New Homeowner Move-In Checklist — Bothell, Washington

You don't know who has copies of existing keys. Rekey or replace all exterior door locks and garage entry.

Find and label the main water shut-off, gas shut-off, and electrical panel. Practice turning them off.

Replace batteries in all units. Replace any unit older than 10 years (smoke) or 7 years (CO). Add detectors if missing.

Install a fresh filter immediately. Note the size and set a reminder to replace every 1-3 months.

Clean the house thoroughly before moving in — especially kitchen, bathrooms, and inside cabinets. An empty house is the easiest time to deep-clean every surface.

Inspect under sinks, around windows, in the basement or crawl space, and attic for water stains or mold. Catching water damage early prevents costly structural repairs.

Take photos and video of every room, including close-ups of any existing damage. This protects you if issues surface later.

Organize warranties, manuals, contractor contacts, paint colors, and appliance model numbers. Or use PropDoctor to track digitally.

Introduce yourself to your new neighbors. Ask about neighborhood norms, trash day, HOA contacts, and recommended contractors. Good neighbor relationships are invaluable.
