Which coverage you hold decides whether a cracked foundation is a claim or a conversation. Find out before you need it.
If your Florida homeowners policy is from an authorized insurer, you have one of these coverages. You may believe you have the other.
The Short Version: one coverage is required, the broader one is your choice
Catastrophic ground cover collapse is coverage every authorized property insurer in Florida must provide, and it is narrow. Four specific things must all be true before it responds.
Sinkhole loss is optional, broader, and costs extra. Under s. 627.706, Florida Statutes, the insurer must make it available for an appropriate additional premium, but you have to choose it.
Catastrophic Ground Cover Collapse: four tests a claim must pass
All four must be met:
Abrupt collapse of the ground cover. Gradual settlement generally does not meet this test.
A depression in the ground cover clearly visible to the naked eye. If you cannot see the hole, the test is not met.
Structural damage to the covered building, including the foundation. Cosmetic cracking alone is generally not structural damage.
The structure condemned and ordered to be vacated by the governmental agency authorized by law to do so. A condemnation order has to exist.
Read them together and the picture is clear. This coverage is written for the dramatic event: the ground opens, the house is badly damaged, and a government agency orders it vacated. It is not written for the slower scenario of a house developing cracks over a period of years.
Sinkhole Loss: the broader coverage you may think you already have
Sinkhole loss is defined as structural damage to the covered building, including the foundation, caused by sinkhole activity. Contents and additional living expense coverage apply only if there is structural damage to the building.
The definition carries no condemnation requirement, no abrupt collapse requirement and no visible depression requirement. Structural damage caused by sinkhole activity is the test.
That is the coverage you may be picturing when you say "I have sinkhole coverage," and it is the one that is optional.
Deductibles
The statute sets the sinkhole deductible options at 1, 2, 5 or 10 percent of the dwelling limit. The county median owner-occupied home value is $243,100, per the U.S. Census Bureau QuickFacts, but your deductible is based on your own dwelling limit. Work out what each percentage would mean on your policy before choosing a deductible. The hurricane deductible calculator does the same kind of percentage math on any dwelling limit.
Marion County homes: check the coverage instead of assuming it
According to the Florida Geological Survey, sinkholes are a common feature of Florida's landscape. They form where limestone and dolomite bedrock dissolve, a type of terrain called karst. That is reason enough to settle the coverage question for any Marion County home rather than assume it away. Water rising across the yard after heavy rain is a different peril again, and flood cover sits on its own policy.
One honest qualification belongs here. That is a statewide statement, and it says nothing specific about your own lot.
Find Out What You Have: a straight answer, not a sales pitch
Look at your declarations page. If sinkhole loss coverage is in force, it typically appears as its own line with its own deductible, usually expressed as a percentage.
If you cannot find it, it is probably not there. Send the declarations page and you will get a straight answer rather than a sales pitch.
If You Already Have Damage: start with your current carrier
An important sequencing point: coverage generally responds to damage that occurs during the policy period. Buying sinkhole coverage after noticing cracks generally does not cover those cracks. If you are seeing damage now, the conversation is with your current carrier about your current policy, not with a new one.
Questions
Is sinkhole coverage required in Florida?
Catastrophic ground cover collapse coverage must be provided by every authorized property insurer. Sinkhole loss coverage is optional, and the insurer must make it available for an appropriate additional premium.
Can a carrier drop sinkhole coverage at renewal?
An insurer may non-renew sinkhole coverage and offer catastrophic ground cover collapse coverage only, with an actuarially reasonable premium credit or discount. Read renewal paperwork rather than assuming nothing changed, including any roof age question the carrier raises. If the renewal arrives as a non-renewal instead, read what the letter's reason means.
My house has cracks. Is that a sinkhole?
Possibly, and possibly ordinary settlement, tree roots or expansive soil. A determination is an engineering question, not an insurance one, and the carrier's investigation process is the route to answering it. The 4-point report a carrier asks for does not look at the foundation either.
Does it cover my pool or driveway?
Sinkhole loss centers on structural damage to the covered building, including the foundation. Other structures may be treated differently, and the policy language governs.
Should I buy it?
That depends on your parcel, your budget and the deductible you would actually face. What should not happen is finding out which coverage you hold after the damage appears.
