If you're a sole proprietor who comes to students' homes, you're going to pass every legal test of "physical presence in California".
Note that Lambda School's lawyer interpreted the law the same way you'd like to -- Lambda School doesn't have a physical presence in California because it doesn't operate any classrooms. But the state felt differently.
And the state is pretty unambiguously correct on this point -- Lambda School is apparently incorporated in California as Lambda Inc. with a business address of 921 Crescent Court, San Ramon, CA 94582.
> Lambda, Inc. of California, doing business as Lambda School, operates as a school. The School offers course such as computer science, software engineering, machine learning, web developing, and java script learning programs. Lambda School serves clients in the State of California.

So far so good.
The address does appear to be wrong, judging by the entry for "LAMBDA INC. WHICH WILL DO BUSINESS IN CALIFORNIA AS LAMBDA SCHOOL" at https://businesssearch.sos.ca.gov/
But,
> Entity Address:
> 5820 STONERIDGE MALL RD STE 212 PLEASANTON CA 94588
sure seems to suggest that you've got a physical presence in California.
I was under the impression that extant businesses have some value purely for their history of being extant businesses, and are sometimes bought and sold for that reason, so it didn't seem impossible that Lambda School was technically the reimagining of some now-dead shell corporation founded in 1983.
Bloomberg's phone number for Lambda School appears to be right, or at least appears to be a phone number once controlled by an Austen Allred in his capacity as executive officer of a company in Utah. Now I'm pretty curious where the Bloomberg information comes from.

Fascinatingly, they seem to have been incorporated in 1983.
