Housing & land use
SB 79 and Option C1
Why Brian Rosenstein supported a phased approach to transit-oriented housing rather than an all-or-nothing vote.
What SB 79 does
Senate Bill 79, the Abundant and Affordable Homes Near Transit Act, was signed by Governor Gavin Newsom on October 10, 2025 and took effect July 1, 2026. The law establishes state development standards for qualifying residential and mixed-use projects near certain rail, bus rapid transit, and other transit stops. The details vary by transit category and distance from a station; the official bill text, rather than this essay, controls.
SB 79 also gives eligible local governments a limited path to phase implementation when they adopt compliant local rules. That distinction matters in Los Angeles: the policy question was not simply whether to permit transit-oriented housing, but how the City should map, sequence, and pair the state standards with local housing rules.
The Los Angeles process and Option C1
The City Council reviewed implementation approaches on March 24, 2026 and directed City Planning to prepare ordinances based on a phased approach. City Planning then brought the SB 79 Phased Implementation Ordinance and Low-Rise Ordinance to the Los Angeles City Planning Commission for a public hearing on May 14, 2026.
The option Brian referred to as “Option C1” paired phased SB 79 implementation with the first of the upzoning options analyzed by City Planning. The Department’s SB 79 fact sheet and implementation overview reported preliminary modeling in which approximately 88% of qualifying sites could follow a phased implementation path, while roughly 12% would be subject to the state provisions at the outset. Those are planning estimates tied to the maps and assumptions used at that stage, not a count of homes that will be built.
Brian’s first-hand role
Brian participated in the May 14 hearing as a member of the Los Angeles City Planning Commission. His role was to evaluate the ordinances and the public record presented to the Commission; it was not to write SB 79 or make the final City Council decision. The Commission’s amended findings are preserved in the official records for case CPC-2026-1797-CA and case CPC-2026-1798-MSC.
His support for Option C1 was a policy judgment: California and Los Angeles need more homes near transit, but sequencing can reduce avoidable conflicts, give residents and project teams clearer rules, and allow local implementation to respond to fire-hazard, industrial, historic-resource, and other site conditions recognized in the public record.
Why implementation matters
Good policy can still produce unintended consequences when implementation moves faster than mapping, infrastructure planning, and public understanding. How housing is built matters alongside how much is built. In Brian’s view, a phased route was preferable because it advanced housing production without treating every transit-adjacent site or neighborhood as identical.
That is an opinion, not a finding in the staff reports. Readers can reasonably prefer faster statewide implementation or a different local alternative. The underlying principle Brian keeps coming back to is that housing supply, affordability, transit access, and neighborhood stability should not be reduced to competing slogans. Planning works best when it studies practical effects, listens in public, and creates rules that can earn durable support.
