Apartment security is a different problem than house security — and mostly an easier one. One main door, a handful of windows, and package theft usually matter more than backyard coverage. That means a smaller, cheaper kit does the job, as long as it installs without drilling and moves out when you do. Here’s how to protect an apartment in 2026.

What apartments actually need

  • Studio / 1BR: one door sensor on the entry, one motion sensor covering the main room, and the base station. That’s genuinely it for most units — about $150–$250 of hardware.
  • 2BR+ or ground floor: add window sensors on accessible windows and a second motion sensor. Ground-floor and garden units carry most of an apartment building’s break-in risk.
  • Package theft: an indoor camera pointed through your own peephole zone or a video doorbell — but doorbells that replace building hardware usually need landlord sign-off first.
  • Upper floors: your entry door is ~90% of the risk. Don’t overbuy sensors; put the budget into a better door sensor setup and a camera.

Best apartment systems in 2026

SimpliSafe — the best all-round apartment alarm: peel-and-stick everything, sized kits, and no-contract professional monitoring around $20–$30/month you can pause between leases. Ring Alarm — best value bundle if you also want a doorbell camera. Eufy — best with no monthly fee at all; recordings live on the local hub, not a paid cloud. Full comparison in our best wireless security systems ranking, and the $0/month route is covered in our no-monthly-fee guide.

The landlord question

Damage-free devices inside your own unit rarely need permission — nothing is altered, so most leases have nothing to object to. The exceptions: anything drilled, anything in shared hallways, and doorbell swaps. Our renter’s security guide covers lease rules and the ask-in-writing approach in detail.

Renter mistakes to skip

Don’t mount a camera facing a shared hallway — that’s the fastest way to a building complaint. Don’t sign multi-year monitoring for a 12-month lease. And don’t skip the door sensor to buy a fancy camera: the camera shows you the break-in, the sensor’s siren is what stops it.

Frequently asked questions

Can I install a security system in an apartment without landlord permission?
Usually yes for damage-free wireless systems inside your unit — adhesive sensors and freestanding cameras don’t alter the property. Drilling, hallway-facing devices, and doorbell replacements are the cases that need approval. Always check your lease.
What’s the best security system for an apartment?
SimpliSafe for a full no-contract alarm, Ring Alarm if you want a doorbell camera in the bundle, Eufy if you want no monthly fee. All install with adhesive in under an hour.
Are ground-floor apartments riskier?
Yes — ground-floor and garden-level units see most of a building’s break-in attempts because windows are reachable. If you’re on the ground floor, add window sensors; upstairs, your entry door is the overwhelming priority.
How much does apartment security cost?
A studio or 1BR is typically $150–$250 in one-time hardware, then $0/month self-monitored or roughly $20–$30/month for no-contract professional monitoring.
