Use this skill for plan-view accessibility checks. It is not a full legal ADA compliance review; apply only the geometric rules provided by the task.
Plan-View Checks
- Door clear opening: compare the submitted clear width against the minimum in the rules file, commonly 32 inches.
- Door swing: if the rule disallows swing into required fixture clearance, prefer an outward or sliding swing in the repaired layout. Do not leave an inward repaired swing unless you have explicitly modeled and cleared the swing path against fixtures and required clearances.
- Turning space: verify that a 60 inch diameter circle fits inside usable floor area. Diameter alone is not enough. Apply the wall/boundary offset from the rules, subtract protected or blocked fixtures such as tubs, and allow overlap with toilet clear floor space only when the rules say so.
- Lavatory overlap: allow the turning circle to overlap a lavatory only when plan-view knee/toe clearance is explicitly indicated and meets the required width and depth.
- Toilet centerline: measure from the adjacent side wall and keep it inside the rule range, commonly 16 to 18 inches.
- Grab bars: classify rear-wall and side-wall bars by orientation/location and compare their plan-view lengths against the minimums. The side-wall grab bar should align with the same adjacent side wall used for the toilet centerline and overlap the toilet use zone. The rear-wall grab bar should align with the rear wall behind the toilet and cross or closely span the toilet centerline.
Violation Reporting
Report one violation per failed rule/element pair. Use stable machine-readable rule names from the rules file, for example:
