Understanding Accessible Units, Type A, and Type B Units: A Comparison
Accessible UnitsAccessible Units are designed to provide the highest level of accessibility. These units cater to individuals using wheelchairs, ensuring full access and independent operation within the unit. Here's a closer look:
Overview: Accessible Units are constructed to allow someone using a mobility device to navigate and use the unit independently. These are essential in buildings like hotels, nursing homes, and assisted living facilities, where there is a significant need.
Requirements:
Doors at least 3 feet wide with adequate maneuvering clearances.
Turning spaces in every room.
Knee and toe clearances under sinks in kitchens and bathrooms.
All accessibility features installed at the time of construction.
Type A UnitsType A Units are less accessible than Accessible Units but offer more features than Type B Units. They are designed to be adaptable to meet the needs of residents who may use wheelchairs.
Overview: Type A units are constructed to be wheelchair-friendly with some adaptable features. These units are common in large apartment buildings and offer a compromise between full accessibility and standard residential design.
Requirements:
Doors with clear widths and maneuvering clearances suitable for wheelchair users.
Some fixed accessible features and other adaptable elements.
Blocking for future installation of grab bars.
Type B UnitsType B Units provide basic accessibility and are suitable for individuals who may need minor assistance but do not require a fully wheelchair-friendly environment.
Overview: Type B units are designed for ageing-in-place, suitable for people using walkers, canes, or occasionally wheelchairs. These units do not require full wheelchair maneuverability, focusing instead on general mobility and access.
Requirements:
Doors slightly wider than standard residential doors, providing some ease of movement.
Clearances at fixtures and appliances to accommodate mobility devices like scooters.
No requirements for turning spaces within rooms.
Each type of unit serves a specific purpose, tailored to varying degrees of mobility needs. By understanding the distinctions and specific requirements of Accessible, Type A, and Type B units, developers and builders can better plan and implement housing solutions that cater to the diverse needs of residents with different mobility challenges.
