Living in an apartment or a dorm changes the security picture. You have fewer doors and windows to worry about, but you share walls, halls, stairwells and entrances with people you may not know, and you do not control the building. Most problems in these places start in the shared spaces: a door held open, a stranger who follows a resident inside, a package room anyone can enter. This guide gives you a move-in checklist for your unit and a set of habits for the building around it.

What is different about apartments and dorms

• Shared entrances. Anyone who gets through the front door of the building is already inside the perimeter, and many people hold doors for strangers out of politeness.
• Many keys. Old tenants, maintenance staff, roommates and guests may all have had keys or fobs. You cannot always know how many exist.
• Hidden hallways. A hallway or stairwell that no one watches gives a person time to look at doors and try handles.
• Limited control. You cannot rebuild the entrance, but you can change how you use it.
• People nearby. Close neighbors can also be your best protection, since they hear and see what happens.

Your move-in checklist

On the day you move in, before the boxes are unpacked, work through this list. It takes about 30 minutes.

1. Test the door. Check that it closes, latches and locks by itself, and that the deadbolt throws a full inch. Look at the frame for cracks.
2. Ask for a rekey. Ask the manager to change the lock cylinders, and ask how many keys and fobs exist. Do it in writing.
3. Check the peephole or viewer. If it is broken or missing, ask for a repair. You should be able to see who is at the door without opening it.
4. Test every window. Check latches and look for damaged screens. Note which windows can be reached from the ground, a fire escape or a balcony.
5. Check the balcony or patio door. Make sure it locks and that the track is clean. See our guide to securing a sliding glass door.
6. Check the lighting. Walk the hallway, the stairs, the entrance and the parking area after dark. Report burned-out bulbs.
7. Test the smoke and carbon monoxide alarms, and learn two ways out of the building.
8. Photograph the condition of the unit and note any damage, so you are not blamed later.
9. Save key numbers: the manager, maintenance, building security or campus safety, and the local non-emergency line.

Securing the shared spaces

The front entrance

• Do not hold the door for strangers. It can feel rude, but you can be polite and still say, "Could you buzz the resident you are visiting?"
• Check the door behind you. Make sure it closes and latches. Report a door that does not.
• Never prop the door open, and report anyone who does.
• Do not share your fob or code with people you do not know, and report a lost one right away.

Elevators, stairs and halls

• Have your keys ready before you reach your door, so you are not standing at it searching your bag.
• Trust your instincts. If someone makes you uneasy in an elevator, you can step out, or wait for the next one.
• Look before you enter a stairwell or a laundry room, and use well-lit routes.

Packages and mail

• Use the package room or locker if the building has one, and ask how it is secured.
• Collect packages quickly. Our guide on stopping package theft covers more options.
• Protect your mail. Collect it promptly, and report a damaged mailbox.

Parking and bikes

• Park in a lit space near an entrance when you can.
• Lock your car and take valuables with you. Remove or hide anything visible.
• Lock bikes with a strong lock to a fixed rack, not to a railing a thief can lift them over.

Securing your unit

After the landlord's part, add a few inexpensive layers that you can remove when you leave. Our guide to renter security without drilling covers them in depth. The most useful for apartments and dorms:

• Door and window chimes ($13 to $18 for six). They sound when a door or window opens, which is useful when you sleep and when you want to know about an entry.
• A kick-down door stop ($10 to $14). A low-cost extra layer that adds resistance and doubles as a door holder.
• Window wedges ($10 to $14 for four). They let you keep a window cracked without a person-sized opening.
• Curtains or blinds ($13 to $25). Close them at night so no one can see in, and keep valuables out of view from the street and balcony.

Roommates, guests and keys

• Agree on rules. Decide who gets a key, whether guests can be given one, and how you handle a lost one.
• Lock the door every time, even when a roommate is home, and make sure they do too.
• Be careful with spare keys. Do not hide one outside. Give one to a trusted person instead.
• Know your guests' guests. A party can bring strangers into your space. Lock bedroom doors and put valuables away.
• Change plans when a roommate leaves. Ask for a rekey and collect keys and fobs.

Extra tips for dorms

• Lock the door every time you leave, even to use the bathroom down the hall. Many dorm thefts involve unlocked rooms.
• Secure laptops and phones. Take them with you or lock them in a drawer or a cable-locked spot.
• Know your resident assistant and campus safety number, and put them in your phone.
• Do not prop doors, and do not let strangers in after hours.
• Check the rules. Many dorms prohibit certain locks and devices, including some door alarms and wedges. Ask before you buy.
• Use campus services such as safety escorts and emergency phones.

Know your neighbors

In a building, your neighbors are the best security system you have. They hear a door forced, notice a stranger in the hall and can check on you in an emergency. Introduce yourself, exchange numbers and agree to tell each other when you will be away. Our video on neighborhood communication explains how to start these conversations and what to agree on. If your building has a group chat or a resident association, join it, and report problems to the manager in writing.

What it costs: a simple plan

Common mistakes to avoid

• Letting people follow you in. One polite habit prevents many problems.
• Leaving the door unlocked for a minute. A minute is enough.
• Not asking for a rekey. You cannot know who has a key.
• Sharing a fob or code. You lose control of who has it.
• Ignoring broken lights and locks. Report them in writing.
• Forgetting the balcony. Ground-floor and low balconies need the same attention as the front door.
