Montrose Chemical vs. Admiral Insurance (1995) 10 Cal.4th 645
In the context of continuous or progressively deteriorating property or bodily injury losses insurable under a third party CGL policy, as long as there remains uncertainty about damage or injury that may occur during the policy period and the imposition of liability upon the insured, and no legal obligation to pay third party claims has been established, there is an insurable risk within the meaning of sections 22 and 250 for which coverage may be sought under such a policy.

Montrose Chemical vs. Superior Court (1993) 6 Cal.4th 287
Supreme Court has concluded that "[t]he insured's desire to secure the right to call on the insurer's superior resources for the defense of third party claims is, in all likelihood, typically as significant a motive for the purchase of insurance as is the wish to obtain indemnity for possible liability.

Presley Homes vs. American States Insurance Company
Plaintiff Presley Homes, Inc. sued defendant American States Insurance Company seeking damages, plus declaratory and injunctive relief.  Defendant cross-complained against plaintiff for declaratory relief.  The action involves a dispute over the extent of defendant’s obligation under the additional insured endorsements of two insurance policies to provide plaintiff with a defense in a third party’s construction defects lawsuit. Plaintiff was entitled to have defendant provide a defense to the entire action as a matter of public policy. To defend meaningfully, the insurer must defend immediately. To defend immediately, it must defend entirely.  It cannot parse the claims, dividing those that are at least potentially covered from those that are not.  To do so would be time consuming.

Garriott Crop Dusting Co. v. Superior Court
There is a duty to defend, because the test of an "occurrence" of property damage under the CGL policy is not when the plaintiff was injured, but rather when the land was damaged. 

Aas vs. Superior Court (The William Lyon Company)
The court held that other "economic damages" would not be recoverable under a negligence theory. This means that homeowners and associations can no longer recover the cost of repairing structural problems in homes until physical damage occurs.

Coverage - Attorneys' Fees - Damages
Golden Eagle Insurance Company v. Insurance Company of the West (Court of Appeal, Fourth District - June 26, 2002)
This case states it is the first to hold that attorneys' fees and costs awarded pursuant to an indemnity agreement and insured under a contractual liability provision are "damages" under a general liability policy. (Caselaw)

STEARMAN, JEFFREY N. et al., vs. CENTEX HOMES
A defendant builder of mass produced housing may be held strictly liable for construction defects.  This question is firmly established in California cases beginning 30 years ago. The court held that the damage plaintiffs sustained to their home is physical injury falling outside the parameters of economic loss and is thus compensable under strict liability in tort. The order denying plaintiffs’ motion to recover expert fees as damages is reversed.  The judgment in favor of plaintiffs is modified to include an additional $37,500 representing those damages.  As so modified, the judgment is affirmed.  Plaintiffs shall recover their costs on appeal.
