Tie Down vs Permanent Foundation
A permanent foundation often qualifies a home for standard homeowners coverage. Tie-downs alone usually mean specialized mobile home insurance instead.

Insurers care about whether the home can move. A home bolted to a permanent foundation, one that's been de-titled as real property, is treated more like a site-built house, which is why it can qualify for a standard homeowners policy with broader coverage options. A home resting on piers with tie-down straps to the ground is still legally personal property in most states, even with skirting around the base, so it falls under manufactured home insurance instead. Check your title or deed, and ask your insurer which category your setup falls into before assuming either way.
How your home is set up changes what it costs to insure and what's covered if a storm damages it. Two homes on the same street, one tied down and one on a permanent foundation, can end up with different premiums and different payouts after wind damage. If you're weighing the cost of converting to a permanent foundation, it helps to see what each setup actually pays for first.
What counts as a permanent foundation, and is converting worth it
A permanent foundation usually means the home sits on a frost-protected footing or a full perimeter wall, like a basement or crawl space, with the wheels, axles and tongue removed. Most states follow some version of the HUD foundation certification standard, which an engineer or a certified inspector signs off on. Piers, blocks or tie-down straps alone don't meet that standard no matter how solid they look. If you're not sure what your home has, the certification document or a recent engineer's inspection will say, and your insurer can tell you whether what you have qualifies before you apply.
Converting a tied-down home to a permanent foundation costs real money, often several thousand dollars depending on the home's size and what the ground needs. Some owners do it anyway because a standard homeowners policy tends to offer broader coverage and more insurers competing for the business, which can mean a better price over time. Others find the manufactured home policies available to them already cover what they need, especially if the home is newer and well tied down. There's no single right answer. It depends on how long you plan to keep the home, what conversion costs in your area, and how much the premium difference actually is for your situation.
Retitling matters as much as the physical foundation. In most states, a manufactured home starts out titled like a vehicle, separate from the land it sits on. Converting to a permanent foundation is usually the trigger that lets an owner apply to have the home de-titled as a vehicle and reclassified as real property, folded into the land's deed. Some insurers want to see that reclassification done, not just the foundation work, before they'll treat the home as a standard dwelling. If you're partway through a conversion, ask your insurer which part of the process they're actually waiting on.
If you're buying a home that's already on a permanent foundation, don't assume the paperwork matches. Check that the foundation was certified, not just built, and confirm the title was actually changed if the seller says it was. A home that looks permanently set but was never certified or retitled may still fall under manufactured home insurance, and finding that out after a claim is a bad time to learn it.
What wind and storm damage claims look like under each setup
Wind is where the difference between these two setups shows up most. Manufactured home policies were built around the fact that a home on piers and straps can shift, rack or roll in high wind in ways a site-built house generally doesn't. Because of that, many manufactured home policies either exclude wind and hail entirely in storm-prone areas or price it as a separate add-on with its own deductible. A home on a certified permanent foundation doesn't eliminate wind risk, but it's treated more like any other house, so wind coverage is usually just part of the standard policy rather than something carved out.
Tie-downs themselves matter to a claim even when they're not the issue being argued. Adjusters look at whether the anchoring met the standard required at the time the home was installed, which is usually set by the manufacturer's installation manual and the state or local building code, not a fixed national rule. If a storm damages a tied-down home and the straps or anchors turn out to have been missing, rusted through, or installed to a lower standard than required, that can affect what gets paid. Keeping the installation paperwork or a dealer's inspection record on file is worth doing for exactly this reason.
Skirting adds a wrinkle worth knowing about. It's often treated as an attached structure rather than part of the home's main dwelling coverage, so damage to skirting alone may fall under a different part of the policy with its own limit. Ask whether your policy lists skirting separately and what that limit actually is, since it's easy to assume it's bundled in with everything else.
None of this means a tied-down home is hard to insure or that storm damage won't be covered. It means the policy is built around that setup's real risks, with wind handled on its own terms rather than folded into a general policy the way it would be on a permanent foundation. Reading the wind and hail section of a manufactured home policy closely, including any separate deductible expressed as a percentage of the home's insured value, gives a clearer picture than comparing premiums alone.
One thing to check before you compare
Pull your title or certification paperwork and see which category it actually documents, foundation or personal property. That's what your insurer will ask for first, and it decides which quotes are worth comparing.
