About this dataset
Detailed information about each residential or commercial building permit processed by, and under the jurisdiction of, Marin County. Data is updated daily and covers the time period beginning January 1, 2014 until the present.
Simpler permits, which are issued on demand, have issued dates but do not have received dates nor plan approval dates.
More complex permits that involve permit inspections, and often involve building plans that must be approved, have a received date, an issued date and often a plan approval date. The received date is the date a permit application is received. The issued date is the date the permit has been fully approved and issued, and may be many weeks or months after the received date.
The related Building Permit Inspection dataset has inspections for building permits. It has a common data column, Permit Tracking ID. Advanced analysis tools can be used to analyze both permits and their inspections.
