Last June, a church in East Memphis discovered that someone had crawled under their passenger van overnight and sawed off the catalytic converter. Replacing it cost $2,800. The van sat in the church parking lot for three weeks waiting on parts. The thief, if he sold the converter to a scrap buyer, probably got $150 to $250 for the job.
That math, a few hundred dollars for the criminal and thousands for the victim, is playing out across Tennessee at alarming rates. Catalytic converter theft is just one piece of the summer property crime picture, and 2022 is shaping up to be worse than last year. Warmer weather has historically meant more crime in Tennessee, and the conditions driving property offenses haven’t improved since 2021.
The Summer Pattern Is Real
Criminologists have documented the link between warmer weather and property crime for decades. The explanation is straightforward enough. Longer days mean more hours of activity. More people leave homes and businesses open or unsecured. Windows stay open. Garages stay unlocked. Cars sit in driveways with valuables visible. The target-rich environment expands in summer.
FBI Uniform Crime Report data consistently shows that property crime in the United States peaks between June and September. Tennessee follows this national pattern closely, with July and August typically producing the highest monthly totals for burglary, larceny, and motor vehicle theft.
Memphis exaggerates the pattern. Shelby County’s property crime numbers in summer 2021 ran roughly 18% higher than the winter average. Neighborhoods along the Raleigh-Frayser corridor, in Hickory Hill, and across parts of Whitehaven saw the sharpest seasonal spikes. Auto theft and auto burglary drove much of the increase, with thieves targeting vehicles parked at apartment complexes and along commercial strips where overnight foot traffic drops to zero.
Nashville’s summer crime pattern is more diffuse geographically, spread across a metro area that covers 525 square miles. The concentration points tend to cluster around commercial corridors. Murfreesboro Pike, Dickerson Pike, Gallatin Pike, and Nolensville Pike all see elevated property crime during warmer months. Antioch and Madison have produced the most consistent summer increases in recent years.
Catalytic Converter Theft: A Thousand Dollars Under Every Car
No property crime trend in Tennessee has grown faster than catalytic converter theft. The devices, which contain platinum, palladium, and rhodium worth anywhere from $100 to $300 at scrap prices, can be removed from a vehicle in under two minutes with a battery-powered reciprocating saw.
The preferred targets are Toyota Priuses and full-size pickup trucks. Priuses use converters with higher concentrations of precious metals. Trucks and SUVs sit high enough off the ground that a thief can slide underneath without a jack. Honda Elements, Honda CR-Vs, and Ford F-150s also rank high on the target list.
Replacement costs for victims range from $1,000 for an aftermarket converter on a common model to $3,000 or more for OEM parts on hybrids. Some victims have had converters stolen twice within six months. Insurance covers the replacement in most cases minus the deductible, though some insurers have started excluding catalytic converter theft from standard policies.
Memphis has been hit particularly hard. MPD reported a significant increase in catalytic converter theft reports through 2021, with the trend accelerating in the second half of the year. The thefts happen everywhere: church parking lots, hospital garages, apartment complexes, shopping center lots, and residential driveways. Overnight hours between midnight and 5 a.m. account for the majority of incidents, though daytime thefts in busy parking lots have become more common as criminals have grown bolder.
Nashville’s numbers tell a similar story. Metro Nashville Police have investigated hundreds of catalytic converter thefts over the past year, with losses concentrated in the Antioch, Hermitage, and Donelson areas. The Tennessee legislature passed a law in 2021 requiring scrap metal dealers to maintain records of catalytic converter purchases, including photo ID from sellers. Enforcement of that law has been uneven, and criminals have responded by selling to out-of-state buyers or through informal networks that don’t comply with reporting requirements.
For businesses with fleet vehicles or customer parking, catalytic converter theft is both a financial risk and a liability concern. A commercial property where a customer’s converter gets stolen may face claims that inadequate security contributed to the loss. The most effective deterrents are basic: well-lit parking areas, visible security cameras, and the presence of guards or patrol vehicles during overnight hours.
Retail Shrinkage: The Problem Nobody Wants to Quantify
Retail theft, categorized as “shrinkage” in industry terminology, costs Tennessee retailers hundreds of millions of dollars annually. The National Retail Federation’s most recent survey estimated that shrinkage costs U.S. retailers $94.5 billion per year, with external theft accounting for roughly 37% of losses.
Tennessee retailers report that organized retail crime has intensified since 2020. The pattern involves teams of thieves hitting multiple stores in a single day, filling bags with high-value items like electronics, cosmetics, clothing, and over-the-counter medications, and leaving before store employees can respond. The stolen goods end up on online marketplaces within hours.
