Commission Converts Stalled Mission District Project to 100% Affordable Housing

The San Francisco Planning Commission unanimously unlocked a new path for a decade-old stalled development at Mission and 9th Street, readopting a Special Use District to allow the project to proceed as 100% affordable housing — a first-of-its-kind conversion that commissioners hope becomes a model for stranded market-rate entitlements citywide. The commission also received a sweeping climate adaptation blueprint for Bayview Hunters Point, one of the city's most vulnerable neighborhoods, and greenlit a new home in Presidio Heights over a neighbor's objections about construction near a National Historic Landmark.

• Mission & 9th Street project converts from market-rate to 100% affordable housing in unanimous 6-0 vote, with all units restricted to households at 80% AMI or below for at least 55 years

• Bayview Hunters Point gets sea level rise adaptation strategy after a two-year, $649,000 state-funded study identifies four measures to protect the neighborhood from up to 6.6 feet of projected sea level rise by 2100

• New three-story home approved at 125 Maple Street near the historic La Petite Trianon after commission rejects neighbor's discretionary review request, ruling geotechnical concerns belong at the building permit stage

• DBI-Planning Department merger Phase 1 takes effect, transferring Permit Center and IT staff to Planning, with code enforcement consolidation planned for late 2026-2027

• Commissioner Williams sounds alarm on cultural district bypass after a business was approved over-the-counter in the Calle 24 SUD without the cultural district organization being notified

A First-of-Its-Kind Conversion: Mission & 9th Street Goes 100% Affordable

The basics: The Mission and 9th Street Special Use District was originally created in 2017 to facilitate a market-rate residential project with above-minimum affordable units. The project secured a site permit but never broke ground — the SUD expired in 2022 after no construction documents were obtained within five years, largely because of COVID-related delays. Now the project sponsor wants to build a 100% affordable project on the same site, using the same height allowance of 200 feet and the same code alleviations from the original SUD.

Why it matters: This may be the first time San Francisco has converted a market-rate Special Use District to a 100% affordable housing project — a mechanism that could provide a template for other stalled entitlements across the city. Every unit must serve households earning 80% of area median income or below, income-restricted for a minimum of 55 years.

Where things stand: Staff planner Audrey Merlone presented the conversion, explaining that the project sponsor now seeks to leverage affordable housing financing tools that weren't available under the original market-rate framework. "The project sponsor now seeks to build a 100% affordable project at the site utilizing the same code alleviations and added height that was in the original SUD," she said.

The commission also delegated authority to the Planning Director to administratively amend the original market-rate approval — updating affordability levels, timelines, inclusionary requirements, and impact fees — but only as narrowly needed for the 100% affordable project. Merlone emphasized the guardrails: "The only things that the planning director can approve administratively are in service of being a requirement for the 100% affordable project to move forward. They can't amend anything that is not in service of building that 100% affordable project."

Commissioner Derek W. Braun, who moved the motion, said he was excited to see the conversion. "I'm really excited to see this project come back as a 100% affordable housing project. We have seen a lot of 100% affordable projects moving forward right now when financing is so tough for market-rate projects," he said.

Commissioner Lydia So, who seconded, pushed for urgency after a decade of delays: "I just want to see a ribbon cutting and people moved in in the next two or three years. So please go get this done."

Commissioner Theresa Imperial asked about construction timelines and financing, while Commissioner Gilbert Williams sought clarity on the scope of delegated authority. Land use counsel Nick Roosevelt, representing the project, responded to questions about the project's path forward.

Decisions: The commission voted 6-0 to readopt the SUD and delegate authority to the Planning Director (For: McGarry, So, Williams, Braun, Imperial, Campbell; Absent: Moore).

What's next: The project sponsor will work with the Planning Director on technical amendments to the original motion to enable 100% affordable financing and pursue construction documents.

Bayview Gets a Climate Lifeline: Sea Level Rise Strategy Lands After Two-Year Study

The basics: Yosemite Slough is an intertidal wetland channel in the Bayview Hunters Point neighborhood, surrounded by low-lying land built on porous bay fill. Without action, state projections indicate approximately 0.8 feet of sea level rise by mid-century and up to 6.6 feet by 2100 — enough to cause permanent shoreline inundation and severe inland flooding during storms.

Why it matters: Bayview Hunters Point is one of San Francisco's most climate-vulnerable environmental justice communities, with legacy contamination from the Hunter's Point Shipyard Superfund site and ongoing EPA cleanup of Yosemite Creek. The completed strategy positions the neighborhood for priority state and federal infrastructure funding, including Proposition 4 resilience dollars, 40% of which are earmarked for disadvantaged communities.

Where things stand: Planning staff Jeremy Shaw and Danielle Ngo presented the completed Yosemite Slough Neighborhood Adaptation Strategy, funded by a $649,000 grant from the Governor's Office of Land Use and Climate Innovation. The two-year effort identified four conceptual adaptation measures: seawalls and living seawalls on the northwest and south shorelines; ecotone levees providing gradual wetland-to-upland transitions; ecotone slope enhancement at the head of the slough; and wetlands restoration on the southeast shoreline.

Shaw framed the stakes: "The strategy for the Bayview neighborhood around Yosemite Slough filled a key gap in adaptation planning for one of the city's most vulnerable environmental justice communities."

