What this is
This site documents the design, engineering, permitting, and construction planning for rebuilding the existing garage at 1370 Wilbur Avenue as a lightweight steel superstructure with an upper storage loft and integrated south-facing solar roof.
The working direction is a steel frame constructed around the existing garage, preserving the stucco walls and slab. The structure adds nine steel columns on new pier foundations, an upper storage level, a south-facing solar array (~7.7 kW), and a low hipped rear roof cap.

Key findings so far
- Steel frame: 88 members, 2.65 tons, 138 connection nodes, 9 pier foundations
- Solar: ~5.6–6.0 kW recommended, 35° roof pitch, one 13.5 kWh battery
- Budget: $185,000–$325,000 (with GC + contingency)
- Permitting: Setbacks at 3 ft (retained garage) and 5 ft (proposed addition); coastal overlay status to be verified
- Engineering: Frame geometry coordinated; member sizing, connections, and foundations need licensed engineer
Regulatory status
The exact zoning, coastal status, setbacks, height, and parcel controls must be verified for this address. A boundary/topographic survey is the highest-priority collection item. Structural calculations in this report are preliminary unless signed and sealed by the responsible California-licensed engineer.
