Sinkhole Insurance in Tennessee: Why It's Not on Your Policy (and How to Add It)

Updated 2026-07-04 · by a licensed Lumenbo agent

Most Tennessee homeowners assume a sinkhole would be covered by their homeowners insurance. It isn't — and the surprising part is that the coverage is available in Tennessee; most people just never get offered it. Here's what's going on and how to fix it.

Why sinkholes aren't covered by default

Standard homeowners policies exclude earth movement — a category that lumps together sinkholes, subsidence, landslides, and (separately) earthquakes. So if a sinkhole cracks your foundation or swallows part of your yard and structure, a standard policy treats it as an excluded loss.

This is the same exclusion that leaves earthquakes uncovered in Tennessee — two different perils, one exclusion, and a lot of homeowners surprised twice.

But Tennessee law says insurers must offer it

Here's what most homeowners don't know: Tennessee Code §56-7-130 requires every insurer offering homeowners property insurance in the state to make sinkhole-loss coverage available — for the dwelling and its contents — for optional purchase on request.

The catch words are optional and on request. The law doesn't force carriers to build it into every policy; it only requires them to make it available if you ask. So the coverage exists and is accessible — but it's usually sitting just off your policy, waiting for someone to request it.

Why it's missing from most policies

Because it's optional, a lot of coverage falls through the cracks (no pun intended):

• Big captive carriers (State Farm, Farm Bureau, and others) often don't add it unless you specifically ask — and some don't actively promote it.
• Many independent agencies don't routinely include it either, so it's easy for it to never come up.

The result: a coverage that's required to be offered rarely actually gets added. That's the gap — and it's a differentiator for an agent who proactively raises it.

Who should consider it

Parts of Tennessee sit on karst limestone, the geology most prone to sinkholes. If your home is in a sinkhole-prone area, the coverage protects you from a loss that would otherwise come entirely out of your pocket — potentially a catastrophic one if a sinkhole undermines your foundation. If you're not in a high-risk area, it may be a lower priority. Local knowledge of the ground matters here, which is where a Tennessee agent earns their keep.

How to add it

1. Ask your agent or carrier to add sinkhole coverage — usually done by endorsement.
2. Expect a possible additional premium and, in some cases, a property inspection before the coverage is issued.
3. Confirm what's covered (structure and contents) and the deductible.

It's a straightforward add for most homes. The whole trick is knowing to request it — which now you do.

Ask the question before you need the answer

If no one's ever offered you sinkhole coverage, that's not the same as not needing it.

Frequently asked

Does homeowners insurance cover sinkholes in Tennessee?
Not by default. Standard homeowners policies exclude 'earth movement,' which includes sinkholes, subsidence, and landslides. So a sinkhole that damages your home isn't covered unless you've specifically added sinkhole coverage.

Aren't Tennessee insurers required to offer sinkhole coverage?
Yes. Tennessee law (§56-7-130) requires every insurer offering homeowners property insurance in the state to make sinkhole-loss coverage available for optional purchase on request — including contents. It doesn't have to be built into the policy, but they must offer it if you ask. Many homeowners never ask because they don't know to.

How do I add sinkhole coverage?
Ask your agent or carrier to add it — usually by endorsement. The insurer may charge an additional premium and may require a property inspection before issuing the coverage. It's a simple add for most homes; the hard part is knowing to request it.

Why don't State Farm or Farm Bureau just include it?
Sinkhole coverage is optional, so many carriers don't put it on a policy unless you ask — and some don't actively offer it. Plenty of independent agencies don't routinely add it either. That's exactly the gap: it's available, but it's on you (or a proactive agent) to request it.

Is sinkhole coverage worth it in Tennessee?
It depends on your area's geology and your risk tolerance. Parts of Tennessee sit on karst limestone that's prone to sinkholes; if you're in one of those areas, the coverage can protect you from a catastrophic, otherwise-uncovered loss. An agent who knows the local ground can help you weigh it.
