That’s true. I had to pay to get rain gutters onto my house when I bought it. Houses in So Cal are just wood studs covered with stucco, no basements, inferior insulation. Luckily it doesn’t get too hot or cold here. The older houses build 50 years + ago (North Park, Point Loma, etc…) have no insulation at all and whatever temperature it’s outsite, it’s the same inside.
