About this chapter: Chapter 9 is intended to prevent moisture from adversely affecting occupant health and safety and the structural and functional performance of a building. This chapter deals with both the liquid and vapor forms of water.
To safeguard people from injury and protect the building or other property from damage caused by surface water and to protect outfalls of drainage systems that may become contaminated from on-site hazardous material storage.
Building or building sites used for the storage or use of hazardous materials shall include provisions to ensure that hazardous materials are not accidentally transported across property lines into drainage outfalls.
To safeguard people against illness or injury that could result from accumulation of internal moisture, and to protect an occupancy from damage caused by free water from another occupancy in the same building.
An adequate means shall be provided to remove excess moisture from the structure or protect it from the effects of excess moisture and condensation in all habitable spaces, bathrooms, laundries and other locations where moisture is potentially generated.
