About Home Additions in Los Angeles

What we resolve before drawings begin.

  • 01

    Existing foundation capacity

    Second-story additions often require new piers or a strengthened perimeter foundation. We commission a structural engineer during feasibility, not after permit.

  • 02

    Hillside and grading rules

    Hillside lots in LA carry export-of-fill limits and additional structural review. We confirm during feasibility.

  • 03

    Tying the addition into existing finish

    Stucco, siding, and roof transitions are where amateur work shows. We detail these before the addition framing closes up.
