"9.Floating Home Residency Law Inapplicable...
10.No Residential Tenancy Created."
Keep in mind that even though Cali tends to do things differently from the rest of the US, and even the federal courts in Cali tend to differ from the federal courts in the rest of the US, when a contract
tries to set aside statutory rights, or run counter to them, even in Cali the contract
may be thrown out, because statutory rights generally can't be destroyed by contract.
I can sign a contract with you, selling you my vote for twenty bucks. But that won't change the fact that selling my vote is illegal, by statute. Whatever the local (city, state, county) housing and tenancy laws are, they are. A contract? Doesn't count unless the statutes allow for it to do so.
A tenant on a boat? Governed by housing laws? Well, they've bio-engineered flying pigs too, or so I've heard.<G> As the contract refers to a "floating home residency law" there might be
some statute that needs looking at.
In some venues, simply bringing an action in housing court will result in a temporary restraining order, barring evictions for 3-6 months until the action is heard in the court. So there's one option, bring the landlord (waterlord?) to housing court, and at least get the action delayed to buy some time. Or, ask them for a delay so you won't have to compel it. And in the meantime, research
that "floating home residency law".
