Altadena is our home. ATP Development & Construction has worked in these neighborhoods for years. When the fires came, we did not have to decide whether to show up. We were already here.
We are not a national firm that relocated after the disaster. We are your neighbors, and we understand that what you are facing right now is not just a construction project. It is your home, your history, and your future.

We offer full in-house capability from the first meeting to the day you move back in. Architecture, structural engineering, permitting, and construction are all handled by our team. When you work with ATP, you are not managing four separate vendors. You are working with one firm that is accountable for the whole process.
✅ In-House Architecture & Engineering
Your rebuild plans are designed and stamped by our in-house team. No hand-offs to outside architects.
✅ Permitting & Expediting
We know the Los Angeles County permitting process. We submit, we manage, and we follow up until approval.
✅ Insurance Support
We work alongside your insurance adjuster and help document what is needed to move your claim forward.
✅ Full Construction
When plans are approved, our licensed construction team builds. We do not sub out the core work.
Already have approved plans? Start at Step 4. Need help from the beginning? Start at Step 1. ATP is here to support your rebuild at whatever stage you are in. You do not have to hire us for everything. Just hire us for what you need. Let us do the heavy lifting.
We meet to understand your situation, your insurance status, and what you need to move forward. No commitment required.
Our design team produces a complete set of permit-ready plans for your rebuild.
We submit to Los Angeles County and manage the review process from submission to approval.
Once approved, our licensed construction team begins the build. You have one contact for the entire project.
We walk the project to completion with you and do not close out until the work is done right.
