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.
Development of non-profit housing in the United States
Housing trust funds (HTFs) are established at all levels of government (national, state, county and local). These funds are created specifically for the provision of affordable housing to low- and moderate-income households and are based on collected revenue sources. HTFs generally have far fewer restrictions than other forms of public financing and may be used for a wide range of development activities. For example, eligible activities under the National Housing Trust Fund include but are not limited to: property acquisition, development/rehabilitation costs, construction costs, and some operating expenses.
