Building Green...a Better Home, a Better World
Master Builders Association

The Master Builders Association of King and Snohomish Counties (MBA) was founded in 1909 by a group of Seattle builders who saw a need to unite to address the many concerns and issues affecting the housing industry.  They shared technology and jointly solved construction problems.  They actively worked with government to develop laws that protected the environment while still providing attractive, affordable communities and homes for the families of the Puget Sound region.

The homes and communities built by members of MBA are today among the most desirable neighborhoods in which to live anywhere in the world.
