Circulation and clearance planning

Planning workflow

1. Mark primary and secondary routes as visible bands on the plan.
2. Add door, drawer, appliance, and furniture movement envelopes.
3. Test the plan with the actual occupants and mobility needs in mind.
4. Compare the result with locally applicable accessibility, egress, and residential requirements.

Formula or decision logic

A route is viable only when its clear width remains available after open doors, projections, and placed objects are considered. For a rectangular turning test, compare both clear dimensions with the selected planning envelope; for a circular test, compare the clear diameter. These are design tests, not declarations of legal compliance.

Worked planning example

A 42-inch corridor appears generous, but an 18-inch-deep console reduces a local segment to 24 inches. Moving the console into a recess restores the continuous path. For a resident using a mobility device, model the device and maneuvering needs directly and have applicable requirements reviewed.

Limitations and review boundary

• ADA Standards do not automatically govern every private residence.
• Local residential and accessibility rules differ.
• Furniture, handles, slopes, thresholds, and user abilities affect real usability.
