Our goal is to ensure every one of our neighbors has a happy, healthy place to call home. Together, let’s make our communities the best they can be.


Get Involved and Give Back

We love to build. Homes. Businesses. Better communities. You get the idea.

What do you want to build?

Business relationships, brand awareness, community connection – these things and more are available for you and your business. The avenues of involvement are limitless, as are the impacts you can make for yourself, your community and our region. How far can the MBA take you? It’s up to you.



One of two signature stewardship events, each May member captains and volunteers create free wheelchair ramps for those in need throughout King and Snohomish counties.

Since 1993, 415+ ramps have been built, including a record 37 individuals and families in 2016.

Painting a Better Tomorrow™

Community organizations need to look their best, too. One day in November, members and volunteers help paint a public building or site in need of upgrade.

250,000+ square feet have been painted since 2009, with $80,000 saved in time and labor.

Housing Hope

In order to make sure everyone has a happy home, members can get involved in Teambuilds as well as annual fundraising events and projects.

Commitment in the Community
In 1999, the Master Builders Association of King and Snohomish Counties became one of the first building associations in the country to start a green home certification program, called Built Green. See what we’ve done at

Action in the Building

Waste Reduction
Composting cans in every meeting room send the waste from 9,000 meals per year to composting facilities, not the landfill. Wasteful lunch boxes are out, food trays and catered lunches are in, saving hundreds of pounds of waste yearly. Recycling cans greet visitors in every meeting room, common area and office.

Energy Conservation
A comprehensive energy audit on our 30,000-square-foot building will aid us in creating strategies that will help us save the most operating energy.

The building is cleaned exclusively with Greenseal Certified cleaning products to ensure good indoor air quality. To reduce dust and water use, high efficiency and water conserving vacuums are used for both carpet and hard surface floors.

The bulk of the plantings at the Housing Center are native and drought tolerant. In 2014 we reduced water use by 25 percent and non-organic fertilizer use by 100 percent.

Leadership Through Socially Responsible Investment
The Master Builders Association dedicates a portion of its overall investment portfolio to a Socially Responsible Investment Fund specializing in clean, renewable energy production and conservation. We are proud to invest in companies which are researching and designing the technology that will help bring us to a sustainable future.

Passion to Create the Mercer Slough Environmental Education Center
In April 2011, Master Builders Association members joined together with the city of Bellevue, the Pacific Science Center and other local leaders for the official ribbon-cutting of Wet Lab II at the Mercer Slough Environmental Education Center in Bellevue. The building currently serves as a hands-on educational center.  


Construction Education Scholarship Program

The Master Builders Association is committed to encouraging students seeking education related to the home building industry by awarding scholarships for qualifying technical, community college and university level programs.
