“In VHFHSZ fire zones — which cover most of the Santa Monica Mountains, the Verdugo Hills, and the western Valley — the exterior envelope must meet specific fire-hardening requirements for any permitted work: tempered windows, no wood siding, 1/8-inch mesh vents, non-combustible fascia and trim. These requirements apply to the whole structure, not just the area being remodeled.”
Ask for a 3D exterior rendering before approving any exterior design concept. Even a simple SketchUp or Revit rendering lets you see how the material palette, window proportions, and entry design interact as a composition. Changes in a rendering cost nothing; changes in built work cost real money.
