HOA Reserve Fund Compliance in Michigan: What Volunteer Boards Need to Know

Last updated: March 21, 2026

TLDR

Michigan condominiums are governed by MCL 559.101, which requires boards to maintain adequate reserve funds. Volunteer boards that commingle operating and reserve funds or fail to fund reserves risk personal liability for breach of fiduciary duty.

Michigan’s condominium law (MCL 559.101 et seq.) places real obligations on volunteer boards. MCL 559.157 requires associations to hold reserve funds in a separate, dedicated account and restrict their use to capital expenditures and deferred maintenance. Boards that treat reserves as a buffer for operating overruns expose themselves to personal liability under the fiduciary duty standard in MCL 559.152. Michigan courts do not give volunteer boards a pass because they were unpaid — the duty of care applies regardless.

The Detroit metro area alone has thousands of condominium associations, many with aging common elements: parking structures, elevators, roofs, and HVAC systems representing substantial capital expenditures. Grand Rapids and Lansing are adding new associations through suburban development, but new construction does not eliminate the reserve obligation. Reserves must be funded from day one. Boards that inherit underfunded reserves from a developer transition face a difficult situation, and commissioning a reserve study early is the most important corrective step they can take.

BoardStack was built for volunteer treasurers managing real statutory obligations without a staff accountant or dedicated compliance officer. The platform separates operating and reserve accounts at the software level, making commingling structurally difficult, and tracks reserve fund balances alongside the capital items that depend on them. Michigan boards use it to document their reserve funding rationale — the foundation of any good-faith fiduciary defense.

Reserve Account Requirement (MCL 559.157)

Michigan condominium associations must establish and maintain a reserve fund separate from the operating account. MCL 559.157 requires that reserve funds be held in a dedicated account and used only for capital expenditures and deferred maintenance — not for routine operating expenses.

Reserve Study Requirement

Michigan does not mandate a formal reserve study by statute, but MCL 559.157 requires the board to assess the long-term capital needs of common elements. Courts have interpreted the fiduciary duty standard under MCL 559.152 to require boards to have a reasonable basis for reserve funding levels — effectively making a periodic study a best practice that boards should document.

Annual Budget and Disclosure (MCL 559.169)

Michigan condo boards must prepare an annual budget and distribute it to all co-owners at least 10 days before adoption. The budget must include both operating expenses and reserve contributions. Boards that skip this step expose themselves to challenges from unit owners.

Board Liability Safe Harbor

Michigan courts apply the business judgment rule to HOA board decisions. Boards that act in good faith, document their reserve funding rationale, and engage professional assessments substantially reduce their exposure to personal liability claims from unit owners.

Michigan has approximately 17,000 community associations statewide, according to the Foundation for Community Association Research.

What does Michigan law require for HOA reserve funds?

MCL 559.157 requires Michigan condominium associations to maintain a reserve fund in a dedicated account, separate from operating funds. The reserve must be used only for capital expenditures and deferred maintenance on common elements. Homeowners associations that are not condominiums are governed by general nonprofit law and their governing documents, but fiduciary duty principles still require boards to plan for long-term capital needs.

Are Michigan HOA boards personally liable for reserve fund failures?

Volunteer board members can face personal liability for breach of fiduciary duty if they fail to maintain adequate reserves and a unit owner suffers harm as a result — such as a large unexpected special assessment or a decline in property value attributable to deferred maintenance. The business judgment rule provides some protection, but only when boards document their decision-making and act in good faith.

Does Michigan law require a professional reserve study for condo associations?
MCL 559.157 does not explicitly require a third-party reserve study, but the fiduciary duty standard under MCL 559.152 requires boards to have a reasonable, documented basis for reserve contributions. Engaging a reserve specialist is the most defensible way to meet this standard.
Can a Michigan condo board borrow from reserves to cover operating shortfalls?
No. MCL 559.157 requires reserve funds to be segregated and used exclusively for capital expenditures and deferred maintenance. Using reserve funds for operating expenses — even as a short-term loan — is a breach of fiduciary duty and potentially a violation of the Act.
What happens if a Michigan HOA fails to maintain adequate reserves?
Inadequate reserves can lead to special assessments on unit owners, which are unpopular and legally challengeable. Boards may also face personal liability claims if a co-owner can show that underfunding was the result of negligence or self-dealing.
