Heritage Woods of McHenry operates as an assisted-living community, supporting residents who need help with daily tasks such as bathing, dressing, medication scheduling, and routine mobility. The assisted-living team coordinates care plans with residents, families, and physicians to ensure support levels are adjusted as needs change over time.

On-site medical capabilities include diabetes management and access to a licensed speech therapist, giving residents direct support for blood sugar monitoring, insulin administration, and communication or swallowing challenges. Each apartment is equipped with an emergency call system that links residents to staff around the clock, which helps provide prompt attention in case of a fall, medical concern, or other urgent situation.

Apartments at Heritage Woods of McHenry include studio floor plans that offer central air conditioning, individually controlled heat and air, cable TV hookups, and wall-to-wall carpeting, while select units add features such as in-unit washer and dryer, phone connection, wheelchair-accessible showers, fireplace, or direct access to outdoor areas. Parking is available for residents who still drive, and outdoor gardens offer space for fresh air, though not every apartment has every listed feature.

The dining program includes three daily meals planned to match nutritional guidelines for older adults, with staff able to accommodate physician-ordered diets and preferences. Between meals, residents have access to healthy snacks, and the culinary team can adjust menus for individuals who require modified textures or carbohydrate-controlled options for diabetes management.

Residents can spend time in the activity center, take part in bingo or arts and crafts, join organized social outings, visit the library and computer lounge, or relax at the indoor swimming pool. Clubs and small community groups meet regularly, and outdoor common areas are open for fresh air and informal gatherings.
