Intercom Permit Requirements in Los Angeles, California

Installing an intercom system in Los Angeles? Good news - most intercom installations do NOT require permits. This guide covers when permits are needed, California CSLB licensing requirements, and best practices for intercom installations in LA County.

Quick Answer: Do You Need a Permit?

Most intercom installations do NOT require permits in Los Angeles. Standalone audio or video intercom systems operating on low voltage (Class 2 wiring) are generally exempt from electrical permits under the California Building Code.

When Permits ARE Required

Fire Alarm Integration

• Intercoms tied to fire alarm systems require fire alarm permits
• Emergency voice/alarm communication systems (EVACS)
• High-rise building emergency communication

Access Control Integration

• Intercoms integrated with electronic door locks
• Systems that control magnetic locks or electric strikes
• Gate access systems at multi-family properties

New Construction

• Intercom wiring as part of new building electrical plans
• Commercial tenant improvements requiring plan review
• LADBS plan check required for major installations

Electrical Work

• Installing new electrical outlets or circuits
• Any work involving line voltage (120V+)

Permit-Exempt Intercom Work

• Wireless video doorbell systems (Ring, Nest, etc.)
• Plug-in audio intercoms using existing outlets
• Battery-powered intercom units
• Low-voltage wired intercoms not integrated with other systems
• Replacement of existing intercom equipment
• Class 2 low-voltage wiring installations

California CSLB Contractor Licensing

California requires proper licensing through the Contractors State License Board (CSLB):

C-7 Low Voltage Systems License

The C-7 classification covers low voltage systems:

• Scope: Installation of communication and low-voltage systems
• Requirement: Pass trade exam and law/business exam
• Experience: 4 years journey-level experience
• Bond: $25,000 contractor bond required

If work involves electrical circuits beyond low voltage:

• C-10 electrical license required
• Permits must be pulled through LADBS

Alarm Company Operator License

If integrated with alarm systems:

• BSIS Alarm Company Operator license required
• Additional employee registration requirements

Video Intercom vs. Audio-Only

Video Intercom Systems

• Same low-voltage exemptions as audio intercoms
• No additional permits for camera functionality
• High demand in multi-family and gated communities

Audio-Only Intercoms

• Generally the lowest regulatory burden
• Common in apartment buildings

Multi-Family and Commercial Considerations

Los Angeles has specific requirements for larger properties:

• ADA compliance for building entrance intercoms
• High-rise buildings may have additional requirements
• Historic properties may need design review

Best Practices for LA Intercom Installations

• CSLB license required: All work for compensation needs licensing

• ADA compliance: Ensure accessible design for building entrances
• Test thoroughly: Verify audio/video quality
