ALPHARETTA — A local nonprofit plans to celebrate 20 years of serving the area this fall and has invited the community to join in the event.

Habitat for Humanity North Central Georgia will hold a prayer breakfast featuring Ravi Zacharias, the globally-recognized founder of Ravi Zacharias International Ministries, from 7:30 to 9 a.m. Oct. 6 at the Metropolitan Club in Alpharetta.

The event will coincide with World Habitat Day, which has been set aside by the United Nations to recognize the basic right of all humanity to adequate shelter.

Habitat for Humanity’s local outreach branch is a not-for-profit, Christian housing ministry that builds affordable homes available for purchase by low-income families who “demonstrate the capacity for responsible homeownership.”

Since its inception in 1995, the organization has completed 270 homes serving an estimated 1,000 family members in Forsyth, Cherokee, Dawson counties and the north Fulton area.

Families are not given free homes. They are working families who earn between 30 and 60 percent of the Atlanta-area median income and buy homes at or near appraised value with a 30-year no-interest financing provided by Habitat.

Each “partner family” must also attend educational classes and perform 200-300 hours of construction “sweat equity” on their home.

The anniversary event is open to the public, with tickets available for $25.

Tickets are limited and can be purchased through the Habitat-North Central Georgia website at habitat-ncg.org.
