The HUD manufactured home standards, referred to as the Manufactured Home Construction and Safety Standards (MHCSS), cover the design and construction of all manufactured homes in the United States and contain a number of requirements related to ventilation (HUD 1994). Since these standards have been issued, questions have arisen regarding some of the ventilation-related requirements and their implementation. This report describes a study that addresses some of these questions and provides technical input relevant to their implementation and future revision.
