Property and Land

Boulder County’s Property and Land Services provide detailed information on property records, taxation, land‑use planning, zoning, and building requirements. These programs support informed decision‑making for residents, property owners, and developers, while also promoting responsible growth, environmental stewardship, and practices that strengthen the county’s resilience to wildfires.

Assessor’s Office

The Boulder County Assessor’s Office updates property values every two years for more than 120,000 properties, totaling nearly $50 billion in market value. To complete this work, the office uses tools such as geographic information systems (GIS) and mass‑appraisal methods to analyze property data. Staff identify and record key details about each property and use that information to determine fair and accurate property values.
