2019 California Standards for Accessible Design Guide (effective January 1, 2020 with July 1, 2021 amendments)

3. Emergency Transportable Housing

From the Board’s website:

“The Board has issued guidelines for temporary housing provided by the government in emergencies and natural disasters. Emergency transportable housing units, which are designed and manufactured for transport over roadways, have a smaller footprint than other types of housing and pose unique accessibility challenges. Access to such housing was found to be problematic in the aftermath of hurricanes Katrina and Rita in 2005. The new guidelines supplement the Board's ADA and ABA Accessibility Guidelines by adding provisions and exceptions that specifically address emergency transportable housing. The Board developed these guidelines according to recommendations from an advisory panel it organized, the Emergency Transportable Housing Advisory Committee, which included representation from disability groups, industry and code groups, and government agencies. Once these guidelines are adopted into the ABA Standards by the Department of Housing and Urban Development and into the ADA Standards by the Department of Justice, they will be enforceable standards.”
