We are designing a 8000 sf addition to an existing hospital and remodeling a small portion of an existing department that is adjacent to the expansion. All new construction will have accessible route, toilets etc. There is a toilet in the remodel area that is NOT ADA accessible. Michigan has a slightly altered IEBC code and they have removed some verbiage that required a 20% of construction dollars needs to go into updating accessibility in the existing building. Does Michigan have a code requirement to spend dollars on accessibility in other areas of their existing building?
