South Dakota HOA Special Assessment Law: Vote Thresholds and Common Mistakes

South Dakota HOA Special Assessment Law: Vote Thresholds and Common Mistakes

South Dakota has no state statute that caps special assessments or mandates a specific vote threshold for homeowner associations. Your association's governing documents control the procedure, amount limits, and member approval requirements when your board levies a special assessment. This absence of statutory regulation means your bylaws and declaration of covenants are the sole source of authority and restriction.

Because South Dakota law does not prescribe assessment caps or procedures, your first action is to review your governing documents. Check whether your declaration establishes a dollar limit per unit, a percentage cap relative to annual assessments, or a total aggregate limit. Verify whether your bylaws require a board vote, a member vote, or both. Note the quorum and approval threshold. If your documents are silent on special assessments, you face ambiguity that can lead to disputes and litigation.

Common Mistake One: Assuming No Limit Means Unlimited Authority

The most frequent error South Dakota boards make is treating the absence of a state statute as permission to levy any amount without member approval. Your declaration may contain a cap even when state law does not. A typical South Dakota HOA declaration written in the 1990s or 2000s caps annual special assessments at 10 to 25 percent of the prior year's regular assessments without a member vote. Anything above that threshold requires approval by a majority or supermajority of members.

If your board ignores this cap and levies a large assessment without the required vote, unit owners can challenge the assessment in state court. South Dakota courts apply contract principles to HOA governing documents. If your declaration says a vote is required and you skipped the vote, the assessment is unenforceable. You must refund the amounts collected and restart the process correctly.

A concrete example from Rapid City illustrates the risk. In 2019, the Black Hills Ridge Homeowners Association attempted to levy a $150,000 special assessment for road repairs after severe flooding damaged access roads in the summer storm season. The board voted to divide the cost equally among 75 units, resulting in a $2,000 per unit charge. The board believed the emergency nature of the repairs justified skipping the member vote required by the bylaws. Three owners filed a lawsuit in circuit court. The parties settled after the association agreed to hold a member vote and reduce the per unit charge by spreading costs over two years. Legal fees exceeded $18,000.

Common Mistake Two: Inadequate Notice and Documentation

Even when your bylaws do not specify a notice period, South Dakota common law requires reasonable notice before a member vote or board decision that materially affects property rights. Reasonable notice typically means 14 to 30 days in writing, depending on the size of the assessment and the urgency of the situation. If you send notice seven days before a vote on a $100,000 assessment, members can argue they lacked sufficient time to review financial statements, obtain quotes, or consult advisors.

Your notice should include the total amount of the assessment, the per unit allocation, the purpose of the funds, a timeline for collection, and the consequences of non payment. Attach supporting documents such as contractor bids, engineering reports, or reserve study excerpts. If your bylaws require a vote, state the date, time, and location of the meeting, the quorum requirement, and the approval threshold.

Common Mistake Three: Failing to Document the Vote Correctly

When your bylaws require a member vote, you must record the vote in meeting minutes and maintain a tally that shows compliance with the quorum and approval threshold. South Dakota courts review meeting minutes as evidence of corporate action. If your minutes do not reflect the number of votes cast, the percentage of units represented, or the outcome of the vote, you create a gap in the record that undermines enforceability.

Best practice is to create a written ballot for each unit, number the ballots, tally the results in front of witnesses, and record the tally in the minutes. If you allow proxy votes, verify that each proxy is signed, dated, and filed before the meeting. Store the ballots and proxies with your permanent records. If a dispute arises two years later, you will need this documentation to prove the vote was valid.

What South Dakota Law Does Require

Although South Dakota has no special assessment statute, your board owes fiduciary duties to members under common law. You must act in good faith, exercise reasonable care, and prioritize the association's interests over personal interests. If your board levies a special assessment to benefit a board member's business or to fund a project that provides no community benefit, members can sue for breach of fiduciary duty in circuit court.

The South Dakota Attorney General's office has limited authority over HOAs. The office can investigate consumer fraud if an association engages in deceptive practices, but it does not regulate special assessments or enforce governing documents. Your recourse for assessment disputes is state circuit court, where contract and corporate law principles apply.

State Specific Context: Weather and Infrastructure Challenges

South Dakota's climate creates recurring infrastructure costs that often trigger special assessments. Winter temperatures regularly drop below zero across the state, causing freeze thaw cycles that damage roads, sidewalks, and building foundations. Spring snowmelt and summer thunderstorms produce localized flooding, particularly in associations near streams or low elevation areas. Boards in South Dakota should budget conservatively for infrastructure repairs and maintain adequate reserves to avoid large emergency assessments.

What You Should Do Now

Pull your declaration and bylaws. Identify any language that mentions special assessments, extraordinary expenses, or emergency funding. Note the approval threshold, notice requirements, and any dollar caps. If your documents are silent, consider amending them to establish a clear process. Draft a resolution that documents the board's authority to levy assessments up to a specific amount without a vote and requires a vote above that threshold.

If you are planning a special assessment in the next 12 months, prepare a budget worksheet that shows the total cost, per unit allocation, payment schedule, and funding purpose. Obtain at least three bids for any project over $10,000. Schedule a member meeting at least 30 days in advance and send written notice that includes all supporting documents. Consult your attorney for your specific situation to confirm that your proposed process matches your governing documents and meets South Dakota common law standards.
