Key Findings

1. Iowa has no comprehensive HOA statute and no percentage cap on assessments. Neither Chapter 499B (condominiums) nor Chapter 504 (nonprofit corporations) sets a ceiling on the size of a regular or special assessment or the rate at which it may rise.
2. Assessment authority and allocation come from the declaration. For condominiums, the declaration fixes each unit's fractional or percentage interest, and the bylaws set the manner of collecting each owner's share. For planned-community HOAs, no statute grants assessment authority — that authority is contractual.
3. Iowa has not adopted UCIOA. The state provides no owner-veto or budget-ratification mechanism and no reserve-study mandate.
4. The condominium lien is not a super-priority lien. Under Section 499B.17, unpaid common-expense assessments take priority over other liens except tax liens of an assessing unit or special district, and sums unpaid on a first mortgage of record.
5. No regulator. Iowa has no dedicated HOA regulator. The Real Estate Commission's rules come into play only when an association engages a manager for brokerage or leasing activity.
6. Recent activity is narrow. Senate File 2448 (2026) amends the Chapter 499C records-access framework. No recent bill or appellate ruling touches assessment limits or the assessment lien directly.

Section 1: Overview

Iowa draws a clear line when it comes to assessment limits: the state does not impose them. There is no statutory percentage cap on assessment increases, no comprehensive homeowners association statute, and the recorded declaration carries nearly all the weight. Condominium regimes operate under Iowa Code Chapter 499B, the "Horizontal Property Act," which a community activates by recording a declaration in the county recorder's office.¹ Non-condominium HOAs — the planned communities — draw their assessment authority from their recorded declaration, supplemented by the Revised Iowa Nonprofit Corporation Act (Chapter 504) where the association is incorporated as a nonprofit.² Special assessments take their authorization and limits from those same documents: the declaration and bylaws, with the Horizontal Property Act supplying lien treatment for condominium common-expense obligations.³

On the national spectrum, Iowa sits firmly at the self-governance end — and that distinction matters. Statutory-cap states such as California set explicit ceilings: Civil Code Section 5605(b) caps board-imposed regular-assessment increases at 20 percent over the prior fiscal year and aggregate special assessments at 5 percent of budgeted gross expenses absent member approval. UCIOA states go further, giving owners a ratification veto over adopted budgets. Iowa grants none of that. The sections below set out where assessment authority comes from, what limits actually apply, the procedures boards use in practice, recent legislative and judicial activity, and where Iowa stands relative to other states.
