Arizona HOA Quorum & Supermajority Calculator — ARS 33-1804 + 33-1817 (25% Quorum Default; 67% Amendment Default; Absentee Ballots)

How this calculator works

This is a quorum-and-threshold validator for Arizona HOA member votes under the Arizona Planned Communities Act. Given the total members, in-person attendance, proxy count, absentee-ballot count, vote type, and any declaration-specified overrides, it returns:

1. Whether quorum has been met (total ballots compared against the effective quorum requirement under ARS 33-1804(A) declaration specification, or the 25% customary Arizona default when the declaration is silent).
2. The yes votes required to pass for the vote type — 67% of total voting power for declaration amendments under ARS 33-1817(A), majority of total for board removal under ARS 33-1804(B), majority of total for special-assessment ratification, unanimous for termination, and majority of quorum for regular votes and bylaws amendments when bylaws are silent.
3. The current outcome (PASSED, FAILED, PENDING, or NO-QUORUM) based on the supplied vote tally.

Use the calculator before convening a member meeting to confirm the procedural framework, during ballot counting to validate the threshold, and after a meeting to memorialize the outcome in the secretary minutes. The calculator counts absentee ballots toward quorum separately from in-person attendance and proxies, reflecting the Arizona statutory mechanism under ARS 33-1804.

The relevant ARS Title 33 statute

The Arizona Planned Communities Act lives at ARS Title 33 Chapter 16. Voting and quorum provisions are concentrated in ARS 33-1804 (open meeting requirements; member meeting procedures), ARS 33-1804.01 (board meeting procedures), and ARS 33-1817 (declaration amendment).

ARS 33-1804(A) — open meeting and quorum. The Act refers quorum to the declaration or bylaws. When neither specifies, the customary Arizona default is 25 percent of the membership — materially lower than the 51% non-profit default in other states. The 25% default reflects Arizona policy favoring active governance and absentee-ballot facilitation. Many Arizona declarations explicitly specify 25% or 33%.

ARS 33-1804 — absentee ballots permitted. Arizona uniquely permits absentee ballots alongside proxies. Absentee ballots typically circulate in advance of the meeting with the meeting notice, state the proposed measure in identical language to the meeting agenda, provide YES / NO / ABSTAIN options, include a signature and return-by deadline, and count once for quorum and once for the tally.

ARS 33-1804(B) — board removal. Board member removal requires a majority of the votes in the association — an OF-TOTAL threshold, NOT a majority-of-those-present. This is materially stricter than the standard in many other states.

ARS 33-1817(A) — declaration amendment. Declaration amendments require a majority of the votes in the association unless the declaration specifies a larger percentage. The customary default referenced in Arizona practitioner materials is 67 percent (two-thirds) of the total voting power. This is a TOTAL-VOTING-POWER threshold (not OF-VOTERS). The declaration may specify higher (75% or 80%); it cannot specify lower than the statutory floor.

ARS 33-1817 special amendments. Certain declaration amendments require a higher threshold or UNANIMOUS consent: changes to allocated interests, unit boundaries, dedications of common areas, and rental restrictions. These are the highest-threshold actions under the Act.

ARS 33-1804.01 — board meetings. Board meetings have separate procedural requirements (notice, agenda, open-to-members standards). The calculator does not model board meeting procedures.

ARS Title 10 — non-profit corporation law. Supplies gap-filler procedures for governance matters not addressed in Title 33.

Arizona-specific gotchas (NO super-priority, 1-year/$1,200 foreclosure prerequisites, judicial-only)

ARIZONA DOES NOT FORMALLY LICENSE COMMUNITY MANAGERS — BUT REGISTRATION IS REQUIRED. Unlike Florida (Fla. Stat. 468.431 LCAM licensure), Nevada (NRS 116A CAM licensure), and Washington DC (DLCP CICM licensure), Arizona has NO state-level licensure requirement for community association managers. ARS 32-2199 requires fee-based community managers to REGISTER with the Arizona Department of Real Estate (ADRE), but the registration does not involve the broker-style examination or continuing-education requirement. Practical consequence: Arizona HOA boards bear primary responsibility for governance compliance and the calculator (with statute citations) is intended as a tool the board or an ADRE-registered manager can use directly.

