Accessibility Disputes Are Won With a Tape and a Level
Accessibility cases frequently turn on dimensions: the slope of a ramp, the height of a threshold, the width of a route, or the change in level at a transition. A route that appears usable can still fall outside the permitted tolerances that determine compliance.
Paul Gaston, who holds an ADA compliance certification and has led accessibility remodels in public and commercial facilities, measures as-built walking surfaces, ramps, transitions, and access routes against the applicable criteria, for plaintiff and defense counsel in Chicago and Cook County.
The Measurements That Decide Cases
Built-condition accessibility disputes rest on recorded, reproducible measurements, including:
- Ramp running slope and cross slope
- Changes in level and beveling at transitions
- Clear width of the accessible route
- Handrail height and extensions
- Door maneuvering clearances
- Threshold heights at entries
- Landing size and turning space
A fraction of an inch or a degree of slope can be the difference between compliant and not. That is why these cases are measured, not estimated.

Built Conditions Versus Design and Policy
The evaluation identifies the applicable accessibility requirements referenced by the governing code, establishes the accessible route and the elements at issue, and measures slopes, widths, changes in level, clearances, and handrail dimensions against the permitted tolerances.
Crucially, the analysis stays with the physical, built conditions. Design intent, program access, medical causation, and damages are separate questions that belong to design professionals and other qualified experts.
How Paul Gaston Helps Resolve the Dispute
Paul provides measured accessibility findings against the applicable criteria, with photographs and dimensioned records, for plaintiff and defense. He documents where conditions exceed the permitted tolerances and by how much.
That documented, reproducible record gives counsel a clear factual basis for a claim or a defense, without straying into medical or policy opinions.
Frequently Asked Questions
What accessibility measurements most often decide a case?
Ramp running and cross slopes, changes in level at thresholds and transitions, clear route width, handrail dimensions, and door maneuvering clearances are frequently decisive. These are recorded at representative and worst-case locations and compared to the permitted tolerances.
Is a small slope or threshold difference really a violation?
It can be, because accessibility criteria are defined by specific tolerances rather than general usability. A slope or change in level that exceeds the permitted limit is a documented non-conformance, and the analysis records how far out of tolerance it is.
Does a recent renovation raise the accessibility bar for a space?
Alterations commonly trigger accessibility requirements for the altered elements and, in some cases, the connecting route. The evaluation looks at the scope of the work and the resulting conditions, while questions of design intent are referred to a design professional where needed.
