The rebuilding process in Altadena, California, a community devastated by the January 2025 Eaton Fire, has become a flashpoint for a larger debate over housing affordability and local control. As residents grapple with the slow pace of recovery and a critical housing shortage in the Los Angeles area, a proposed state law, SB 1090, could suspend a law that allows for denser housing development on fire-scorched lots.
Testing Pro-Housing Reforms
The dispute highlights the challenges California has faced for years in addressing its housing crisis. The state has enacted laws aimed at weakening exclusionary zoning, legalizing denser housing options like "missing middle" units, and shifting some housing decisions away from local governments. Among these are Senate Bill 9, which allows homeowners to build up to four units on single-family lots, and SB 1123, which permits the subdivision of vacant lots for up to 10 smaller homes.
In Altadena, a suburb north of Los Angeles, the Eaton Fire destroyed a significant portion of homes. While many survivors are rebuilding single-family residences, others, facing financial pressures from low insurance payouts and high construction costs, are exploring higher-density rebuilding or selling their lots to developers. This has led to opposition from some residents who fear that denser developments will alter the character of their community, even as state laws were intended to facilitate such rebuilding.
SB 1090, if passed by August 31, would suspend SB 1123 in Altadena until 2030, effectively blocking the increased housing density it would allow. Proponents of the bill, including some fire survivors like Neil Tyler, express anxiety that developers could transform burned lots into clusters of homes that feel incompatible with the Altadena they wish to reclaim. Tyler voiced concerns that developers might profit from residents' pain and suffering by building housing that feels alien to the pre-fire neighborhood.
The Economics of Housing and Density
Supporters of state housing reforms argue that density is crucial for affordability. When demand for housing outstrips supply, prices rise, a phenomenon long observed in the Los Angeles region. Historically, restrictive local zoning, particularly single-family zoning, has limited housing construction. The median home value in Altadena is around $1.12 million, largely due to this scarcity.
Proponents of SB 1123, such as Azeen Khanmalek, executive director of Abundant Housing LA, argue that allowing more units on a single lot can increase land value, making it more feasible for original homeowners to rebuild or for new buyers to access less expensive housing. A simplified economic model suggests that a parcel zoned for multiple smaller homes can justify a higher land price for a developer compared to one zoned for a single large home, potentially creating a positive-sum outcome for sellers, buyers, and builders.
Caroline Paules, an Altadena resident and co-founder of a prefabricated cottage startup, believes that denser rebuilding is necessary, even if it means accepting changes to the community's form. She stated that while the desire for Altadena to return to its pre-fire state is understandable, clinging to the past might be preventing necessary adaptation.
Local Control vs. Regional Needs
The conflict has also involved shifts in local government actions. The Los Angeles County planning department initially promoted SB 9 and SB 1123 as rebuilding options but later voided applications under SB 1123, arguing that the parcels did not qualify as infill projects due to the widespread destruction. This reversal echoed a similar suspension of SB 9 in the Pacific Palisades after the fires.
Much of the recent controversy has centered on Stone West Homes, a developer that purchased seven Altadena lots with plans to build approximately 10 small houses on each. After LA County canceled its application, the developer sued. The fight then moved to the state legislature, leading to SB 1090, sponsored by State Sen. Sasha Renée Pérez.
Opponents of denser development, particularly those fearing "disaster capitalism" by outside speculators, have rallied behind SB 1090. However, proponents of housing reforms question this narrative, arguing that developers are essential for building needed homes. Some residents, like Neil Tyler, express concern that denser developments, even if not high-rise buildings, could disrupt their desired way of life. However, others, like Paules, question how such developments would actively harm residents.
Fire Risk and Future Development
While Altadena is in a fire-prone area, wildfire experts note that density has a complex relationship with fire risk. Building more densely within existing communities is often seen as preferable to expanding development into wildland areas. Experts suggest that improved fire resistance, vegetation management, and evacuation planning are more effective risk reduction strategies than blanket restrictions on density. SB 1123 itself has provisions allowing local governments to reject developments deemed a threat to public health and safety.
Organizations like California YIMBY suspect that the proposed moratorium in SB 1090 could become permanent, setting a precedent for other communities to seek exemptions from state housing laws. The ultimate decision may rest with Governor Gavin Newsom, whose administration has generally supported state housing reforms against local opposition. The outcome of SB 1090 will be a significant test of California's commitment to increasing housing supply amid disaster and local resistance.
