Building Green Incentives & Rebates

The following links to incentives and rebates may still be available for your project:


Built Green and LEED Grants

The King County GreenTools program may have funds available for projects that meet their criteria for resource conservation and help educate the public about the importance of green building. Grants between $2,500 - $30,000 for single family and multifamily residential projects seeking Built Green or LEED certification may qualify for a grant award based on the performance level achieved. This is funded through the Department of Natural Resources and Parks.
