How is a siding special assessment calculated?
The assessment is project cost minus available reserves, allocated by multiplying the remaining funding need by each unit’s applicable expense interest — using the governing documents’ expense allocation, which is not automatically the voting percentage. An owner with a larger allocated interest pays a larger share, and every dollar of reserves directly lowers everyone’s number.
| Step | Figure |
|---|---|
| 1. Total project cost (scoped) | A |
| 2. Less reserves applied | − B |
| 3. Amount to assess | = A − B |
| 4. Each owner’s share | (A − B) × that unit’s allocated interest |
One Missouri wrinkle: where exterior walls or siding are designated limited common elements — as they often are — the cost may be allocated only to the units they benefit, to the extent the declaration requires (RSMo § 448.3-115). That can change who pays. The single most important input is a real, scoped project cost rather than a ballpark; an assessment built on a scoped, line-item bid is much easier to put in front of owners. See per-unit cost of re-siding.
How does a Kansas association levy one?
Kansas gives boards clear, statute-based authority. Under the Kansas Uniform Common Interest Owners Bill of Rights Act (KUCIOROBRA, effective January 1, 2011), a board “at any time, may propose a special assessment” using the same procedure it uses for the annual budget: 10-day advance notice and an owner-comment opportunity, with no ratification vote required for an ordinary assessment. An emergency assessment takes a two-thirds board vote and is restricted to its stated purpose. There’s no statutory dollar cap (K.S.A. 58-4620).
The practical sequence for a Kansas siding assessment:
- Scope and price the project so the amount is real, not a guess.
- Give 10-day advance notice of the proposed assessment to owners.
- Hold the owner-comment opportunity the statute calls for.
- Adopt it — ordinary: no ratification vote; emergency: two-thirds board vote, stated purpose only.
- Apply reserves first to keep the per-owner number down.
The notice-and-comment step is the one boards most often overlook. The authority to assess is clearly there; the procedure is just worth following exactly. One more Kansas detail worth knowing: KUCIOROBRA’s provisions are mandatory and can’t be waived by the declaration (K.S.A. 58-4603), so the declaration can add conditions but can’t override the act’s core rules.
How does a Missouri association levy one?
Missouri runs more through your governing documents than through statute. The Missouri Uniform Condominium Act (RSMo Ch. 448) sets the framework for condominiums created after September 28, 1983, but it leaves the special-assessment procedure, any cap, and any owner-approval threshold to your recorded declaration. There’s no statewide dollar cap and no mandatory owner-vote supermajority in the statute — those, if they exist for your community, are in the declaration. (Many non-condo townhome and single-family HOAs are governed by their CC&Rs plus the Missouri Nonprofit Corporation Act, RSMo Ch. 355, instead.)
So the practical first move for a Missouri board is to pull and read the declaration before sizing the assessment: it’s where the procedure, any cap, and any vote threshold actually live. On siding specifically, check whether the declaration treats exterior walls as limited common elements, since that affects which units bear the cost.
Here’s the contrast between the two states at a glance:
| Feature | Kansas (KUCIOROBRA) | Missouri (RSMo Ch. 448) |
|---|---|---|
| Reserve mandate | No | No |
| Special-assessment authority | Board may propose with 10-day notice | Per declaration |
| Owner ratification vote | Not required for an ordinary assessment | Per declaration |
| Emergency assessment | Two-thirds board vote | Per declaration |
| Statutory dollar cap | None | None |
| Where the rules live | The statute (mandatory) | The recorded declaration |
How big is a typical siding special assessment?
There’s no reliable “typical” number, and any page that hands you one as a hard fact is guessing. The figure is whatever the project funding need after available reserves, multiplied by the applicable expense interest, works out to — and that swings with material, building height and access, hidden rot, hail damage, and how much of the cost reserves absorb. A reserves-rich association re-siding a low-rise in vinyl lands well below a thin-reserves KC association swapping failed stucco or hail-shredded vinyl for fiber cement on a taller building.
| Scenario | Project cost | Reserves applied | Per-unit result |
|---|---|---|---|
| Vinyl re-side, strong reserves, low-rise | lower | high | toward the low end |
| Fiber cement, thin reserves, hidden rot + hail, taller building | higher | low | well above |
(Illustrative scenarios, not an actual project.) For the per-square-foot and per-unit inputs that drive these, see per-unit cost of re-siding.
How do you help a large assessment pass?
You make it smaller and less of a surprise. Apply reserves to lower the number, offer an installment plan or pair the assessment with a loan so no owner faces an impossible one-time payment, bring a real scoped cost instead of a guess, follow your state’s procedure exactly, and consider phasing so the ask is smaller now. Owners approve assessments they understand and can manage.
The levers, in rough order of impact:
- Apply reserves first — every dollar of reserves is a dollar less assessed.
- Offer installments or a loan — convert a lump sum into payments. See how associations pay for siding.
- Bring a scoped, comparable cost — a line-item bid is far easier to defend than a round number.
- Phase the work — split the project across budget years.
- Follow the procedure — Kansas: 10-day notice and comment. Missouri: your declaration’s thresholds.
- Explain the why early — hail, visible failure, code, thin reserves — before the meeting.
A board that walks in with the reserve math, a real bid scope, a payment option, and clean procedure has a much easier time than one presenting a bare lump-sum number.
