The Complete Guide to Rebuilding After the Eaton Fire (Updated 2026)
(Updated May 2026 — 16 Months In)
Sixteen months ago, the Eaton Fire changed Altadena overnight.
In the weeks and months that followed, we sat across from dozens of families at kitchen tables, on cleared lots, and in county offices — and we learned a lot. Not just about permits and timelines, but about what this process actually looks like when it meets real people, real insurance adjusters, and a real backlog at LA County.
This guide is the result of that experience.
We are ATP Development & Construction, a Pasadena-based design-build firm that has been working with Altadena fire rebuild homeowners since the early weeks of recovery. We are not writing this from a distance. We have been in these neighborhoods, at these job sites, and in these permit offices throughout the past year and a half.
What follows is the most honest, current picture we can give you of the Eaton Fire rebuild process — step by step, with real timelines, real watch-outs, and what we have learned that was not in any guide published in January 2025.
Step 1 — Debris Removal and Lot Clearance
Where most Altadena properties stand today: For the majority of fire-affected parcels, Phase 1 debris removal (hazardous materials, managed by FEMA and the Army Corps) was completed in the spring and summer of 2025. Phase 2 structural debris removal — either through the government program or by private contractor — has now been completed on most participating properties.
If your lot is not yet cleared, you are not behind — but this is the step to address first. LA County requires a final clearance certification confirming the property is safe for construction before any permits can be issued. If you opted out of the government program and need to complete private debris removal, we can connect you with the right contractors and walk you through the clearance documentation.
If your lot is already cleared, you have the single most important prerequisite in place. You are ready to move.
"Go local — or use your resources. Organizations like CORE and the U.S. Army Corps of Engineers were on the ground here from the start. But whatever you do, make sure you have someone who can actually show up in person. This is not the situation to be managed from behind a screen."
— Sergio Alvarez, Founder, ATP Development & Construction
Step 2 — Site Visit and Project Evaluation
This is where we get on the ground together.
We review your lot conditions, any salvageable foundation, setback and zoning requirements, and your full buildable footprint. If you have a Scope of Loss from your insurance adjuster, we walk through it with you — and we have become very good at spotting the gaps between what an adjuster assessed and what it actually costs to rebuild in Altadena in 2026.
What 16 months has taught us on this step: The homeowners who are furthest along right now are the ones who started this conversation early — often before their insurance was finalized. The homeowners who waited for a final insurance number before calling anyone are, in many cases, still waiting.
You do not need to have your final insurance settlement to start. You need a cleared lot and a phone call.
Step 3 — Architecture and Engineering
This is where your home takes shape on paper — and where the design-build advantage becomes most visible.
ATP provides full architectural and structural engineering services under one roof. Our architects work with you on the design: rebuild exactly as it was, modify the layout, modernize the aesthetic, or take this moment to build the home you always wanted. Our structural engineers work in parallel on all California code requirements, load specs, foundation design, and any hillside or fire-zone specifics that apply to your property.
What we have seen in practice: Many homeowners initially want to rebuild "exactly like it was." After the design conversation, roughly half make meaningful changes — an open floor plan, an added bedroom, a garage conversion to living space. This is completely valid and often adds significant long-term value. The key is deciding early, because mid-design changes extend timelines.
We provide 3D renderings before anything is finalized. You see the home before it exists.
Realistic timeline for architecture and engineering: 2 to 3 months from project start to permit-ready plans.
"I've been part of this community for almost 40 years. My kids grew up here. When this happened, people I knew started calling me — not as a contractor, but just for a second opinion, for clarity, for someone to tell them what step to even take next. I don't want anyone stuck in that daze. Whether you end up working with ATP or not — call us. We are an open resource. Second opinions, help with resources, questions about where you stand in the process. We are here. Our goal is to see Altadena rebuilt stronger than it was before."

Step 4 — Permitting and Plan Check
Permitting is the phase that has surprised homeowners most — and after 16 months, we can tell you exactly why.