Memphis and Nashville have both seen this pattern escalate. Dollar General, which is headquartered in Goodlettsville just north of Nashville, has cited retail theft as a significant factor in store profitability across its Tennessee locations. Walgreens, CVS, and Kroger locations in high-theft areas have responded by locking up more merchandise behind cases and reducing operating hours. Some locations have hired private security guards to stand near high-value sections, a visible deterrent that doubles as customer service in theory.
Summer compounds the retail theft problem because stores are busier, staff is stretched thinner (many retailers rely on seasonal employees with less training), and the longer operating hours create more windows of opportunity. Security companies that serve retail clients in Memphis and Nashville are staffing up for summer coverage. The demand for loss prevention officers, typically unarmed guards trained in shoplifting detection and evidence documentation, is strong.
Vacant Properties: The Invisible Target
Every Tennessee city has them. Vacant commercial buildings, foreclosed homes, and abandoned lots that attract vandalism, squatters, and illegal dumping during summer months. Memphis has the largest inventory of vacant properties of any Tennessee city, with thousands of parcels sitting empty across Shelby County.
Vacant property crime is often unreported or underreported because there’s no immediate victim present to call police. The damage accumulates: broken windows, stripped copper wiring, graffiti, illegal waste dumping, and occasionally arson. When a property owner eventually discovers the damage, the cost of remediation can exceed the property’s value.
Some property owners contract with security firms for periodic inspections of vacant holdings. Mobile patrol services that check properties two or three times per week, verify doors and windows are secure, and report any signs of intrusion offer a cost-effective solution. The patrol schedule varies enough to be unpredictable, which matters because regularity invites exploitation. A trespasser who knows the security guard comes at 10 p.m. every Tuesday learns to come at 10 p.m. every Wednesday instead.
Memphis code enforcement has stepped up efforts to hold owners of vacant properties accountable for conditions, including requiring adequate security measures like fencing and boarding. Property owners who ignore code violations face fines and potential liens. For out-of-state owners with vacant Memphis properties, hiring a local security firm for weekly inspections is often cheaper than accumulating fines.
Nashville’s Security Budget Season
Nashville’s fiscal year starts July 1, which means businesses across Davidson County are finalizing their security budgets right now. Property managers, retail operators, and commercial landlords are deciding how much to spend on guards, cameras, and access control for the coming year.
The conversations have changed. Two years ago, security was a line item that many Nashville businesses trimmed first when cutting costs. Today, it’s being treated more like insurance: nobody wants to pay for it until they need it, and by then it’s too late.
Commercial property managers in Nashville’s SoBro, Midtown, and West End corridors report that tenants are asking about security provisions before signing leases. A building’s security setup, including guard presence, camera coverage, and lighting, has become a competitive factor in attracting and retaining tenants. Buildings with visible security command higher rents and lower vacancy rates. Those without it are starting to feel the difference.
Knoxville’s Downtown Moment
Knoxville doesn’t generate the same crime headlines as Memphis or Nashville, and that’s partly why its security needs get overlooked in statewide conversations. The city’s downtown revitalization, centered on Market Square, Gay Street, and the Old City, has brought new restaurants, breweries, hotels, and retail to areas that were half-empty a decade ago.
With revitalization comes security questions. Foot traffic on Gay Street on a Friday night now rivals some Nashville corridors. The increased activity is overwhelmingly positive for the city’s economy. It also creates density that attracts property crime, aggressive panhandling, and vehicle break-ins in parking garages along Clinch Avenue and Church Avenue.
Knoxville’s downtown businesses have formed a security cooperative of sorts, pooling resources to fund additional patrols during peak hours. The model works for dense commercial districts where businesses share common areas and parking structures. Several Knoxville security firms have expanded their downtown patrol coverage in anticipation of a busy summer tourist season.
Preparation Beats Reaction
The businesses that get through summer with minimal property crime losses aren’t lucky. They’re prepared. Preparation means auditing your property’s physical security before Memorial Day. Check lighting and replace burned-out fixtures. Test camera systems and verify that recording equipment is functioning. Trim landscaping that creates blind spots. Verify that access control systems at gates and doors are working correctly.
For businesses with security guard contracts, this is the time to review your coverage schedule. If your guard leaves at midnight and your parking lot sits empty from midnight to 6 a.m., you’ve created a window that experienced criminals know how to exploit. Extending coverage by even two or three hours can close the most vulnerable overnight period.
The businesses that wait until after a break-in or theft to invest in security always pay more. They pay for the loss itself, for the emergency security contract at premium rates, for the insurance deductible, and for the reputation damage when customers or tenants learn about the incident.
Tennessee’s summer property crime season starts in a few weeks. The criminals are already planning. The question for business owners isn’t whether crime will happen. It’s whether anyone will be watching when it does.
