Crime Prevention Tips for Homeowners

The Baltimore County Police Department reminds residents to protect their property and valuables with these commonsense measures.

Beware of Deception Burglaries and Home Improvement Scams

Elderly Especially Warned to be Alert

Citizens are alerted to certain crime trends that have occurred throughout the county in recent years. Deception burglaries and home improvement scams occur throughout the year, but are known to increase when the weather gets warmer. Typically these are criminals who are on the move. They begin working in the southern states and head north during the spring and summer months.

The elderly are the most likely targets since they tend to be trusting and very concerned about their property and their neighborhood. Adult relatives of senior citizens should remind them of this possible crime.

Deception Burglaries

Be mindful of certain ruses:

  • Suspects generally work in pairs and approach homeowners at their residence with the intent of gaining entry under a seemingly benevolent role like posing as a legitimate worker from a local gas company, water department, cable company, or as a tree trimmer, paver, county inspector, or government official. One suspect will distract the homeowner while a second suspect will quietly enter the home and search for valuables and cash.
  • A suspect may also pose as a family friend of a relative or friend of a neighbor. He or she will knock on the door and ask for a pen and paper to leave the victim's neighbor a note. The suspect may appear to have difficulty writing the note, and will ask to come inside the house. Once inside the victim's house, the suspect will ask the victim to help write the note. While that criminal distracts the victim, others enter the residence to remove money and valuables.

A variety of vehicles have been associated with these subjects including pickup trucks, vans, and sport utility vehicles. Often, the victim doesn't even know he or she has been victimized for hours or days later when they might go looking for a piece of jewelry or precious heirloom.

Be alert to anyone in your neighborhood asking to gain entry into your home. Always ask to see identification and let them know you are going to call and get authorization from their company before allowing them access. If they are legitimate, they won't mind the wait.

Investigators believe many deception burglaries don't get reported because the victim is too embarrassed or fears retribution. Neglecting to call may allow a criminal to go free and victimize someone else.

Remember, do not intervene, but call 911 immediately with a description of the suspect and vehicle used in the suspicious activity.

Home Improvement Scams

Scam artists drive through neighborhoods looking for people in their yards. Home improvement scams often involve someone posing as a repair person who offers a bargain price on a home repair. The Baltimore County Police Department says to beware when a repair person knocks on your door. Look for these telltale signs:

  • The repair person drives an unmarked truck or van with an out-of-state license.
  • Only rarely will legitimate home improvement companies solicit door-to-door. They usually distribute fliers or make phone calls since it's more cost effective for them.
  • The worker has no business identification, local address or telephone number. Request identification so that you can call the company for verification.
  • You are offered a “special price” if you sign that day. Contractors don’t pressure customers to sign a contract or job order immediately.
  • Beware of excuses such as "We just finished a job around the corner and had extra materials that we could offer you at a discounted price." Professional companies do not operate in that manner.
  • The worker asks for upfront costs or fees, or accepts only cash. Reputable contractors do not ask for all the money up front. A customer pays one third of the bill first, then another third midway through the job, and the rest when the work is completed.
  • Never pay in cash. Using a check keeps a record of the transaction and often provides identification of the person cashing the check.
  • No written estimates or contracts are offered. If you have no contract, you have no recourse if the job is faulty or is never completed.
  • The worker has no references. Ask for references and check around the neighborhood to see if anyone has contracted with this person to do work on their home.

These scam artists also like to intimidate their prey. After a job is finished, usually with inferior materials and shoddy work, the customer is informed that they owe more money. When the customer objects, he or she is told that the materials used were stolen and the police will be brought in if the higher price isn’t paid.

Beyond the intimidation, the materials and workmanship used in this type of scam are usually of poor quality. 

Compare estimates with other licensed contractors when you decide to have work done on your home. Don’t give your hard-earned money to some “fly by night” contractor.

If you suspect that the person at your door is a scam artist, contact the Baltimore County Police Department at 911. You could be helping other potential victims from being scammed. 

Lock All Doors and Windows

The Baltimore County Police Department reports that burglaries in the County are oftentimes committed through unlocked doors or windows. Stop these thefts. The best deterrent to keep thieves from stealing your property is a lock and key.

Don't assume you are safe just because you are at home. It's nice to open the windows and let the fresh air into our homes, but remember these tips to avoid a burglary.

  • Lock windows on the first floor or ground floor even if there is an enclosed or screened-in porch. It takes so little time and effort to cut through screen mesh and gain access to a home or apartment.
  • Secure basement windows and doors. It can be easy to forget about this area of the house when we're running in and out doing chores.
  • Place a security bar, often referred to as "Charlie bars," between the patio sliding door and doorjamb. Don't assume that the latch on the door is secure enough to ward off a thief.

