Renters have a particular problem. You live behind someone else's locks, doors and windows, you may not be allowed to drill or replace anything, and you want to get your deposit back. But you also have the same need for a safe home as anyone else. The answer is a set of removable, damage-free tools that you can take with you when you move, together with a few things that your landlord should handle. This guide covers both.

What you control, and what you do not

It helps to sort your home into two lists.

Your landlord is usually responsible for the condition of locks, doors, frames, windows, common-area lighting, entry systems and smoke and carbon monoxide alarms. Laws on this vary by place, but most require a basic level of security and working locks. It is reasonable to ask for a rekey when you move in, because you cannot know who still has a key.

You are usually responsible for your habits, your own detection and your own portable devices. You can add many things without changing the unit, and you can take them with you when you leave.

Before you buy anything, read your lease for rules on locks, drilling, adhesives and cameras. When the lease is unclear, ask in writing. A short email that asks "May I install a battery-powered motion light on the patio wall using removable adhesive?" gets you a record and avoids a dispute.

Step 1: Ask for the basics (free)

• Rekey or change the locks. Ask the landlord to rekey the entry locks when you move in. In many places this is expected between tenants. It costs little, and it ends old keys.
• Repair what is broken. Window latches, door frames, door closers, exterior lights and loose strike plates are maintenance items. Report each one in writing, and keep a copy.
• Ask about changes. If you want a deadbolt, a better strike plate or long screws, ask if you may do it, or ask the landlord to. Many agree, especially if you offer to pay or to restore the original on move-out.
• Document the condition. Photograph doors, locks and windows at move-in, so you are not blamed for existing damage.

Step 2: Removable door protection

The door is the most important opening, and several devices strengthen it without drilling.

• A kick-down door stop ($10 to $14). It mounts at the base of the door or sits on the floor and adds resistance when the door is shut. It is a modest layer, not a primary defense, and it doubles as an ordinary door holder.
• A portable security brace or bar. A brace that wedges between the door and the floor blocks a door from being pushed in. Some models are made for French or double doors and fit without screws. Make sure you can remove it in seconds from inside.
• A removable door chime or alarm. A battery-powered sensor on the door sounds when it opens.

Never use a device that you cannot remove quickly in the dark. Your front door is your fire exit.

Step 3: Sliding doors and windows

Sliding doors are often the weakest opening in an apartment, especially on a ground floor or balcony. A bar or a dowel in the track blocks the door from sliding even if the latch fails, and it needs no installation. Our sliding door guide explains the rest, including the lift-out problem.

For windows, a hook-and-loop wedge limits how far a window opens, so you can keep it cracked for fresh air without leaving a person-sized gap. It releases by hand, so it stays safe in a fire. See our guide to securing windows for the rest.

Step 4: Detection that needs no wiring

Battery-powered devices let you add detection and light without touching the building.

• Door and window chimes ($13 to $18 for six). They sound when an opening is forced or opened. They need no hub, wiring or subscription.
• A battery video doorbell. Some models hang over the door or mount with a bracket that needs no wiring. They show who is at your door and record visitors, but video history often needs a paid plan. Check your lease first, and use an adhesive or a mount that does not damage the door.
• A wireless motion light. A battery-powered spotlight mounts almost anywhere in minutes and lights a trouble spot such as a patio or a path. It is small and dim compared with a floodlight, but it is cheap and removable.

Step 5: Habits that cost nothing

• Lock every time. The door and the windows, even when you are home.
• Do not prop open doors. That includes the building entrance and the garage gate.
• Check who you let in. Verify visitors and workers before opening the door.
• Limit your keys. Know who has one. Do not hide a spare outside.
• Keep valuables out of sight from the windows and the balcony.
• Know your neighbors. A neighbor who knows you is your best alarm.

What to take when you move

Removable devices go with you, so budget them as a kit. When you move, pack the track bar, the wedges, the chimes, the door stop and the battery light. Remove adhesives carefully, fill any small holes if you did get permission to drill, and put back anything you took off. Photograph the unit at move-out as you did at move-in.

What it costs: a simple kit

Common mistakes to avoid

• Changing things without asking. You may lose part of your deposit or break your lease.
• Making repair requests by phone only. Keep a written record.
• Using a device that blocks your exit. It must come off in seconds.
• Forgetting the balcony or patio door. Ground-floor and balcony doors need protection.
• Skipping the rekey. You cannot know who has an old key.
• Relying on the building. A secure entry door does not stop a tailgater. See our apartment and dorm checklist.
