Another issue is California did not allow insurance companies to increase their premiums so many pulled out.
Our insurance has never gone down or stayed the same. We have had the same company since 1987, get a longevity discount and a multi policy discount, and have never had a claim and our annual premium is just under $3k per year with a $2500 deductible. I believe that it was about ~ $700 when we bought the house. Our house is 2300 sq feet, nothing fancy.
This is not directed at anyone in particular:
When I hear people talking about CA residents like we are not actual people, I have to scratch my head. Where are we all supposed to move that is affordable, safe from natural disasters and near employment centers? Most of us live where we live because we have family and/or jobs tying us to our location. In our case, the gain on the sale of our house is substantial and we're not going to sell and pay tax to the government just so we can move. Plus, where would we move? (Hint - not Truckee lol. It's lovely but I'm not doing snow in my senior years). At at the end of the day, we can't leave our elderly parents anyway - all 4 of ours are still alive and going into their 90s. We are stuck like a cork in a bottle.
In San Diego we had a fire in 2007 called the Witch fire. It "jumped" a 12 lane freeway and burned homes nowhere near the back country or canyons. If you back up to a huge concrete firebreak, you would think you'd be safe, but not in those winds. When the wind speeds get going like what we experienced then, there is not much that you can do other than pray. The embers are carried far away from their source, towards homes that would otherwise seem very safe. That what it looks like in Altadena (my husband's cousin most likely lost his home there the other day - he's still waiting for the official confirmation and hoping that he was somehow spared). Areas that were safe, are safe no longer. We're pretty used to our seasons, and January isn't usually fire season. Things are not like they were when I was a kid, or even a young adult. My entire adult life has had the word "drought" in it every single day. I am sick and tired of it (the money we have spent on saving water!). But that is where we are today, and our heightened fire risk comes with the drought conditions. For other areas, flooding is the issue, for us it's fire. I wish that folks would have a little compassion and not dunk on California residents during an absolute tragedy.
