Home Security Basics for Renters and Owners

A neighbour once mentioned that she had lived in her flat for three years before realising the sliding door latch had been broken the entire time. Nothing bad happened, but it was a reminder that most security gaps are not dramatic; they are small oversights that sit unnoticed until someone finally checks.

For Renters

Renters often assume they cannot improve security because permanent changes to the property are off the table, but a surprising amount can be done without touching a single wall.

• Request a lock change or rekey when moving in, since you have no way of knowing how many old keys are still in circulation
• Add a portable door brace or additional chain lock that can be removed without leaving marks when you move out
• Use battery-powered window and door sensors instead of hardwired alarm systems, which travel with you to the next place
• Check that sliding doors and windows have working secondary locks, not just the main latch
• Keep a record of anything valuable with photos, stored somewhere other than on the device most likely to be taken

For Owners

Owning a property removes the restrictions renters face, which means security upgrades can go further and last longer.

• Install deadbolts on all exterior doors, including those leading from a garage into the main house
• Reinforce door frames with longer screws at the strike plate, since the frame often fails before the lock itself does
• Add motion-sensor lighting around entry points, which deters opportunistic attempts more effectively than most people expect
• Consider a monitored alarm system if the property is often empty for long stretches
• Trim back hedges and shrubs near windows and doors that could otherwise provide cover

Habits That Matter More Than Equipment

No lock or camera compensates for habits that undercut it. A spare key left under a mat or planter is one of the first places anyone would check. Leaving a garage door cracked open "just for a minute" adds up over a year into a meaningful amount of exposure. Posting travel plans publicly on social media before a trip, rather than after, tells more people than intended that a home will be empty.

A Simple Walkthrough to Try This Week

Walk around the outside of your home at night, from the perspective of someone trying to get in unnoticed. Note which doors and windows are hardest to see from the street or from neighbours, since those are the ones worth prioritising. Check that every exterior light actually works, and that no window locks have been left unused out of habit rather than necessity.

Talking to Neighbours

Security is rarely a solo effort, even for people who live alone. Neighbours who know each other’s routines tend to notice faster when something looks off, whether that is an unfamiliar car parked for too long or a parcel left on a doorstep well past when it should have been collected. A short conversation about watching out for each other during holidays or late shifts costs nothing and often does more than an extra lock.

Security rarely comes down to one big investment. It is closer to a series of small, consistent checks that together make a home a less convenient target than the one next door.
