Housing in Issaquah and where water damage starts
Issaquah has about 17,542 homes, and half of them were built in 2002 or earlier. Its population dipped 1.0% between 2020 and 2024. Most of the city is newer construction, with 57% of homes built in 2000 or later. Newer homes rely heavily on drywall, engineered flooring, plastic supply lines and appliance connections, so water from a failed hose, water heater or fixture can wick into walls and under cabinets quickly.

Disaster history in King County
