East Bay homeowner in complete agreement! Even with no worries about freezing pipes, I made sure there's a washing machine catch-pan with a water-detector. The sump-pump has a water-detector next to it. And yep, the furnace has a water detector, alongside the condensate pump. One for the tankless water heater - even though it's outside. Easy. Driveway & landscaping slope away from the house? Yes. Properly sloped storm-water drains with clean outs? Yes. Leaf-shields & redundant gutter downspouts? Yes and yes.
