Board advances changes to group-housing definition to tighten common-space and kitchen rules

The San Francisco Board of Supervisors on Tuesday advanced on first reading an ordinance to revise the city's planning code definition of "group housing," tightening minimum common-space and kitchen requirements and clarifying several exemptions.

Sponsor Supervisor Aaron Peskin said the measure aims to remove ambiguity that allowed some recent conversions to claim group-housing benefits while providing minimal communal amenities. The board unanimously approved the measure on first reading and asked that it proceed to final adoption after committee review.

Planning staff briefed the board on a lengthy planning commission and staff review period that followed a 300-plus page study from the California College of the Arts. The study and the subsequent staff recommendations sought clearer, objective standards for group housing so that developers who accept relaxations on livability standards must deliver demonstrable common areas and shared meal facilities.

Key changes: The ordinance raises the common-space ratio to one half square foot of common space for every square foot of private space, requires at least one kitchen per 15 units and clarifies that nonprofit operators such as Ronald McDonald House or Family House that provide temporary accommodations for nonresidents are exempt from the new ratios.

Board members said the changes address earlier confusion that the zoning administrator had described as having been "stretched beyond recognition" in prior permit interpretations. Planning Department staff indicated the rewrite mirrors "best practices" and aligns the definition with successful group-housing models.

Supervisor Matt Haney asked whether the planning commission had recommended the change; Planning Manager Aaron Starr said both the department and the commission recommended approval with certain staff-proposed amendments and that the commission's action to support the revised definition was near unanimous.

What it means: If adopted after committee review, the ordinance will make it harder for applicants to claim group-housing benefits without delivering increased common areas and shared kitchens. Proponents said the change will protect residents' quality of life and clarify evaluation standards; opponents argued the stricter rules could affect how developers design higher-density projects. Planning staff said the changes preserve group-housing's intent: incentives in exchange for onsite shared stewardship and resident community building.

Ending: The board advanced the ordinance on first reading unanimously and indicated further committee review before final adoption.
