Common modifications include grab bars in bathrooms, non-slip treads on entry steps, adequate exterior lighting, a walk-in shower, and a plan (whether a hired service or a family arrangement) for reliable snow and ice removal from walkways before a senior attempts to walk them.
More detail
Milwaukee's winters bring a specific, seasonal fall risk that milder-climate cities simply don't have to plan around: icy front steps and unshoveled sidewalks are a leading cause of injury for seniors trying to age in place here between roughly November and March. A modification plan that only addresses the interior of the home misses this major seasonal risk entirely. Beyond physical modifications, many Milwaukee-area families arrange for a snow-removal service, a neighbor, or a paid caregiver to handle walkway clearing specifically, rather than assuming an aging parent will either do it themselves or simply stay inside until spring, which carries its own isolation and mobility risks.
