SB 1090 Is Now Law, but New Investigation Finds 200 to 300 Altadena Structures May Already Be in the Pipeline

ALTADENA, CA | October 4, 2026

California's new law gives Altadena a temporary cooling-off period from one controversial high-density development pathway, but a new investigation finds that dozens of projects representing hundreds of new structures may already have entered the development pipeline before the protection took effect.

Inside Climate News published a detailed investigation October 4 examining development activity in Altadena during the Eaton Fire recovery.

The investigation found that more than 60 housing proposals representing approximately 200 to 300 new structures had already been approved in Altadena before Senate Bill 1090 took effect October 1.

That matters because SB 1090 does not retroactively stop qualifying projects submitted before its effective date.

THE NEW NUMBERS

60+: Housing proposals reported as already approved.

200 to 300: Estimated structures represented by those proposals.

3,600+: Building permits issued within the Eaton Fire burn scar between February 2025 and late September 2026.

Just under 200: Destroyed housing units reported as fully rebuilt in the latest County permitting data.

The permit and completed-home figures should not be treated as a one-to-one comparison. A single reconstruction project can require multiple permits.

But the new reporting provides an important look at the different development and rebuilding activity occurring simultaneously across Altadena.

What SB 1090 Changed

Governor Gavin Newsom signed SB 1090, the Keep Altadena Land in Altadena Hands Act, on September 30.

The urgency legislation took effect October 1.

The final law temporarily limits specified SB 1123 ministerial subdivision and housing-development approval requirements in Altadena during the Eaton Fire recovery period.

It is intended to give the community additional time to rebuild before one particular state pathway for substantially denser development can again be broadly used.

But the Law Is Not Retroactive

THE CRITICAL DATE IS OCTOBER 1, 2026

SB 1090 protects Altadena from specified new SB 1123 applications during the temporary statutory period.

It does not automatically cancel qualifying development proposals submitted before October 1.

That means some projects already in the pipeline can continue even though the new law is now in effect.

More Than 60 Proposals Were Already Approved

Inside Climate News reports that Los Angeles County informed Altadena Town Council members of more than 60 housing proposals permitted through streamlined state-law processes.

Altadena Town Council member Nic Arnzen told the publication those projects represent approximately 200 to 300 structures.

The publication reports that the vast majority of the proposals involve developers from outside the community.

It also reports that projects are connected to more than 100 different companies, some located outside California and some with reported ties to private equity.

Those findings do not by themselves establish wrongdoing by a developer. They do demonstrate the scale of outside development activity occurring while thousands of Eaton Fire survivors are still trying to return home.

SB 9 Remains Available

Another important point concerns the final version of SB 1090.

Earlier versions contemplated broader restrictions.

The final law focuses on SB 1123.

SB 9 remains available for qualifying projects.

That means the new law does not create a complete moratorium on residential subdivision or additional housing development throughout Altadena.

WHAT SB 1090 DOES

Temporarily restricts specified SB 1123 streamlined development pathways in Altadena.

WHAT IT DOES NOT DO

It does not automatically cancel qualifying projects submitted before October 1, and it does not suspend SB 9.

The Rebuilding Numbers Show Why Residents Are Concerned

The investigation reports that just under 200 of the nearly 7,000 housing units destroyed by the Eaton Fire have been fully rebuilt according to the latest Los Angeles County permitting data.

At the same time, more than 3,600 building permits of various types have been issued within the Eaton Fire burn scar since February 2025.

Many survivors remain caught between insurance settlements, Southern California Edison litigation, rebuilding costs, financing and the permitting process.

That timing difference is fueling concern among residents who see outside development moving forward while their own return remains uncertain.

There Is Another Side to the Debate

Supporters of California's housing streamlining laws argue that additional housing and lot-splitting options can help property owners who cannot afford to rebuild a single-family home under current construction costs.

California YIMBY has argued that limiting those options could unintentionally increase financial pressure on underinsured homeowners and potentially force some residents to sell.

Altadena community advocates supporting SB 1090 argue that the final legislation represents a compromise because SB 9 was removed from the restrictions and the SB 1123 pause is temporary.

The debate therefore is not simply housing versus no housing. It concerns how, where and by whom additional housing should be developed while a disaster-damaged community is still rebuilding.

There Is an Exception for Community-Based Housing

The final SB 1090 includes an exception intended to allow qualifying community land trusts and cooperatives to continue using the SB 1123 pathway for accessible and affordable housing.

That provision is designed to distinguish community-based efforts to return displaced residents from speculative redevelopment.

More Legislation May Be Possible

State Senator Sasha Renée Pérez told Inside Climate News that she is not ruling out additional legislation or resources intended to protect community members from speculative activity during Altadena's recovery.

That is worth watching because SB 1090 is now operating in a real-world environment where substantial development activity was already underway before the law became effective.

WHAT THIS MEANS FOR EATON FIRE SURVIVORS

SB 1090 is meaningful protection, but it is not a reset button.

Projects already submitted before October 1 may continue under the rules that existed before the new law.

SB 9 remains available for qualifying projects.

Survivors considering whether to rebuild, sell or restructure their property should understand exactly which development rules apply to their parcel.

The next major question is what happens to the hundreds of structures that may already be in the development pipeline.

The Larger Eaton Fire Watch

Our October 4 review found no newly enacted successor or replacement for SB 492 and no new special-session action involving utility wildfire liability.

No new Eaton Fire damages cap, Southern California Edison liability shield or restriction eliminating insurers' existing subrogation rights was identified.

Southern California Edison's November 30 deadline for new claims through its Wildfire Recovery Compensation Program remains unchanged.

Altadena Talks Foundation will continue monitoring SB 1090 implementation, Eaton Fire rebuilding, Southern California Edison liability, wildfire legislation, litigation, insurance and federal recovery assistance.

Keep Hope Alive.
