The Transition Gap: The Most Dangerous Moment in Construction Finance
⚠️ Critical Coverage Gap Warning
Builder's risk coverage terminates when the project reaches substantial completion — typically when a certificate of occupancy is issued or the owner takes possession. Commercial property coverage needs to be active before this transition happens.
A completed building sitting without either builder's risk (which has expired) or commercial property (which hasn't been bound yet) is completely uninsured. A fire, windstorm, or vandalism event during this gap can produce a total uninsured loss.
During construction
Builder's risk is active. The policy covers the structure, materials on site, and construction period losses.
Approaching completion
Notify your insurance broker at least 30 days before projected completion. Begin binding commercial property coverage.
Substantial completion / CO issuance
Builder's risk terminates. Commercial property must be in force by this date. Do not leave a gap.
Building occupied and in use
Commercial property provides ongoing coverage for the completed building, tenant improvements, and business operations.
What Builder's Risk Actually Covers
✅ Covered
- • Structure under construction
- • Building materials stored on site
- • Temporary structures (formwork, scaffolding — check policy)
- • Loss in transit (materials being delivered)
- • Soft costs (architectural fees, permits — with endorsement)
- • Flood and earthquake (with endorsements)
- • Fire, wind, hail, theft, vandalism, collapse
❌ Not Covered
- • Contractor tools and equipment
- • Completed portions after CO issued
- • Normal wear and faulty workmanship
- • Earth movement / flood (without endorsement)
- • Employee theft (separate fidelity bond)
- • Third-party liability (need GL for that)
- • Delay in completion / lost income (soft costs endorsement needed)
