House raising
House raising (house lifting, house jacking, barn jacking, building jacking) is the process of separating a building from its foundation and temporarily raising it with hydraulic screw jacks. The process is the first step in structure relocation in which the building is moved to a different location. House raising may also be a part of a renovation to build a foundation under an existing house or make a house larger by building a new floor level creating a two story house. Often employed in areas that are prone to flooding and storm damage, this process can be achieved through the use of either timber piles or helical piles. Once a house is raised and supported on cribbing, a new foundation can be constructed beneath it. After Hurricane Katrina and Hurricane Sandy large numbers of houses in parts of Louisiana, New York and New Jersey were raised to avoid future flooding.
Colonia (United States)
Colonias may lack all of the essential physical infrastructures and public services: clean water, sanitary sewage, and adequate roads. Most colonia housing does not meet construction standards and building codes. Houses are often built little by little, starting as shabby tents of wood and cardboard. Only 54% of colonia residents in Texas have sewer service and about 50% drink water from a non-tap source. Because they do not qualify for financing, Colonia residents buy their land on a contract for deed, in which land ownership stays with the seller until the entire purchase is paid. This land eventually ends up to be worthless as the market for colonia housing is very low. Most houses cannot pass inspections to qualify for repairs and further improvements. The housing situation in Cameron County, Texas lacks certain infrastructure and requires $44 million to upgrade all of the homes. Financially, families living in colonias lack the assets to add improvements in order for sustainability.
