CORRECTION: Alarm-system installation in Nevada is licensed under Nevada Administrative Code 624.200 (State Contractors Board) — classes C-2d (low-voltage systems, fiber, or systems under 91 volts) and C-2c (fire detection). Not NRS 648. NRS 648 licenses private investigators, patrol officers, guards, and paid consultants — none of them alarm installers. Monitoring is licensed separately at the local level: Clark County Code Title 6, Chapter 6.76 (Electronic Security Systems); City of Las Vegas Chapter 6.18. Verify a Las Vegas alarm installer by (1) confirming their NSCB license number and C-2d or C-2c classification on nvcontractorsboard.com license search, (2) confirming the monitoring company holds the local business license.
Correction notice, September 2026: The original June 8 version of this article miscategorized Nevada's alarm-installation licensing framework. Alarm installation licensing is Nevada State Contractors Board classifications C-2d (low-voltage systems) and C-2c (fire detection), administered under NAC 624.200 — not NRS 648. NRS 648 governs private investigators, private patrol officers, security guards, and paid security consultants, none of which are alarm installers. See our detailed September 4 guide for the accurate license-verification workflow.
Sources cited in this article: NAC 624.200 (Nevada State Contractors Board classifications C-2d low-voltage systems, C-2c fire detection); Clark County Code Title 6, Chapter 6.76 (Electronic Security Systems, local monitoring license); LVMC Title 6, Chapter 6.18 (City of Las Vegas parallel).
The original version of this article, published June 8 2026, incorrectly stated that Nevada Revised Statutes Chapter 648 licenses alarm-system installers. It does not. This corrected version supersedes that content. Any external site linking to the June 8 article now reaches the accurate framework below.
Alarm-system installation in Nevada is licensed by the Nevada State Contractors Board (NSCB) under Nevada Administrative Code 624.200. Two contractor classifications apply:
NRS Chapter 648 is administered by the Nevada Private Investigators Licensing Board (PILB). It licenses six occupations:
None of those categories cover alarm installation, monitoring, or servicing. If an installer's company also runs guard-response services, that guard side does need NRS 648 coverage — but the installation itself is a Contractors Board matter.
For the full deep-dive on the license stack — including the specific NAC 624.200 code sections, the Clark County Code Chapter 6.76 monitoring requirements, and the differences between city jurisdictions — see the September 4 guide on the Las Vegas alarm installer license stack.
Yes. The June 8 version stated that NRS Chapter 648 licenses alarm installers in Nevada. That was incorrect. NRS 648 covers private investigators, private patrol officers, security guards, process servers, repossessors, dog handlers, and paid security consultants. Alarm-system installation licensing lives at the Nevada State Contractors Board under NAC 624.200 — classifications C-2d (low-voltage systems, ≤91V or fiber) and C-2c (fire detection). We're leaving this article live at the same URL rather than deleting it, and rewriting the content, so that anyone who visited or bookmarked the earlier version reaches the correct information.
The Nevada State Contractors Board maintains a public license search at nvcontractorsboard.com. Enter the contractor's name or license number. A legitimate alarm installer should show at minimum a C-2d classification (low-voltage systems). Fire-alarm installers should also carry a C-2c. Both classifications must be active. The record also shows any disciplinary history.
Monitoring is licensed locally, not by the State Contractors Board. In unincorporated Clark County (LVMPD jurisdiction), the operative code is Clark County Code Title 6, Chapter 6.76 — Electronic Security Systems. In the City of Las Vegas, it's LVMC Chapter 6.18. Henderson, Boulder City, North Las Vegas, and Mesquite each have their own city licensing. Ask the monitoring company for their local business-license number and verify it on the relevant city's business-license portal.
Only tangentially. If the installer's company also provides guard-response services (someone shows up to a triggered alarm), that guard service is licensed under NRS 648.014 (private patrol officer). Standard alarm installation, monitoring, and central-station work are not covered by NRS 648. Most Nevada alarm companies do not offer in-house guard response and outsource it if needed.
