By that time the farm was being administered by dentist, João Gomes Barreto, who in 1916 hired engineer Henrique Pegado to turn it into a residential town. The current street plan, largely based on a regular grid with 100 m by 100 m blocks, stands to this day, and most streets are still named after the land owners (Rua Evangelina, Rua Doralisa), the administrator (Rua Dentista Barreto), the engineer (Rua Engenheiro Pegado) and their relatives and friends. One street, Rua Francisca de Paula, was named after a former slave of Carrão. The preexisting access road, formerly known as the Itaquera Road, became the present Avenida Conselheiro Carrão, that cuts irregularly across the east edge of the street grid. The residential lots were put up for sale in 1917, which is reckoned as Vila Carrão's official foundation date.
