Here is a question that lands differently depending on which side of the lease you are on. For a tenant, it is about safety and autonomy in a home they are paying to live in. For a landlord, it is about property control, liability, and the risk of damage or privacy violations. For a lawyer, it is about a patchwork of state statutes, lease terms, and federal privacy law that varies dramatically by jurisdiction and is still catching up with technology that changes every year.
Smart locks and security cameras are no longer niche products. A 2024 survey by the National Apartment Association found that over 60 percent of newly constructed multifamily units now include at least one smart home feature. Millions of renters want to add their own devices on top of, or instead of, what their landlord provides. Millions of landlords have strong opinions about what that means for their property. And the legal framework governing all of it is a fragmented, inconsistent, and often surprising landscape.
This essay works through the legal reality as it stands, the strongest arguments on both sides of the policy debate, and what the evidence says about where tenant rights over smart home technology should go.
What the Law Currently Says: A Patchwork, Not a Framework
The first thing to understand about renters’ rights to install smart technology is that there is no unified national answer in any English-speaking country. The legal position depends on your lease, your state or province, and the specific type of device you want to install. The debate extends beyond locks — renters asking about smart cameras are often asking the same questions about voice-controlled devices and their privacy implications at the same time.
In the United States, the most relevant legal framework for smart locks comes from state landlord-tenant law governing lock changes. New York State is unusually explicit: Section 51-C of the Multiple Dwelling Law gives every tenant the right to install and maintain a separate lock on the entrance door of their unit, provided a duplicate key is supplied to the landlord on request. Critically, any lease provision that charges a fee for this right is void as against public policy. This is a meaningful tenant protection, but it is specific to New York and does not automatically extend to digital or smart locks in other states.
Most other US states have no equivalent statute specifically covering smart lock installation by tenants. In the majority of jurisdictions, installing or changing a lock without landlord approval violates standard lease terms, regardless of whether the lock is mechanical or digital. Smart locks are treated as lock changes, and lock changes typically require written permission. A tenant who installs a smart lock without approval faces potential lease violation consequences even if the installation caused no physical damage and the landlord retains access.
For security cameras, the position is somewhat more permissive but still highly variable. The American Apartment Owners Association notes that the US Supreme Court has held tenants are generally entitled to install security equipment on exterior parts of a rented building, provided the building is not damaged and other residents are not disturbed. Wireless cameras requiring no drilling are widely considered to fall within tenant rights in most jurisdictions, because they cause no structural change to the property. Hardwired systems, exterior installations requiring drilling, and video doorbells that affect the exterior door frame typically require advance written permission from the landlord.
The federal Electronic Communications Privacy Act (ECPA) provides a floor of protection against illegal interception of communications but does not address the specific question of tenant rights to install recording devices. State wiretapping and recording consent laws, which vary between one-party and two-party consent requirements, apply to cameras in shared spaces and common areas.
In December 2025, the ACLU of Northern California filed suit against major landlord Equity Residential and technology vendor SmartRent, alleging that mandatory landlord-installed smart home systems violated tenant privacy rights by tracking movements and habits without meaningful consent. That case signals where the legal frontier currently sits: not only on tenant rights to install devices, but on landlord obligations around the devices they install themselves.
The Case For: Renters Have a Genuine Safety Interest the Law Should Protect
The safety argument for tenant-installed security technology is compelling and evidence-backed. According to a 2024 National Apartment Association report, tenants in buildings with monitored cameras were 17 percent more likely to recommend their complex to others. The same report found that 70 percent of tenants in buildings with monitored cameras felt those systems prevented crime, a figure 25 percent higher than in properties with passive, unmonitored systems. The security value of cameras and smart locks is not in dispute. The question is who gets to install them and under what conditions.
Renters have reduced autonomy compared to homeowners by definition. A renter is paying, often a very large proportion of their income, to occupy a space as their home. The legal concept of quiet enjoyment gives renters the right to use their home without interference. Restricting a tenant from installing non-invasive security technology on their own front door or interior walls, when that technology causes no structural damage and serves a legitimate safety purpose, sits in genuine tension with the spirit of that right.
