Idaho HOA Assessment Limits

Section 1: Overview — How assessment authority and limits work in Idaho

Idaho sets no statutory cap on how much a homeowners association or condominium can raise assessments. The operative limit — if one exists at all — lives in the community's recorded declaration, not in state law.

The Idaho Homeowner's Association Act, Idaho Code Title 55, Chapter 32, governs HOA open meetings, financial disclosures, due process, fines, and liens. What it does not do is cap assessment increases or require owners to ratify a budget.¹ For condominiums, the Idaho Condominium Property Act, Idaho Code Title 55, Chapter 15, provides the assessment and lien framework: each unit contributes its share of authorized expenses in proportion to its allocated interest in the common areas, as the declaration specifies.²

Special assessments follow the same rule. The authority to levy them — and any approval threshold — comes from the declaration and bylaws. The statutes add only the lien mechanics.

On the national spectrum, Idaho belongs to the declaration-driven group of states, distinct from statutory-cap states like California (Cal. Civ. Code § 5605) and from states that have adopted the Uniform Common Interest Ownership Act with its owner-veto budget mechanism. The sections below set out where assessment authority originates, what limits apply, the procedures that govern increases, and the legislative and judicial activity bearing on Idaho assessment practice.

Section 2: The assessment framework

2A. Authority to levy and allocate assessments

For Idaho HOAs, assessment authority flows from the recorded declaration of covenants, conditions, and restrictions and the bylaws — not from the Homeowner's Association Act. The Act supplies governance, disclosure, and lien mechanics rather than the power to tax. Section 55-3204 directs that all associations, incorporated or unincorporated, "[d]etermine and establish the amount of assessments in accordance with the governing documents or, in the event the governing documents do not include such language, with the approval of a majority of the members of the homeowner's association."¹ In practice, the board sets the annual assessment through the budget process as the declaration authorizes, and the declaration's allocation formula — equal per lot, by lot size, or by another stated method — controls how the total divides among owners.

For condominiums, the Condominium Property Act places assessment authority in the declaration. Section 55-1505 requires the declaration to state each unit's percentage of common-area ownership and provides for assessments so that "each condominium [is] assessed separately for its share of such expenses in proportion, unless otherwise provided, to its owner's fractional interest in the common areas."³ The management body levies assessments under the declaration and recorded bylaws, and the allocation percentages fixed at recording — based on relative unit value or square footage — govern each unit's share.³ In both community forms, the recorded instrument is the source of the power to assess and the controlling allocation rule.

2B. Limits on regular assessment increases

No Idaho statute caps regular assessment increases by percentage, and Idaho uses no owner-veto mechanism over an adopted budget. Whatever limit exists comes from the declaration and bylaws. Many Idaho declarations give the board authority to set the annual budget and corresponding assessment without a member vote; others impose a stated ceiling or a member-approval threshold above a defined amount. The controlling rule appears in the recorded document, not in the Code.

Section 55-3204 adds one statutory default for unincorporated associations: their bylaws must include a provision that "no fees or assessments of the homeowner's association may be increased unless a majority of all members of the homeowner's association vote in favor of the increase."¹ That is a required bylaw term for unincorporated HOAs — not a percentage cap — and it does not apply to incorporated associations, which set increases per their governing documents, or where those are silent, by majority member approval.¹

The disclosure requirements of Section 55-3205 shape how increases are communicated but do not limit them. An association must furnish a member's assessment-account statement within five business days of a written request and an updated financial disclosure within ten business days of a request, at no charge.⁴ These are transparency duties, not substantive ceilings. If a board exceeds a declaration-based limit or skips a required member approval, the increase may be challengeable as a breach of the governing documents — and Idaho courts interpret governing documents under ordinary contract principles.

2C. Special assessments, emergency assessments, and the declaration

Special assessments draw their authorization and limits from the declaration and bylaws. The statutes supply only how the resulting debt becomes a lien. For HOAs, Section 55-3207 provides that an association "may levy an assessment against a lot for the reasonable costs incurred in the maintenance of common areas" and obtain a lien for unpaid assessments accrued during the previous twelve months.⁵ For condominiums, Section 55-1518 makes an assessment "made in accordance with the declaration, any recorded by-laws, or any duly promulgated project regulation" a debt of the owner and a lien on recording a notice of assessment.² Neither provision caps the size of a special assessment.

