Two homes on one Altadena lot under California's SB 9 — a 2,200 sq ft main house and an 870 sq ft second home, from entitlement through finished build.

Pursuant to California's SB 9, the Fair Oaks lot was developed with two independent homes — a 2,200 sq ft main house and an 870 sq ft second home — delivering multi-generational living and long-term rental flexibility on a single parcel.
Phillips Group led the project from first sketch through final walkthrough — coordinating architecture and interior design, structural engineering, city permitting, and construction. Processing the SB 9 entitlement is a specialty trade that can cost $50,000–$80,000 on its own; managing it alongside design and construction kept the two-home build on one predictable schedule.
Every Phillips Group project moves through the same four phases — with one point of contact accountable start to finish.
Site study, floor plans, and elevations for both homes — plus interior direction and material selections locked before a shovel hits the ground.
Structural engineering, Title-24 energy compliance, and the full SB 9 entitlement and city permitting process — managed so timelines stay predictable.
Foundation, framing, mechanical/electrical/plumbing, and the exterior envelope for two structures — managed and closely supervised on a single coordinated schedule.
Cabinetry, tile, lighting, landscape and hardscape, final inspections, and a clean handover of a move-in-ready home and income-ready ADU.
Whether it's a custom home, an ADU, or both on one lot — Phillips Group can take it from first drawing to final walkthrough.
