San Francisco's Planning Commission voted unanimously this week to approve sweeping zoning modifications that would allow mixed-income residential development across 12 blocks in the Mission District, marking the most significant housing policy shift since the city's failed Proposition D vote last November.
The decision, finalized Wednesday, removes restrictions that previously limited building heights to 65 feet in the corridors along Valencia Street between 16th and 24th Streets. The new framework permits developers to construct buildings up to nine stories if they dedicate at least 25 percent of units to affordable housing below area median income levels—currently $140,000 for a family of four in San Francisco.
"This represents a pragmatic recognition that we cannot zone our way out of a housing shortage through incremental measures," said a spokesperson for the San Francisco Housing Action Coalition, which has advocated for similar changes for three years. The median rent for a one-bedroom apartment in the Mission now exceeds $3,100 monthly, up 8 percent from last year.
The vote comes amid mounting pressure on city leaders. San Francisco's population declined by 6 percent between 2020 and 2025, with many residents citing housing costs and quality-of-life concerns. The Planning Department estimates the city needs approximately 23,000 additional housing units by 2030 to meet projected demand and stabilize prices.
Not all stakeholders support the changes. Several Mission District community groups expressed concerns about gentrification acceleration and displacement risks, despite the affordable-housing requirements. The Mission has experienced dramatic demographic shifts over the past two decades, with longtime residents increasingly priced out.
Separately, the Board of Supervisors is expected to vote next month on a companion initiative affecting the Tenderloin, where the city owns several parcels near United Nations Plaza. That proposal would permit developers to construct up to 800 units on public land, with 40 percent designated as permanently affordable.
Real estate analysts note the zoning changes provide investors greater certainty. Developers had previously hesitated committing capital to projects with ambiguous building codes. However, affordability requirements remain a cost consideration—the city's current inclusionary housing fee stands at $28 per square foot, placing additional pressure on project economics.
Planning officials will now begin drafting specific design guidelines for the rezoned Mission blocks. Community input sessions are scheduled throughout July at the SOMARTS Cultural Center on South Van Ness Avenue.
