Sunnyvale, Texas
Sunnyvale is a town in eastern Dallas County, situated about 14 miles east of downtown Dallas and just south of Garland, along the shore of Lake Ray Hubbard. It has retained a largely low-density, semi-rural residential character within the Dallas-Fort Worth metropolitan area, distinguished by larger lots and open land. The lake and surrounding creeks shape much of its eastern edge.
Property here runs through the Dallas Central Appraisal District and the county tax office — the homestead exemption, the appraisal cap, protests, and any MUD, PID, or special districts all sit at the parcel level. The Dallas County notes below cover the practical details, with the official county directory for the appraisal district and tax office.
