ADT Home Security in Ontario, Installed by a Local Team You Can Trust
Your Home Safety designs and professionally installs ADT-monitored security systems for Ontario homeowners — from the brand-new homes of Ontario Ranch to the established neighborhoods around downtown and Euclid Avenue. Honest advice, same-day installation options, and a local Inland Empire team that actually answers the phone.
Security That Fits How Ontario Actually Lives
Ontario is two cities in one. In Ontario Ranch and New Haven, huge new master-planned communities are filling with first-time buyers who want their homes protected from the first night — doorbell cameras, smart locks, and sensors on every door, installed before the boxes are even unpacked. Moving in is the single best time to secure a home, and new construction makes it easy to cover everything cleanly.
In older Ontario — the neighborhoods around downtown and Euclid Avenue — homes from the early 1900s through the postwar years get the wireless treatment: full protection without tearing into original walls and woodwork. Many of these homes have had an alarm at some point, sometimes an ADT system a previous owner left behind that we can reactivate or upgrade instead of starting from scratch.
Either way, you get the same thing: a walkthrough of your actual home, straight answers about what you need (and what you don’t), and an install handled by the local team — not a subcontractor shipped in from somewhere else.

“Hands down, Joseph Lopez is the best at what he does… At first I wasn’t going to go with ADT for our security needs, but after speaking with Joseph, I knew ADT was the way to go. Thank you, Joseph!”

Before You Decide
How much does an ADT system cost?
It depends on your home and the equipment you choose. Many customers qualify for $0 upfront on their equipment and installation, with monthly monitoring based on the protection level they pick. Your free quote gives you exact pricing for your home — no guessing and no pressure.
There’s already an ADT system in my home. Can you reactivate it?
Very often, yes. If the previous owner left ADT equipment behind, we can inspect it for free, reactivate what works, and upgrade what’s outdated — usually for much less than a brand-new system.
How fast can you install?
Faster than you’d expect: same-day installation is available on many systems when you contact us early and a crew is working in your area — it’s one of the advantages of a local dealer. If today doesn’t work out, we’ll get you scheduled the same week. Ask about same-day when you call and we’ll tell you straight whether we can make it happen.
Are you ADT, or a local company?
We’re both: Your Home Safety is a locally owned company and an official ADT Authorized Dealer. You get ADT’s nationwide 24/7 monitoring network with a local team that designs, installs, and supports your system.
