California Mission Inn in Rosemead offers both Assisted Living and Independent Living, giving residents the option to choose the level of daily support they need while remaining in the same community. Those who are largely self‐sufficient can take advantage of Independent Living services, and individuals who require help with activities of daily living—such as bathing, dressing, and medication reminders—may opt for Assisted Living.

The community maintains a secured environment and supports a range of medical needs. Short-term respite stays are available, making it a practical choice for families needing temporary care solutions. Onsite doctor oversight, diabetes management programs, speech therapy, and multiple levels of care allow residents to receive attention geared to changing health conditions without moving to another facility.

Apartment options include wheelchair-accessible showers, kitchenettes, Wi-Fi, cable or satellite TV, air conditioning, and some apartments have private decks, balconies, or patios. Select units are handicap accessible, pet friendly, and near common areas such as the central fireplace or piano lounge. Not all accommodations have all these features, so it is best to confirm specifics during a visit. Outdoor areas and on-site parking add convenience for residents and visitors.

Dining is prepared by a professional chef and served restaurant-style, with meals available throughout the day. The kitchen can accommodate vegetarian, vegan, gluten-free, low- or no-sodium, and no-sugar preferences, and international menu options are rotated regularly. Guests are welcome to join residents for meals, providing flexibility for family visits.

Amenities include an activity center, indoor and outdoor walking paths, access to outdoor spaces, yoga and chair yoga classes, fitness programs, swimming pool, live music, karaoke, dances, happy hours, birthday celebrations, social outings, and clubs and communities that meet in the library and computer lounge. Reminiscence and sensory-based programs are offered, supporting residents who benefit from structured cognitive activities.
