The Americans with Disabilities Act (ADA) elevator exemption allows certain buildings to skip the elevator requirement. But the exemption is narrower than most property managers assume, and it comes with conditions that can bite you.
For the full breakdown of ADA elevator requirements -- button heights, cab sizes, Braille, enforcement costs -- see ADA Elevator Requirements. This article focuses only on exemptions.
The 3-Story Rule
Under Title III of the ADA (28 CFR Part 36), private buildings are not required to install an elevator if the building has fewer than 3 stories OR fewer than 3,000 square feet per story. That sounds straightforward. Here is where it gets people.
Every floor must be under 3,000 square feet. One oversized floor disqualifies the entire building. And the exemption only applies to the requirement to install an elevator -- not to any other ADA accessibility requirements for upper floors.
Four categories of buildings are explicitly excluded from this exemption, even if they meet the size thresholds:
- Shopping centers and malls
- Healthcare provider offices
- Public transportation terminals
- Airport passenger terminals
The healthcare carve-out is the most frequently misunderstood. A two-story building with a physician's office on the second floor does not get to skip the elevator. If a tenant provides medical or clinical services, confirm elevator compliance before leasing.
If you already have an elevator, the exemption is irrelevant. You are on the hook for full ADA compliance regardless of building size.
Structural Impracticability
This is the ADA's narrowest exemption. It applies only to new construction and means that the unique characteristics of the terrain or site make it virtually impossible to comply.
"Difficult" or "expensive" does not qualify. Courts have consistently rejected cost or design complexity as grounds. If you are breaking ground and believe this applies, you need a documented site analysis and legal review before you rely on it -- not after.
When Alterations Trigger Elevator Obligations
This catches building owners off guard. When a commercial building undergoes alterations, the path of travel to the altered area must be made accessible. That includes accessible routes, restrooms, telephones, and drinking fountains serving the altered area.
The ADA allows an exception if the accessibility cost exceeds 20% of the alteration cost. Below that threshold, you are expected to make the path accessible.
What this means in practice: renovate a second-floor tenant suite and you may trigger an obligation to improve the accessible route to that floor. Whether that means an elevator depends on scope, existing conditions, and the 20% calculation. Run the numbers before you sign the construction contract.
Title II vs. Title III
Title II covers public entities -- state and local governments, public transit, public schools. The elevator exemption does not apply to them the same way.
Title III covers private businesses and commercial real estate -- hotels, retail, office buildings, medical practices. That is where the exemption lives, and the context for everything in this article. If you are a property manager or CRE (Commercial Real Estate) professional, you are operating under Title III.
The Exemption Does Not Protect You from Lawsuits
A building that qualifies under the 3-story safe harbor still has to comply with every other ADA accessibility requirement: parking, entrances, restrooms, service counters, door hardware, signage. None of that goes away because the elevator requirement does not apply.
And under Title III, covered entities must remove barriers when doing so is "readily achievable." Courts have allowed plaintiffs to challenge exempt buildings on this standard. If a barrier could be removed cheaply -- a threshold, a ramp, a relocated counter -- and it has not been, that is a potential liability regardless of elevator status.
The exemption limits what you are required to build. It does not eliminate your ongoing obligation to remove barriers that are readily achievable to fix.
State codes matter too. Many states adopt versions of the International Building Code that impose elevator requirements stricter than the federal ADA. Mixed-use occupancies and residential buildings four stories or taller frequently face state-level requirements that apply regardless of federal exemption status. Always check both.
Due Diligence Guidance
If you are acquiring a property and the elevator exemption is part of your compliance strategy, that exemption needs to be confirmed -- not assumed -- during due diligence. Exemption eligibility sounds simple (count the floors, measure the square footage), but edge cases exist: mixed-use buildings with a healthcare tenant, prior alterations that triggered unmet obligations, variances with conditions attached, arguable square footage calculations.
An elevator industry professional reviewing equipment history combined with a legal review of building use and configuration gives you a defensible position. A handshake assumption does not.
Even with exemptions, inspections still apply if you have an elevator. Use our checklist to prepare.
