Township ordinances follow the same pattern. A true copy or a summary is published once in a local newspaper within 30 days after passage, and MCL 41.184 (opens in a new tab) says nothing about websites. A searchable ordinance page helps residents, but it doesn't replace that publication.
Cities, townships, villages, counties and special districts can all get a free .gov domain, and Michigan doesn't require one. A .gov address does make it easier for residents to trust that a notice really came from the local government. (get.gov (opens in a new tab))
