Knowing what to do the first day in a new house sets you up for a smooth start. Focusing on safety, utilities, and a few essential rooms beats trying to unpack everything at once.
Step: Walk through and note any damage before unloading
Step: Locate the breaker box, water shutoff, and gas valve
Step: Confirm utilities, water, and internet are working
Step: Rekey or change the exterior locks
Step: Test smoke and carbon monoxide detectors
Step: Set up the beds and one bathroom first
Step: Unpack the first-night box and kitchen basics
Step: Find the nearest store, pharmacy, and urgent care
Priorities for move-in day.
When: Do these the very first day, starting before you unload boxes.
Watch out: Do not skip rekeying the locks on day one; previous tenants, agents, and contractors may still have working keys.
