SB 79 just legalized 1.5 million new homes near transit in the City of LA

Streets 4 All did an analysis which found that SB79 could potentially double LA City's total housing stock, even when fully accounting for various exemptions/compromises and conservative estimates. Their conclusions:

1. SB 79 will eventually zone nearly 1.5 million (1,456,150) new units of housing in the City of LA. This would be enough to double LA’s current housing stock of 1.37 million homes
2. It will immediately zone for 448,260 new units when SB 79 goes into effect July 1, 2026, and upzone for at least another 1,007,890 units of housing during RHNA Cycle 7 in 2031
3. SB 79 will impact 17,929 acres, or a little over 5% of the City’s land. Half of impacted acres were previously zoned exclusively for single family homes (9,953 acres).

Of course not all of this housing is going to be immediately developed due to other factors like demand, construction costs, interest rates as well as willing buyers/sellers of SFH plots. That said, its reasonable to expect at least around ~1/3 of this capacity, or half a million units, possibly being developed in the long term over the next 2-3 decades, which could represent a >30% increase in LA city's housing supply alone, which can accommodate future growth without creating significant pressure on existing housing stock/prices.
