Ontario is in a seismic zone. Seismic design required per building code. Inland Empire soils include sandy loam and alluvium. Foundation assessment important. Decks in Ontario fail from ledger attachment, post corrosion, and undersized framing — and California's exterior elevated element rules tightened after balcony collapses statewide. Our designs address the loads and deterioration risks your local climate actually produces.
