A.5.1.5 Air Conditioning

A. Air Conditioning of residential spaces is required for all properties except in markets located in climate zones where new units without air conditioning are commonly accepted. Where air conditioning is required to provide year-round indoor comfort, assure continued marketability, and prevent premature obsolescence, projects must be air-conditioned. Particular attention should be given to the need for air conditioning and ventilation in elevator structures, especially for senior citizens.
