It depends on the climate and the quality of installation. In a dry climate, it may last for 50 years or more; in a humid climate, it may only last for 25 years or so. Good quality stucco should last for 40 years or more.

The answer to this question really depends on the climate where you live, as well as on the quality of the stucco application. In general, traditional stucco should last anywhere from 15 to 30 years with proper maintenance.
