An underused piece of the Spring Street trolley station's park-and-ride lot is beginning a second life as housing. County and local officials broke ground Friday on Spring View Apartments, a six-story, 147-unit affordable development in La Mesa planned beside the San Diego Trolley line.

The mix runs from studios to one-, two- and three-bedroom apartments for individuals, families and veterans earning between 30% and 60% of area median income. That range matters at the household level: it is broad enough to include a single worker seeking a studio and a family that needs bedrooms, but it also sets income gates that prospective tenants will have to document when leasing begins.

The $106 million project is being developed by Affirmed Housing on surplus Metropolitan Transit System land. The public-private structure converts part of a parking asset into homes without separating residents from the transit network. For households able to use the trolley for work, school or appointments, proximity can reduce the time and expense of a second car. It does not guarantee that every daily trip will fit the rail map.

San Diego County is contributing $8.5 million and supplying 40 project-based rental vouchers. Thirty-six are Section 8 vouchers and four are Veterans Affairs Supportive Housing vouchers, which pair rental assistance with services for eligible veterans. Because the assistance is attached to designated apartments, it preserves affordability at the property rather than traveling with a tenant who moves.

The remaining 107 homes will still carry the project's stated income restrictions, but the county announcement did not publish proposed rents, a lottery calendar or an anticipated opening date. Those details will determine when a groundbreaking becomes practical access. For renters watching from La Mesa and nearby East County neighborhoods, an address and unit count are only the first stage of the application process.

Plans include outdoor gathering areas, children's play space, a basketball hoop, barbecue stations, a community room, activity centers and computer rooms. On-site solar energy and high-efficiency building systems are also part of the design. Shared amenities can make a dense project work better for families, especially when private units are smaller, but their value depends on management, hours and long-term maintenance.

The county places Spring View within a larger capital record. Since 2017, it says it has invested more than $330 million in affordable-housing infrastructure, helping create more than 3,900 homes through surplus land and Innovative Housing Trust Fund financing, with nearly 2,200 more in development. Those figures come from the county and were not broken down by completion status, rent level or neighborhood in the announcement.

Spring View's promise is unusually legible from the platform: housing, transit and county rental assistance are being assembled on the same site. The harder work comes after the ceremony. Construction must stay within a $106 million plan, the voucher apartments must reach the households they are intended to serve, and leasing information must arrive early enough for families to prepare. Until then, the park-and-ride conversion is a funded route toward 147 homes, not 147 keys in renters' hands.
