen renovation, or install an EV charger.
- Knob-and-tube wiring: an older system with no ground wire, common in pre-1940s buildings. Insurers sometimes require it to be replaced before issuing a policy.
- 60-amp or 100-amp panels: many pre-war apartments and homes were wired for far less load than modern households use. Adding a dishwasher, HVAC, or EV charger often requires a panel upgrade first.
- Always have a licensed electrician assess older wiring before starting any renovation work.
How to choose and vet an electrician
A reliable electrician is easy to verify and clear about scope. The strongest signals are a valid NYC license and a written quote that spells out the work, the permit plan, and the price.
- Confirm the NYC DOB license and current insurance before any work starts.
- Ask who pulls the permit. On a permitted job, the licensed master electrician is responsible.
- Get the scope in writing: the work, the materials, whether a permit is included, and the timeline.
- Be cautious of cash-only quotes, large upfront deposits, or anyone who suggests skipping the permit.
- For panel upgrades or rewiring jobs, get at least 3 written quotes for the same scope.
What electrical work costs in NYC
Costs vary widely by scope: replacing an outlet or fixture is at the low end, while a panel upgrade or full rewire can run from several thousand to tens of thousands of dollars depending on the size of the home, access, and permit fees.

FAQ
Does an electrician need a license to work in NYC?
Yes. Electricians working in New York City must hold a NYC Department of Buildings electrical license (Master Electrician or Special Electrician). This is separate from a state license and is required for permitted work in the five boroughs. Always ask to see the NYC license number and verify it before hiring.
How do I verify an electrician's NYC license?
NYC electrician licenses are public records held by the Department of Buildings. On a ServHom profile we show the license details and link to the official NYC DOB record so you can check the license status and expiry date yourself before you hire.
Do I need a permit to add an outlet or upgrade my electrical panel?
A panel upgrade always requires a NYC permit, pulled by the licensed master electrician. Adding a new outlet in a new location also requires a permit. Replacing an existing outlet like-for-like generally does not. If you are unsure, ask the electrician to confirm in writing - skipping a required permit can cause insurance and resale problems.
My apartment has knob-and-tube wiring. Is that dangerous?
Knob-and-tube wiring is not automatically dangerous if it is in good condition, but it has no ground wire, cannot support modern loads, and some insurers will not cover homes with active knob-and-tube. Have a licensed electrician assess the condition before doing any renovation work or adding appliances.
How much does a panel upgrade cost in NYC?
Panel upgrades in NYC typically run from about $2,000 to $6,000 or more depending on the panel size, the amount of work required to meet current code, permit fees, and building access. Prices vary widely, so get at least 3 written quotes for the same scope and amperage.
