It's all part of the Habitat for Humanity's 31st annual Jimmy and Rosalynn Carter Work project which began Sunday and ends October 11th.
In Fort Worth, the focus will be on the Central Meadowbrook neighborhood. Mayor Betsy Price will be building Monday morning alongside President Carter.
In Dallas, the focus will be on East Oak Cliff. Mayor Mike Rawlings will be building Thursday morning alongside President Carter.
"People who have everything in life, they want to come out and work for a week side by side with a family who've never had very much. Now, they're getting a new glimpse on what life can be and gives them hope and self-respect and anticipation for the future and that's a turning point," said President Carter.
He turned 90 last week and jokingly jabbed at the mayors of Dallas and Fort Worth for only volunteering to build one day, when President Carter says he and his wife will work five days.
