Water Past Exterior Walls, Etc. Stucco, exterior siding, exterior walls, including, without limitation, exterior framing, and other exterior wall finishes and fixtures and the systems of those components and fixtures, including, but not limited to, pot shelves, horizontal surfaces, columns, and plant-ons, shall be installed in such a way so as not to allow unintended water to pass into the structure or to pass beyond, around, or through the designed or actual moisture barriers of the system, including any internal barriers located within the system itself. For purposes of this paragraph, "systems" include, without limitation, framing, substrate, flashings, trim, wall assemblies, and internal wall cavities, if any This Performance Standard provides that various exterior components are to be installed to control the flow of water and prevent the introduction of what is described as "unintended water" into the home. With proper use and proper maintenance of these components of your home, you should expect good performance consistent with this standard. The exterior walls and components of your home are intended to respond to weather conditions, including handling of water that falls or runs on their surfaces. It is the expectation of the design and construction industry that water will be controlled but some of that water will enter the system without causing unanticipated problems. As such water is anticipated to pass the primary moisture barriers, such as an exterior stucco wall system, only to reach a secondary barrier, such as building paper or other systems, it is not considered "unintended water" which would be a violation of this Performance Standard. It is anticipated that water will pass the exterior or primary weather barrier and wet the internal or secondary barrier for a period of time, and then either flow away or dry up within the system. It is also anticipated that significant weather and storm systems may bring heavy downpours and/or wind- driven water, which could overwhelm the water resistant systems associated with these exterior components. As explained elsewhere in these Performance Standards, Homebuilder is not responsible for violations of these standards caused by a weather condition which is in excess of the design criteria expressed by the applicable building codes, regulations and ordinances in effect at the time of the original construction of your home. For the proper use of your home, it is also important that you avoid the use of hoses or otherwise introduce w...
