How to Get a Low Voltage License in Sacramento

Introduction

Low voltage systems are vital to Sacramento’s expanding technology, construction, and security industries. From structured cabling and access control systems to CCTV and fiber optic installations, demand for qualified low voltage contractors is higher than ever.

However, before taking on low voltage projects in Sacramento, California law requires you to hold a C-7 Low Voltage Systems Contractor License issued by the Contractors State License Board (CSLB). This guide explains every step of the process — from meeting the eligibility requirements to passing the state exam — so you can confidently earn your license and start operating legally.

Understanding the C-7 Low Voltage Systems Contractor License

The C-7 license is a specialty classification under the California Contractors State License Board (CSLB) that authorizes contractors to install, service, and maintain all systems that operate on 91 volts or less.

In Sacramento, C-7 license holders typically work on:

  • Structured cabling and network wiring
  • CCTV and security camera systems
  • Fire alarm signaling systems
  • Access control and door entry systems
  • Intercom, paging, and audio/visual systems
  • Fiber optic cabling and data backbone installations
  • Low voltage lighting or building automation controls

The C-7 classification ensures only trained and qualified professionals handle systems critical to building safety, communication, and performance.

Who Needs a Low Voltage License in Sacramento?

You need a C-7 Low Voltage Systems Contractor License if you:

  • Perform low voltage installations valued at $500 or more (labor and materials combined).
  • Advertise or contract for low voltage work in any part of California, including Sacramento County.
  • Subcontract or supervise low voltage technicians on commercial, industrial, or residential projects.

Operating without a license can result in fines, cease-and-desist orders, and loss of credibility in Sacramento’s competitive contracting market.

Step-by-Step: How to Get a Low Voltage License in Sacramento

Step 1: Meet the Basic Requirements

To apply for a C-7 license, you must:

  • Be at least 18 years old
  • Have a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN)
  • Possess at least 4 years of journey-level experience in low voltage systems within the past 10 years
  • Demonstrate experience in installation, maintenance, and troubleshooting of low voltage systems

Your experience must be verifiable — meaning you’ll need a former supervisor, employer, or client to confirm your work history.

Step 2: Submit the License Application

Apply directly through the California Contractors State License Board (CSLB) either online or by mail.

You’ll need to complete and submit:

  • Application for Original Contractor License (Form 13A-1)
  • Documentation of your qualifying experience
  • Application fee (currently around $450)

Mail your completed packet to:
Contractors State License Board
P.O. Box 26000, Sacramento, CA 95826

The CSLB will review your application and notify you if it’s approved or if more information is required.

Step 3: Pass the Required Examinations

Most applicants must take and pass two exams:

  • Law and Business Exam – covers contract law, safety, accounting, employment, and licensing rules
  • Trade Exam (C-7: Low Voltage Systems) – covers technical knowledge about low voltage systems, codes, and installation practices

Exam details:

  • Format: Multiple-choice
  • Testing centers: PSI Testing Centers throughout California (including Sacramento)
  • Passing score: Typically around 72%

The CSLB provides a Candidate Information Bulletin to help you prepare for both sections. Common Low Voltage Installation Mistakes in Sacramento

Step 4: Undergo Fingerprinting and Background Check

Once your application is approved and you’re scheduled for the exam, you’ll need to:

  • Submit Live Scan fingerprints for a background check through the Department of Justice (DOJ) and FBI.
  • Pay the required fingerprinting fee (around $49–$60, depending on the site).

You cannot receive your license until the background check clears.

Step 5: Pay License Fees and Obtain a Bond

After you pass the exams and background check:

  • Pay the initial license fee (currently $200).
  • Obtain a $25,000 contractor bond issued by a surety company licensed in California.

This bond protects consumers from financial loss in case of poor workmanship or contract violations.

Step 6: Receive Your C-7 License

Once you’ve completed all the requirements, CSLB will issue your official C-7 Low Voltage Systems Contractor License. You’ll then be legally authorized to contract for low voltage work anywhere in California, including Sacramento.

Additional Tips for Sacramento Applicants

  • Take a preparatory course – Several trade schools in Sacramento, such as Contractors State License Schools (CSLS), offer C-7 license prep courses.
  • Keep records of all your projects – Detailed records help verify your work experience when completing your application.
  • Stay compliant with city and county rules – Sacramento County may require business registration, zoning approval, and local permits.
  • Renew your license on time – CSLB licenses are valid for two years and must be renewed to remain active.

Maintaining Your License

Once licensed, you must continue to follow CSLB regulations, including:

  • Displaying your license number on all advertising and contracts
  • Maintaining valid workers’ compensation insurance if you have employees
  • Updating your business name, address, or ownership details promptly
  • Renewing your license every two years with the renewal fee

Regular compliance ensures you stay in good standing and avoid fines or license suspension.
