What type of units are required when elevator service only provides access to the lowest story containing dwelling units?

When elevator service only provides access to the lowest story containing dwelling units, it is required to have Type B units. Type B units are designed to be adaptable and accessible for individuals with disabilities, complying with standards that cater to accessibility needs. The focus is on ensuring that at least some units are equipped with features necessary for those who may have mobility issues, facilitating their ability to reside comfortably and safely in the building.

In cases where an elevator only services the lowest level with dwelling units, it is essential to provide accessible units that can be directly accessed from this level. Type A units, on the other hand, are fully accessible but may require access to upper floors that exceed the reach of a single-story elevator service, making them less applicable in this scenario. The other types do not specifically align with the requirements set out for accessible living spaces in buildings where only partial elevator access is available. Thus, the designation of Type B is formulated to ensure compliance with accessibility guidelines while accommodating the building's limitations in elevator access.
