Single limit vs. multiple limits: a CEA homeowners policy states one combined single limit (CSL) as the most it pays for all covered loss under Coverage A (dwelling) and Coverage B (extensions to dwelling). Money paid under one reduces what remains for the other. Other limits, such as personal property and loss of use, are separate. With multiple limits, each coverage would have its own amount that the other cannot draw on.
Reduced coverage: California's minimum earthquake offer is narrower than a homeowners policy. Its dwelling coverage may leave out outbuildings, swimming pools, many masonry fences and walkways, landscaping and similar items (Section 10089(a)(1)).
The deductible is a percentage of the combined single limit, not of the loss. Only dwelling-type losses count toward meeting it; personal property does not help. Under the Standard policy, personal property is not paid if the deductible is not met. Loss of use has no deductible.
The deductible comes off the loss, not the limit. Example: CSL $400,000 with a 15% deductible ($60,000). A $460,000 dwelling loss pays $460,000 − $60,000 = $400,000. A $500,000 loss gives $440,000 after the deductible, which is capped at the $400,000 limit.
