Habitat for Humanity
There are 95 million Americans who live in unfit or unstable housing. Worldwide, that number explodes to one billion [source: Habitat for Humanity]. For 35 years, Habitat for Humanity has used volunteer crews to build and maintain simple homes for families who need a fresh start.
Habitat for Humanity is always looking for qualified baby boomers with construction, carpentry, architecture or design experience to join its work crews across the United States. If you don't have the right work experience, you can still help out as a "gofer" on the job site.
In addition to its flagship construction program, Habitat also offers two-week international volunteer opportunities through its Global Village program. Even RV enthusiasts can get in on the act: A program called RV Care-A-Vanners allows road-roaming boomers to sign up with work crews for two-week build projects, including disaster relief.
