Base requirements by trade
Texas TDLR and TSBPE licensing require proof of GL at license issue; GCs require more.
- Electrical (TDLR): $300K/$600K GL minimum for master licensees
- Plumbing (TSBPE): $300K GL minimum
- HVAC (TDLR): $300K/$600K GL minimum
- GC contracts: typically $1M/$2M plus AI/waiver/P&NC
The installation floater
Materials you've bought but not yet installed are not covered by GL and not covered by the owner's property policy.
- Insure at cost including your labor
- Covers theft from the jobsite and your truck
- Usually $10K–$50K limits at modest premium
Completed operations
For trades, the claim shows up years later: the water heater that flooded a house, the panel that started a fire.
- Occurrence form, never claims-made
- Do not let a carrier add a 'designated work' exclusion for your core trade
- Keep tail coverage when you retire or sell
