Former neighbors of mine got in trouble for having friends stay in tents in their backyard for a while.
Granted, they were meth-heads, but what they got in a lot of trouble for was the tents not the noise/drugs. If you're running a "business" based on tents in your backyard, you could attract the wrong kind of attention, too.
Check out the Tech and Beer house too then - they had a BBQ last weekend, very nice to meet some startup people there. (The BBQ was posted on HN, I don't think the house itself has a website)
Technically, there are places you can camp in California for cheaper than $10 a night. But this does seem much easier and certainly more entertaining. ;-)
