Large parts of East and Middle Tennessee sit on limestone, the rock that dissolves into sinkholes. Many homeowners assume their policy already handles that risk. Under Tennessee Code § 56-7-130, sinkhole coverage is something insurers must offer, not something every policy automatically includes.
| Rule | What § 56-7-130 says |
|---|---|
| Must insurers offer it? | Yes, every insurer offering homeowner property insurance must make sinkhole coverage available, including contents |
| Is it automatic? | No. It is for optional purchase on request |
| How it is added | In the policy, by endorsement, or through other coverage; the insurer may charge extra and may inspect first |
| Not a sinkhole loss | Land stabilization costs, and cracking or similar damage without structural damage |
| Before a denial for inconsistency | Written certification from an engineer, professional geologist, or other qualified individual |
| Bad-faith claim cost | 50% of the analysis, capped at $2,500, and only after a warning and a chance to withdraw |
| Repair contract deadline | Within 90 days after the insurer confirms coverage |
| Paying for repairs | Insurer pays as the work is performed; no advance payment by the policyholder |
| Repair completion | Generally within 12 months after the repair contract |

Coverage is offered on request
The statute says every insurer offering homeowner property insurance in Tennessee must make coverage available for insurable sinkhole losses, including the contents of the dwelling. It also says nothing in the section mandates that sinkhole coverage be included in a homeowners policy. The duty is to make it available for optional purchase when the policyholder asks. In practice that means you should look at your declarations page and endorsements, not assume.
The insurer may provide the coverage in the policy itself, by endorsement, or through other coverage it arranges, and it may charge for it. It may also require an inspection before it issues sinkhole coverage. For how endorsements change a policy, see TDCI glossary: an endorsement can expand or limit policy benefits.
What counts as a sinkhole loss
The law defines a sinkhole loss as structural damage to a covered structure caused by the sudden collapse of the earth supporting it as the result of sinkhole activity. The definition leaves out land stabilization costs, and it leaves out cracking, shrinking, expansion, or deterioration when there is no structural damage to the building. A cracked driveway or a settling patio on its own is not the same thing as a sinkhole loss under this section.
How a sinkhole claim has to be investigated
When a claim comes in under a policy with sinkhole coverage, the insurer must inspect the premises. If it concludes the structural damage is inconsistent with sinkhole activity, it must first get a written certification from an engineer, a professional geologist, or another qualified individual before denying the claim.
There is a cost rule for policyholders, too. If the analysis finds the damage was not caused by sinkhole activity and the claim was submitted without good faith grounds, the policyholder reimburses 50% of the cost of the analysis, capped at $2,500 per claim. That applies only if the insurer warned the policyholder about it before ordering the analysis and offered the chance to withdraw the claim.
Repairs, payments, and deadlines
Once a covered sinkhole loss is verified, the insurer may limit payment to actual cash value, excluding stabilization and foundation work, until a repair contract is signed. The policyholder must enter into a contract for stabilization and foundation repairs within 90 days after the insurer confirms coverage. After that, the insurer pays as the work is performed and may not require the homeowner to advance payment for covered repairs. Repairs generally must be finished within 12 months of the contract, with listed exceptions that include mutual agreement, a claim in litigation, and a claim under appraisal or mediation.
The law also lets an insurer cancel, nonrenew, or decline to issue coverage on a structure with a sinkhole claim if it was not repaired according to the approved plan and timeline, or if it is at risk of future sinkhole damage because of unstable land.

Does Tennessee homeowners insurance automatically cover sinkholes?
Not necessarily. Tennessee Code § 56-7-130 requires insurers offering homeowner property insurance to make sinkhole coverage available for optional purchase on request; it does not require every policy to include it.
How is sinkhole coverage added to a policy?
The statute lets the insurer provide it in the policy itself, by endorsement, or through other coverage it arranges. The insurer may charge extra and may require an inspection first.
Is cracking in my walls or slab a sinkhole loss?
Not by itself. The statute's definition excludes cracking, shrinking, expansion, or deterioration when there is no structural damage to the covered structure, and it excludes land stabilization costs.
Can an insurer deny a sinkhole claim without an expert?
If the insurer concludes the structural damage is inconsistent with sinkhole activity, it must first obtain written certification from an engineer, a professional geologist, or another qualified individual.
Could I have to pay for the engineering analysis?
Only if the claim was submitted without good faith grounds and the insurer warned you beforehand and offered the chance to withdraw. The reimbursement is 50% of the analysis cost, capped at $2,500 per claim.
How long do I have to sign a repair contract?
The statute says within 90 days after the insurer confirms coverage for the sinkhole loss and notifies the policyholder.
Do I have to pay the contractor up front?
No. After the repair contract is signed, the insurer pays as the work is performed, and the statute says it may not require the policyholder to advance payment for covered repairs.
