How Is Accessibility Designed Across Mixed-Use Occupancies?

The engineer and architect divide the residential accessibility work into unit interiors and common areas. Unit interiors follow the Fair Housing design manual: an accessible building entrance, an accessible route into and through each covered unit, doors usable by a person in a wheelchair, an accessible route into and through the unit connecting all rooms, light switches and outlets in reachable ranges, reinforced walls for grab bars, and usable kitchens and bathrooms with the required clearances. The engineer reviews the unit plans against this checklist before they are finalized, since the bathroom and kitchen layouts are where compliance is won or lost. Common areas get the full ADA treatment independently of the commercial occupancies. The residential lobby, corridors, amenity spaces, fitness center, and roof deck each need accessible routes, and where the residential amenities include a pool, the pool needs its accessible entry. The residential elevators are the accessible vertical route — sized and controlled per the elevator code's accessibility provisions — and the engineer ensures the accessible route never requires passing through the retail or office areas. Signage, with raised characters and Braille at the required locations, is specified for the residential common areas as its own package.

Each commercial occupancy's base building provides the accessible shell: accessible entrances with compliant maneuvering clearances, accessible routes through the common areas, accessible restrooms serving the occupancy, and accessible parking on the shortest accessible route to each entrance. The engineer sizes the common restrooms per the plumbing code's fixture counts with the accessibility-required fixtures and clearances, and details the entrances — no steps, compliant thresholds, power-assisted doors where the opening force would otherwise exceed the limit. Tenant spaces carry their own obligations inside the accessible shell. The retail TI provides the accessible sales counters, fitting rooms, and seating; the restaurant TI provides the dispersed accessible seating and accessible service areas; the office TI provides the accessible workstations and break areas its employees need. The engineer documents the base-building/tenant split on the drawings so each TI designer knows the starting point. On the site, the accessible routes connect parking to entrances, entrances to transit stops and public sidewalks, and the occupancies' entrances to each other — all at compliant slopes, all kept clear of service operations, and all maintained as accessible in the property management plan.

Use this checklist before the accessibility design is finalized: • Separate accessible entrances and primary routes designed for each occupancy • Residential unit plans reviewed against Fair Housing: routes, doors, kitchens, bathrooms, reinforcements • Code-required fully accessible units provided beyond the adaptable baseline • Each commercial occupancy's base building: entrances, routes, restrooms, counters per code • Base-building vs tenant-improvement accessibility obligations documented per space • Accessible parking distributed per use on the shortest accessible route to each entrance • Site routes at compliant slopes connecting parking, entrances, transit, and sidewalks • Accessible paths kept independent of other occupancies' secured areas and service operations
