MI SB1475

Amends Michigan's governmental immunity law to clarify that municipal corporations must maintain existing sidewalks adjacent to municipal, county, or state highways in reasonable repair.

Creates a rebuttable presumption that a municipal corporation maintained a sidewalk in reasonable repair if a discontinuity defect measures less than 2 inches vertically.

Limits municipal corporation liability for sidewalk defects to cases where the municipality knew or should have known of the defect at least 30 days before injury and the defect was a proximate cause of the injury.

Specifies that governmental agencies' duty to maintain highways extends only to the improved portion designed for vehicular travel, excluding alleys, trees, and utility poles.

Applies the 2-inch discontinuity threshold presumption to any sidewalk maintained by a municipal corporation, which can be rebutted by evidence of specific dangerous conditions that caused the injury.
