Can Tenants Install a Security System Without Landlord Permission?

Home security used to be something only homeowners talked about. Today, millions of renters want safer living spaces too, especially with the rise of package theft, break-ins, and smart home technology. This brings up a big question:

Can tenants install a security system without landlord permission?

The answer is important for tenants who want peace of mind and for landlords who want to avoid liability or property damage.

With over two decades of managing rental properties, I’ve seen both the good and the bad: tenants who installed completely harmless DIY gadgets and others who drilled into doors, rewired units, or created safety and privacy risks. The truth is, most conflicts happen simply because neither side understands the rules.

This article breaks everything down. You’ll learn what renters can install freely, what requires permission, what the law says, how privacy rules work, and how both sides can avoid conflict.

Let’s make security simple, safe, and legally compliant for everyone.

Here’s the Short Answer To Clear This Doubts on Your Mind

Yes, tenants can install certain security devices without permission, as long as they do not damage the property or make permanent changes.

But anything that requires drilling, wiring, replacing locks, or altering the building absolutely does require landlord permission.

The rule of thumb:

• Non-invasive = Usually allowed

These are plug-in, battery-powered, or peel-and-stick.

• Permanent = Needs permission

These involve holes, wiring, mounting, or structural changes. Keep this rule in mind as we dig deeper.

Why This Question Matters Today?

Security concerns have increased across the U.S., especially in rental homes and apartments. With more affordable smart home devices, renters want extra protection.

Here’s why this topic matters right now:

1. Smart Home Devices are Exploding in Popularity

More than 30 million U.S. homes use some type of smart security system, and that number grows every year.

2. Package Theft is Rising

According to recent surveys:

• 41% of Americans have had at least one package stolen
• Most thefts happen in apartment buildings or rental neighborhoods

3. Tenants Want Safer Rentals

A Zillow survey found that:

• 73% of renters say safety features matter more than amenities
• 56% would pay more for a unit with better security.

4. Landlords Want Less Liability

Property owners worry about:

• Damage from improper installation
• Illegal surveillance
• Privacy complaints
• HOA restriction
• Insurance violations

Security systems in rentals clearly matter to both sides, and both have rights. The key is understanding what’s allowed and what’s not.

What Tenants Can Install Without Landlord Permission

Not every security upgrade requires approval. Renters are usually free to install non-invasive, removable, and drill-free devices that don’t alter the property in any way. These products are designed specifically for apartments and rental homes, which means they won’t damage walls, wiring, or structural components.

Below are the most landlord-friendly and legally safe options.

1. Indoor Wi-Fi Cameras (Plug-In or Battery-Powered)

Examples include:

• Wyze Cam v3
• Blink Indoor
• Google Nest Indoor Cam

Why they’re allowed:

• They sit on a shelf, counter, or piece of furniture.
• They don’t require drilling or mounting into walls.
• They don’t modify electrical wiring.
• They’re easily removable when the tenant moves out.

Important Reminder:

Tenants can only record inside their private unit. Recording shared areas (hallways, porches, or the landlord’s property spaces) is usually prohibited by privacy laws.

2. Peel-and-Stick Window and Door Sensors

Common in DIY alarm systems, these sensors use:

• Adhesive strips
• Magnetic contacts
• Battery power

Why they’re allowed:

• No screws, nails, or drilling
• Easy to remove without leaving permanent marks
• No wiring changes or electrical work

Brands like Ring, SimpliSafe, and Abode design these specifically for renters.

3. Smart Home Hubs and Voice Assistants

Examples:

• Amazon Echo
• Google Nest Hub
• Apple HomePod / HomeKit devices

Why they’re allowed:

• They simply sit on tables, nightstands, or counters
• Zero impact on the physical structure
• They only pair with other removable smart devices

These hubs can help control lights, sensors, and cameras without installation into the property.

