Multifamily Security Laws Across the United States

Multifamily Security Laws

There’s an old axiom in real estate: location, location, location. When it comes to multifamily security laws, the same principle applies. Rules depend a great deal on where the building is located, as both the state and municipality can set them.

Generally, building owners are expected to provide a safe, secure space for tenants and their personal property. The duty of reasonable care legal standard dictates that the owner must take steps to reduce or eliminate risks. At a minimum, that includes a front door with a functioning lock, locking doors on each individual unit, fire exits, and smoke detectors inside each unit. Owners must also protect the building and property from vandalism, loitering, theft, break-ins, and other criminal activity. And federal initiatives like the Violence Against Women Act require landlords to protect tenants who are victims of certain crimes.

But that’s just a jumping-off point. Let’s break down what you can expect from multifamily security laws in various locations.

Multifamily Security Laws by State

Both landlords and tenants can get the basics of a state’s multifamily security laws on any number of websites—organized by state—such as FindLaw, avail, or Nolo. Ignorance of the law is no excuse.

Municipalities may amend or add to state-level regulations, so look at the municipal regulations, too. But states do issue multifamily security laws. They’re typically sweeping and broad, but no less important.  State rules revolve primarily around deposits, leases, eviction procedures, screening, habitable housing, and tenant applications.

They may also include details on the landlord’s expected “due care,” “duty of care,” or “reasonable care.” This is the legal standard that requires you to provide security measures to protect the building, tenants, and property. If you don’t, you may be liable in the event of a crime. That’s especially likely if:

  • The landlord is responsible for the area where the crime took place, like a common room or parking garage
  • There were warning signs that a crime would or might happen (e.g. recent criminal activity)
  • The landlord failed to take easy, affordable protective steps, such as replacing burnt-out lightbulbs or fixing a broken lock

Failure to provide minimal protection can end up being very costly, so don’t wait until it’s too late.

States may also indicate whether rekeying is required. Changing a lock or rekeying it—which involves adjustments to the lock itself so the old key no longer works—ensures previous tenants and employees no longer have access to a unit or building, even if they kept or copied a key. Some states require this process for new tenants, others make it available upon request, and still others don’t mention it at all. For example, New York has no rekeying laws at the state level, but it’s part of California’s state laws.

Multifamily Security Laws by Municipality

Obviously, it would far exceed the limits of this guide to include every municipality in the country. But let’s look at a sampling of major U.S. cities to get an idea of what you can expect. Anyone—landlord, property manager, tenant, interested individual—can find out the local rules by contacting their municipal government.

Think Beyond Minimum Security

As you can see, there is a lot of overlap from place to place. That said, it is your responsibility as a property owner or manager to investigate the local ordinances to ensure your multifamily building is safe, secure, and compliant.

One thing you’ll notice is absent from this sample of municipal regulations is a requirement for security products like cameras and motion detectors. These are typically not compulsory. But—and this is a big but—that doesn’t mean you shouldn’t consider them. As mentioned above, you may be liable for damage, financial loss, and emotional or psychological harm if one of your tenants is victimized in your building and they can demonstrate negligence on your part.

To protect yourself and your tenants, you need to go beyond the minimum requirements.
