New York Intercom Permit Requirements: State & NYC Licensing Guide
New York has a complex regulatory environment for low voltage work, with requirements varying significantly between New York City, Long Island, and upstate regions. Intercom installation may require different licenses depending on where you work. Here's what contractors need to know.
Quick Answer
New York does NOT have a statewide low voltage license for intercom installation. Requirements are local—NYC has a Low Voltage Installer certification through DOB, Suffolk County requires a Low Voltage Restricted License, and many other areas have no specific requirements beyond general business licensing. However, if the intercom is part of a security/alarm system, you may need a NYS Security Alarm Installer license from the Department of State.
Understanding New York's Licensing Structure
Unlike states with unified statewide licensing, New York operates a multi-tiered system:
| Jurisdiction | License Required | Issuing Agency |
|---|---|---|
| NYS (Security/Fire Alarms only) | Security or Fire Alarm Installer | NYS Department of State |
| New York City | Low Voltage Installer Certification | NYC Department of Buildings |
| Suffolk County | Low Voltage Restricted License | Suffolk County Consumer Affairs |
| Nassau County | Varies by municipality | Local building departments |
| Upstate/Other | Often none required | Check local jurisdiction |
New York City Requirements
NYC has specific regulations for low voltage work through the Department of Buildings (DOB).
Low Voltage Installer Certification
Per NYC Administrative Code §27-3016.1, businesses installing communication, signaling, alarm, or data transmission systems can obtain Low Voltage Installer certification.
Requirements:
| Requirement | Details |
|---|---|
| Age | 18 years or older |
| Experience | 2 years of satisfactory experience in low voltage work |
| Character | Good moral character determination |
| Competency | Determination by commissioner that applicant is competent |
What Is Covered
NYC defines low voltage electrical work as "installation, alteration, maintenance or repair of electrical wiring that is designed to operate at less than fifty volts for signaling, communication, alarm, and data transmission circuits."
This includes:
- Intercom systems
- Data/network cabling
- Telephone systems
- Video systems (non-security)
- Sound/paging systems
What Is Excluded
The Low Voltage Installer certification does NOT cover:
- Life safety systems
- Fire alarm systems (requires Master Electrician + NYS license)
- Work in hazardous locations
- Security alarm systems (requires NYS Security Alarm Installer license)
Permit Requirements in NYC
Per NYC Electrical Code, low voltage electrical work is generally exempt from work permits:
"The provisions regarding electrical work permits shall not apply to low voltage electrical work."
This means basic intercom installations in NYC typically don't require DOB electrical permits, though you still need proper certification and must comply with code.
Long Island Requirements
Suffolk County
Suffolk County has some of the strictest low voltage requirements in the state:
- License Required: Low Voltage Restricted License
- Agency: Suffolk County Consumer Affairs
- Application Fee: $400
- Exam: Restricted electrical test required
- Processing Time: Approximately 6 months
This license is required for:
- CCTV systems
- Intercom systems
- Network/data cabling
- Telephone systems
- Internet broadband
Important: This is in ADDITION to the NYS Security and Fire Alarm Installers License if you're doing monitored security work.
Nassau County
Nassau County requirements vary by municipality. Many towns defer to general contractor licensing without specific low voltage requirements. Check with your specific town or village building department.
Upstate New York
Many upstate cities and counties have minimal low voltage licensing requirements. However, major cities like Buffalo, Rochester, Syracuse, and Albany may have local electrical licensing that includes low voltage. Always verify with the local building department before starting work.
NYS Security Alarm Installer License
If your intercom installation is part of a security system (entry control, access control with alarm integration), you may need the statewide Security Alarm Installer license.
Who Needs This License
Per NYS Department of State, this license is required for anyone who "offers or undertakes, by any means or method, to install, service or maintain a security or fire alarm system."

Frequently Asked Questions
Do I need a license to install intercoms in NYC?
For professional installation, you should obtain the Low Voltage Installer certification from DOB. While enforcement has historically been light for small residential work, larger commercial projects and building management companies increasingly require proof of certification.
Is the NYS Security Alarm Installer license needed for intercoms?
Only if the intercom is integrated with a security/alarm system (access control, intrusion detection). Standalone intercom systems without alarm functionality don't require this license.
Can I work throughout New York with one license?
No. New York's fragmented licensing means you may need different credentials for different areas—NYC, Suffolk County, and individual municipalities all have their own requirements. Many contractors maintain multiple licenses to work across regions.
Why is Suffolk County so strict?
Suffolk County has historically treated all low voltage work—including CCTV, intercom, and data cabling—as restricted electrical work requiring specific licensing, separate from the NYS Security license. This is more stringent than most New York jurisdictions.
