How do I lookup how many permits a licensed General Contractor filed in California?

[Matt A.]

I spoke with a General Contractor I hope to hire who is licensed in California. Is there some sort of website I can use to look up exactly how many permits they have filed in California? The website buildzoom.com shows around 15 permits they filed. However, this amount seems inaccurately low because they have been licensed for over 20 years. I figure they must have filed more than 15 permits in their 20+ year career?
