The purposes of this chapter are the following:

1. (1) To encourage and foster the utilization of the resources and capabilities of private enterprise and of individual and group self-help techniques in the rehabilitation and replacement of deteriorated and dilapidated housing and in the construction of additional housing in both urban and rural areas.
2. (2) To stimulate housing rehabilitation and construction so as to increase the supply of decent, affordable housing.

3. (3) To demonstrate that improved housing conditions, ownership, and maintenance are within the financial capabilities of persons and families of low or moderate income through the reduced costs of owner-building, owner-rehabilitation and other self-help-oriented alternatives.

   Nothing in this chapter shall be construed as preventing participation of renters in such housing alternatives.
