If the squatter is a former tenant, I would suggest you contact an attorney as you will likely need to evict this party .

Nolo Press has a series of great books on "landlording" and the eviction process. A "squatter" though is an interesting term. Is he a left over from the Charlie Manson clan? Those hills up there in San Diego have all sorts of strange folks wandering about! A real sharp eviction attorney will cost you around $1500.00 for everything and will be well worth it.
And yes, be glad this didn't happen in San Francisco--they'd own the property in a couple of years!
I think the best answer for this question is PREVENTION, through knowledge and wisdom. I THANK GOD for sites like this, I was able to nip a squatter in the bud while she tried to move in, refused to pay rent, made up numerous excuses, tried to plot our (paying) roommates against each other, stole from us, used us, and partied around L.A. while we worked throughout the summer to pay our rent.
Besides the helpful sites that share experiences, legalities, ad advice, I found that reading the popular Squatter sites are helpful as well. They gave me incite to Squatter codes, plans, angles, and true intentions. Check out the squatter site below.
Squatters are modern day BUMS, who use the "homeless" excuse to lure victims and get stuff for free. Squatter-bums think they are too good to work, complain about society, yet they expect society to take care of them. They use excuses that they are anarchists, advisers, artists, genius', while they live off of societies working class. Many of them bag on hippies, yet they live the life of modern-day hippy bums. Lazy bums.
Good luck to everyone who has one of these infested vermin trying to leech off of you. We are still trying to get her stink out of our home. I am not kidding --- she refused to wear deodorant, take out her trash, or buy athletes foot medication. Good riddance.
I do not know the answer to your question, but you should see the movie Pacific Heights with Michael Keaton. It is about a landlord in San Francisco that cannot get a bad, non paying renter to get out. It is pretty good, yet disturbing.
Good luck on this one, squatters suck. Let us know how it turns out.
Speaking of squatters, checkout this article on a Colorado couple that lost a million dollars worth of land to some squatters a couple of months ago:
There is a reason that movie was filmed in San Francisco. The politics here are crazy. Ive heard of stories where homeless people "move" onto peoples balconies, and it takes forever to get them off because their shopping cart junk they move in is considered "private property".
Rebecca...you are lucky you are not in San Francisco with this problem or you would be screwed.