Wireless technology has eliminated most legitimate landlord objections. The traditional landlord concern around tenant security installations was about physical damage: drilling holes, running cables, altering the property. Modern smart locks and cameras have largely eliminated this concern. Adhesive-mounted wireless cameras, smart locks that replace existing hardware without structural modification, and video doorbells designed specifically for renters all exist as commercial products engineered to be landlord-friendly. When the physical damage concern disappears, the remaining objection is about control, not property protection.
Jurisdictions that have extended tenant rights have not seen the harms landlords feared. New York’s long-standing right for tenants to install their own locks, with a duplicate key obligation, has not produced waves of property damage claims or disputes attributable to that specific right. The requirement to provide a duplicate key addresses the legitimate landlord concern about emergency access. That model is directly exportable to smart lock installations: the tenant installs the device, provides the landlord with an access code or backup key, and the landlord retains full emergency entry capability.
The Case Against: Landlord Concerns Are Not Simply About Control
Smart devices create data and liability issues that standard lease agreements were not written to address. A tenant-installed smart lock that connects to a cloud service creates a data trail about entries and exits. If that data is accessed, breached, or subpoenaed, the legal question of who owns it and who is responsible for it is genuinely unclear. A landlord who has not consented to the installation of a connected device on their property has not agreed to that data relationship. The ACLU case against SmartRent illustrates the data privacy problem when landlords install devices without meaningful consent. The same problem arises in mirror image when tenants install theirs.
Multi-unit buildings create real privacy conflicts between tenants. A tenant installing a camera that faces a shared corridor, stairwell, or lobby is creating surveillance infrastructure that affects other tenants who had no say in the decision. In a single-family rental this concern is minimal. In an apartment building with dozens of units, unconstrained tenant camera installation creates a patchwork of overlapping surveillance zones potentially covering residents who have reasonable expectations of privacy in shared spaces. The landlord’s role as property manager gives them a legitimate interest in managing that conflict.
Smart lock compatibility and failure creates real technical problems. Not all smart locks are compatible with all door hardware. A tenant whose smart lock fails may face a lockout situation that a standard locksmith cannot resolve. Unlike a mechanical lock failure, a smart lock failure may require technical expertise and can leave a tenant locked out in circumstances where standard remedies do not apply. Landlords who bear responsibility for habitability and emergency access have a legitimate interest in knowing what lock technology is on their property.
What the Evidence Tells Us: The Law Is Catching Up, Slowly
The trajectory is clear. Technology has moved far faster than tenancy law in every jurisdiction. The 2024 National Apartment Association survey showing over 60 percent of new multifamily units already including smart home features means the legal question of who controls that technology is no longer hypothetical. It is a daily lived reality for millions of renters.
The most sensible legal framework emerging from the evidence is a disclosure and non-damage standard: tenants should have the legal right to install non-invasive smart security devices, defined as devices that cause no structural damage and can be removed without trace, subject to a disclosure obligation to the landlord and a requirement that landlord emergency access is maintained. This mirrors the New York lock statute model, extended to smart technology.
A permissive enabling framework, one that creates a floor of permitted installations that leases cannot prohibit while allowing landlords to set reasonable additional conditions, would resolve most of the current legal uncertainty without removing legitimate landlord interests from the equation. The key is distinguishing between invasive installations that alter property and non-invasive devices that do not.
The Verdict: Yes, With a Clear and Workable Framework
Renters should have the legal right to install their own smart locks and cameras, subject to three conditions that address every legitimate landlord concern: the installation must cause no structural damage; the landlord must be informed and must retain emergency access capability; and the device must not surveil shared spaces or other tenants without their consent.
Within those parameters, a prohibition on tenant-installed smart security technology is difficult to justify on any grounds other than the landlord’s preference to control all technology in the property. That preference is understandable but is not, by itself, a sufficient reason to leave renters without the security tools that homeowners take for granted.
The law will get there. The only real question is how much longer the gap between what technology makes possible and what tenancy law permits will remain open, and how many renters will live with preventable security risks in the meantime.
