What is the maximum net square footage allowed to install a unisex restroom?

The correct answer indicates that the maximum net square footage allowed to install a unisex restroom is 1500 square feet. This standard is typically established to ensure that unisex restrooms provide ample space for accessibility, comfort, and privacy for all users. A 1500 square foot limit allows for a well-designed layout that can accommodate necessary fixtures, circulation space, and additional features such as changing tables or accessibility enhancements.

This standard is essential in various contexts, particularly in commercial and public buildings, to promote inclusivity and ensure that restrooms can effectively serve a diverse population. Larger spaces can enhance the user experience and provide flexibility in design and functionality.

The other options suggest either significantly smaller or larger areas which may not meet the functional requirements or the regulatory guidelines in place, as they could limit accessibility or usability. A smaller size could lead to overcrowding or insufficient amenities, while a larger size might suggest an unnecessary waste of space that does not align with code requirements for restroom facilities.
