Where to find Roseville open data

Roseville publishes datasets and APIs through its official open data portal and department pages. Start at the city portal to search catalogs, view dataset metadata, and find REST or API endpoints for downloads and live queries. Many datasets include schema, update frequency, and contact information on their dataset page.Open Data Portal[1]

Use the portal search and dataset tags to find planning, public works, and parking datasets quickly.

Common dataset categories

  • Planning and zoning datasets (parcels, zoning designations, permits).
  • Public works and construction data (projects, permits, closures).
  • Parking, traffic incidents, and curb-use inventories.
  • Inspections, code enforcement records, and compliance logs.

How to access APIs

Most datasets expose REST endpoints and query parameters for filtering and paging. Typical steps are: locate the dataset page on the portal, copy the API endpoint or “Export” link, test queries with filters and pagination, and follow rate limits or API key instructions if published. If a dataset lacks an API or you need a large extract, submit a public records request to the City Clerk.Public Records[2]

If an API key or license is required, the dataset page will list that requirement.
