California State Property and Lease Inventory

California's Statewide Property Inventory tracks land and structures owned or leased by the state, as well as property leased to the private sector. The inventory was established in 1988, with lease data added in 2004, and is updated annually by state agencies. Data is available in multiple formats including CSV, KML, and GeoJSON.

Use Cases

• Analyze state-owned land and leased property locations for asset management planning using geographic data formats like KML and GeoJSON.
• Track the annual update cycle of state property and lease records to monitor changes in government asset portfolios.
• Examine the distribution of property leased to the private sector versus state-leased assets for fiscal analysis.

Strengths

• Data collection is mandated by state legislation, ensuring a systematic and official source.
• Inventory has been maintained since 1988, with lease records added in 2004, providing a multi-decade perspective.
• Data is available in multiple formats including tabular (CSV) and spatial (KML, GeoJSON, ArcGIS REST API).

Limitations

• Specific column names, row counts, and data volume are unknown, limiting assessment of granularity and scale.
• Annual update frequency may not capture real-time changes in property status or lease agreements.
