Why is HOA insurance so expensive in California right now – and will it get better?

Two forces drive it, and both are about supply rather than anything specific to one association. Fewer carriers are competing for California association business than a few years ago, particularly for property in or near wildfire-exposed areas. When fewer carriers quote, pricing power shifts toward the insurers still writing, and renewals can come back higher even where nothing about the property changed. Replacement values have also risen, and a master policy is priced against the cost to rebuild, so when the insured value goes up the premium follows even at an unchanged rate. Practically, that means association renewals in wildfire-exposed areas are being quoted differently than they were, and some are placed outside the standard admitted market. Whether the market loosens, and when, is not something we will predict. California has regulatory changes underway intended to bring capacity back, and the effect on any particular association is something to judge at its renewal rather than in advance. What is within your control is the file a carrier underwrites: a current replacement cost valuation, documented maintenance and any wildfire mitigation work, and a clean loss history. Those are worth assembling before a renewal rather than during it.
