A low voltage contractor in Westchester County, NY works under a different licensing system than one in New York City. Westchester licenses electricians at the county level, the state licenses camera and alarm installers, and each city, town or village runs its own building department. Low voltage wiring in Westchester County, NY, from a Cat6A run in a White Plains office to card readers in a Yonkers apartment lobby, still comes down to the same buyer checks: the right license for each system, insurance on file, and a scope every bidder prices the same way.
This guide is for facilities managers, IT leads, owners and GCs scoping commercial, multifamily or institutional work in Westchester and the lower Hudson Valley. It covers which licenses apply, how to check them, how to scope each system, and what to send for pricing. Official sources were checked October 13, 2026. For the regional overview, see our Westchester and Hudson Valley low voltage contractors page.
Who can do electrical and low-voltage work in Westchester
Westchester County, not the individual municipalities, licenses electricians. The county’s Electrical Licensing Board issues Master Electrician and Special Electrician licenses (plus Electrical Inspector licenses), and the county code states that local municipalities are no longer responsible for licensing master electricians. A Special Electrician is licensed for one particular building or plant, not for contracting work across the county. Westchester County Code Article XVII.
Two points matter for low-voltage buyers:
- The county’s definition reaches signaling. Article XVII defines a master electrician as anyone who installs, extends, alters or repairs wiring and equipment for light, heat, cooling, power purposes “or for signaling systems.”
- No one may contract for that work without the license. Under §277.702, no person may perform, offer or contract to perform the work of a master electrician in the county unless licensed by the board or working under the supervision of a licensed master electrician. The listed exemptions cover things like plugging appliances into existing circuits, elevator maintenance and utility line work, not building cabling.
The county’s own hiring advice is blunt: all electrical work must be performed by a Westchester County-licensed electrician or an employee of one. Westchester Consumer Protection hiring tips. Whether a given data or camera run also needs a municipal permit is a question for the building department in your city, town or village, so ask the bidder which permits they plan to pull and from whom.
The rest of the Hudson Valley is not covered by Westchester’s board. For a site in Rockland, Putnam, Dutchess, Orange or Ulster, ask the local building department which electrical license it accepts before you compare bids.
Camera, alarm and access work also needs a state license
New York’s General Business Law Article 6-D requires a Department of State license to engage in the business of installing, servicing or maintaining security or fire alarm systems. The Department’s regulations (19 NYCRR Part 195) apply that to a CCTV or video surveillance system used to detect or monitor intrusion, break-in, theft, movement, sound or fire, and to electrical entry systems that detect or signal intrusion. Card access on a single door, with no intrusion detection or signaling, falls outside the rule. NY DOS Article 6-D and Part 195.
Instead of the alarm license, a licensed master electrician can register a waiver with the Department of State, valid only in the municipality that issued the electrician’s license. Licensees must state “Licensed by the N.Y.S. Department of State” in advertising and on documents, with their identification number on documents. The state’s Licensee Search lists alarm installer licenses, but only active ones.
How to check a Westchester low voltage contractor before award
Run these checks on the firm that signs the contract and on any subcontractor doing licensed work:
- County electrician license. Look up the master electrician in the county’s Trade Licenses Search. The record shows the license expiration and, through the details links, the expiration dates of the workers’ compensation and general liability policies on file. The county also tells consumers to ask to see the license card. Westchester trade licenses.
- State alarm license. For cameras, intrusion detection or multi-door access, confirm the Article 6-D license or the electrician’s waiver registration through the Department of State.
- Who holds what. If the bidder is a cabling firm that subcontracts electrical scope, get the electrician’s name and county license number in the proposal.
- Permits. Ask which municipal permits the work needs and who will file them.
- Insurance wording. Match the certificate to the owner’s or managing agent’s required wording before mobilization.

Scope by system
Each system below links to the page that covers Westchester and Hudson Valley projects.
- Structured cabling and network cabling: Specify the cable category, telecom-room location, test standard and labeling scheme. In an occupied office park, say which closets and ceilings are shared with other tenants. Pricing context is in our structured cabling cost guide.
- Access control: Separate standalone card readers from doors tied to the fire alarm or egress hardware, and from systems that signal intrusion, because those can change which license applies. The access control cost guide covers system types.
- Commercial security cameras: List interior and exterior locations, garage levels and retention needs, and confirm the state alarm license above. See the security camera cost guide.
- DAS and in-building coverage: Treat public-safety radio coverage and tenant cellular coverage as two scopes. Ask your local fire official what the building needs for emergency responder radio before you price cellular.
- Commercial AV and Wi-Fi: Give bidders room counts, ceiling types and the access-point layout you want surveyed.
- Fiber: Ask who owns the building entrance, the riser or campus path and the carrier coordination.
Area context: The Ibex at Ridge Hill, Yonkers
New construction shows the kind of low-voltage scope Westchester projects now carry. This is area context only, not an LVNY project.
In early October 2026, Saber-Hightower, Rafferty Real Estate and Eagle Realty Group started construction on The Ibex, a 17-story mixed-use building at Ridge Hill in Yonkers, with Bank OZK providing construction financing. Westfair reports 282 rental apartments (28 of them affordable), about 5,000 square feet of ground-floor retail, resident parking in Ridge Hill’s existing garage, and amenities including co-working space, a fitness center and a 17th-floor sky lounge. The developer’s application to the Yonkers IDA estimated the cost at $144.7 million and the build at 30 months. Westfair, October 7, 2026. WRE News reports first occupancy expected in late 2028. WRE News, October 7, 2026.
For owners and GCs planning similar multifamily or mixed-use buildings, the Division 27 and 28 packages typically include riser and unit cabling, lobby and garage access control, cameras, amenity AV and Wi-Fi, and a coverage check for a tall building. Our Yonkers page covers the city.
Where Westchester projects differ
The county has dense downtowns (White Plains, New Rochelle, Mount Vernon), corporate and campus sites (such as Tarrytown) and river towns like Peekskill. Because permits are municipal, two sites a few miles apart can have different filing steps and inspection timing. Find out at the start whether public funds are involved, since covered public work brings New York prevailing-wage obligations; our prevailing wage guide explains how coverage is decided. Owners and managing agents set their own insurance wording, work hours and labor requirements, so collect those before asking for prices.

- Target start and handover dates, and who signs off the finished work
Frequently asked questions
Does a low voltage contractor in Westchester need a county license?
Westchester’s electrical licensing law defines master electrician work to include wiring for signaling systems and bars anyone from contracting for that work without a county license or supervision by a county-licensed master electrician. Ask each bidder who holds the county license for the job and check it in the county’s Trade Licenses Search.
Does a camera installer need a New York State license?
When cameras detect or monitor intrusion, theft, movement, sound or fire, the Department of State counts the system under Article 6-D, which means the installing business needs the state license or, for a master electrician working in the municipality where licensed, a registered waiver.
Are the rules in Westchester the same as in New York City?
No. New York City licenses electricians through its Department of Buildings and has its own low-voltage provisions; Westchester licenses electricians through the county and permits through each municipality. The state alarm license applies in both. Our Bronx contractor guide covers the city rules.
Can a single Westchester contractor take on cabling, cameras and access control?
Yes, if the firm holds the credentials each part requires. Ask the bidder to name who holds the county electrical license and the state alarm license for the job.
Is Low Voltage New York the contractor?
No. Low Voltage New York scopes each project and matches it with a licensed, insured partner crew from our statewide network, union or non-union. Before signing, run the license checks above on whichever contractor is matched. Crews in our network work across Westchester and the Hudson Valley.
