Des Moines Subdivision Builder — Tornado Damage, Per-Occurrence Question
A May tornado hit a Des Moines subdivision development mid-construction across 14 lots. The GC assumed the builder's risk deductible was per-property — meaning each lot would carry its own deductible, distributed across 14 small claims. The deductible was actually per-occurrence — one deductible covered the entire event. The math made the difference between absorbable and catastrophic.
Pulled the builder's risk policy and confirmed the per-occurrence deductible structure. Coordinated the claim across all 14 lots as a single event. Walked the GC through how the deductible structure interacts with multi-property tornado exposure for next year's renewal.
The single per-occurrence deductible let the claim resolve cleanly across all 14 lots. Next renewal restructured to a per-property deductible to reduce exposure on multi-lot tornado events. Iowa contractors running multi-lot subdivision work need to know which deductible structure they actually have.
