Marketing description
Originally constructed in 1970 as a medical office building, 1220 Rossmoor Parkway (the “Property”) served the Rossmoor Active Adult community for decades. The Property was last leased to John Muir Hospital for over 15 years, and now represents a rare redevelopment opportunity in one of Northern California’s most senior-focused markets.
The Property is ideally located just 0.45 miles from the gates of Rossmoor, the largest senior community in Northern California with ±10,000 residents. It sits at the center of a vibrant healthcare and residential care corridor, surrounded by assisted living, skilled nursing, and memory care facilities. The location is also just minutes from Highway 24 and I-680, providing easy access to and from neighboring communities.
Directly adjacent to the site is the newly renovated Rossmoor Shopping Center, a ±120,000 RSF retail destination anchored by Safeway, CVS Pharmacy, and Starbucks, along with a variety of shops and services that serve as key amenities to the surrounding population. The Property is centrally positioned between the affluent communities of Alamo and Lafayette, offering strongdemographics and a built-in base of demand.
Zoned to permit care-related uses, the site was previously approved by the City of Walnut Creek in 2022 for a 139-unit assisted living facility—validating its potential for senior housing or healthcare development. This is a unique opportunity to redevelop in a location that is already established as a hub for senior living and services.
