General Building Contractors in California: market size and renewals

Where the competition is

Licence counts by county, densest first. Use it to see how contested a patch already is before you spend money marketing into it, or to find the countys where the register is thin.

Renewal pipeline

Licences with an expiry date inside each window, counted from the board file. A licence that has already lapsed or been suspended is excluded, so these are people who currently hold a valid licence and have a renewal coming.

New general building contractors per year

How many general building contractors currently on the register were first issued in each year. Older years thin out as licences lapse and drop off the file, so read this as the surviving cohort, not as the number issued at the time.