Community engagement was extensive — eight community ambassador meetings, three public workshops, walking tours, focus groups with Alice Griffith residents and youth, and collaboration with BAYCAT media production. Community priorities centered on nature-based solutions, improved water and soil quality, adaptable and maintainable measures, and better interagency coordination.

The other side: A critical complication: EPA cleanup of Yosemite Creek and Navy remediation of the Hunter's Point Shipyard Superfund site must complete before full adaptation construction can begin. Ngo explained the sequencing challenge: "The remediation efforts need to complete before further adaptation strategies are done. The work of the Navy, the work of the EPA — that needs to be completed so that the neighborhood is cleaned up, and then we continue to protect from projected sea level rise."

Commissioner Braun asked how funding would be phased between this project and the forthcoming citywide Shoreline Adaptation Plan required by SB 272. Shaw noted multiple funding pathways, including Army Corps technical assistance programs and Proposition 4: "We anticipate that 40% of that funding will go to disadvantaged neighborhoods. There are a lot of categories and possibilities within that bucket of funding."

Commissioner Imperial raised questions about the economic impacts of adaptation on the community: "Should we plan in terms of anticipating impact, economic impact of this adaptation plan? It sounds like there needs to still be more conversation with the community."

Commissioner Sean McGarry praised the work and the community members who participated: "Yes, the city can do an awful lot more for the Bayview Hunters Point."

Two public speakers urged the commission to prioritize the neighborhood. Linda Richardson, a former Planning Commissioner and long-time Bayview resident, called the strategy the most important plan for the area in a decade. Judith Keenan, a Bayview resident, carpenter, and photographer who documented conditions at the slough, described the area as neglected and urged immediate attention rather than waiting for the neighborhood to reach the top of the city's priority list.

What's next: The strategy will feed into the citywide Shoreline Adaptation Plan required by SB 272, due later this year. Construction of adaptation measures depends on completion of federal remediation at the Shipyard and Yosemite Creek sites.

New Home Approved Near National Historic Landmark Despite Neighbor's Structural Fears

Why it matters: The commission's decision reinforces that geotechnical and structural concerns — even near a National Historic Landmark — are addressed at the building permit stage through the Department of Building Inspection, not during planning entitlements.

Where things stand: The owner of 3800 Washington Street — La Petite Trianon, an 1902-1904 building that is both San Francisco Historic Landmark #95 and a National Historic Landmark — filed a discretionary review request against a proposed three-story single-family home with basement on an adjacent empty lot at 125 Maple Street. June Coleman, representing the La Petite Trianon owner (Doe Capital Inc.), argued that excavation for a 12-15 foot retaining wall in dune sand could cause the historic property's land to collapse. Civil engineer Rob Colosimo testified that a significant setback from the lot line would be required, potentially reducing the building footprint by up to 25%.

The other side: Project architect and sponsor Steven Sutro pushed back: "It's simply not true that you need a 10 foot setback to build a retaining wall at the property line. This is done downtown all the time." He described hand-dug pier construction methods that are proven and common in San Francisco residential construction.

Architect Trent Greenan confirmed the project complies with the Planning Code and residential design guidelines, noting that geotechnical and structural review occurs during the building permit process through DBI.

Commissioner McGarry moved to deny the DR, pointedly characterizing the neighbor's position: "I don't believe my neighbor is — I'm an extension of my neighbor's garden. And this is what I see here — basically somebody who sees somebody else's property as an extension of their garden." Commissioner Williams acknowledged the requester's legitimate concerns but agreed the issue was outside the commission's purview. Commissioner So noted the project architect's reputation.

Decisions: The motion to not take DR and approve the project passed 6-0 (For: McGarry, So, Williams, Braun, Imperial, Campbell; Absent: Moore).

Streamlining's Blind Spot: Cultural Districts Lose Their Voice?

Why it matters: As state and local laws make more housing and small business projects ministerial — bypassing commission review entirely — neighborhood-specific protections like cultural district Special Use Districts may be losing the community review processes that have helped preserve their identity for decades.

Where things stand: Commissioner Williams flagged a recent case in which a business was approved administratively via over-the-counter permit within the Calle 24 cultural district SUD — without the cultural district organization even being informed. "Our cultural districts are very important to San Francisco, and they've been able to maintain themselves because of these policies and rules that apply to small business in their cultural districts," he said.

Staff confirmed that commission workload has declined from peak years, with many housing projects now processed ministerially and small business regulatory requirements reduced over the past five to ten years. Staff committed to reaching out to the Mission neighborhood liaison to investigate the specific Calle 24 instance.

Public commenter Sue Hester reinforced the concern, arguing that legislative changes should be presented publicly at the commission rather than posted online, and that area plans adopted with months of community work should not be altered without proper public notice.

What's next: Staff will investigate the Calle 24 case and report back. The broader question of how streamlined permitting interacts with cultural district protections remains unresolved.

DBI Merger Phase 1 Takes Effect

The first and largest phase of the DBI-Planning Department merger takes effect today, transferring Permit Center customer service staff and back-office teams — including project managers, data analysts, and engineers — into the Planning Department. No public-facing changes are expected in this phase. Code enforcement functions, the core chartered DBI operations, will be addressed in a third phase after the November 2026 election, likely in late 2026 or 2027.

Commissioner Williams urged better public communication: "I just think it would be helpful for the public to understand if there was some kind of an outline or a rough idea of the process that is going to be taking place over the next several years."
