Facility Security Plan: A facility security plan that matches the building

March 2, 2026 · Ken Armstrong

45 CFR 164.310(a)(2)(ii) sets the expectation for facility security plan. The text is brief; the evidence it implies is not, and the difference between the two is where most remediation time goes.

What the rule says

Facility security plan (Addressable). Implement policies and procedures to safeguard the facility and the equipment therein from unauthorized physical access, tampering, and theft.

That is the text of 45 CFR 164.310(a)(2)(ii). Read it closely: it describes an outcome to achieve, not a product to buy, which is why two practices of the same size can satisfy it in different ways and both be right.

This is an addressable implementation specification, and addressable does not mean optional. Under 45 CFR 164.306(d)(3) you assess whether the specification is reasonable and appropriate in your environment, and then either implement it or, if implementing it is not reasonable and appropriate, document why and implement an equivalent alternative measure if that is reasonable and appropriate. The documented reasoning is itself part of the requirement, so an undocumented decision to skip it is the finding.

What this looks like in practice

In an assessment, 45 CFR 164.310(a)(2)(ii) is not one question. It resolves into several, and each one is really asking for different evidence. These are among the questions asked about it:

Does the organization define and protect physical security perimeters around areas that house sensitive information and supporting equipment, or, where it has determined that this safeguard is not reasonable and appropriate, documented that determination and implemented an equivalent alternative measure (45 CFR 164.306(d)(3))?
Does the organization monitor its physical environment to detect potential physical security events affecting systems that handle sensitive data, or, where it has determined that this safeguard is not reasonable and appropriate, documented that determination and implemented an equivalent alternative measure (45 CFR 164.306(d)(3))?
Does the organization place and protect the equipment that holds or accesses ePHI to protect it against reasonably anticipated environmental hazards and unauthorized physical access?

Ownership usually sits with whoever controls building access, though the evidence is often produced by someone else, which is where the trail breaks. A control that works but has no owner tends to stop working the month the person who quietly maintained it changes roles.

Who this applies to

Every covered entity and every business associate, at any size. 45 CFR 164.306(b) allows flexibility of approach, so a two-provider practice and a hospital system may implement this differently and both comply. What flexibility does not allow is skipping the decision: the smaller the organization, the more the written reasoning carries the weight, because there is no scale of operation to make the control self-evident.

Building it, in order

These steps are one way to meet it, drawn from our question bank. Unless a step names a provision, the Security Rule does not require that particular measure: 45 CFR 164.306(b)(1) lets you use any security measures that allow you to reasonably and appropriately implement the standards and implementation specifications, chosen with the factors in 45 CFR 164.306(b)(2).

The sequence below is the order that produces evidence as a by-product rather than as a separate documentation exercise:

Identify and document the physical perimeter of each area containing sensitive information or supporting equipment. Where the organization determines this safeguard is not reasonable and appropriate, record that determination and the equivalent alternative measure implemented, as 45 CFR 164.306(d)(3) provides.
Ensure perimeters are physically sound, with walls, controlled entry points, and barriers that prevent unauthorized entry.
Protect equipment and the premises from tampering and theft.
Periodically inspect perimeters for weaknesses and remediate gaps.
Deploy monitoring of physical entry points and secure areas, such as door alarms or cameras where appropriate. Where the organization determines this safeguard is not reasonable and appropriate, record that determination and the equivalent alternative measure implemented, as 45 CFR 164.306(d)(3) provides.
Define what constitutes a physical security event and how alerts are handled.

Where else this maps

The questions behind 45 CFR 164.310(a)(2)(ii) also map to NIST SP 800-66 Rev. 2 5.2.1, 5.2.3, which is voluntary guidance rather than law; following it does not by itself establish compliance with any law. That matters for scoping: the same evidence can be written once and referenced from each, rather than rewritten per framework.

Evidence an assessor asks for

For this requirement the evidence types that satisfy it are policy, procedure, and risk assessment. The distinction matters more than it looks: a policy states what you intend to do, a procedure states how, and a record proves it happened on a date. Auditors ask for all three, and a practice that has written the first two often has nothing for the third.

Date every document and keep the superseded versions. 45 CFR 164.316(b)(2)(i) requires the documentation 164.316(b)(1) calls for (the Security Rule policies and procedures, and the written record of any action, activity or assessment the Security Rule requires to be documented) to be retained for six years from the date of its creation or the date when it last was in effect, whichever is later, so a policy you replaced two years ago is still part of the record.

Where this usually goes wrong

The most common failure here is treating addressable as optional. A practice decides the specification does not fit, implements nothing, and writes nothing down. At assessment the answer to "why not" is a verbal explanation, which is not evidence. The second most common failure is the opposite: implementing an alternative that works, and still not recording the reasoning, so the control looks accidental.

What to do about it

Produce the evidence, not the intention. For 45 CFR 164.310(a)(2)(ii) that means a signed, dated policy with a named owner and a review date, a step-by-step procedure someone unfamiliar with the task could follow, and a completed assessment showing the method, the findings and the date. If the only evidence is that someone knows how this works, you have a practice and not a record.
Put a name on it. Whoever controls building access should be recorded as the owner. Where the work is done by someone else, say so in the document: the split between who owns it and who performs it is where the trail usually breaks. A control with no owner stops working the month the person who quietly maintained it changes roles, and nobody notices.
Set a review cadence and keep the evidence of each review. An annual date with a dated output is a common floor; what fails an assessment is a control implemented once and never re-checked against a changed environment.
If you decide not to implement it, write the decision down. Addressable is not optional: under 45 CFR 164.306(d)(3) the documented assessment IS part of the requirement, so an undocumented decision to skip it is the finding, and a working alternative with no recorded reasoning looks accidental.

Work backward from the evidence. Decide what evidence would prove facility security plan to someone who does not already trust you, then build the control that produces it. Programs built in that order tend to stay current, because the evidence goes stale visibly.
