Updated September 3, 2026. Quick answer: Not more than one-half acre if within a city plat, otherwise not more than 40 acres in the aggregate; if the homestead’s value at that size is under $500, it may be enlarged in area until it reaches $500.
This is protection against an ordinary money judgment creditor under Iowa Code §§ 561.1, 561.2, 561.4, 561.7, 561.13, 561.16, 561.20, 561.21, a different question from a property tax bill or exemption, which this page does not cover.
How it works in Iowa
- No filing required. Automatic: platting/recording is optional, not required.
- Married couples and joint owners: One shared homestead per household (not one per spouse); a spouse’s concurrence is required to change or convey it, and both spouses must sign to convey or encumber it.
If you sell the home
A replacement homestead bought with the old homestead’s proceeds is exempt up to the value of the old one; no separate time window is stated for cash held before reinvestment.
What it does not protect against
Debts predating the homestead (limited to a deficiency after other property is exhausted), debts under a written contract expressly making it liable, mechanic’s-lien and improvement debts, and (if no survivor or issue) debts it would have owed had it never been a homestead.

Verbatim from Iowa Code §§ 561.1, 561.2, 561.4, 561.7, 561.13, 561.16, 561.20, 561.21: “If within a city plat, it must not exceed one-half acre in extent, otherwise it must not contain in the aggregate more than forty acres, but if, in either case, its value is less than five hundred dollars, it may be enlarged until it reaches that amount.” Read the full official text before relying on any figure here.