Here is what the process looks like for an Altadena fire rebuild in 2026:
LA County Planning Department reviews for zoning compliance, site plan accuracy, setbacks, height restrictions, and "like for like" comparisons against the original structure. This typically takes 9 to 14 business days for initial review.
LA County Building and Safety conducts the structural and code review, responds with plan check corrections, and issues the permit — called an RTI (Ready to Issue) — once corrections are cleared. This stage runs 4 to 8 weeks, depending on correction volume.
What we have learned after going through this process repeatedly: The correction round is almost never one-and-done. Plan check corrections are normal — they are not a sign something is wrong. The projects that move fastest are the ones with accurate, complete submittals from the start. That is a direct result of having experienced architects and engineers who know what county reviewers are looking for.
Realistic total permitting timeline: 2 to 6 months. Some projects have moved faster. A few have taken longer. Hillside properties, larger footprints, and significant design changes from the original structure tend to take more time.
We manage this entire process. We submit, track, respond to corrections, and follow up with county departments on your behalf. You do not touch this.
Step 5 — Pre-Construction Coordination
Once permits are issued, we move into the coordination phase that most homeowners never see — and the one that determines how smoothly construction runs.
This includes finalizing all material selections, scheduling subcontractors, ordering long-lead items (windows, doors, custom materials), and building a sequenced construction plan with milestone dates. Your dedicated ATP project manager is assigned at this stage and becomes your single point of contact for everything that follows.
One thing worth knowing: Material lead times have been a real factor in the Altadena rebuild timeline. Certain windows, HVAC systems, and engineered lumber have run 8 to 14 weeks out. We front-load these orders early specifically to avoid construction stalls down the road.
Step 6 — Construction
Construction follows a structured sequence: foundation → framing → mechanical, electrical, and plumbing → insulation → drywall → finishes → punch list.
City inspections occur throughout: foundation, framing, rough MEP, insulation, and final building inspection. For fire rebuild properties in designated hazard zones, additional wildfire code inspections are required. ATP schedules and manages every one of these.
Realistic construction timeline: 6 to 10 months, depending on square footage, design complexity, and inspection scheduling. For larger or more complex builds, plan closer to 10 to 12.
Step 7 — Final Inspections and Certificate of Occupancy
The final phase is the one every family is working toward: passing final inspections and receiving the Certificate of Occupancy (CO) — the official confirmation your home meets all codes and is approved for you to move back in.
Before city inspectors arrive, we conduct a thorough punch list walkthrough of the entire home to identify and resolve anything outstanding. Once the CO is issued, the rebuild is complete.
Total timeline from cleared lot to move-in: approximately 12 to 20 months. We are giving you a slightly wider range than some guides because we have now seen this process in full. Projects at the shorter end have exceptional insurance coordination and straightforward designs. Projects at the longer end involve complex sites, design changes, or extended permitting. Most Altadena projects we have worked on fall in the 14 to 18 month window.
What ATP Does — From Start to Finish
When you work with ATP, you are not hiring a contractor and then separately hiring an architect and then separately managing a permit expediter. One team handles all of it.
- Full custom architectural design
- Structural engineering
- Permitting and plan check management
- Pre-construction coordination
- Construction from foundation to finishes
- All city inspections and final CO
One team. One point of contact. One process — from the cleared lot to the day you walk back through your front door.
Where Are We in the Altadena Recovery?
We want to be honest with you about where things stand.
The families who started their rebuild process in the first half of 2025 are, in many cases, already in construction or approaching final inspections. The families who are just starting now are not too late — but every month matters. Permitting queues are not shrinking, and demand on quality contractors continues to be high.
If you have been waiting — for insurance, for clarity, for the right moment — this is the moment we would point to.
Ready to Start? Here's Your Next Step.
We offer a free consultation to every Altadena fire rebuild homeowner. No commitment, no pressure, no requirement to have your insurance finalized.
Most of our rebuild clients came to us in the middle of the process — some before permits, some still in debris removal, some just trying to understand what the process even looks like.
We are 10 to 15 minutes from every Altadena job site. We have been on the ground since January 2025. And we are ready when you are.
