Habitat for Humanity is a charitable nonprofit organization dedicated to building simple, low-cost homes by forming partnerships with low-income families in need of decent and affordable housing. The organization believes homeownership is a vital step to help families break the cycle of poverty and contributes to pride in families and communities. You don't need to be an expert in construction or a committee subject area to help out. There are many tasks that require only a willingness to learn and work with others. However, kids must be 16 years or older to help on the construction sites, and there must be one adult at a work site for every two kids. Due to the wonderful popularity of Habitat for Humanity, there is generally a two- to three-month wait to volunteer on a construction site.
