Whether the dwelling coverage on your policy would actually rebuild your house — and what a shortfall costs you at claim time. Planning estimate only, not an appraisal.
Your renewal jumped and the carrier said 'rates went up.' Here is what is actually driving it, how to tell whether yours outran your state's, and the four levers that genuinely move the number.
Flood and earth movement are excluded from every standard homeowners policy — and the clause that excludes them is written so a wind-and-water loss can be denied entirely. Here is what is out, and what fills each gap.
Non-renewed, cancelled, or declined: read the notice correctly, stop force-placed insurance, fix the reason code on it, and get the house insured again in 30 days.
The exact sequence to run when your house is damaged — mitigation, documentation, the claim call script, the adjuster visit, reading the estimate, and every escalation step in order.

From Home Insurance in California: What It Costs and What Actually Covers You
In California this is not one item on a checklist. After a total loss it is the thing that determines whether you rebuild.
Your Coverage A dwelling limit should equal what it would cost to rebuild your home from the foundation up at current local construction prices. It is not:
In California, market value and rebuild cost diverge more than anywhere else in the country, because so much of a California home's price is the dirt underneath it. California's median home price is $904,640. The cost to rebuild a typical home is a fraction of that. A homeowner who insures to the purchase price wildly overpays for coverage they can never collect; a homeowner who insures to a lender-driven minimum can be short by hundreds of thousands.
Rebuild cost in California runs around $320 per square foot, the midpoint of a published $215-$430 range. It covers materials, labor, and general contractor overhead and profit, and excludes land.
For a 2,000 square foot home:
That $430,000 spread is the widest in this dataset except one, and the width is the point. California carries a genuinely distinct cost band, but coastal metros sit near the top of that range and inland counties near the bottom, so a single statewide number is unusually lossy here. A Bay Area rebuild and a Bakersfield rebuild are not the same project. Use $640,000 as a starting point and adjust hard for your actual market.
Two California-specific adjustments on top:
Most homeowners policies contain a coinsurance provision requiring dwelling coverage of at least 80% of full replacement cost to be paid replacement cost on a partial loss. Below that threshold, your partial claim is cut proportionally.
Work it on the 2,000 square foot home:
Now a fire does $100,000 of damage — smoke, a partially burned wing, not a total loss. You are far below your $450,000 limit, so you expect $100,000 less your deductible.
Instead:
And on a total loss, underinsurance is worse still and simpler: you receive your limit, and the gap between your limit and the actual rebuild cost is yours to fund. That is exactly what happened to large numbers of California homeowners after the major fires of the last decade, and it is the most predictable, most preventable financial disaster in this market.
Re-check your dwelling limit against current construction costs every single year. In a period of construction-cost inflation, a limit that was adequate three years ago can slip below the coinsurance threshold with you doing nothing at all.
