What is the minimum total number of units in a condominium that requires at least one accessible unit?

In the context of building laws and accessibility requirements, the correct answer indicates that a condominium must have at least one accessible unit when the total number of units reaches a specific threshold. This threshold ensures compliance with accessibility standards set out in regulations, aiming to provide equal housing opportunities for individuals with disabilities.

For a condominium with 26 total units, the requirement for at least one accessible unit aligns with guidelines that typically mandate this accommodation to promote accessibility. The rationale is based on the need to ensure that a certain proportion of residential units are designed to be accessible, thereby supporting inclusivity within the housing market.

As for the other options, they imply different thresholds at which the requirement initiates. A lower number, such as 20 or even 24, would not meet the legal expectations for the provision of accessible units, indicating that the law recognizes 26 units as the minimum necessary to warrant necessary accommodations. The choice of 30 would exceed the actual requirement, making it an unnecessary option for compliance. Overall, 26 units is the specific number recognized for ensuring that at least one unit must be designed to be accessible, balancing the need for accessibility with realistic policy implementation.
