SB 330, the Housing Crisis Act of 2019, restricts California cities from downzoning, adding new discretionary approval hurdles, or letting housing permits sit unprocessed — and 2025's AB 130 made its protections permanent, removing the law's original sunset date.
SB 330 requires cities to flag plan or zoning inconsistencies within a fixed window (30 days for smaller projects, 60 days for larger ones) or the project is deemed compliant, bars new discretionary review layers added after a project vests, and prevents demolition of existing housing without a like-for-like replacement plan and tenant relocation protections.
For LA multifamily sellers and buyers of older, smaller properties eyed for redevelopment, SB 330's no-net-loss and relocation provisions are a real cost and timeline factor to underwrite — replacing existing occupied units isn't optional, and it shapes how a redevelopment pro forma has to be built from day one.