THE 67% DECLARATION-AMENDMENT THRESHOLD IS OF-TOTAL, NOT OF-VOTERS. This is the most common voting-threshold error in Arizona HOA practice. The 67% under ARS 33-1817(A) applies to TOTAL voting power, not to votes cast. In a 200-lot association with 130 voters returning ballots (65% turnout), 100 yes votes (77% of voters) is only 50% of total — well short of the 134-vote threshold and the amendment FAILS. Boards routinely announce declaration amendments as passed based on majority-of-voters math; this is wrong. The calculator distinguishes the two thresholds explicitly to prevent the error.

BOARD REMOVAL ALSO USES OF-TOTAL. ARS 33-1804(B) requires board member removal by a majority of votes in the association — also OF-TOTAL. This is materially stricter than the standard in Ohio (majority of those present at a quorum meeting), Florida, or Washington. In a 200-lot Arizona association, board removal requires 101 yes votes regardless of attendance. Combined with the absentee-ballot mechanism, board-removal campaigns are logistically intensive but procedurally feasible.

ABSENTEE BALLOTS ARE THE KEY MECHANISM FOR REACHING OF-TOTAL THRESHOLDS. Arizona uniquely permits absentee ballots alongside proxies under ARS 33-1804. The absentee-ballot mechanism is widely used in Arizona to reach quorum and threshold for high-turnout votes (declaration amendments, board removal, special assessments). Practical guidance: send absentee ballots with the meeting notice for any consequential vote; absentee ballots count once for quorum and once for the tally, materially expanding the reachable yes-vote pool beyond meeting attendees.

THE 25% QUORUM DEFAULT IS LOWER THAN OTHER STATES. The customary 25% Arizona default for quorum is lower than the 51% non-profit gap-filler used in Ohio and many other states. This reflects Arizona policy favoring active governance — but it also means a small minority can transact business at a regular meeting (subject to the OF-TOTAL threshold for consequential votes, which neutralizes the low quorum). Always check the actual declaration for the quorum specification, because the gap-filler default applies only when both declaration and bylaws are silent.

TERMINATION TYPICALLY REQUIRES UNANIMOUS CONSENT. Termination of an Arizona planned community typically requires UNANIMOUS consent of the owners absent declaration specification of a lower threshold. The unanimous-consent default reflects Arizona policy treating termination as a property-rights matter rather than a majority-rule governance matter. The calculator treats termination as 100% by default but exposes the declaration-specified threshold input for the rare case where the declaration permits a lower threshold (some declarations permit 80% termination).

SPECIAL ASSESSMENTS COMMONLY REQUIRE RATIFICATION. Most Arizona declarations specify that special assessments above a threshold dollar amount or above a percentage of the annual budget require ratification by a majority of votes in the association — an OF-TOTAL threshold. The calculator treats special-assessment ratification as 51% of-total by default; check the actual declaration for the specific threshold and ratification procedure.

PROXIES ARE COMMON BUT MUST BE CURRENT. Arizona bylaws commonly permit proxies for member voting; the calculator counts proxies once for quorum and once for the tally. Many Arizona bylaws specify maximum proxy validity periods (commonly 11 months). Proxies older than the period are invalid even if all other elements are met. For OF-TOTAL threshold votes, combining proxies and absentee ballots is typically necessary to reach the threshold.

What this calculator does NOT model

The calculator implements the Arizona QUORUM-AND-SUPERMAJORITY math. It does NOT:

• Model the heightened-threshold and unanimous-consent categories under ARS 33-1817 (changes to allocated interests, unit boundaries, dedications of common areas, rental restrictions). If your vote type falls into one of these categories, the 67% threshold understates the requirement; consult counsel.
• Model the ARS 33-1804.01 board meeting procedures in detail (board meetings have separate quorum and notice requirements typically specified in the bylaws).
• Validate the form of proxies (signature, witness, expiration, delegation chain).
• Validate the form of absentee ballots (required content, return-by deadline, signature verification).
• Model the open-meeting and notice requirements under ARS 33-1804 that gate the meeting (improperly noticed meetings cannot transact business regardless of quorum).
• Model the parallel ARS 32-2199 ADRE dispute resolution process for non-collection governance disputes.
• Account for weighted-voting allocations when the declaration allocates votes by lot acreage, improvement value, or other non-uniform basis rather than one-vote-per-lot.

For any consequential vote, retain Arizona counsel with ARS Title 33 Chapter 16 experience to oversee the procedural compliance review.
