New homeowners usually inherit unknown keys, old garage codes, weak exterior lighting, and a list of doors and windows they have not mapped yet. The first security setup should focus on closing those gaps before buying extra gadgets.
Move-in security priorities
- Reset access first: rekey or replace exterior locks, remove old garage and keypad codes, and audit any smart-home accounts left by the previous owner.
- Map entry points: count exterior doors, ground-floor windows, basement access, sliding doors, garage doors, and detached structures before choosing a kit size.
- Cover package and driveway activity: doorbell and outdoor cameras should verify deliveries, visitors, and vehicle approaches.
- Add environmental sensors: water, smoke, CO, and temperature alerts matter more in the first year because new owners may not know the home’s weak spots yet.
36-month cost checklist
- Starter alarm kit plus the sensors needed for the actual entry-point count.
- Smart locks, garage controller, doorbell camera, outdoor cameras, and storage fees.
- Monitoring, cellular backup, permits, and any false-alarm fees in your city.
- Water leak sensors, smoke/CO listeners, and backup power for the router or hub.
- Battery replacement and expansion hardware after the first six months.
Best setup by home type
- Single-family home: front/back/garage sensors, doorbell camera, outdoor camera, smart lock, leak sensors, and monitored alarm response.
- Townhouse: entry sensors, doorbell camera if allowed, smart lock, and water sensors near shared walls or utility rooms.
- Older home: extra leak/freeze detection, basement coverage, window sensors, and battery backup.

June 2026 update: new-homeowner security setup order
New homeowners should secure the highest-risk access points before buying extra cameras. Start with the front door, back door, garage entry, and any ground-floor windows that are hidden from the street. After that, add a keypad routine, entry-delay rules, and camera coverage for packages or side gates.
If the house has a detached garage or shed, compare this guide with our detached garage security picks. For outdoor access points, use the side gate and fence security guide. Renters moving into a first home should also read the ground-floor apartment checklist because the same door and window priorities apply.
June 2026 move-in update: what new homeowners should add next
New homeowners should start with entry sensors and an arming routine, then fill the gaps by lifestyle: no-subscription monitoring for cost control, HomeKit if Apple Home matters, smart locks for daily access, and side-gate coverage for yard or garage access.
- Cost-sensitive move-in: compare no-subscription security systems for new homeowners.
- Apple Home household: compare HomeKit security systems for new homeowners.
- Access control: use smart-lock apartment guidance as a door-access checklist before replacing hardware.
- Outdoor entries: review side-gate and fence security if the new home has yard access.
For Abode shoppers, start with the Abode Smart Security Kit, add Mini Door/Window Sensors to doors and reachable windows, use Abode Cam 2 where video verifies a real entry risk, then compare Abode plans before relying on self-monitoring only.
