This survey report of the indoor air quality of new California homes reveals that new single‐family detached homes in California are built relatively airtight with very low exterior air-flow, and can often exceed exposure guidelines for air contaminants with indoor sources, such as formaldehyde and some other volatile organic compounds. Mechanical ventilation systems are needed to provide a dependable, continuous supply of outdoor air to new homes, and reductions of various indoor formaldehyde sources are also needed. The following report details the methods of this study, discusses the outcomes, and summarizes the results with several recommendations for improved indoor ventilation.

This document is a report on a CPSC investigation prompted by consumer complaints of air quality problems due to Chinese drywall. The study assessed the environmental conditions in homes with “Chinese drywall” to determine if those conditions could contribute to the health symptoms and material degradation being reported by some residents.
