If you own a condominium unit, MCL § 559.147(1) draws a clean line. Inside your unit, you can make improvements or alterations that don't impair the structural integrity of the building or lessen the support of any part of the project, and that's a hard statutory floor no condo document can override. Outside your unit, the rule flips: a co-owner "shall not do anything which would change the exterior appearance of a condominium unit or of any other portion of the condominium project except to the extent and subject to the conditions as the condominium documents may specify." In plain terms, exterior control isn't something the statute grants the association independently; it's whatever your master deed and bylaws say it is, and the statute just enforces that bargain either way.
Section 559.147(2) also lets you combine adjoining units, removing an intervening partition or cutting doorways through it, as long as you don't weaken a bearing wall or column or damage another common element, and that kind of connection isn't treated as changing your unit's legal boundaries.
Subdivision HOAs: architectural review is 100% contract, with no protected categories
If you're in an ordinary subdivision HOA, nothing in the Nonprofit Corporation Act touches architectural review, exterior modifications, or any protected use at all. Unlike some states that carve solar panels, flags, or EV chargers out of a board's control by statute, Michigan's condo and nonprofit corporation statutes do neither. That means whatever architectural power your board has, and whatever exception you might win, rests entirely on what your declaration actually says. If your declaration is silent or vague, you're arguing contract interpretation against your neighbors and your board, not a statutory override the legislature already gave you.
The authority
The statutes behind this
Cited by name as authority, for your own reading. Informational only, not legal advice.
MCL 559.147
Lets a co-owner alter the interior of a unit so long as structural integrity and support aren't impaired, but ties any change to the unit's exterior appearance entirely to what the condo documents specify.
MCL 559.154
Lists what condo bylaws must mandatorily address, records, financial statements, vote allocation, arbitration, none of which includes architectural review, underscoring that exterior control is left to the documents rather than the statute.
MCL 450.2501
Gives the board authority over corporate affairs except as the articles otherwise provide, the same corporate-law anchor that leaves architectural control to a subdivision HOA's own documents entirely.
Step by step
How to appeal an architectural denial in Michigan
Steps to challenge a denial by testing whether the committee's authority and standard actually trace back to your recorded documents.
- 01
Confirm condo or subdivision HOA
MCL § 559.147 applies only to condominiums. A subdivision HOA's architectural authority, if any, comes entirely from its own declaration.
- 02
Pin the denial to an actual document clause
Ask the board or committee, in writing, exactly which provision of the master deed, bylaws, or declaration authorizes control over the specific feature you were denied on.
- 03
For condo interior work, check the one hard statutory line
MCL § 559.147(1) protects interior alterations that don't impair structural integrity or support, regardless of what the board otherwise prefers.
- 04
For subdivision HOA denials, argue the document, not the statute
Since no Michigan statute reaches architectural review outside a condo, build your appeal around your declaration's actual words and any ambiguity in the board's authority.
- 05
Gather comparable approvals
Photograph and date similar projects the board or committee approved elsewhere in the community. Inconsistent decisions are your strongest lever when the statute itself won't help you (see the selective-enforcement guide).
Straight answers
Common questions
Can my Michigan condo association control my unit's exterior?
Yes, but only to the extent its own condo documents specify. MCL § 559.147(1) ties exterior-appearance control entirely to what the master deed and bylaws provide, rather than granting the association an independent statutory power.
Can I renovate the inside of my condo unit without approval?
Generally yes, so long as you don't impair the structural integrity of the building or lessen support for any part of the project, a protection MCL § 559.147(1) gives you regardless of what the association would otherwise prefer.
Does Michigan protect solar panels, flags, or EV chargers from an HOA ban?
Not under the Condominium Act or the Nonprofit Corporation Act. Michigan hasn't carved out a protected category for any of these the way some states have; whatever protection you have lives in your own declaration, not in state law.
What if my subdivision HOA denies my project and there's no statute to fall back on?
Then your fight is entirely about your declaration's actual language and comparable approvals elsewhere in the community, since Michigan's Nonprofit Corporation Act doesn't address architectural review at all.
