Does California require earthquake insurance for HOAs?

There is no California statute that requires a homeowners or condominium association to carry earthquake insurance. The Davis-Stirling Common Interest Development Act, the body of law in California Civil Code sections 4000 and following that governs these associations, sets floors for general liability, directors and officers, and fidelity coverage, but it sets no earthquake mandate at all. So the direct answer to a board asking whether the state forces them to buy quake coverage is no.

The confusion usually comes from two real obligations that sit next to the coverage question. First, the recorded governing documents, the declaration and the CC&Rs, sometimes do require the association to carry earthquake coverage, and that private contract can bind the board even though the state does not. Second, Davis-Stirling requires the association to tell owners every year whether it carries the coverage. Neither of those is a statutory mandate to buy it, but both are easy to mistake for one.

Standard property and master policies exclude earthquake. Shake damage is not part of the base building coverage, so an association that wants it buys it separately, either as a standalone earthquake policy, as a difference-in-conditions (DIC) policy that also picks up flood and other excluded perils, or by endorsement through a specialty market. A board that assumes the master policy already responds to a quake because the building is insured is reading the declarations page wrong.

This coverage behaves differently from the rest of the master program in one way that dominates the decision: the deductible is a percentage of the insured building value, not a flat dollar amount, and it runs high. Percentage earthquake deductibles commonly land in the 10 to 25 percent of insured value range. On a multimillion-dollar building that means the retained loss before the policy pays anything is very large, which is exactly why the buy-or-decline question is a genuine board discussion rather than a default.

The firm obligation Davis-Stirling does impose is transparency. California Civil Code section 5300, which governs the annual budget report the association must distribute to members, requires that report to include a summary of the association's property, general liability, earthquake, flood, and fidelity insurance policies. Earthquake is named specifically in that list. The summary states the type of coverage, the policy limits, and the deductible, and it carries the statutory caution that owners should not rely on it as a full description of coverage.

The practical effect is that whether or not the association carries earthquake insurance, it has to tell owners each year where things stand. If the association declines the coverage, that fact lands in front of every owner in the annual budget report, which is the moment a homeowner can decide whether to pursue earthquake coverage on their own individual policy. A board that quietly drops or never carries quake coverage without surfacing it in the annual disclosure has a compliance problem independent of the coverage decision itself.

Separately, Civil Code section 5810 requires the association to notify members as soon as reasonably practical if certain coverage lapses, is cancelled, or is not immediately renewed, which reinforces that the state's lever here is member notice, not a purchase requirement.

Boards often ask about the California Earthquake Authority (CEA), the state-established residential earthquake insurer created after the 1994 Northridge quake. The CEA is real and it is a primary market for residential shake coverage, but it writes policies for individual residential structures, single-family homes, individual condominium units, renters, and mobile homes. It does not insure an association's common elements or a master program.

That distinction matters because it splits the exposure across two different buyers. A CEA policy an individual owner buys covers that owner's unit interior, loss assessment, and personal property exposure to a quake. It does nothing for the building structure and common elements the association is responsible for. So even in a community where many owners carry CEA coverage individually, the association's structural earthquake exposure is uninsured unless the board places a separate earthquake or DIC policy through the private specialty and DIC markets. The two decisions are independent, and one does not backstop the other.

When a board does evaluate the coverage, the percentage deductible, not the premium alone, is where the decision is usually made. Translate the stated percentage into dollars against the current insured building value before anything else, because that figure is what the community would have to fund from reserves or a special assessment before the policy responds to a quake.

A high percentage deductible on a large building can mean the coverage pays nothing on all but a catastrophic event. That is a legitimate reason a board might conclude the premium does not buy meaningful protection, and it is also a legitimate reason a board might buy it anyway, since the events it does respond to are the ones that can bankrupt an association. Either way the deductible structure, more than the limit, is the term worth shopping, because a lower percentage deductible often is not available at a workable premium and that constraint drives the whole analysis.

Start with the governing documents. Read the declaration's insurance article before treating earthquake as optional, because if the CC&Rs require the coverage, not carrying it is a covenant breach rather than a discretionary risk decision, and that changes the board's exposure entirely.

If the coverage is genuinely discretionary, treat the decision as a documented board action. Where the community declines earthquake coverage, record that it was a deliberate, disclosed decision rather than a lapse, reflect it in the annual budget report summary that Civil Code 5300 already requires, and tell owners so they can weigh CEA or other earthquake coverage on their individual policies. Where the community carries it, confirm the percentage deductible in current dollars each year and make sure owners understand that the master earthquake policy still leaves their unit interior and loss assessment exposure for their own policy to fill. The through-line is that California hands this call to the board and the governing documents, not to a statute, and the board's job is to make the call deliberately and disclose it.
