San Francisco has approved plans for 159 affordable senior apartments on the Laguna Honda Hospital campus, alongside a senior center, space for in-home support services, and a proposed early childhood education center. The scale is significant, but the project has not started construction: building permits have been filed and are awaiting issuance, and the developer’s schedule still depends on funding and further approvals.[1][2]
For Bay Area residents, the proposal is a useful example of how housing can be planned alongside spaces for connection and services. It also shows why an approval milestone matters without being the same as a completed building or a confirmed construction start.
Homes and shared services in one development
Mercy Housing California is developing the project at 356-402 West Clarendon Road in San Francisco’s Twin Peaks area, on a vacant parcel within the Laguna Honda Hospital campus. Mercy Housing’s project page lists the site as 375 Laguna Honda Boulevard, another address associated with the development.[1][2]
Plans call for a 68-foot-tall building with about 120,000 square feet of space. Nearly all the apartments are planned as one-bedroom homes, with a two-bedroom unit for an on-site resident manager. The project is intended for affordable senior housing. Mercy Housing says it is designed to serve independent seniors and older adults who need a higher level of care.[1][2]
Shared amenities are part of the plan, too. Residents would have access to a community room, two laundry rooms, and a landscaped courtyard. A senior center is intended to serve both residents and people in the surrounding community. The building also includes office space for residential services and an In-Home Supportive Services provider.[1]
The plans include an approximately 7,000-square-foot early childhood education and daycare center, with capacity for about 50 children ages zero to four. That center is proposed as part of the future development. It is not a service currently operating in the new building.[1]
The combination of senior housing, services, a community center, and childcare puts different age groups and resources within one development. The plans describe the intended spaces, but they do not establish how services will operate, who will provide them, or when they will open. Those details will require confirmation as the project advances.
Accessibility, transportation, and design
The project description identifies about half of the affordable apartments as mobility units. Another 10% are designed to assist people with hearing or visual impairments.[1] These features are important in senior housing, where a home’s design can affect residents’ ability to move around and use everyday spaces. Final details will matter, including how accessibility features are delivered in the completed building.
The roughly 1.5-acre site sits within Laguna Honda’s 75-acre campus, near the Forest Hill light-rail station and amid the area’s tree-covered hills.[1] The project plans include 31 vehicle spaces and 18 bicycle spaces. Those numbers describe parking provisions, but do not by themselves indicate what transportation options future residents will use.
Herman Coliver Locus Architecture is the project architect, and TS Studios is responsible for landscape architecture. The proposed exterior combines fiber-cement siding, painted cement plaster, and cast-in-place concrete, with yellow and orange tones. The landscape plan includes paved paths, seating areas, wood trellises, and loose gravel mulch.[1]
What approval means, and what remains
San Francisco’s planning approval is a significant step, but it is not the same as building-permit issuance or a construction start. The project’s building permits have been filed and were awaiting issuance in the October 23, 2026 report.[1]
The project used Senate Bill 423 and California’s State Density Bonus Law as part of its approval approach. San Francisco Planning describes SB 423 as a qualifying streamlined ministerial review pathway for eligible housing projects. California’s Density Bonus Law can allow eligible projects additional density and incentives or concessions, subject to the law’s requirements.[3][4][5] These rules shape how qualifying projects are reviewed; they do not mean that every later step, such as funding or permit issuance, is already complete.
The reported construction estimate is around $70 million, excluding some development costs.[1] Mercy Housing’s project page lists a funding application for spring 2027, a target construction start in fall 2027, and a target completion in fall or winter 2029. The page also says construction will begin no earlier than 2027.[2] These are planned milestones, not guarantees. Funding, permits, and other approvals remain important conditions.
| Milestone | Current or expected status |
|---|---|
| Planning approval | Approved, as reported October 23, 2026.[1] |
| Building permits | Filed and awaiting issuance in the October 23 report.[1] |
| Funding application | Planned for spring 2027, according to Mercy Housing.[2] |
| Construction | Mercy Housing target: fall 2027, subject to funding and approvals. Construction is not reported as underway.[2] |
| Completion | Mercy Housing target: fall or winter 2029, subject to project progress.[2] |
Who may qualify for the apartments?
Mercy Housing describes the intended residents as seniors in households below 50% of the area median income, or AMI. AMI is a regional income benchmark used in affordable housing programs. The project page notes that many apartments are intended for very low-income households with fixed incomes. Actual eligibility and any applicant preferences will depend on funder requirements and formal marketing for the development.[2]
Mercy Housing says apartments will be marketed through San Francisco’s housing portal.[2] The page does not provide a current application opening date. People interested in future availability should check the portal and Mercy Housing’s Laguna Honda project updates rather than assume applications are open.
Why the project matters beyond its unit count
The proposal brings housing and shared community spaces together on a site already associated with health care. That arrangement may make it easier to coordinate services and create places for residents and neighbors to gather, although the plans alone cannot establish how accessible or effective those services will be once the development is operating.
For Oakland and East Bay readers, the broader lesson is practical: housing proposals have multiple stages, and each stage answers a different question. Planning approval indicates that a project has cleared a land-use review milestone. Permit issuance, funding, construction, and eventual occupancy are separate steps that must still be completed. Following those distinctions helps residents, community organizations, and advocates assess progress without mistaking a proposal for a finished resource.
The Laguna Honda development is led by Mercy Housing California, selected by San Francisco’s Mayor’s Office of Housing and Community Development through a competitive process, according to Mercy Housing.[2] It is a San Francisco project, not an MFFCE-funded or MFFCE-operated development. Oakland residents seeking local housing context can also read MFFCE’s overview of affordable housing in Oakland.
