Identify which approval model applies
Special-assessment approval falls into one of a few models, and the association's statute and governing documents decide which: a board threshold model (the board may levy up to a cap, above which a member vote is required); an affirmative owner-vote model (a defined percentage of owners must approve); a ratification or rejection model (the board levies, but owners can call a meeting and reject or replace it); or a document-driven model where the declaration sets the rule. California is one board-threshold example — without a member vote a board may levy a special assessment up to 5 percent of the association's budgeted gross expenses for the fiscal year, with amounts above that needing approval by a majority of a quorum (California Civil Code §§5605 and 5615 — a California example, not a national rule). A board that assumes it can approve any dollar amount on its own authority is one of the more common ways a special assessment ends up overturned.
Running the membership vote correctly
Where a membership vote applies, store four things separately, each verified against the controlling source: the quorum or participation requirement, the approval denominator (majority of a quorum, majority of all members, or a supermajority), the voting method (secret ballot is frequently required), and the notice timing, delivery, and content. A board that gets quorum right but uses the wrong voting method has still created a procedural defect a court may treat as fatal to the assessment's validity.
Confirm the board-only assessment threshold under state law and governing documents → confirm the required quorum, approval margin, and voting method if a membership vote is needed → draft notice content matching the statutory requirements → send notice within the required window → keep a full audit trail of ballots and the certified result.
What the written notice has to say
A compliant special-assessment notice generally states the amount owed per unit, the specific reason for the assessment, the due date or payment schedule, and — critically — the specific governing-document or statutory provision that authorizes the charge. Many states also require the notice to go out within a defined window before the first payment is due, often 30 to 60 days, delivered by a specific method such as first-class or certified mail or an approved electronic method the owner has consented to. A notice that states only the amount and due date without identifying the authorizing provision or vote result is a common, avoidable gap.
The audit trail is what survives a challenge
Procedural errors — insufficient notice, an incorrect quorum calculation, or a missing paper trail for the vote — are the most commonly cited reasons special assessments get overturned after the fact. The board should retain the resolution or ballot language, the certified vote count, proof of when and how notice was sent, and the specific budget or reserve-study data that supported the amount requested. This record matters most exactly when it's least convenient to produce — months or years after the vote, when a challenge surfaces.
What a complete special-assessment file should contain
- The board resolution or ballot proposal with the exact amount and stated purpose.
- Confirmation of whether board-only authority or a membership vote applied, and why.
- The certified vote count if a membership vote was required.
- Proof of the notice sent to owners, including date and delivery method.
- The underlying reserve study, bid, or budget data supporting the requested amount.
Checking the notice language before it goes out
An association attorney should review the notice language and vote procedure before a large or controversial special assessment goes out, since a successful procedural challenge can force the association to rescind and re-run the entire process — losing months of time on a capital project that may already be urgent.

Frequently asked questions
- Does every HOA special assessment require a member vote?
- No. The declaration or state statute may let the board levy some special assessments up to a threshold while requiring owner approval above it, and emergency exceptions may follow a different route. The board should determine the approval path before sending a payment notice.
- What should the notice of a special assessment tell owners?
- A complete notice typically identifies the amount, purpose, allocation method, due dates or installments, and the authority under which the assessment was approved. State law or the governing documents may also require advance meeting notice, voting materials, or a separate post-approval notice.
- Can an HOA special assessment be challenged because the allocation is wrong?
- Yes. Even when the project and total amount are authorized, the association must allocate the expense according to the declaration and applicable law. The board should verify each unit or lot's common-expense share before issuing the ledger charges.
