How to read burglary data without getting misled

Before digging into the San Diego numbers, one note on methodology: residential burglary data comes from two main sources, and they measure different things.

FBI UCR (Uniform Crime Reporting) aggregates reports from every police department in the country. It’s comprehensive but lags — the 2024 data won’t be finalized until mid-2025. It also under-counts because many burglaries go unreported (homeowners don’t always file when nothing valuable is taken).

NCVS (National Crime Victimization Survey) from the Bureau of Justice Statistics surveys households directly. It catches unreported incidents but has smaller sample sizes for city-level breakdowns.

For San Diego-specific analysis, the San Diego Police Department Annual Crime Report and California DOJ Open Justice portal are the primary sources. The County Sheriff covers unincorporated areas (Ramona, Alpine, Julian, and the backcountry).

Most of the “smart lock increases security by X%” stats circulating online are extrapolations or vendor-funded studies. We’ve excluded those and stuck to government crime data.

The trend to watch is whether [VERIFY: the 2020-2021 pandemic-era decline has reverted, stayed lower, or continued changing]. Most criminology researchers attribute the 2020-2021 drop to reduced opportunistic targeting while people worked from home more.

When do most San Diego burglaries happen?

This is where the data contradicts homeowner intuition.

[VERIFY: FBI UCR or NIJ data on time-of-day for residential burglary] shows that [VERIFY: roughly 60% of residential burglaries occur during daytime hours], not after dark. The reason is straightforward: daytime is when homes are most reliably empty (people at work, kids at school), and break-ins during daytime are easier to explain to curious neighbors (“delivery person,” “gas reading,” etc.).

The specific peak window per [VERIFY: NIJ research] is [VERIFY: roughly 10am to 3pm]. Evening burglaries (after 6pm) account for [VERIFY: ~30%], and overnight (midnight to 6am) is actually the smallest share at [VERIFY: ~10%].

What this means for hardware choices: motion-activated porch lights and night-focused security measures address the smallest share of risk. The highest-leverage hardware upgrade — a Grade-1 deadbolt with a reinforced strike plate — works equally well day or night because it resists the kick-in attack that’s the entry method for most forced-entry daytime burglaries.

How do burglars actually get in?

[VERIFY: FBI UCR or BJS NCVS entry-method breakdown — exact percentages]

Generalized from public data:

  1. Unforced entry ([VERIFY: ~X% of all residential burglaries]) — unlocked door or window. This is the single biggest category, and it’s the cheapest to prevent: lock your doors.
  2. Forced entry through the front or back door ([VERIFY: ~X%]) — kick-in attacks against the strike plate, or pry-bar attacks against the door frame. This is where deadbolt grade + strike-plate reinforcement matter.
  3. Window entry ([VERIFY: ~X%]) — glass break, usually on ground-floor windows away from the street. Window pins and glass-break sensors address this; higher-cost but narrower application.
  4. Garage entry ([VERIFY: ~X%]) — via the main garage door (sometimes manipulated via stolen remote code) or the unlocked pedestrian garage-to-house door.
  5. Other ([VERIFY: ~X%]) — sliding glass doors, pet doors, chimney, second-story balcony.

The practical takeaway: unforced entry is the biggest single category, which means the highest-ROI defensive action is behavioral (lock doors when you leave) rather than hardware. For the forced-entry category, reinforced strike plates and Grade-1 deadbolts are disproportionately effective.

Which San Diego neighborhoods see the most residential burglaries?

[VERIFY: SDPD crime map or California DOJ Open Justice — check which SD neighborhoods / ZIPs have highest residential burglary rates per capita]

The general pattern nationwide: higher-density neighborhoods with more renters and more commuters (which means more predictable “home empty” windows) see higher burglary rates per capita than low-density single-family neighborhoods with retired / work-from-home residents.

For San Diego specifically, a hardware audit matters more in:

  • High-turnover rental areas — tenants don’t always rekey between leases, so key control is weak
  • Neighborhoods adjacent to major freeways — opportunistic burglars scout near quick escape routes
  • Vacation-rental-heavy zones — Airbnb / VRBO rotation means the “is someone home?” signal is unreliable
  • [VERIFY: specific SDPD-identified higher-burglary neighborhoods]

Across every neighborhood type, the same four hardware interventions recur:

What hardware actually moves the risk numbers?

Based on the entry-method data above, here’s the priority order for hardware upgrades (and why each one works against the specific attack patterns that are most common):

1. Make sure doors are actually locked (free)

Unforced entry is the #1 category. The single cheapest intervention is a behavioral habit: lock the door every time you leave. Smart locks with auto-lock solve this for you — the deadbolt engages 30 to 60 seconds after the door closes, regardless of whether you remembered.

2. Reinforced strike plate with 3-inch screws ($5-10 per door)

Factory 3/4-inch screws anchor the strike plate into the door trim; they fail under a kick. Three-inch screws reach into the door framing and multiply kick-in resistance dramatically. This is the highest-security-per-dollar upgrade in homeownership — we include it on every deadbolt installation call.