Working Outside? Stop a Burglar

Often, burglars watch and wait to see where you are and what you are doing. Lock up while you spruce up!

  • Out working in the yard or garden? Make sure all doors and windows—sheds, garages, patio and house—are closed and locked. This is especially true if you are in the front yard and the storage area is in the back, or vice versa. Carry a key with you to lock and unlock these doors.
  • Finished with that yard work? Remember to clean up and lock up behind you. An open door is an invitation to a thief. When you put your tools away, don't forget to lock the doors.

Dial 911 if you see anyone suspicious lurking around your neighborhood. An officer can cruise through the area to check things out. You can even remain anonymous.

Burglars Shun Good Locks and Lights

A burglar placed under arrest told Baltimore County Police that there are two types of specialty locks that he and other thieves avoid: hidden shackle locks and disc brake locks.

Hidden Shackle Locks

These locks are often used on tractor trailer doors, but homeowners and businesses use them on storage sheds and other structures easily accessed from the outside.

The locks are effective because there is no real practical way to cut the lock with bolt cutters. Also, prying them out of the door is time consuming and noisy. The core of the lock is set into the lock. They can be purchased at home improvement and hardware stores for a minimal investment of about $40.

Disc Brake Lock

The other, yet effective, locks the thief referred to are used to secure ATVs and dirt bikes.

The lock attaches to a wheel on the bike or All-Terrain Vehicle (ATV). For those who want to spend extra on security, there is a more sophisticated lock that has a built-in motion detector alarm. The locks can be purchased online, at motorcycle shops, and at some home improvement stores. Some stores will even special order a lock. The locks range in price from $40 to $90.


The thief also said a simple light shining in a shed or other structure keeps people like himself away. Burglars like to work in the dark.

No one can prevent crime, but specialized locks and good lighting are deterrents for would-be thieves.

Neighborhood Awareness: The Key To Crime Prevention

A good neighbor can be one of the best crime prevention tools. This is particularly true when various criminals and con artists use the warm weather to take advantage of residents, particularly the elderly. Watchful eyes in the neighborhood can spot criminals and alert police and the community to their presence.

Keep a check on your neighbors. If, for example, you see an elderly resident in conversation with a stranger, politely inquire about what is going on. If residents see strangers sizing up their neighbor's home, that could also be a sign something is wrong.

A call to 911 will get an officer to the scene to check things out. Involvement such as this builds stronger bonds between neighbors, and helps maintain safe neighborhoods.

Cars Unlocked, Windows Open and Convertible Tops Down

An Open Invitation to a Thief

Warm, sunny days invite drivers to roll down the windows, and for some, drive with the top down on their cars. Unfortunately, that same wonderful weather invites thieves too.

Drivers and passengers are reminded to be cautious when leaving a vehicle open. While it may be inconvenient to put the windows and top up every time the vehicle is parked, it is even more troublesome to find it ransacked.

Leaving your car doors unlocked is another open invitation to thieves.

Cell phones and other items can be easily stolen from the vehicle when the doors are left unlocked or the top is down. Important papers such as insurance and vehicle registration information often found in the glove compartment are also at risk of being stolen. This paperwork could help a thief gain personal data that might lead to identity theft.

Last but not least, the vehicle can be stolen.

Never Tell Strangers About Your Home Security

Don't give information to anyone asking about your home security. If someone claiming to be a sales person comes to your door or calls your home asking about your home security—politely turn them away. The individual may be a legitimate sales person from a home security firm hoping to make a sale, or that caller could be a would-be burglar hoping to find unprotected houses.

Don't tell a stranger whether or not you have a security system. If you do have a system, don't reveal anything about it. Simply tell the caller you don't discuss information like that with strangers. And don't be swayed if the caller mentions the name of a neighbor who may have purchased a system. Just knowing a neighbor's name doesn't make a caller legitimate.

If you don't have a home security system but would like to get one, shop around. Carefully look for established, local firms.

Keep Your Garage Door Opener Out of Sight

A smart thief can use the garage door opener to get into your house so keep it out of sight from strangers. 

Thieves can break into cars all too easily and if the garage door opener is out in the open, on the front seat or the dash, they can use it to open the garage. That allows them to rifle the garage, taking power tools, bikes and other valuables stored inside. If there is a door into the house from the attached garage, thieves might then be able to get into your home and steal more valuables.