4. Plug-and-Play DIY Security Kits

Modern DIY systems are built for rental properties. These kits typically include:

• Wireless sensors
• Peel-and-stick hardware
• Battery-powered keypads
• Plug-in base stations

Brands designed for renters include:

• SimpliSafe
• Ring Alarm
• Abode
• Kangaroo

Why they’re allowed:

• No drilling
• No permanent mounting
• No wiring changes
• Quick installation and removal

Tenants can secure doors and windows while keeping the property in its original condition.

5. No-Drill Doorbell Cameras (Select Models Only)

Some companies now offer renter-friendly doorbell cameras that use:

• Strong adhesive pads
• Pressure-mounted brackets
• Wrap-around door mounts

Examples:

• Ring No-Drill Mount
• Eufy No-Drill Video Doorbell Mount

Why they’re allowed:

• No screws or holes in the door or door frame
• No electrical wiring required
• Can be removed without leaving damage

However:

• Tenants should double-check the lease because some landlords consider any doorbell upgrade as modifying the exterior.

Why These Devices Usually DON’T Require Permission

All of the devices above are rare exceptions in the world of rental upgrades because they:

• Cause no permanent damage
• Require no drilling
• Don’t change locks, hardware, or wiring
• Keep the property in its original condition
• Are fully removable at move-out

Most leases allow reasonable, non-invasive improvements that don’t affect the safety, structure, or integrity of the property. These devices fall completely within that category.

What Tenants Cannot Install Without Landlord Permission

While renters have plenty of freedom with non-invasive devices, anything that modifies the property, drilling, wiring, or replacing hardware, almost always requires written permission. These upgrades can create safety issues, insurance problems, and long-term damage, so landlords must be involved.

Below are the systems that always need approval.

1. Hardwired Alarm Systems

Hardwired systems connect directly to:

• Electrical wiring
• Wall systems
• Existing security infrastructure

Why is permission required:

• They alter the structure of the home
• They can interfere with building codes
• They may affect insurance coverage
• Improper wiring can create fire hazards or electrical risks

Any system that runs wires through walls automatically counts as a major property modification.

2. Cameras or Devices That Require Drilling or Mounting

If it requires screws, nails, or holes, it needs approval; no exceptions.

Examples include:

• Wall-mounted indoor cameras
• Drilled brackets for sensors
• Outdoor security cameras
• Floodlight cameras
• Motion lights that bolt into siding

Why landlords must approve:

• Drilling can cause structural damage
• Holes in exterior walls can create water leaks
• Mounted hardware can damage drywall, trim, and siding

Even “small holes” count legally as altering the property.

3. Replacing Locks With Smart Locks or New Deadbolts

This is one of the most legally sensitive areas in rental housing.

Why does it require permission:

Landlords must maintain legal access in emergencies
Changing locks without approval is illegal in many states
Smart locks complicate access: codes, batteries, and lockouts

State laws vary:

Some states allow lock changes if the tenant provides a key, but many prohibit it without explicit permission. When in doubt, assume lock replacements require approval.

4. Wired Doorbell Cameras

Examples:

• Wired Ring Video Doorbell
• Wired Nest Hello Doorbell
• Any doorbell requiring a transformer connection

Why is permission required:

• They connect to electrical systems
• They replace or modify existing doorbell hardware
• Installation requires screws and drilling

Because they alter exterior fixtures, they are treated as a property modification.

5. Cameras Facing Shared or Community Areas

Tenants can record inside their private unit, but not in areas shared with others. Installing cameras that face or capture shared spaces is typically prohibited.

Examples of restricted areas:

• Apartment hallways
• Shared porches or entryways
• Parking lots (varies by state)
• Shared laundry rooms
• Mail or package areas
• Common stairwells

Why are these not allowed:

• They may violate state privacy laws
• They often break lease rules
• They may conflict with HOA or building rules
• They can expose landlords to legal liability

Even harmless intentions, like monitoring package theft, cannot override privacy rules.

6. Exterior-Mounted Security Devices

Anything that attaches to or penetrates the exterior structure requires permission.

Examples:

• Outdoor security cameras
• Floodlights with mounts
• Motion sensors bolted into siding
• Hardwired spotlight cameras

These installations affect:

• Siding
• Brick and mortar
• Trim
• Stucco
• Weatherproofing layers

Because exterior walls are legally protected structures, tenants must get permission before installing anything on them.

