Construction underway at The Chester at Westlake, a seven-story mixed-use apartment building in Daly City's Westlake District.
Daly City, California, September 7, 2025
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. Developers say the project will add market-rate housing and street-level retail to the Westlake neighborhood.
Construction has started on a new seven‑story, mixed‑use apartment building at 99 Southgate Avenue in Daly City. The project will add 214 apartments above a two‑story concrete podium garage and is on track for opening in winter 2027.
The development sits on a 1.93‑acre parcel in the Westlake District, positioned between an existing shopping center and an adjacent apartment community. The building will rise roughly 85 feet with about seven stories of living space and a podium garage. Total gross area will top 350,000 square feet, with roughly 250,000 square feet allocated to housing.
The 214 units will include studios and one‑, two‑, and three‑bedroom apartments. More than two‑thirds of units will have a private balcony or terrace. Ground‑floor retail space will total nearly 10,000 square feet. The two‑story podium garage will provide 288 parking spaces, yielding an apartment‑to‑parking ratio of about 1:1.35 and occupying under 100,000 square feet of the building interior, or roughly 28 percent of interior area.
Shared amenities will include a fitness center, yoga room, flexible co‑working space, a communal lounge area, two landscaped courtyards, and a rooftop sky lounge. Reports indicate the amenity program will exceed 13,000 square feet.
The design is a contemporary podium‑style scheme with façade articulation and material variation to break up massing. Exterior cladding shown in design materials includes fiber cement panels, siding, board‑formed concrete and stucco. The architect and consultants on the project are handling building, landscape, civil and interior design work, while a general contractor manages construction. Financial backing for the build phase is coming from a major banking institution.
The project is a joint venture between two experienced development firms. One firm will lead development and day‑to‑day project delivery while the other focuses on the retail and property ownership relationship, continuing a long‑standing ownership presence at the neighboring shopping center. This is the partners’ second joint venture together, following a development located on Philadelphia’s Main Line.
The site has multiple local transit connections. Bus and bicycle routes will reach a regional rail/transit station in about eight minutes, and local bus routes serve nearby stops with at least one route offering frequent service every 10 to 15 minutes. Project materials note that the location can support residents who rely on transit and active travel, while also recognizing that many people in the area continue to drive.
The ground‑breaking comes amid several housing projects in the city. A nearby multi‑phase affordable housing redevelopment has recently opened its first phase and is advancing a second phase scheduled for delivery by the end of 2027. That redevelopment will provide hundreds of new affordable units across multiple phases, including family units and a sizable childcare center when complete.
Construction is now underway, with substantial completion and initial occupancy expected as early as winter 2027. Site work, below‑grade and podium garage construction are immediate priorities before work on residential floors and exterior finishes advances.
The project is located at 99 Southgate Avenue in the Westlake District of Daly City.
The building will contain 214 apartments, including studios and one‑, two‑ and three‑bedroom units, with more than two‑thirds featuring private balconies or terraces.
Construction has begun and the development is scheduled to open in winter 2027.
There will be 288 parking spaces in a two‑story podium garage, an approximate ratio of 1:1.35 parking spaces per unit.
Amenity offerings include a fitness center, yoga room, co‑working space, communal lounge/bar area, two landscaped courtyards, and a rooftop sky lounge, totaling over 13,000 square feet of amenity space.
The project is a joint development venture between two firms; construction financing is being provided by a major banking institution.
The site is within an eight‑minute bus or bicycle ride to the regional rail/transit station and sits close to multiple local bus routes with frequent service on at least one route.
