The ADA technical infeasibility exemption lets a facility owner skip full compliance with the 2010 Standards for Accessible Design on a specific element when the building’s structure or fixed site conditions physically prevent that element from being brought up to code. It is narrow. It applies element by element, never to a whole project. And even where it applies, the alteration still has to comply to the maximum extent the building allows.
What Counts as Technically Infeasible
Section 106.5 of the 2010 ADA Standards defines “technically infeasible” as an alteration that has little likelihood of being accomplished because the existing structural conditions would require removing or altering a load-bearing member essential to the structural frame, or because other physical or site constraints make it impossible to add elements that fully comply with the standards.1ADA.gov. 2010 ADA Standards for Accessible Design – Section: 106 Definitions Two paths qualify: structural impossibility and site-constraint impossibility.
Structural impossibility is the clearer of the two. If achieving compliance would mean cutting through or removing a steel beam, a reinforced concrete column, or another member that holds the building up, the modification qualifies. The question is the physical reality of the frame, not the cost or difficulty of the work.
Site constraints cover the other category. Property boundaries, immovable underground utilities, elevator shafts, and similar fixed conditions can prevent compliant construction no matter the budget. The operative word in the definition is that the constraint must prohibit compliance. A condition that only makes the work harder or more expensive does not meet the threshold.
Situations Where the Exemption Typically Applies
The exemption surfaces most often in older buildings that were never designed for modern accessibility. Consider a few recurring scenarios.
A load-bearing wall may sit exactly where a compliant 32-inch clear doorway needs to go, and removing enough of that wall could compromise the floor above.2ADA.gov. 2010 ADA Standards for Accessible Design – Section: 404 Doors, Doorways, and Gates The exemption then applies to that specific doorway, not to any other doorway in the project.
Ramps are another frequent trigger. The 2010 Standards cap ramp running slope at 1:12, meaning one inch of rise for every twelve inches of run.3U.S. Access Board. Chapter 4: Ramps and Curb Ramps An entrance sitting three feet above grade needs a ramp at least 36 feet long. If a property line, public sidewalk, or underground utility vault sits 15 feet from the door, there is no room for a compliant ramp. The site itself is the barrier.
Restroom reconfigurations run into this problem too. Achieving the required turning radius and fixture clearances may be blocked by a main sewer stack or elevator shaft that forms part of the building’s core. Moving those elements is not just expensive; it is structurally destructive, which is precisely what Section 106.5 contemplates.
You Still Have to Comply to the Maximum Extent Feasible
An infeasibility finding on one element does not lift the standards for the rest of the work. Section 202.3 of the 2010 Standards states that where full compliance is technically infeasible, the alteration must still comply “to the maximum extent feasible.”4ADA.gov. 2010 ADA Standards for Accessible Design – Section: 202 Existing Buildings and Facilities Get as close to the standard as the building allows.
If a load-bearing member prevents a full 32-inch clear opening at a doorway, widen the doorway as far as the structure permits. If a ramp cannot reach 1:12 because of a site constraint, build to the least steep slope the available space allows. The exemption covers only the gap between what you achieved and what the standard requires, and only for the element where the physical barrier exists.
Every other component of the renovation must meet the 2010 Standards in full unless that specific component independently meets the infeasibility threshold.5U.S. Access Board. Guide to the ADA Accessibility Standards – Chapter 2: Alterations and Additions – Section: Technical Infeasibility An exemption for ramp slope does not relax the requirements for handrail height, tactile warning strips, or any other feature that can be built to spec. Claims most often collapse right here: an owner treats one infeasibility finding as permission to relax everything nearby.
Physical Impossibility Is Not the Same as Cost
Technical infeasibility gets confused with the separate “disproportionate cost” rule, and the two operate on different logic. Technical infeasibility is about physical impossibility. The cost rule is about money. Treating them as interchangeable is how compliant-looking projects end up out of compliance.
The cost rule applies only when you alter a “primary function area,” meaning any space where the facility’s main activities happen: the dining area of a restaurant, the sales floor of a store, exam rooms in a medical office, or classrooms in a school.6U.S. Access Board. Guide to the ADA Accessibility Standards – Chapter 2: Alterations and Additions When you alter one of these areas, you must also provide an accessible path of travel from the altered area to the entrance, including restrooms, telephones, and drinking fountains serving that area.
That path-of-travel work is required only up to 20 percent of the total cost of the alteration to the primary function area.7ADA.gov. ADA Title III Technical Assistance Manual Spend $100,000 renovating the dining room, spend up to $20,000 on path-of-travel accessibility. Once you hit that cap you can stop, but the improvements have to be prioritized: an accessible entrance first, then the route to the altered area, then at least one accessible restroom, and so on.
Cost is never a factor in a technical infeasibility analysis. The ADA Title III Technical Assistance Manual says so directly.7ADA.gov. ADA Title III Technical Assistance Manual If compliance is physically possible but expensive, the infeasibility exemption does not apply. Look to the 20 percent cap instead, and only if the work touches a path of travel to a primary function area. For anything else, full compliance is required regardless of expense.
Documenting an Infeasibility Claim
The burden of proof rests on the facility owner, so documentation carries the claim. You need a structural engineering report that identifies the specific members or site constraints blocking compliance. Architectural drawings should show the physical conflict with accurate measurements demonstrating that the required dimensions or slopes cannot be met. A licensed professional must provide written justification explaining why the constraint is insurmountable rather than merely inconvenient.
Each element claiming the exemption needs its own separate paperwork. A blanket statement covering the whole project will not survive review. For every element, the documentation should identify the ADA code section that cannot be met, describe the physical barrier, and explain what level of compliance was achieved instead. That last piece speaks to the maximum-extent-feasible requirement, and reviewers look for it.
The package goes to the local building department during permitting. Officials review the engineering justification against the Section 106.5 definition before issuing a permit. An exemption request without supporting documentation from a qualified professional will hold up the permit until the file is complete.
Keep the records. Approved forms, professional assessments, and permit documentation belong in the permanent project file for the life of the building. Federal investigators or private plaintiffs can request them years after the renovation to test whether the exemption was legitimately claimed. Without those records, the owner has no defense.
What Happens if the Claim Fails
The stakes justify the paperwork. As of July 2025, the maximum civil penalty for a first violation under ADA Title III is $118,225, and a subsequent violation can reach $236,451.8Federal Register. Civil Monetary Penalties Inflation Adjustments for 2025 These figures adjust annually for inflation. The $75,000 cap cited in older materials has not applied since 2014.
Enforcement moves along two tracks. The Department of Justice can pursue penalties through its own investigations, and private individuals can file lawsuits alleging accessibility violations. Either way, the facility owner has to prove the exemption was properly claimed and documented. Unsupported infeasibility claims do more than fail as a defense; they can be treated as evidence of intentional non-compliance, which pushes penalties toward the maximum.
