TLDR
Arizona is one of the stricter states for HOA financial governance. Condominium associations must conduct reserve studies under ARS §33-1256, and planned communities face budget and financial disclosure obligations under ARS §33-1803. Boards that fail to fund reserves adequately or that commingle operating and reserve funds face statutory noncompliance and personal liability exposure.
Arizona’s HOA statutes are among the more detailed in the Sun Belt. Rapid population growth has produced thousands of new planned communities and condominium associations, most of them self-managed by volunteer boards who did not anticipate the compliance obligations they inherited. Boards need to know whether condominium law (ARS §33-1201 et seq.) or planned community law (ARS §33-1801 et seq.) governs their association before assessing their obligations.
For condominium boards, the reserve study requirement under ARS §33-1256 is the most consequential obligation. A reserve study is not a one-time exercise, boards must update it periodically as component conditions change and costs evolve. BoardStack helps volunteer treasurers track reserve fund balances against study projections, flag when contributions fall behind plan, and generate the documentation a board needs to show it acted in accordance with the study’s recommendations.
Planned community boards in Arizona face a different primary risk: budget ratification. ARS §33-1803 requires the board to present an annual budget, including planned reserve contributions, to the membership for ratification. Boards that adopt budgets without a ratification meeting, or that omit reserve contributions entirely, are in technical violation of the statute. Separate, labeled accounts for operating and reserve funds are the foundation of compliant governance for Arizona HOA boards.
Condo Reserve Study Requirement (ARS §33-1256)
Arizona condominium associations are required to maintain a reserve fund and conduct a periodic reserve study. The study must assess the current and projected condition of major common elements and estimate the funding needed to repair or replace them. Boards that knowingly underfund reserves after a study has identified deficiencies face heightened fiduciary liability.
Planned Community Budget Disclosure (ARS §33-1803)
Planned community associations must prepare an annual budget and distribute it to members before the start of each fiscal year. The budget must include planned reserve contributions. Members have the right to ratify or reject the budget, and associations must hold a meeting for that purpose.
Financial Records Inspection Rights (ARS §33-1258 / §33-1805)
Both condo and planned community statutes grant members the right to inspect financial records including bank statements, invoices, and reserve account statements. Records must be made available within ten business days of a written request. Boards that maintain records only in personal spreadsheets or email inboxes risk noncompliance.
No Statewide Reserve Study Mandate for HOAs
Arizona imposes no statewide reserve study or funding mandate for planned community HOAs (ARS §33-1801 et seq.), despite approximately 82% of new homes in Mountain West states being built in HOA communities. Arizona has one of the highest HOA prevalence rates in the country with no corresponding state reserve mandate for planned communities.
Reserve Fund Segregation
Arizona statutes imply, and standard governance practice requires, that reserve funds be kept in a separate account from operating funds. The Arizona Department of Real Estate has issued guidance advising condominium associations to maintain distinct reserve accounts. Commingling is a recognized indicator of fiduciary breach in Arizona HOA disputes.
Fannie Mae Reserve Allocation Requirement
Fannie Mae Lender Letter LL-2026-03 sets two deadlines: (1) The Limited Review process for condo projects is retired effective August 3, 2026. (2) The minimum reserve allocation increases from 10% to 15% for Full Review loan applications dated on or after January 4, 2027. Associations below the 15% threshold will be classified as non-warrantable, preventing conventional mortgage lending on units in the community.

| Scottsdale | ~1,200+ | Reserve funding adequacy, records access |
| Tucson | ~1,800+ | Budget disclosure, deferred maintenance |
| Mesa / Chandler / Gilbert | ~1,300+ | Rapid growth, governing document gaps |
Q&A
Does Arizona require HOA boards to fund a reserve account?
Yes, for condominium associations. ARS §33-1256 requires Arizona condo associations to maintain a reserve fund. Planned communities are not explicitly required by statute to fund reserves, but the budget disclosure requirements under ARS §33-1803 and the board's fiduciary duty make reserve contributions a standard of care expectation.
Q&A
Can Arizona HOA board members be personally sued for reserve fund mismanagement?
Yes. Arizona courts apply a fiduciary duty standard to HOA board members. If a board knowingly underfunds reserves after a reserve study has identified deficiencies, or commingles operating and reserve funds, individual board members can face personal liability claims from unit owners or the association itself.