3. Grade-1 or Grade-2 deadbolt ($120-$280 per door installed)

ANSI/BHMA Grade 1 deadbolts survive 10 impact strikes; Grade 3 (the builder default) fails at 2. For exterior doors, Grade 2 is the minimum we recommend; Grade 1 for high-risk zones. More at how to choose a Grade-1 deadbolt.

4. Rekey after move-in or key-control concerns ($80-$110 per typical home)

The move-in rekey is a small investment with outsized upside. Builders, contractors, previous tenants, real estate agents, and their family members could all have working keys to the home you just bought. Rekeying invalidates every one of them.

5. Window security (varies — $50-$400 per window)

For ground-floor windows that aren’t visible from the street, window pins or glass-break sensors are the targeted intervention. Not every window needs this — audit which ones are actually vulnerable.

6. Visible cameras or smart doorbells ($150-$400 per camera)

These work primarily as a deterrent, not a prevention. Per [VERIFY: Ring or similar security-industry-funded study — but these are vendor studies, replace with more neutral source if possible], visible cameras reduce the likelihood of being targeted by a substantial margin, though they don’t stop a determined attacker once the decision to break in has been made.

How does all this change if you own a rental or Airbnb?

High-turnover properties face a distinct risk pattern:

  • Key control is weak. Every guest who’s ever stayed, plus every cleaner and maintenance contractor, has potentially seen or copied a key. Rekeying between long-term tenants is a California requirement in many lease scenarios; for Airbnb, smart locks with rotating guest codes are the standard solution.
  • “Home empty” signal is public. Anyone can check the Airbnb calendar to know when the property is vacant.
  • Hardware gets abused. Guests drop keys, slam doors, and jam mechanisms. Rental-grade hardware (Grade 2 deadbolt + reinforced strike) holds up; builder-grade doesn’t.

Recommended setup for rentals: keyless deadbolt with per-guest code rotation (Yale Assure Lock 2 with Airbnb integration is the most-deployed choice), Grade-2 exterior deadbolt on every non-front door, reinforced strike plates on all four corners of the frame.

What the data doesn’t tell you — limitations of burglary statistics

A few honest caveats:

  1. Under-reporting. NCVS data suggests [VERIFY: ~X% of residential burglaries are unreported]. The actual burglary rate is higher than published police data shows.
  2. Opportunistic vs. determined. All the above applies to opportunistic burglars — the majority. A determined attacker targeting a specific property will find an entry method regardless of hardware.
  3. Neighborhood-level variance is huge. County-level averages hide real differences. The hardware audit is more useful than the county stats.
  4. Hardware is the last line. The biggest predictor of not being burglarized is having active, observant neighbors — not the grade of your deadbolt.

Methodology

This analysis draws on:

  • FBI Uniform Crime Reporting (UCR) residential burglary data, 2019-2024 releases
  • California Department of Justice Open Justice portal (openjustice.doj.ca.gov)
  • San Diego Police Department Annual Crime Report
  • San Diego County Sheriff’s Department crime statistics (for unincorporated areas)
  • National Crime Victimization Survey (NCVS), Bureau of Justice Statistics
  • ANSI/BHMA A156.36 standard for deadbolts (for hardware grade definitions)

All specific statistics are cross-referenced across at least two sources where possible. Where only one source is available, it is cited inline. Placeholder [VERIFY] tags in the draft indicate where final publication requires primary-source verification.

Frequently asked questions

Is San Diego a high-crime city for residential burglary?

[VERIFY: SD County rate vs California average vs national average — e.g., “SD County residential burglary rate is roughly X per 100,000 residents, compared to the California state average of Y and the national average of Z”]

Has the 2020-2021 pandemic-era burglary drop reverted?

[VERIFY: Most recent SDPD data — did 2022-2024 return to pre-pandemic levels, stay lower, or continue changing?]

Does installing a security system reduce my insurance?

Most homeowners insurance policies offer a 5-20% discount for monitored alarm systems, reinforced doors, and smoke/fire detection systems. Exact discount varies by carrier — check with your agent.

What should I do first if I’ve just moved in?

In this order: lock every exterior door and window; schedule a rekey of all exterior locks; inspect strike plates and upgrade to 3-inch screws; test that every deadbolt fully engages; decide whether smart locks or traditional deadbolts fit your lifestyle; add cameras if needed.

Is a Grade-1 deadbolt really necessary for most homes?

No. Grade 2 is adequate for most residential exterior doors in low-to-moderate-risk San Diego neighborhoods. Grade 1 is appropriate for higher-risk areas, rural / vacation properties, or situations where the occupant wants maximum mechanical-security hardware. For most homeowners, upgrading from Grade 3 to Grade 2 combined with a reinforced strike plate is the biggest proportional gain.
