sharing the housing of others due to loss of housing
economic hardship, or a similar reason
staying in motels, trailer parks, or camp grounds due to the lack of an adequate alternative
staying in shelters or transitional housing; or sleeping in cars, parks, abandoned buildings, substandard housing, or similar settings
