Work is underway on The Chester at Westlake, a seven-story mixed-use apartment building at 99 Southgate Avenue in Daly City. The project will deliver 214 apartments above a two-story concrete podium garage on a 1.93-acre site, plus roughly 10,000 sq ft of ground-floor retail. The building will feature varied facade materials, private balconies for most units, and over 13,000 sq ft of shared amenities including a fitness center, co-working space, landscaped courtyards and a rooftop sky lounge.

Work has officially started on a seven‑story, mixed‑use apartment building at 99 Southgate Avenue in Daly City. The project, called The Chester at Westlake, will bring 214 apartments above a two‑story concrete podium garage on a 1.93‑acre site. The development team expects the building to open in winter 2027.
The Chester is being built between the Westlake Shopping Center and an adjacent apartment complex and is described as the first new predominantly market‑rate mixed‑use apartment community to break ground in Daly City in about 15 years. The project adds both housing and street‑level retail to a long‑standing neighborhood shopping area and is part of a broader wave of housing activity nearby.
The building will rise roughly 85 feet and include more than 350,000 square feet of total interior area. About 250,000 square feet is planned for housing, with nearly 10,000 square feet of ground‑floor retail. Parking will occupy less than 100,000 square feet and provide space for 288 cars inside the two‑level podium garage, yielding a 1:1.35 ratio of apartment units to parking spaces.
The 214 units will include studios and one‑, two‑ and three‑bedroom layouts. More than two‑thirds of the homes will include a private balcony or terrace. Common amenities are planned to total over 13,000 square feet and will include a fitness center, yoga room, co‑working space, a communal bar, two landscaped courtyards and a rooftop sky lounge.
The design calls for a contemporary podium‑style apartment building with varied facade materials to reduce perceived massing. Exterior cladding shown in approved plans includes fiber cement panels, traditional siding, board‑formed concrete and stucco. Design and delivery teams listed for the project include an architectural firm, landscape architect, civil engineer, interior designer and a general contractor selected to construct the development.
Two companies are partnered as joint developers on the project, with one serving as lead developer and the other focused on retail operations given its long‑standing ownership of the adjacent shopping center. Construction financing has been provided by a major national bank.
The site sits within walking or short bicycle distance of bus routes that connect to Daly City BART in about eight minutes by bus or bike, and nearby bus stops are served by at least two routes, one with frequent service. Project planners note the location’s transit options, while other local observations note that many regional trips are still made by car. The garage will hold 288 vehicles, and roughly 28% of the building’s interior area is devoted to parking by the project’s own internal calculations.
The site occupies a portion of the Westlake District adjacent to a shopping center that first opened in the early 1950s and helped shape postwar growth in the area. The new project joins nearby housing work that includes a multi‑phase affordable housing redevelopment now delivering and planning several hundred apartments, along with an early‑phase childcare facility tied to the affordable project.
Construction is underway and the project team anticipates delivery and opening as early as winter 2027. If completed on schedule, the building will add a substantial number of new market‑rate homes and retail space to the Westlake neighborhood within the next two years.
