I think the thing I'd be trying to work in a project like this is how they define attached or detached and if there is any room for creativity to get you something like a DADU while still complying. 

I went to the county constable's office today who handles that area and they suggested since they aren't the owners or residents to put a vacate notice on the door and if they don't comply I could charge them with trespassing.

Unless you're suggesting to post the notice as sort of a scare tactic to try to get them to comply. to me actually following through makes no sense.

It is very common for landlords to not comply with board rulings ordering payments to tenants or board fines.The only penalty a landlord would face for non payment  would be the denial of their right to file any future applications with the board.

There is everything from ultra luxury full service like the Plaza in New York all the way down to the limited service "bottom of the brand" Knights Inn or the mom and pops that are run by live-in owners.If you purchase a branded or "flagged" property, you will need to comply with the franchise agreement.

I have even found some that comply with the 1% rule.    

Does the home comply with state law…smoke detectors, water heater safety straps, radon tested, carbon monoxide detectors.Has the home been inspected for mold?

Hey James, It may be tough to have a seller to agree to a lead test this late in the game, and they do not have to comply.

I have had participants go down to a 0% subsidy - meaning they paid 100% of their rent, but as long as they complied they got to stay in the program in the event they had a change of income.  

That is the question.My husband was the handyman (well we had a work crew, but hubby was the ultimate handyman, perfectionist to an annoying fault...even to this day everything has to be perfect)  I on the other hand, was the Zoo Keeper, oops I mean I took care of the nasty stuff, like tenant complaints, accounting, court scenes, making the tenants comply to their lease agreement.
