## Building Permits — Key Limitation
Hawaii County uses Tyler Technologies EnerGov (EPIC system). **No public REST API for bulk building permit data.** 
Planning permits (SMA, use, variance) ARE queryable via gis.hawaiicounty.gov above.

## Token-Gated (not publicly accessible)
- Civil Defense data
- Real Property Tax (RPT) division data  
- Long Range Planning (LRP)
- OHCD (housing)
- Broadband coverage layer exists but token-required
- Hele-On bus routes/stops (GTFS may be available separately)
- Water Supply DWS (dashboard only, no exposed feature service)
