Adding Smart Locks and Video Doorbells to Rental Properties — Permission Process and Recommended Equipment

Demand for Security Upgrades in Rental Properties Is Growing

With the increase in package deliveries and the spread of remote work, interest in entryway security is on the rise. Smart locks and video doorbells were previously equipment designed for newly built condominiums, but now demand for retrofitting them to rental properties is surging.

However, installing equipment in rental properties faces two barriers: the "obligation to restore the property to its original condition" and "prior permission from the landlord." This article provides a detailed explanation of the steps and precautions for retrofitting smart locks and video doorbells to rental properties.

What Is a Smart Lock?

A smart lock is a device that attaches over an existing lock and can be opened and closed using a smartphone app or PIN code. Representative products include the following.

Representative Products

• •Qrio Lock: Operated via smartphone app; attaches over the existing thumb turn
• •SwitchBot Lock: Compatible with Alexa and Google Home
• •SADIOT LOCK: Features auto-lock functionality

Characteristics of Retrofit Installation

• •Most attach using double-sided tape or clamps, so no holes need to be drilled in the door
• •Battery-powered, so no electrical work required
• •Most can be easily removed for restoration to original condition

What Is a Video Doorbell/Intercom?

It is an intercom system that allows you to see video of visitors. There are types that replace existing phone-line intercoms and camera-type models that are installed in addition to existing systems.

Types of Retrofit Installation

1. Replacement type: Removing the existing unit and replacing it with a new one. May require electrical work.
2. Adhesive camera type (such as Ring Video): Can be installed without drilling holes, but requires batteries or charging.
3. Smartphone-linked type: Sends a notification to your smartphone when someone arrives, allowing you to view the visitor on screen.

Legal and Contractual Considerations for Installation in Rental Properties

Restoration to Original Condition Obligation

When moving out of a rental property, you have the obligation to restore the property to its original condition "before you moved in." The following rules are basic for smart locks and retrofit video doorbells.

• •Installation without drilling holes: With double-sided tape or clamp systems, restoration is usually possible.
• •Installation with holes: If drilling holes in a door or wall, you must obtain prior permission from the landlord.
• •Marks and damage upon move-out: Tape marks and equipment damage may also be subject to restoration costs.

Steps for Getting Landlord Permission

Step 1: Research the installation method in advance

Before consulting with your landlord, confirm the product specifications (whether holes are required, whether it is removable). Choosing a product that requires no holes makes it easier to obtain permission.

Step 2: Submit a written request to the management company or landlord

Rather than speaking verbally, submit a written request via email or document that clearly states the following:

• •The product name and model number of the equipment you wish to install
• •The installation method (no holes required, double-sided tape/clamp system)
• •How you will restore the property to original condition upon move-out (removal and disposal of tape marks)

Step 3: Obtain written approval

If permission is granted, do not rely on verbal approval alone. Confirm the "installation approval" in writing or via email. This is essential for preventing problems at move-out.

Tips for Getting Landlord Approval

Choose Products That Require No Holes

Emphasizing that "no holes will be drilled in the door" significantly lowers the approval bar. Products like Qrio Lock and SwitchBot Lock can be installed by clamping onto the thumb turn (the inside knob), so there is no damage to the door.

Commit to Restoration Upon Move-Out

Including a sentence in your request stating "I will remove the device and restore it to its original state upon move-out" will reassure the landlord.

Explain How Improved Security Contributes to Property Value

Gently conveying the perspective that "improved security reduces vacancy risk and maintains property value" is more likely to be received positively by the landlord.

Practical Tips for Choosing a Smart Lock

Verifying Thumb Turn Size Is Critical

Most smart locks attach to the existing thumb turn (the inside knob). However, not all products are compatible with every thumb turn shape. Before purchasing, it is essential to verify the shape and size of your own thumb turn and select a compatible model.

Many manufacturers include "spacers" to accommodate various shapes, but some shapes may not be supported, so advance verification is necessary.

Check Battery Life

Since smart locks run on batteries, there is a risk of being locked out if the battery dies. Choose a product with a battery life of at least 6 months, or select one with a low-battery notification feature.

Consider Whether You Need Auto-Lock Functionality

Auto-lock is convenient, but it also carries the risk of being locked out if you accidentally leave without your key. Consider whether you really need this feature, and have backup cards or physical keys available for emergencies.

Practical Options for Retrofit Video Doorbells

Ring Video Doorbell

A product under Amazon (US-based), this is a rechargeable or battery-powered video doorbell. It can be installed by simply adhering a small mounting bracket to the wall next to your door, with minimal drilling required (just 1-2 screw holes). When someone visits, you receive a notification on your smartphone and can view the video or speak to the visitor.

Note: A Wi-Fi connection is required. Also, for rental properties, you need landlord approval for screw installation on exterior walls or door frames.

Wireless Door Cameras (Various Manufacturers)

There are also smart camera types that install using the existing peephole from the inside of the door. By utilizing the existing peephole (door viewer), many models can be installed without additional drilling, making them an option that is easier to get approval for in rental properties.

Precautions After Installation

Verify Building Rules

Some condominium buildings restrict changes to the design of unit entrance doors in their management rules. If you are adding equipment visible from outside (especially a video doorbell), you may need to check with the building's management association (in the case of a condominium rental).

Responsibility for Maintenance and Repairs

Responsibility for failure, dead batteries, or malfunctions of retrofitted equipment is basically yours. If problems remain with the wall or lock after you remove the equipment upon move-out, you risk having to pay for repairs.

Summary: Safe Upgrades with No-Drill Equipment and Written Permission

Retrofitting smart locks and video doorbells to rental properties is possible in most cases if you follow the correct steps.

• •Choose products that require no holes
• •Get written permission from the management company or landlord
• •Commit in writing to restoring the property to original condition upon move-out

By following these three points, you can improve security while avoiding problems at move-out. If you are considering a security upgrade, I recommend first confirming the product specifications and then consulting with the management company early.
