More than a year and a half later, rebuilding remains slow. All this is unfolding in a region already short of homes, with one of the most expensive housing markets in America.</p> <p>California’s legislature is set to vote on a law that could exacerbate the situation, responding to local anti-density pressure. This reflects a broader trend in the U.S. where local control is prioritized over housing development, complicating efforts to address the national housing shortage.</p> <p>The roots of this dispute extend back before the fires. California has been attempting to resolve the contradiction of needing more homes while facing local opposition to where they should be built. The state has passed laws to weaken exclusionary zoning and legalize denser housing, taking some housing decisions out of local governments' hands.</p> <p>In 2021, Senate Bill 9 was enacted to allow homeowners to build up to four housing units on their lots, and subsequent laws expanded options for subdividing lots. The 2025 fires are now testing these pro-housing measures. In Altadena, many survivors are rebuilding single-family homes, while others are seeking to build higher densities to manage costs or selling their lots to developers.</p> <p>Despite a small number of rebuilding applications utilizing SB 9 or SB 1123, opposition has emerged against denser developments. Lawmakers are considering SB 1090, which would suspend SB 1123 in Altadena until 2030, limiting additional housing development.</p> <img alt="Protesters in Altadena hold signs supporting SB 1090, including one reading “Don’t burn us again,” during a demonstration over post-fire rebuilding and housing policy." src="https://platform.vox.com/wp-content/uploads/sites/2/2026/08/GettyImages-2283922022.jpg?quality=90&amp;strip=all&amp;crop=0,0,100,100" title="Protesters in Altadena hold signs supporting SB 1090, including one reading “Don’t burn us again,” during a demonstration over post-fire rebuilding and housing policy." /> <p>Altadena is characterized by its picturesque bungalows. The desire to rebuild as it was is understandable. Neil Tyler, a fire survivor supporting SB 1090, expressed concerns about developers transforming burned lots into clusters of homes that would alter the character of the community.</p> <p>The debate over SB 1090 highlights the conflict between local control and the need for increased housing supply. The metro LA area is expensive partly due to local control that has limited housing development for decades. SB 1090 could restrict the rights of property owners and hinder the construction of much-needed homes.</p> <h2>The case for rebuilding…more</h2> <p>Discussions around laws like SB 9, SB 1123, and SB 1090 may seem complex, but they reflect fundamental economic principles. When demand for housing exceeds supply, prices rise. Los Angeles has seen local zoning laws reduce allowed housing densities, contributing to the current housing crisis.</p> <p>Altadena, where the median home value is around $1.12 million, is predominantly zoned for single-family homes. State laws aim to increase housing supply by allowing more units on single lots, which could help lower housing prices.</p> <p>Reforming exclusionary zoning can also benefit fire survivors by raising land values, as parcels that can support multiple homes are worth more. For example, a lot zoned for a single-family home might sell for $500,000, while a lot allowing six smaller homes could sell for $800,000, providing financial benefits to homeowners and builders alike.</p> <p>Supporters of SB 1123 argue that it could provide financial relief to homeowners facing significant rebuilding costs. Caroline Paules, an Altadena resident and mechanical engineer, noted that building densely could help mitigate the high costs of modern fire-resistant construction.</p> <img alt="Illustrated site plan showing several small detached cottages arranged around a shared landscaped walkway, with trees, gardens, parking, and a solar-panel canopy." src="https://platform.vox.com/wp-content/uploads/sites/2/2026/08/Bluebell-Proposal-Slide-2.png?quality=90&amp;strip=all&amp;crop=0,0,100,100" title="Illustrated site plan showing several small detached cottages arranged around a shared landscaped walkway, with trees, gardens, parking, and a solar-panel canopy." /> <h2>How California’s pro-housing push swerved</h2> <p>After the fire destroyed a significant portion of Altadena’s homes, the Los Angeles County planning department promoted SB 9 and 1123 as options for rebuilding. However, as community concerns grew, the county changed its stance, voiding applications for SB 1123 developments.</p> <p>This situation reflects a broader trend of local governments resisting state housing laws. In March, LA County canceled a developer's application for SB 1123, leading to legal action from the developer.</p> <p>The fight has reached the state legislature, where Senator Sasha Renée Pérez has proposed SB 1090, which would impose a moratorium on SB 9 and SB 1123 in Altadena. The planning department did not respond to requests for comment, and local officials have been largely silent on the issue.</p> <p>While the SB 9 suspension was dropped from the bill, the moratorium on SB 1123 remains, raising concerns about its long-term implications for housing development in the area.</p> <p>Opponents of SB 1123 have framed it as a threat to local communities, portraying developers as outsiders seeking to profit from the disaster. However, supporters argue that developers are essential for addressing the housing crisis.</p> <p>Neil Tyler expressed concerns about the impact of SB 1123 on local residents, emphasizing the need for careful consideration of community needs during the rebuilding process. He noted that while some residents oppose all density increases, many support accessory dwelling units (ADUs) and other forms of development that align with local infrastructure capacity.</p> <h2>Local control clashes with regional needs</h2> <p>Only a small fraction of the homes destroyed in Altadena have been proposed for redevelopment under SB 1123. While the density allowed under this law is higher than typical for the area, it is not considered high-density by metropolitan standards.</p> <p>Opponents of new developments often cite concerns about their impact on the community, but it is important to balance these concerns with the rights of property owners and the need for increased housing supply. The emotional impact of losing low-density living is significant, but it is not a guarantee that residents are entitled to maintain that forever.</p> <p>Concerns about fire risk in Altadena are valid, given its location in a fire-prone area. However, experts suggest that density can have a complex relationship with fire risk, and building more densely in established communities may be preferable to expanding development into wildland areas.</p> <p>SB 1123 does not apply in very-high-fire-hazard areas, and local governments can reject developments that pose public health or safety threats. The ongoing debate highlights the tension between local desires for control and the broader need for housing solutions.</p> <p>Nolan Gray from California YIMBY expressed concerns that the moratorium could set a precedent for other communities seeking exemptions from state housing laws. As California continues to grapple with housing affordability, the question remains whether state leadership will support necessary reforms.</p> <p>Southern California's housing crisis underscores the need for a balance between local control and regional housing needs. The fires have already caused significant disruption, and it is crucial to ensure that housing reforms are not hindered in the process of recovery.</p>
