How to Apply for the City of Los Angeles Police Alarm Permit

If you own or operate an alarm system in Los Angeles, you need a Los Angeles police alarm permit from the City of Los Angeles Office of Finance before the system can legally be active. The initial permit costs $45, and you can apply online at latax.lacity.org/policepermitapp, by mail, or in person at any Office of Finance branch.¹ The permit then renews every year on December 31 for $26.²

Who Needs One

Los Angeles Municipal Code Section 103.206 prohibits anyone from installing, activating, or operating an alarm system without a valid permit.³ That covers residential and commercial properties alike, and it applies whether your system sounds an audible siren on-site or sends a silent signal to a professional monitoring station. If the property is inside city limits and has any burglar, holdup, or panic alarm, the permit is required.

Operating without one is a misdemeanor under the city’s alarm ordinance.³ If LAPD responds to a false alarm at an unpermitted address, you are billed the standard $219 false alarm fee plus a $100 penalty, with the penalty climbing by $100 for every additional false alarm in a 365-day period.⁴ One unpermitted false alarm costs $319, which is more than six times the price of the permit itself.

What to Gather Before You Apply

Have everything below ready before you open the application. Mismatched or missing details are the most common reason a submission stalls.

Your full legal name and daytime contact information. The name on the permit must match the property owner or an authorized tenant.
The exact street address of the alarm site. The online portal will ask you to confirm the address falls within Los Angeles city limits at neighborhoodinfo.lacity.org before you can continue.
A separate billing or mailing address if it differs from the alarm site, so renewal notices reach you.
Two emergency contacts, each with a name and phone number. These should be people who can physically respond to the property when you cannot.
Your alarm company’s name, address, phone number, and city-issued business permit number. The city uses this to confirm the monitoring company is itself properly licensed.

Verify the alarm company’s permit number before you submit. If it is wrong or the company’s license has lapsed, the Office of Finance may hold the application while it checks.

How to Apply

Online

The fastest option is the city’s portal at latax.lacity.org/policepermitapp. The site first asks you to confirm your address is inside city limits, then walks you through a short series of screens. You enter the information above and pay the $45 fee by credit card or electronic check.¹

In Person

Any Office of Finance branch will accept an application if you arrive before 3:00 p.m.¹ Bring the same information you would need for the online form. Branch locations and hours are posted at finance.lacity.gov.

By Mail

A printable application is available on the Office of Finance alarm permits page. Fill it out, enclose a check or money order for $45 payable to the City of Los Angeles, and mail both to the address printed on the form. Mail submissions take longer than online or in-person filings, so leave extra time before you expect the system to be active.

Fees and What You Pay Each Year

Initial permit: $45
Annual renewal: $26

Both figures come from the Office of Finance fee schedule, and the amount is the same for residential and commercial accounts.¹ Online payments go through by credit card or electronic check; mailed payments must be a check or money order.⁴

Every permit expires on December 31 and must be renewed each year.² The Office of Finance mails renewal notices toward the end of the year, but mark your own calendar rather than relying on one arriving. If the permit lapses and a false alarm occurs, you are billed at the unpermitted rate.

Permits attach to a specific person at a specific address. Move to a new place inside Los Angeles and you need a brand-new permit for the new address. When a property changes hands, the incoming owner has to apply fresh, because the previous owner’s registration does not transfer.

What False Alarms Cost With a Permit

Even with the permit in good standing, LAPD responses to false alarms carry escalating fees. The current base fee of $219 took effect on October 20, 2025.⁴ For permitted users:

1st false alarm: $219
2nd false alarm: $269
3rd false alarm: $319
4th false alarm and beyond: $369 or more

Without a valid permit, add $100 to the first incident and another $100 for each additional false alarm in the same 365-day window.⁴ A second unpermitted false alarm in one year works out to $269 plus $200, or $469.

Keeping False Alarm Fees Down

Most false alarms come from user error: entering through the wrong door, forgetting the code, or failing to disarm in time. A few habits keep ongoing costs at zero.

Train everyone in the household. Family members, roommates, and regular visitors should all know how to arm and disarm the system.
Secure doors and windows. Loose or rattling frames can trigger motion and contact sensors.
Keep the monitoring company’s number handy. If you trip the alarm by accident, calling right away can cancel the dispatch before LAPD is sent.
Maintain the equipment. Dead sensor batteries and aging wiring cause phantom triggers; replace batteries on a schedule and have the system inspected yearly.

If you are buying or upgrading a system, ask the alarm company about panels that meet the ANSI/SIA CP-01 standard. They are built to reduce user-error false alarms through longer exit delays and more forgiving re-entry sequences.
