Paris is meaningfully harder than Los Angeles. Residents moving between these cities should adjust dishwasher salt settings, descaling frequency, and boiler service schedules.

Moving from Los Angeles to Paris?

If you're relocating from Los Angeles to Paris, expect visible limescale on taps and shower heads within weeks. You'll need to recalibrate your dishwasher's salt setting, increase kettle descaling frequency, and check your boiler warranty requirements. A shower filter and under-sink scale inhibitor are worth considering immediately.
