Granny Flats need separate-space security that covers doors, windows, equipment, privacy, and remote alerts without forcing a full traditional alarm package.
2026 setup checklist
- Entry sensors: cover exterior doors, connecting doors, windows, and storage areas.
- Cameras: use privacy zones, schedules, night view, and clear clip-storage rules.
- Smart access: use temporary codes, activity logs, access expiry, and fast removal.
- Backup alerts: compare siren behavior, battery backup, cellular backup, and emergency contacts.
- Cost: model hardware, monitoring, clip storage, batteries, mounts, and extra sensors over 3 years.

Granny flats need a smaller security plan than a full detached house, but the access decisions can be more sensitive. Start with the door people actually use, then decide whether alerts should go to the resident, the main-house owner, or both.
Use the duplex security guide for shared-property layouts, the row-house security guide for tight entry placement, and the basement apartment security guide for secondary-unit coverage. If Apple Home is the control layer, compare HomeKit security systems for duplexes. For no monthly plan setups, review no-subscription home security systems.
