https://www.seattletimes.com/seattle-news/politics/washington-state-supreme-court-upholds-seattles-first-come-first-served-law-for-renters/The Washington state Supreme Court has upheld Seattle’s first-come, first-served law for renters, believed to be the first of its kind in the country.In a unanimous written opinion published Thursday, the court rejected claims by landlords who said the groundbreaking law amounted to a regulatory taking of private property and who said it violated their due-process and free-speech rights under the state Constitution.

You also may want to look at California property tax rules whether this constitutes a ‘change in ownership’ that triggers a property tax reassessment, if that is of any concern.

Because you realize you're helping people that are constitutionally unable to help themselves, and in order for them to succeed, you're going to have to be after them with the wet wipes and powder for years, and in the end, when push comes to shove, they'll just stand there and watch their opportunities sail away, and blame you the very first chance they get.I expect people to bust their humps, do their homework and then some, tell me the truth, find reserves of resourcefulness within themselves.

Remember poor planning on your part does not constitute an emergency on the contractors part .

The city requires any "significant" modifications (restoration or modification constituting 50% of the value) to elevate the house and secure to a new concrete foundation. 

I'm painting with some broad brush strokes here...but basically the City/County/State can't deny you the use or rights to your property without just compensation (your constitutional property rights).

Occupancy by a roommate of an owner who occupies the unit as such owner's primary residence shall also not constitute leasing".From my interpretation, if I have people living with me in my spare rooms, they would be considered roommates since I am also occupying the unit. 

Would this constitute as living for the full year?

It's also important to start studying your market so you know what constitutes a good deal or not.
