The association’s money
What is an HOA reserve study — and does Minnesota require one?
Reviewed August 2026 · Elevate Community Management
The short answer
A reserve study is an inventory of everything the association must eventually replace — roofs, siding, asphalt, mechanicals — with each component’s remaining life and cost, converted into a funding plan. Minnesota law (Minn. Stat. § 515B.3-1141) requires budgets to include adequate replacement reserves, held separately and reevaluated at least every three years.
What a reserve study contains
A reserve study has two halves. The physical analysis inventories the common components the association is obligated to maintain — roofs, siding, decks, asphalt, concrete, retaining walls, irrigation, pool equipment, building mechanicals — and estimates each one’s remaining useful life and replacement cost. The financial analysis converts that inventory into a funding plan: what the association should contribute each year so the money exists when each component reaches the end of its life.
The headline metric is percent funded — actual reserve balance versus the deterioration the components have already accrued. As a rule of thumb, above ~70% funded is strong, while communities under ~30% are the ones where special assessments and loans happen. The number matters less than the trajectory: a 45%-funded association on a real plan is healthier than a 60%-funded one drifting downward.
What Minnesota law actually requires
Minnesota is more specific than most states. Under Minn. Stat. § 515B.3-1141, an association’s annual budget must include replacement reserves projected by the board to be adequate for the components it must maintain; the reserves must be kept separate from operating funds; adequacy must be reevaluated at least every three years; and replacement reserves may not be used for operating expenses.
Notice what the statute does: it makes "we’ll deal with the roof when we get there" a compliance failure, not a budgeting style. It also gives boards a clean answer to the owner who asks why assessments fund a roof fifteen years out — because deterioration accrues every year, and the law expects each year’s owners to pay their share of it. The board’s duty of care (explained here) points the same direction.
Why Minnesota is hard on components
Freeze-thaw cycling is a component-killer: asphalt heaves and cracks, concrete spalls, ice dams work shingles loose, and irrigation systems that are not winterized correctly die young. Snow-removal equipment and contracts also scrape the same asphalt the reserve schedule is trying to protect. A reserve study built on national averages quietly flatters a Minnesota community — useful lives here run shorter for anything water touches.
This is where a management company with construction judgment earns its fee: knowing whether the study’s "12 years remaining" on the siding matches what the siding actually says, sequencing projects so mobilization costs are shared, and supervising the eventual replacement so the association gets the life it paid for.
Underfunded? The way out is boring and it works
An underfunded association has exactly four levers: raise regular assessments, add a dedicated reserve line, special-assess, or borrow. The credible plans use the first two early and small instead of the last two late and large. A 10% assessment increase adopted this budget season is what prevents the $8,000-per-unit special assessment in year seven — the arithmetic is unforgiving and it does not negotiate.
The board’s job is to pick a trajectory and hold it; the manager’s job is to keep the plan visible — reserve balance and funding progress on every monthly statement, not rediscovered every three years. If your last "reserve plan" was a line item somebody copied forward, we should talk.
Questions boards ask
How often should a reserve study be updated?
Minnesota requires reserve adequacy to be reevaluated at least every three years, and that cadence matches industry practice: a full study with site inspection periodically, with updates in between. Update sooner after major projects, storm damage, or sharp cost inflation.
Who performs a reserve study?
Independent reserve specialists and engineering firms prepare formal studies; credentialed reserve specialists (RS/PRA designations) are the usual choice for larger communities. Small associations sometimes start with a professionally guided component inventory and graduate to a full study.
Can reserves be used to cover an operating shortfall?
Not in Minnesota — the statute prohibits applying replacement reserves to operating expenses. An operating gap has to be fixed in the operating budget; papering it over with reserve cash is both unlawful and the fastest route to a special assessment later.
What percent funded should our reserves be?
Higher is safer, but trajectory beats snapshot. Above roughly 70% funded, special-assessment risk is low; below 30% it is high. What matters is a funding plan that climbs — and a board that adopts the assessment level the plan requires.