This can be prevented if you simply keep the garage door opener out of sight—even out of your car. Carry it in a briefcase or a purse, away from prying eyes and hands.

Also make sure that the door to the house from the garage has a sturdy lock. A high-quality deadbolt is the best kind. It will slow a thief down and maybe even discourage that thief completely.

Got a Bike, Lawn Mower or Other Equipment?

Photograph It, Engrave It, Lock It or Lose It

Bike riding is a wonderful recreation. But if your bike is stolen, hiking will be more your speed. Here are a few suggestions for keeping your bike and other valuables safe and secure.

  • Record the make, model and serial numbers of your bike, mower and other equipment. Take pictures of you with your equipment and keep the information in a safe place. If your item is stolen, the photo will make it easier for police to find it. If the stolen item is found, the photo with you in it will make it easier to prove you actually own it.
  • Engrave your valuables. Engraving is simple and fast. You can even borrow an engraving tool from your local Baltimore County Police precinct. Officers say using the ID numbers from a driver's license or Maryland ID card is the best way to mark your personal belongings. Never use a social security number as an ID number! If the item is stolen and later recovered by police, the engraved number will allow investigators to get that property back to you. The engraved number might even deter a thief from taking your property in the first place, since the ID number makes it harder for criminals to dispose of valuables through underworld channels.
  • When storing your bike in a shed or garage, secure it to another large piece of equipment, like a lawn mower or workbench. Attaching it to a piece of heavy equipment makes it more difficult to just walk or ride away from the area.

For more information on how to safeguard your valuables contact your precinct's Community Outreach Team.

Put Your Mail in Your Mailbox for Pick Up

There are some residents, especially the elderly, who like the convenience of putting their outgoing mail on top of their home mailbox or inside of it with the red flag up for the letter carrier to pick up as part of the daily rounds. This practice can be even more convenient for would-be thieves and con artists.

Unscrupulous individuals can easily walk up to your door, quickly grab your mail and walk off with it. In those envelopes might be the names and addresses of family members, the names of banks and credit card companies with whom you do business, and, of course, your account numbers.

This sort of information can be invaluable for criminals attempting to pull off various scams and frauds. Don't help them out—take your mail to the post office or corner mailbox. Or wait for the letter carrier to arrive and give it to him or her in person. That may seem like an inconvenience, but becoming the victim of a fraud is a much bigger headache.

Fraud Often Follows Disasters

If a natural disaster forces you to leave your home or business, have you taken the necessary precautions to protect your identity? Gather identification and important documents before disaster strikes.

If you must leave your home due to weather conditions, you will need certain documents to identify yourself and your family. Police suggest you do the following:

  • Make copies of birth certificates, driver’s licenses, social security cards, death certificates, bank account numbers, insurance papers and any other bits of information for each member of your family.
  • Take those papers and store them in a watertight locked box, or large waterproof plastic bag.
  • Don’t put the papers in your vehicle until you are in the car and ready to go. Thieves are opportunists and will break into your car to gain access to your valuable papers.

Business owners are advised to protect vital information by scanning and encrypting paperwork as well as other sensitive files to protect customers, employees, and vendors. If that isn’t feasible, detach the Central Processing Unit (CPU) and take it with you.

Don’t let thieves steal your hard-earned name and reputation. Keep important papers and documents with you.

A Vacant House is a Temptation to a Thief

Are you going out of town? Complete a Vacant House Form and deliver it or email it to your precinct. Officers will then check on your location for any unusual activity while you are away. If something suspicious does happen at your home, law enforcement will be able to quickly reach you or a local emergency contact from the information provided on the form.

Additionally, don't leave your home looking dark and unoccupied. Use a timer to turn on lights or the television to make it appear that someone is home. If you know you will be away for a few days, ask a trusted neighbor, friend or relative to collect your mail and newspapers. A pile of unclaimed mail is a red flag for would-be thieves that nobody is home. If there is no one available to collect your mail, you can also speak with the post office about stopping mail delivery for the duration of your trip.

Don’t broadcast that you will be away. Social media sites are great ways to keep in touch with friends and family, but they’re also great tools for burglars to use in choosing targets. Don’t post photos or statements that would let someone know that you’re away from home. If you want to keep in touch with a friend or family member while you’re away, do so using a more private form of communication such as an email or text message.

Residential Security Surveys

Did you know that you can request a community outreach officer to come out to your home to provide additional security measures? Simply call the Outreach Unit of your local precinct and an officer will make an appointment to meet with you and assess your home security. The officer will provide additional security measures to help you stay safe in your home. 

This service is free to County residents.
