What the law actually requires (the light version)
You don’t need to be a statute expert to run this check. The practical takeaways from Minn. Stat. § 515B.3-1141:
- Budget reserves adequate to replace common-element components by the end of their useful life.
- Keep reserve money in a separate account — not the operating fund.
- Reevaluate reserve adequacy at least every third year.
That’s the spine of it. Notably, the statute does not require any particular percent-funded figure — adequacy is defined by function, not by a number. The percent-funded bands above are reserve-study practice layered on top of the legal floor. For the full walkthrough of how a study applies all this to siding, the reserve-study guide is the place to go.
Turning the gut-check into a number
If the gut-check leaves you uneasy, the next move isn’t to guess a dollar figure — it’s to get a reserve study (or update a stale one) that prices your specific siding and sets a contribution that closes the gap on time. A study turns “we think we’re behind” into “we need $X per unit per year for the next seven years.” That’s the number a board can actually act on.
FAQ
How much should we have in our siding reserve? There’s no fixed figure — it depends on your siding type, replacement cost, and remaining life. Run the percent-funded gut-check above; a reserve study turns it into a specific per-unit number.
What percent funded is “safe”? Reserve-study practice commonly treats 70%+ as strong and under 30% as weak and assessment-prone, with the middle band workable on a realistic plan. These are industry rules of thumb, not legal thresholds.
Does Minnesota law set a required reserve amount? No. Minn. Stat. § 515B.3-1141 defines adequacy by function — funding replacement by useful life — and requires a separate account and reevaluation at least every third year. It does not mandate a percentage.
How often should we recheck the number? At least every three years to meet the statute, though many boards align it with their reserve-study update cycle. Run the informal gut-check yearly.
We’re clearly underfunded — now what? Don’t panic-assess. Get or update a reserve study, set a contribution that closes the gap before the siding fails, and document the plan. A credible trajectory is what protects the board.
One note for boards: § 515B.3-1141 was amended in 2026 — confirm the current text before relying on specific provisions.
