South San Francisco’s downtown will look a lot different in the next few years. Caltrain is moving its South San Francisco station closer to downtown and hundreds of housing units will be built over the next few years, transforming South San Francisco into a transit-oriented community.

The new downtown is part of the city’s El Camino Real/Chestnut area plan, which envisions up to 4,800 housing units in low- to high-rise buildings in a mixed-use walkable community. The additional housing in downtown also will complement the significant life science development projects at Oyster Point, which will add millions of square feet of office/R&D space.

The biggest housing project near downtown will be a six-acre development on Mission Road, which would create up to 1,000 units. The city recently narrowed down a list of potential developers for that site and will make a final decision in March. Developers in the running have proposed 500 to 900 units.

Developers already have proposed and begun building multifamily projects near downtown. Check out some of the high-density projects in the pipeline:
