MI SB0272

Modifies the definition of "undeveloped land" in Michigan's Condominium Act to clarify that condominium units depicted on subdivision plans as containing no vertical improvements are excluded from the undeveloped land classification, regardless of when the condominium project was created.

Allows developers to withdraw undeveloped land or convert undeveloped units to "must be built" status within 10 years of recording the master deed, or 6 years after the last exercise of expansion, contraction, or convertibility rights, whichever ends later.

Permits condominium associations, by two-thirds majority vote, to declare undeveloped land as general common elements after the applicable time period expires, which terminates rights to construct units on that land.

Requires associations to provide 60 days written notice to developers before filing a declaration with the register of deeds, giving developers a final opportunity to withdraw land or convert units.

Updates statutory language throughout section 67 of MCL 559.167, replacing "shall" with "must" and clarifying various procedural references.