What the Law Says (Clear, Simple U.S. Overview)

Every state has its own landlord-tenant laws, but the pattern is almost identical across the country:

Tenants can install temporary, removable security devices.

These include anything that uses adhesive, batteries, or sits on a shelf.

Tenants cannot alter the property without landlord permission.

If it involves drilling, wiring, replacing hardware, or changing locks, it legally counts as a property alteration.

This rule shows up in:

• State landlord-tenant acts
• Standard residential leases
• Local building codes
• Court decisions about rental damage

Many states; including California, Oklahoma, Maryland, Oregon, Texas, and New York, use the same phrase in their statutes:

“Tenants may not make alterations to the property without the landlord’s written consent.”

Security systems fall under “alterations” when they require structural changes of any kind.

This simple rule protects both the tenant’s right to safety and the landlord’s right to prevent damage.

Privacy Laws Tenants Must Follow

Even if tenants install a legal security device inside their rental, privacy laws still apply. Cameras can easily cross legal lines if they capture areas where other people expect privacy. This is where many renters get into trouble, not because of the camera itself, but because of what it records.

Here’s a clear breakdown of what tenants can and cannot do.

Where Tenants Can Legally Record

Tenants may record inside their own private living space, including:

• Their bedroom
• Their living room
• Their kitchen
• Any interior area they exclusively control
• Their private patio or balcony (if it is not shared with neighbors or roommates)

The key rule:

If the tenant pays rent for the space and no one else has access to it, recording is allowed.

Where Tenants Cannot Record

Recording in certain areas is illegal because other people have a reasonable expectation of privacy.

Cameras cannot face or record:

• Shared hallways
• Shared entryways
• Building lobbies
• Community laundry rooms
• Public or community mailrooms
• Neighbors’ doors or windows
• Bathrooms
• Bedrooms shared with roommates or other tenants

Why are these areas off-limits:

• They violate privacy laws
• They may break apartment or HOA rules
• They create legal liability for both the tenant and landlord

Potential consequences include:

• Privacy violation lawsuits
• Police involvement
• Immediate lease termination
• Eviction in serious cases

Audio Recording Laws: A Bigger Issue Than Most People Realize

Video laws are strict, but audio recording laws can be even stricter.

At least 15 U.S. states require two-party (or all-party) consent for audio recording.

Examples include:

• California
• Florida
• Pennsylvania
• Illinois (varies)

In these states, everyone being recorded must agree to the audio being captured.

This means:

• Cameras with microphones may require consent
• Tenants may need to disable audio recording entirely
• Recording someone’s voice without permission can result in fines or criminal charges

Many renters don’t realize:

It’s not the video that gets people in trouble; it’s the audio.

What Happens If Tenants Install Security Systems Without Permission?

When a renter installs a security system that requires landlord approval, but skips that step, several consequences can follow. With over two decades of managing rental properties, here’s what commonly happens and why it matters for both sides.

1. Lease Violation Notice

Most leases clearly state:

“Tenants may not alter the property without written permission.”

If a tenant installs a system that involves drilling, wiring, or replacing devices without approval, it’s considered a lease violation.

2. Required Removal

Landlords can legally require the camera, doorbell, or alarm system to be removed, especially if it alters any part of the property or interferes with existing wiring or hardware.

Some landlords allow smart tech, but only when installation is pre-approved.

3. Security Deposit Deductions

If the installation causes damage, landlords can deduct repair costs from the security deposit. Common deductions include:

• Drywall holes
• Damaged wiring
• Damaged locks or door frames
• Altered siding
• Unapproved doorbell mounts

Any physical damage caused by DIY installation is considered the tenant’s responsibility.

4. Repair Charges

If the damage exceeds the security deposit or the tenant is still living there, landlords can bill for corrective repairs, such as:

• Patching and repainting
• Electrical rewiring
• Hardware replacement
• Fixing drilled door frames
• Restoring original fixtures

Unauthorized installations often require a licensed technician to fix, which increases cost.

