Why Burglars Avoid Some Homes (And Walk Right Past Yours): A 12-Factor Tour

What convicted burglars say about how they pick targets, what stops them from picking yours, and the 12 factors — drawn from criminology research and offender interviews — that actually move the needle.

By Randy Plaice ·

Most “what burglars look for” articles online repeat the same six bullet points, sourced from each other in a loop, no one ever pointing back at the original research. The actual research is more interesting and more useful.

Two strands of work matter most. The first is the Bureau of Justice Statistics’ National Crime Victimization Survey, which has tracked household burglary characteristics for decades and is the closest thing to a representative national dataset. The second is a body of interview studies with convicted burglars, including the much-cited 2009 KGW Portland (Oregon) survey of 86 incarcerated burglars and academic work like Wright and Decker’s Burglars on the Job and the more recent UNC Charlotte / Department of Justice-funded survey by Joseph Kuhns and colleagues. Their findings overlap on most points, which gives the patterns more weight.

Twelve factors come up repeatedly. They’re listed in roughly the order they’re encountered as someone walks past your house — curb to back yard, then inside.

The 12 Factors That Actually Matter

1. Visible Cars in the Driveway

A car in the driveway is the single most consistent “house is occupied” signal. Almost every interview study reports that a car in the driveway is a meaningful deterrent — not because burglars assume someone is necessarily home (they could be working from home, sleeping, in the back yard), but because the uncertainty cost is too high.

What this means for you: even if your household has two drivers and two cars that both leave during the day, an old or rarely-used vehicle parked in the driveway has real deterrent value. Vacation prep advice to “ask a neighbor to park in your driveway” comes from this finding directly.

2. The House Looks Watched

Cameras matter, but the broader signal — “someone is paying attention to this property” — matters more. Address numbers cleanly visible. A swept walk. A trimmed hedge. Lights that come on at dusk. None of these is a security feature in the narrow sense, but together they communicate “this household notices things.”

The reverse — uncollected mail, faded signs, peeling paint, dead landscaping, a dark porch — communicates the opposite. Crime-against-place criminology calls this “signs of disorder,” and it’s been studied since the 1980s under various names (Wilson and Kelling’s “Broken Windows” framing is the popular version). Disorder signals don’t cause burglary, but they correlate with target selection.

3. The Front Door Is Visible from the Street

Burglars consistently report avoiding houses where they couldn’t approach the front door without being seen by passing cars or neighbors. Sightlines from the street to the door are a deterrent. Tall hedges, recessed entries, and overgrown shrubs that screen the front door are what they prefer.

This is why the tactical foliage approach is to keep sightlines to the front door clean and block sightlines to side windows, not the other way around.

4. Visible Security Signage and Camera Indicators

Security-system yard signs, camera indicators, and decals are reported as effective deterrents in nearly every interview study, with one important caveat: experienced offenders often report being able to tell real systems from fake ones (fake camera dummies, signs without the corresponding system). The deterrent effect is strongest when the signage is real and corresponds to actual hardware on the house.

A real Ring doorbell with the “Ring” branding visible is a stronger signal than an off-brand doorbell of equivalent capability, because the brand is the deterrent.

5. Audible or Visible Alarms

Alarms are consistently cited as a top deterrent. Notably, the 2013 UNC Charlotte study (funded by Alarm Industry Research and Educational Foundation, so factor in the funding source) reported that the majority of burglars they surveyed would consider alarms a reason to bypass a target, and that an audible alarm during entry would cause most to flee.

The funding-source caveat matters but the underlying finding is consistent across other studies as well: alarms work, primarily by accelerating the burglar’s exit timeline.

6. Dogs

Dogs come up in every interview study, often as the single most-cited deterrent. The interesting wrinkle: it’s not the breed or size that matters most — it’s the audibility. A small barking dog inside the house is a stronger deterrent than a large quiet one in the back yard, because the barking signals occupancy and risk to neighbors hearing the disturbance.

A “Beware of Dog” sign without a dog has weaker effect (offenders frequently report being skeptical of signage). The combination of sign and audible dog is the highest-deterrent configuration.

7. Active Neighbors

Burglars consistently report avoiding neighborhoods where neighbors appear to know each other and watch each other’s houses. Neighborhood Watch signs are a moderate deterrent; actively-engaged neighbors visible in their yards are a much stronger one. This is one of the genuinely free deterrents — knowing your neighbors and being known to them is the cheapest security upgrade available.