Whether a special assessment requires a member vote, and how emergency assessments are handled, turns entirely on what the declaration says. Many Idaho declarations authorize the board to levy special assessments up to a stated dollar amount without a member vote and require approval above it. Emergency provisions, where they exist, are equally creatures of the recorded document. The practical takeaway is consistent: an Idaho board cannot look to a statute for a percentage limit on either regular or special assessments. Authority and limits both come from the declaration and bylaws, with the HOA Act and Condominium Property Act adding disclosure and lien rules on top.

Section 3: Assessment limits and procedures in practice

A. Regular assessment increase procedure

An increase follows whatever process the declaration prescribes. The board adopts the annual budget and sets the assessment as the governing documents direct; where those are silent, the increase requires majority member approval — for HOAs under Idaho Code § 55-3204, and for unincorporated HOAs, a majority vote of all members is a required bylaw term.¹ For condominiums, the budget-and-levy process and any member-approval step come from the declaration and bylaws under the Condominium Property Act; the Act supplies no statutory percentage trigger. Notice and effective date follow the governing documents and, for HOA meetings, the nonprofit-corporation notice rules incorporated by § 55-3204.¹

B. Special assessment procedure

Board action under the declaration authorizes a special assessment. Any member-approval threshold is whatever the declaration sets; no statute imposes one. For HOAs, the Act addresses only the lien for unpaid amounts under Idaho Code § 55-3207, not the approval process.⁵ For condominiums, the special assessment becomes a lien on recording a notice of assessment under Idaho Code § 55-1518, but the levy itself proceeds under the declaration.²

C. Caps, ceilings, and override mechanisms

Idaho provides no statutory percentage cap on regular or special assessments for either community type. Where a cap or ceiling exists, the declaration created it. Idaho has no UCIOA owner-veto over an adopted budget and no statutory reserve-study or reserve-funding mandate.⁶ Any override of a declaration-based limit runs through the amendment process in the declaration itself.

D. Notice, documentation, and disclosure tied to assessments

Assessment-increase notice follows the declaration and bylaws; no statute prescribes a specific notice period for the increase itself. Separately, the Homeowner's Association Act requires an HOA to furnish a member's assessment-account statement within five business days of a written request, an updated financial disclosure within ten business days of a request, and an updated, reconciled financial disclosure to all members within sixty days after the close of the fiscal year.⁴ An HOA may not charge a transfer fee unless the declaration expressly authorizes it, and it must disclose the fees it charges on or before January 1 each year.⁴ The Condominium Property Act contains a separate statement-of-account and fee-disclosure provision at § 55-1528.

Section 4: Recent legislative and judicial activity

A. Recent bills

Idaho's recent legislative activity touches disclosure and governance — not assessment caps. Both bills signed into law since 2024 tighten what associations must tell members and how fast they must do it.

B. Recent appellate rulings

Idaho courts are not rewriting HOA assessment law from the bench. The most significant recent decision applies a principle that should already be familiar: an association can only assess what its declaration authorizes.

C. Active legislative debates

House Bill 708, introduced in the 2026 session by Representative Jeff Ehlers (R-Meridian), would create a new Idaho Code § 55-3204C providing for the automatic dissolution of older associations. The bill did not advance to enactment; it is reportedly being reworked for possible reintroduction. It does not amend the assessment, lien, or disclosure provisions. No Idaho bill in the current period proposes a statutory percentage cap on assessment increases.

Section 5: National positioning and related coverage

Idaho falls in the declaration-driven group of states for assessment limits. That group contrasts with statutory-cap states like California, where Cal. Civ. Code § 5605(b) bars the board from imposing a regular assessment more than 20 percent greater than the prior fiscal year's assessment — or special assessments that, in the aggregate, exceed 5 percent of the association's budgeted gross expenses — without majority-of-quorum member approval. It also contrasts with states that have adopted the Uniform Common Interest Ownership Act with its owner-veto budget mechanism: Alaska, Colorado, Connecticut, Delaware, Vermont, and Washington, where owners can veto a board-adopted budget.

In declaration-driven states — Idaho, Iowa, Alabama, and Arkansas among them — the recorded declaration sets the ceiling and no statutory percentage limit applies. Idaho's 2022 Homeowner's Association Act layers disclosure, lien, and due-process rules on top of that foundation without changing the fundamental structure. For a multi-state operator entering Idaho, the governing documents — not a state cap — determine how far and how fast assessments can move. Document review is the controlling diligence step. Federal frameworks also bear on Idaho assessment practice, including the Fair Debt Collection Practices Act when third-party collectors pursue delinquent assessments, the Servicemembers Civil Relief Act, and the treatment of assessments in bankruptcy.

No current Idaho legislative momentum points toward a statutory assessment cap.
