MI HB4045

Allows applications for neighborhood enterprise zone certificates to be filed up to 6 months after a building permit is issued, instead of requiring pre-permit filing.

Adds multiple exceptions to pre-permit filing requirements for specific zones designated in particular years (1992-2007) with corresponding building permit date windows.

Permits post-permit applications for homestead facilities and qualified historic building rehabilitations without time restrictions.

Requires homestead facility applicants to commit to a minimum $500 investment over 3 years and document the investment if requested by the assessor.

Establishes effective dates for certificates based on when they are approved, typically the first day of the tax year following approval or January 1 for certain rehabilitated facilities.
