In federal law, “per accommodation” carries two distinct meanings depending on the regulation using it. In property and building codes, it means per individual unit — each hotel room, each rental apartment, each sleeping space. In disability law, it means per individual adjustment a business makes so a person with a disability can access its goods or services: one sign language interpreter here, one ramp there, one policy change for a third customer, each treated as its own obligation. Which meaning applies depends entirely on whether the rule governs physical property standards or civil rights duties.
The Per-Unit Meaning in Property and Building Codes
When fire safety and building regulations use “per accommodation,” they are counting dwelling units. The requirement attaches to each room or sleeping space inside a larger property, not to the property as a whole.
Smoke alarms are the clearest example. The National Fire Alarm and Signaling Code requires smoke alarms inside every sleeping room, outside each sleeping area, and on every level of a home or lodging unit.1National Fire Protection Association (NFPA). Installing and Maintaining Smoke Alarms A hotel does not satisfy the rule by installing alarms in common areas; the obligation runs room by room. Guest rooms designated to provide accessible communication features carry additional requirements, with alarms that meet audible and visible notification standards.2U.S. Access Board. Comparison Between the ADA and IBC Chapter 7
The practical effect is that compliance is counted and inspected per unit. One deficient room is a violation even if every other room on the property meets the standard.
The Per-Request Meaning in Disability Law
Under the Americans with Disabilities Act and its implementing regulations at 28 C.F.R. Part 36, “accommodation” refers to a specific change a business provides so a person with a disability can use its goods or services on equal terms.3eCFR. 28 CFR Part 36 – Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities – Section: Subpart C—Specific Requirements Each accommodation is a separate obligation. A business must evaluate every request on its own facts rather than applying a blanket policy that answers all requests the same way.
That per-request framing matters because the facts vary. A customer asking for a Braille menu, a patient asking for a qualified interpreter during a medical appointment, and a guest asking that a “no animals” rule be waived for a service animal are three distinct accommodations. Each requires its own analysis of what the person needs, what the business can provide, and whether an alternative would work.
What Counts as an Accommodation
Federal regulations group the obligations into three categories, and the per-accommodation principle governs each one.
The first is modifying policies, practices, or procedures. A store with a “no animals” rule must allow service animals. A restaurant that normally requires customers to serve themselves at a buffet must bring food to a wheelchair user’s table when standing in line is not workable.3eCFR. 28 CFR Part 36 – Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities – Section: Subpart C—Specific Requirements
The second is providing auxiliary aids and services when a person needs help communicating or accessing information. These include qualified sign language interpreters, screen reader software, large print materials, audio recordings, and assistive listening devices.3eCFR. 28 CFR Part 36 – Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities – Section: Subpart C—Specific Requirements The business generally chooses the aid, but the aid has to actually work for the person in the setting. A written note may be fine at a hardware store counter and inadequate in a medical consultation, so the per-accommodation analysis has to look at the real situation, not the label of the aid.
The third is removing architectural and communication barriers in existing facilities where doing so is “readily achievable” — able to be carried out without much difficulty or expense.4Office of the Law Revision Counsel. 42 USC 12182 – Prohibition of Discrimination by Public Accommodations and in Commercial Facilities Whether removal is readily achievable depends on the facility’s size and type, the business’s overall resources, and the nature and cost of the change. When full removal is not readily achievable, the business must offer the goods or services through an alternative method if one exists. This is not a one-time assessment. What was too expensive one year may be affordable the next, and the obligation refreshes with the business’s circumstances.
Why “Per” Does Real Work in Disability Law
The word matters because the law refuses to let a business answer requests in bulk. A policy of “we never allow animals” cannot defeat a service animal request. A standing refusal to provide interpreters cannot defeat a request from a deaf patient. Each request gets its own look, with its own answer, backed by its own reasoning.
Documentation reinforces this. There is no prescribed federal format for recording Title III accommodation requests, but a usable file includes the date and nature of the request, how the business evaluated it, any alternatives considered, the decision, and the reason for any denial. The record demonstrates that the business ran the required analysis for that specific accommodation rather than reflexively applying a rule.
When a Business Can Say No
Per-accommodation review does not mean every request is granted. Two defenses are built into the statute, and both are decided one accommodation at a time.
A business may decline a policy modification or auxiliary aid if providing it would “fundamentally alter” the nature of its goods or services, meaning the change would turn the business into something materially different from what it normally offers.4Office of the Law Revision Counsel. 42 USC 12182 – Prohibition of Discrimination by Public Accommodations and in Commercial Facilities A business may also decline an auxiliary aid if providing it would create an “undue burden,” meaning significant difficulty or expense judged against the business’s resources.3eCFR. 28 CFR Part 36 – Nondiscrimination on the Basis of Disability by Public Accommodations and in Commercial Facilities – Section: Subpart C—Specific Requirements
Neither defense works as a blanket rule. Each denial requires an individualized assessment of the specific request, the specific business’s resources, and whether a less costly alternative would meet the need. “We’ve always done it this way” is not a defense, and neither is discomfort on the part of other employees or customers.
No Surcharges, Per Accommodation
A business cannot bill the person who needs an accommodation for its cost. Federal regulations prohibit surcharges to cover auxiliary aids, barrier removal, or policy modifications.5ADA.gov: Americans with Disabilities Act. Americans with Disabilities Act Title III Regulations – Section: Subpart C – Specific Requirements A sign language interpreter, a wheelchair ramp, and a Braille menu are all absorbed as costs of doing business.
The rule carries over to service animals. A hotel that charges a pet deposit or cleaning fee must waive it for guests with service animals, though the hotel may still charge a guest for actual damage the animal causes, on the same terms as any other guest who causes damage.6ADA.gov. ADA Requirements: Service Animals
Reading the Phrase in Context
When you encounter “per accommodation” in a regulation, lease, inspection report, or compliance checklist, the context tells you which meaning applies. A fire marshal counting smoke alarms is counting units. An ADA compliance officer evaluating a complaint is counting adjustments. The two meanings do not conflict, but they do govern different duties, and treating one as the other produces the wrong answer. A hotel that installs an alarm in every room has satisfied the per-unit rule and may still owe a per-request accommodation to a deaf guest who needs a visual alarm in the specific room assigned to them.