8. Lighting

Exterior lighting at every entry point is consistently cited as a deterrent, particularly motion-activated lighting at the front door, side approaches, and garage. The KGW survey and academic work agree: well-lit approaches are avoided in favor of dark ones.

The mechanism is partly about visibility (burglar can be seen) and partly about uncertainty (lights coming on signal that someone may have noticed). Solar-powered motion lights at $25 each at every entry point is one of the highest-leverage moves available.

9. Sound from Inside the House

Radios on a timer, TVs left running, lights on a timer — anything that suggests internal activity is a deterrent. The signal value is highest at unusual times: a TV running at 3 AM is a stronger occupancy signal than at 9 PM, when half the houses on the block have a TV running.

10. Window Locks and Visible Reinforcement

Many burglars report quickly testing windows during the approach. A window that lifts smoothly when pushed up from outside fails the test silently. A window that resists — because of a sash pin, a wedge, a secondary lock — visibly fails it.

This is why the secondary-lock layer matters more than the glass itself for opportunistic threats. The glass is going to feel attractive only if the rest of the window has already passed the “easy” test.

11. Hidden Approach Paths

The blind side of the house — the side the street can’t see, the neighbor can’t see, where someone could spend ten minutes working on a window without observation — is the side most likely to be entered.

Most homes have one. The fix isn’t to fence it (fences invite climbing); it’s to plant something painful along it. Hawthorn, holly, pyracantha along the fence line work where a fence alone doesn’t.

12. Time of Entry

Burglary is a daytime crime more often than the popular imagination suggests. BJS data has consistently shown that completed residential burglaries are more likely to occur during daytime hours (when houses are empty) than at night (when occupancy is more common). The peak hours in many studies are roughly 10 AM – 3 PM on weekdays.

What this means for the average homeowner: the security setup that protects you during overnight sleep hours is not the same as the one that protects you during the workday. Cameras and alarms with phone notifications, automated lighting that simulates presence, and the visible-car-in-driveway move all matter most during daytime hours when the house is statistically most likely to be empty.

What Doesn’t Show Up in the Research

A few things that affiliate marketers love but the research doesn’t strongly support:

  • “Smart” features as deterrents. A smart bulb is no more deterrent than a non-smart bulb on a $5 timer, in terms of what offenders perceive. The smart features matter for your convenience, not for their perception.
  • High-end alarm panels vs. basic ones. Once an alarm is present, the brand and feature set don’t strongly differentiate deterrent value in offender interviews. The alarm being present is what matters.
  • Branded security stickers without a real system behind them. Easily detected by offenders with any experience.
  • Visible weapons or weapon decals. These show up in some popular advice but don’t appear as deterrents in the research; in fact, they may signal “something worth stealing inside.”

How This Translates to a Plan

If you stack the 12 factors above, the picture of “the house burglars walk past” comes into focus:

  1. A car in the driveway, even if it’s an old one
  2. A clean, well-maintained appearance from the street
  3. Clear sightlines to the front door, screened sightlines to side and back windows
  4. Real (not fake) security cameras and signage
  5. A real alarm system (visible armed indicator)
  6. A dog or audible-dog signal
  7. Engaged neighbors
  8. Motion lights at every entry
  9. Smart-bulb or smart-plug presence simulation
  10. Functioning window locks plus secondary locks
  11. Defensive planting on blind approaches
  12. Daytime as well as nighttime coverage

The house with all twelve isn’t impregnable. It’s just not the easiest house on the block, and that’s the criterion most offenders are using.

A Note on Source Reliability

Two caveats worth being honest about:

First, offender interviews are self-reported. Convicted burglars are not necessarily representative of all burglars (the ones who got caught are by definition selected for some characteristic — likely lower skill or more frequent offending). Their reasoning is also retrospective, which means it’s reconstructed and possibly rationalized.

Second, research on burglar decision-making is heterogeneous. Different studies report somewhat different rankings of factors. The 12 factors above are the ones that come up consistently across multiple studies, which is the best signal we have, but the precise weight of each is uncertain.

What seems robust: layered, visible, multi-modal deterrents work better than any single piece of hardware, and the total signal of “this house is paying attention” matters more than any individual feature within it.

This is also why the audit walk is the highest-value 30 minutes you can spend on home security. The gear is downstream. The walk is what tells you which factors your house is currently signaling — and which ones it’s not.
