9421 Edinger Avenue is a well-positioned, stand-alone commercial building in central Westminster, CA, offering a prime opportunity for healthcare, adult services, or professional office use. Previously operated as an adult day care center, this 3,775 sq ft single-story facility sits on a large 16,553 sq ft lot, featuring spacious back and side yards ideal for outdoor patient activities, staff breaks, or future expansion. The building is thoughtfully equipped for healthcare or service-based operations, with high 11’ ceilings, open interior layout, central HVAC, a kitchen, and shower facilities. With 16 on-site surface parking spaces, security fencing, and 24/7 access, the property supports smooth and secure daily operations. Located directly on Edinger Avenue, a major arterial road in Westminster, the site benefits from high visibility, strong traffic counts, and proximity to the 405 Freeway, Beach Blvd, and Bolsa Ave. The surrounding area includes a large residential base and the thriving Vietnamese-American community—providing built-in demand for medical, wellness, or senior services. An exceptional added value is the cell tower lease, which generates $2,000/month in passive income, equating to roughly $500,000 in added asset value. This income stream offers reliable cash flow for owner-users or enhances cap rate for investors. Whether you’re a medical group, dental clinic, wellness provider, or operator of adult day health care or similar community services, this property is well-suited to meet regulatory, logistical, and functional demands. Investors will also appreciate the flexible use zoning and potential for income from both tenancy and telecom infrastructure.
