Ok, so I have been told by the old owner of my business that you do not need a contractors license to install irrigation. He told me that you only need a contractors license if you are giving a set bid price. Now, I have other people telling me different. The old owner has a current contractors license and has been doing sprinklers for 40 years and trained me as well. Now I am looking into doing a sprinkler system for a customer and some people on here are telling me I can't do it legally. I have a liability insurance policy with 2 million aggregate coverage, workers compensation, business licensing...but no contractors license. I understand that if this were true it would only be to protect the customer from shoddy installation amongst other things, but as someone as myself who does nothing under the table...thats not my intent. I have done many controllers, whole valve installation assemblies and assisted in 4 sprinkler jobs. Not that any of this matters if I truly have to have a contractors license period. So...do I? I'm in California btw.
