Mold Inspection in Tukwila, WA

I rent in Tukwila. Can the city look at my unit?

Tukwila runs a Rental Housing Licensing Program through its Permit Center. Rentals need an annual license and a unit inspection before first occupancy and every four years after that, and tenants with concerns about living conditions can ask the program for a courtesy city inspection. The program's page also links tenants and owners to mold resources. Washington law requires landlords to keep units reasonably weathertight and to hand tenants Department of Health-approved mold information, so begin with written notice to the landlord about any leak or dampness. A private inspection can add detail, such as moisture readings and photos, but it isn't required first. This is general information, not legal advice.

Could the 2025 Green River levee breach have affected my building?

The Desimone Levee on the Green River breached on December 15, 2025, during repeated atmospheric river storms. The evacuation order covered the part of Tukwila south of S 180th Street and west of West Valley Highway, a mostly industrial and business area. If water reached your building there, EPA advises assuming mold wherever wet materials couldn't be dried within 24 to 48 hours. An inspector can map damp drywall, flooring and insulation so only what's necessary gets removed.

What does an inspection here usually turn up?

Away from the river, the usual culprits are everyday ones: bathrooms without working exhaust fans, condensation on windows through long gray winters, slow plumbing leaks inside walls, and crawl spaces that stay damp from fall through spring. In apartments, water can travel between units, so the inspector may ask about leaks upstairs or next door. Expect a written report with photos, readings and likely sources, and ask the inspector to separate problems that need removal from areas that only need drying, cleaning or better airflow.

One local note

If the fix involves replacing drywall, framing or plumbing, the City of Tukwila Permit Center on Southcenter Boulevard handles construction permits. Health questions can go to Public Health - Seattle & King County, which doesn't do mold assessments but offers guidance on mold and indoor air.
