Seattle’s Deconstruction Ordinance

In Seattle, residential deconstruction permits have strict requirements: 20% minimum reuse of materials by weight, 50% minimum recycled/reused, 100% of concrete/asphalt/brick recycled/reused, and waste diversion planning.

In October 2022, Seattle launched a pilot incentive program providing $4,000 per qualifying residential deconstruction project using approved contractors. Eligible projects include complete house/duplex removal requiring demolition permits, with historic landmarks having additional criteria. Seattle’s approach combines requirements and financial incentives to make deconstruction more viable than demolition.
