JMB Builders — custom homes, complete rebuilds, and whole-home renovations in Altadena, California
Altadena, California. A home begins with a clear plan. Every JMB Builders project starts by understanding the land, the structure, and the life the home needs to support.
Pre-Construction. Vision, translated into a buildable path. Scope, sequence, and budget aligned with your design team before the first piece of earth moves.
Construction. Built from the ground up. Foundation, framing, and structure carried out in a deliberate, inspectable sequence.
Detail & Finish. Precision at every layer. Stone, glazing, and roof planes resolved with the care the visible surfaces of a home deserve.
Completion. Designed to live beautifully. Built to last. A home delivered with documentation, walkthroughs, and details that hold up long after move-in.
JMB Builders. For Altadena homes with a future in mind. If your project is substantial—ground-up, a complete rebuild, or a whole-home renovation—we should talk.

Custom Homes
Ground-up homes built around the way you live.. A ground-up home is a long sequence of deliberate decisions.
Discuss a Custom Home
Complete Rebuilds
A clear path forward for properties requiring a full reconstruction.. Some properties reach a point where repair no longer makes sense: fire damage, structural failure, or a home that no longer fits the land it sits on.
Discuss a Rebuild
Whole-Home Renovations
Transformative renovations with the planning and coordination major work demands.. A whole-home renovation is not a collection of room projects—it is one connected scope in which structure, systems, layout, and finishes depend on each other.
Discuss a Renovation
ADU Construction
Detached accessory dwelling units, built with the same care as a main home.. A detached ADU is a real building — foundation, envelope, systems, finishes — just scaled down.
