Patio Cover & Carport Engineering in San Marcos: Local Conditions That Matter
San Marcos is in a moderate seismic zone. Seismic design required. Attached patio covers are structural additions to your home — they carry wind, seismic, and sometimes roof loads, and their posts and footings sit in the same soils that challenge San Marcos foundations.
