Renter’s Security Checklist: What to Check Before Moving Into a New Apartment

Practical tips for evaluating apartment security before you move in—because protection starts before the lease is signed.

Finding the right apartment is about more than just square footage or natural light—it’s also about how secure you’ll feel once you move in. For many renters, security concerns don’t surface until after they’ve signed the lease or started unpacking. But the best time to assess your new home’s safety is actually before you commit to it.

From building access and neighborhood crime rates to the strength of locks and the flexibility to install your own devices, there are dozens of small details that can have a big impact on your peace of mind. And unlike homeowners, renters often have limited control over structural security features—making it even more important to know what to look for ahead of time.

This guide walks you through a practical, renter-friendly checklist to help you evaluate your next apartment before move-in day. It covers what to inspect, what to ask about, and how to plan for simple security upgrades you can implement on your own—no drilling, no long-term contracts, and no surprises after signing.

Start with the Surroundings: Neighborhood & Building Safety

Before stepping inside the apartment itself, take a broader look at the environment it’s part of. The safety of your building often starts at the block level—and many important clues are visible before you even walk through the front door.

Check Neighborhood Crime Trends

Do a quick scan of recent activity in the area using publicly available crime maps, neighborhood watch websites, or apps like Nextdoor and Citizen. Look for patterns like frequent break-ins, theft, or vandalism, especially near apartment complexes or retail zones.

While no neighborhood is crime-proof, understanding the local context helps you decide what level of personal security may be necessary—and can guide your setup later on.

Evaluate Entry Access to the Building

Observe how the building handles access and visitor control:

• Is there a secure front entrance, or can anyone walk in?
• Are buzz-in or keypad systems functioning and modern?
• Does the lobby or entrance have a visible camera or intercom?

These features add passive protection and signal how seriously management takes resident safety.

Look at Exterior Lighting and Sight Lines

Poor lighting in parking lots, walkways, and stairwells can create blind spots for residents—and opportunities for intruders. During your visit, check:

• Are building entrances and pathways well-lit?
• Is lighting motion-activated or always on?
• Are any cameras positioned to cover those areas?

If visiting during the day, consider driving by at night to assess visibility and foot traffic 

Evaluate the Apartment’s Physical Security

Once you’ve assessed the broader environment, it’s time to take a closer look at the unit itself. While renters may not be able to modify doors or wiring, there are still key security indicators that can help you determine how safe the apartment is—or how much effort it might take to make it feel secure.

Inspect Doors and Locks

Start with the front door. Ideally, it should be made of solid wood or reinforced metal—not hollow-core. A secure apartment door should include:

• A functioning deadbolt (preferably one-inch throw)
• A sturdy strike plate with long screws anchored into the doorframe
• A peephole or wide-angle viewer, especially if there's no door camera

Ask the leasing agent if the locks are changed between tenants. This isn’t always standard practice, but it should be. If they hesitate, clarify whether you’re allowed to request a rekeying or upgrade.

For units with a balcony or separate back door, check that those entrances have equivalent lock quality. Sliding doors should include a security bar or pin lock to prevent lifting or forced entry.

Check Windows—Especially at Ground Level

Windows are often overlooked, but they can be vulnerable access points. Open and close them to make sure latches are functional and that they lock securely. If you’re on a ground floor or near a fire escape, note whether window bars or secondary locks are installed.

In older buildings, screens may be flimsy or torn—offering little resistance and even less peace of mind. In those cases, ask about the policy on temporary reinforcements, like window alarms or childproof locks.

Assess Shared Walls and Sound Travel

While not a security feature in the traditional sense, thin walls and poor insulation can affect your privacy. Noise transfer can mean that conversations—or security alerts—are easily overheard, which might change how and where you install indoor devices or cameras. It's something worth considering, especially in densely packed multi-unit buildings.

Don’t Forget Maintenance Practices

Ask whether there’s a record of recent repairs or safety upgrades—especially if you spot signs of wear near locks, hinges, or frames. If you see rusted bolts, splintered doorjambs, or signs of forced entry, don’t hesitate to bring it up.

A well-maintained unit signals proactive management. A neglected one might leave you more exposed—and on your own to make up for the gaps.

Ask the Right Questions Before Signing

Even a secure-looking apartment can have hidden vulnerabilities. That’s why asking the right questions—before you sign a lease—is just as important as evaluating physical features. Landlords and property managers may not disclose every detail unless prompted, so it’s up to you to get the information that affects your safety.

Who Has Access to the Unit?

Confirm who will have keys or entry credentials after you move in. Typical access includes:

• Property managers and leasing agents
• Maintenance personnel
• Cleaning crews (if included in rent or shared spaces)

Ask how access is controlled, whether there’s a key log or electronic entry system, and what notice is required before someone enters your unit. Ideally, you should receive advance notice for any non-emergency access—and be able to change locks or codes if needed.

Are You Allowed to Install Additional Security?

Some landlords have strict policies about drilling into walls, mounting devices, or altering entry hardware. Others are more flexible, especially with non-invasive options.

Be specific when asking:

• Can I use peel-and-stick window or door sensors?
• Is it okay to install a smart doorbell or indoor camera?
• Are wireless, app-based alarm systems permitted?

Getting approval in writing protects both your lease terms and your ability to take meaningful safety steps.

What Security Features Are Already Provided?

Some apartments come with basic security systems—or building-wide measures like gated access, lobby attendants, or intercoms. Find out:

• Is there an alarm system in the unit? If so, is it active and monitored?
• Are there cameras in common areas or parking garages?
• Are entry doors and locks up to code?

Even if existing systems are minimal, knowing what’s already in place can help you plan what you’ll need to add after move-in.

