Anchoring (tie-downs)

Anchoring, often carried out with tie-downs, is the system of straps, ground anchors, piers, and foundation components that secures a manufactured home against wind, flooding, overturning, and lateral movement.

Anchoring is largely a matter of installation standards. Many states adopt uniform installation rules — frequently administered by a single state agency — requiring that a home be installed on a permanent foundation able to resist specific forces such as wind, flood, flotation, sliding, and lateral movement. The detailed tie-down specifications usually live in the agency's rules rather than in the statute itself, and local rules typically cannot override the statewide standard.

Anchoring is related to, but distinct from, being permanently affixed. Anchoring is about safety and resisting forces; being permanently affixed is about legally attaching the home to land, which can matter for title retirement. A home can be properly anchored on a rented lot without being permanently affixed to it.

For how a specific state handles installation, see its storm guide. This is general information, not legal advice.
