Diamond Bar RCFE operates as a residential care home and is equipped to support a wide range of medical needs. Staff members monitor residents who wander at any time of day, manage wound care protocols, administer oxygen therapy, and accommodate special diets, including those required by residents under 60 and diabetics who rely on oral medication. The community also accepts residents with advanced dementia conditions and maintains on-site podiatry services for routine foot health and more complex issues.

To reinforce resident safety and timely response, the community conducts background checks on all employees, keeps awake staff on duty throughout the night, and maintains 24-hour staffing with security measures such as a fenced rear area, alarmed doors, pull-cord alerts, and personal emergency response systems. Caregivers provide full assistance with bathing, dressing, and toileting, as well as some physical help at mealtimes. Transfer support ranges from standby supervision to one- or two-person assistance and extends to bed-bound residents, walkers, and wheelchair users.

Accommodation options include furnished rooms, many with private bathrooms, and residents may personalize their spaces with their own décor or choice of paint color. Cable service is available in select rooms, though not every accommodation features each listed amenity.

Meals follow a set menu designed to meet varied dietary requirements, and staff can modify textures or ingredients to align with physician-ordered diet plans. Snacks are offered between meals to help residents maintain stable nutrition and hydration.

The property is wheelchair accessible and offers a barber and beauty shop, internet access, communal gardens, and on-site religious services. Public transportation is nearby, providing an additional travel option for residents and visitors.