5. Eviction (Rare but Possible)

Eviction is not common, but it can happen if:

• The tenant refuses to remove the unauthorized system.
• The device caused major damage.
• The installation created safety or liability issues.
• The tenant repeatedly violates lease terms.

Most property owners prefer to work things out, but legally, repeated or serious violations can lead to removal through the courts.

How Landlords Should Respond to Tenant Security Requests

When tenants ask to install a security system, the way a landlord responds can prevent misunderstandings, conflicts, and liability issues. After managing rentals for more than two decades, here are the best practices that consistently protect both the property and the relationship.

1. Review the Lease First

Before saying yes or no, landlords should check the lease sections related to:

• Alterations
• Lock changes
• Hardware installation
• Drilling or mounting rules
• Smart home or security device policies

If the lease already addresses these issues, it guides the entire decision.

2. Ask for Details About the System

A landlord should never approve a security device without understanding exactly what the tenant wants to install.

Key questions include:

• Is it wired or wireless?
• Does it require drilling or mounting?
• Will it replace existing hardware (locks, doorbells, etc.)?
• Is it installed indoors or outdoors?
• Will the camera face or record shared/common areas?
• Can it be removed cleanly when the tenant moves out?

These details help determine risk, liability, and whether modifications are acceptable.

3. Consider Liability, Codes, and Insurance

Many insurers require landlords to approve all security devices, especially those attached to:

• Exterior doors
• Siding
• Walls
• Wiring
• Locks

Landlords should also factor in:

• Building codes
• HOA/condo rules
• Fire safety requirements
• Emergency access or lock override rules

Failing to assess these areas can create insurance conflicts or code violations.

4. Approve the Installation, with Conditions

If the landlord decides to allow the system, approval should come with clear, written conditions such as:

• Tenant must remove the system at move-out
• All holes must be patched and repaired
• No shared or public spaces may be recorded
• Landlord must maintain emergency access (for smart locks)
• Tenant must confirm compliance in writing

This protects the property while still respecting the tenant’s safety concerns.

5. Offer Safer, Landlord-Controlled Alternatives

In some cases, it’s better for landlords to offer their own solutions rather than allowing tenant-installed equipment.

• Smart alternatives include:
• Landlord-installed exterior cameras
• Upgrade exterior lighting
• Motion-sensor lights
• Improved deadbolts or smart locks
• Peepholes
• A property-wide security system

This gives tenants the security they want, while keeping property owners in full control of installations and liability.

What Tenants Should Do Before Moving Out

To protect their security deposit and avoid disputes, tenants should take care of any installed security systems before leaving. Here’s a step-by-step guide:

1. Remove the System Carefully

Take down all security devices that were installed, including:

• Cameras
• Doorbell mounts
• Sensors
• Smart locks
• Any adhesive-mounted components

Tip: Remove adhesive strips slowly. Using a hair dryer on low heat can soften the adhesive for clean removal without damaging walls or surfaces.

2. Patch Any Holes

If screws or anchors were used, fill the holes and repaint the area to match the original finish. This helps ensure the walls or doors look the way they did before the system was installed.

3. Restore Original hardware

Return or reinstall any items that were replaced or modified, including:

• Locks or deadbolts
• Doorbells
• Switch plates or mounting brackets

The goal is to leave the property in its original condition, just as the lease requires.

4. Return Landlord-Owned Security Equipment

If the landlord provided any security devices, tenants should return them in working condition. This includes:

• Key fobs
• Access codes
• Cameras or sensors
• Smart locks

Failing to return landlord-owned devices could result in deductions from the security deposit.

Final Thoughts on Tenant Security Systems

Tenants can install many security devices without permission, as long as they don’t damage the property or change anything permanently. But anything that requires drilling, wiring, or replacing hardware needs landlord approval.

The key to avoiding problems?

• Tenants should choose non-invasive, removable systems whenever possible.
• Landlords should provide clear, fair guidelines in the lease.
• Both parties should communicate openly before installation.

When both sides work together, rentals stay safe, relationships stay smooth, and everyone enjoys more peace of mind.