Connectivity & Compatibility: Planning for Smart Security Devices

For renters who plan to install their own alarm systems, sensors, or cameras, connectivity is just as important as hardware. Before move-in, take a few moments to assess how your new apartment will support the smart security tools you may want to use.

Test Wi-Fi Access and Cell Signal Strength

If possible, bring your phone or a mobile hotspot during your walkthrough and test signal quality in key areas—like entryways, hallways, and near windows. Dead zones can interfere with:

• Smart camera streaming
• Sensor or hub connectivity
• App-based alerts and real-time monitoring

Buildings with thick walls, metal construction, or basement-level units may require a Wi-Fi extender or mesh router system. Knowing that upfront will help you avoid frustration later.

Check for Adequate Outlet Access

Most DIY security systems use a mix of battery-powered and plug-in devices. Take note of:

• Outlet locations near windows and doors (ideal for indoor cameras or hubs)
• Whether any outlets are already in use or obstructed
• Availability of surge protection if you're plugging in sensitive equipment

You don’t need a fully rewired smart apartment, but a few well-placed outlets make setup faster and safer.

Think Ahead About Sensor and Camera Placement

Use your walkthrough to visualize where you might place sensors, motion detectors, or cameras:

• Can sensors fit above doors and windows without interfering with curtains or blinds?
• Are there clear corners with good sight lines for indoor cameras?
• Will devices be visible to deter unwanted entry—or should they be discreet?

Bringing a tape measure or even just snapping reference photos can be helpful for mapping your layout later.

Smart Device Compatibility

If you use smart home assistants like Alexa or Google Assistant, or plan to build automations (e.g., lights on when motion is detected), check whether the apartment’s layout and internet setup will support those integrations.

Look for systems that allow:

• Mobile app control
• Voice assistant compatibility
• Custom rules or schedules (especially useful for shared units or irregular routines)

If you use voice assistants, learn how ADT works with smart home platforms like Alexa and Google Assistant.

Planning ahead ensures that when you move in, your security system can be deployed quickly and perform reliably—without running into avoidable setup issues.

Pre-Move Security Checklist: Your Apartment Walkthrough

Before you sign your lease—or at the very latest, before move-in day—take time to walk through the unit with a security-first lens. This isn’t just about finding flaws; it’s about identifying your baseline and knowing exactly where you might want to strengthen protection once you're settled in.

Use this checklist during your showing or final walkthrough to spot red flags and note where simple upgrades could make a real difference.

First Week Setup Tips for Renters

Once you’ve moved in, your first few days are the perfect time to put your personal security measures into place. You don’t need to overhaul the entire unit—but taking a few simple steps early on can give you lasting peace of mind, especially while you’re still settling into a new space and routine.

Here’s how to make that first week count.

1. Secure the Entry Points

Before unpacking too much, double-check that all entry points lock securely—especially if anything felt off during your walkthrough. If you haven’t already:

• Request a lock change or rekeying if it hasn’t been confirmed.
• Install a door stopper or additional security bar for sliding doors or secondary entries.
• Test any pre-installed alarms, if applicable, and make sure they’re activated.

Even renters who aren’t using a full alarm system can benefit from low-profile door and window sensors, which are easy to install and provide basic alerts.

2. Install a Basic DIY Security System

If you plan to use a renter-friendly DIY system (like ADT DIY), now’s the time to:

• Mount peel-and-stick entry sensors on key doors and windows.
• Position indoor cameras near the front door or shared spaces.
• Download the companion mobile app and walk through setup steps.
• Customize alert settings and create schedules for when you’re home, away, or sleeping.

Most systems can be up and running in under an hour, with no tools or drilling required.

3. Add Visible Deterrents

Criminals often look for easy targets—and simple visibility can make a big difference. Consider:

• Security decals or yard/window signs (even if your system is unmonitored)
• Leaving a light or smart plug on a timer if you’ll be away frequently
• Positioning cameras or sensors where they can be seen without being intrusive

These subtle cues let others know your apartment is protected—even if they don’t know exactly how.

4. Customize Your Alerts

Take a few moments to fine-tune your mobile notifications:

• Decide which triggers should alert you immediately (e.g., door opens, motion detected)
• Test each alert type to make sure they’re going to the right device
• If sharing access with roommates or partners, set up separate user profiles or shared codes

This helps you stay informed without getting overwhelmed by unnecessary pings.

5. Establish a Routine

Finally, think about how security fits into your daily habits. This might include:

• Arming your system before bed or when you leave for work
• Doing a nightly lock and window check
• Checking camera feeds at the same time each day

A consistent routine can make your system more effective—and help you feel confident and in control, even in a brand-new space. You can also have a second line of defense for hazards like fire and carbon monoxide—consider adding smoke and carbon monoxide detectors from ADT, which pair with smart hubs and monitoring.

Smart Security Systems with DIY Installation for Renters

Not every apartment allows you to make physical changes—but that doesn’t mean you can’t take control of your own security. Today’s DIY home security systems are specifically designed with renters in mind: no drilling, no hardwiring, and no long-term contracts required.

These systems allow you to customize protection for your space, often within an hour of unboxing. Most include peel-and-stick sensors, wireless indoor cameras, and easy app-based setup that doesn’t interfere with your lease or security deposit.

What to Look for in a Renter-Friendly System

• Tool-Free Installation: Adhesive-backed sensors and mounts that won’t damage walls or doorframes.
• Modular Components: Add sensors, cameras, or environmental detectors over time without buying an entirely new system.
• Remote Access: Arm or disarm the system, view alerts, and check camera feeds from your phone (via app).
• Flexible Monitoring Options: Choose between self-monitoring or optional professional monitoring, depending on your needs and budget.
