Arizona Reserve Study Requirements: ARS Title 33 in Practice

Arizona Reserve Study Requirements: ARS Title 33 in Practice

Arizona governs HOA and condo reserves through Arizona Revised Statutes Title 33, with the Planned Communities Act at Chapter 16 and the Condominium Act at Chapter 9. Neither chapter mandates a reserve study, and ARS 33-1812 frames reserve language as a governing document obligation rather than a state mandate. That puts the discipline back on your board and the documents your developer filed.

What ARS Title 33 actually requires

ARS 33-1804 sets open meeting rules. ARS 33-1810 sets fiduciary duties. ARS 33-1812 references reserve fund expenditures within budgetary discipline but does not impose a specific study cadence or funding percentage. The Arizona Department of Real Estate, known as ADRE, oversees community management licensing and subdivision developer disclosures, but ADRE does not police HOA reserve studies once a community is past developer turnover.

The result: your CCRs are the only document with binding reserve language for most Arizona communities.

Where your governing documents probably do require reserves

Arizona master deeds typically include three reserve touch points. The covenants section sets the right to assess for reserves. The bylaws set the board duty to budget. The maintenance section lists components the association must maintain, which becomes your reserve inventory.

If you have not read these passages in the past 12 months, your real reserve obligation is unknown to you. The Arizona Attorney General consumer protection division receives recurring HOA complaints tied to surprise special assessments, and the common thread is a board that did not know what its own documents required.

What good Arizona practice looks like

Five practices distinguish Arizona boards that handle reserves well.

1. Commission a reserve study every 5 years even though state law does not require one. Three years is better in fast growing communities.
2. Treat the reserve account as restricted. Co mingling reserves with operating funds is the most common board mistake in Arizona.
3. Disclose reserve status in the annual budget package, not just on request. Arizona open meeting law expects substantive transparency.
4. Track the homeowner relief fund deadline cycle separately. Arizona has tightened restrictions on transfer fees and surcharges in recent sessions, and reserve practices should not depend on those revenues.
5. Coordinate with the Arizona Department of Real Estate during developer turnover. The turnover audit is the cheapest reserve baseline you will ever get.

Recent Arizona developments

Two threads matter for 2026 boards.

ARS 33-1818 limits HOA enforcement powers and has been amended several sessions in a row. Boards reading the statute for the first time should check the version current at the time of any enforcement decision tied to a reserve funded improvement.

The CAI Arizona chapter, known as CAI AZ, runs the most current legislative tracker for community association bills. The chapter publishes a session recap each summer that names the bills boards should adjust budgets and reserves around. Subscribe to the chapter newsletter or check caiaz.org for the latest cycle.

The most common Arizona reserve mistakes

Three patterns surface most often.

First, boards treat the absence of a state mandate as the absence of duty. The Planned Communities Act expects fiduciary care, and a missed reserve study can support a claim of neglect.

Second, transfer fees and capital contributions get treated as reserve income. Arizona has narrowed what those fees can fund. Boards that built reserves around them are exposed.

Third, developer reserve transfer at turnover gets accepted without a study. The owner controlled board often inherits an underfunded reserve and discovers the gap years later, when the first major repair lands.

What your board should do this quarter

Take four actions.

1. Locate the reserve language in your CCRs and bylaws and read it carefully.
2. If your last reserve study is older than 5 years, contract a new one.
3. Confirm your operating and reserve accounts are physically separate at the bank.
4. Pull the most recent CAI Arizona legislative recap to confirm no 2025 or 2026 amendment changed your obligations.
