We're fully negotiated and ready to sign the purchase and sale TODAY, but the current owner(s) signed a quitclaim a little over a month ago to clarify ownership and my lender just indicated that it could be a problem (they are researching now, no official word yet). 

The following is a brief summary of the law from a property management website - https://gpmsf.com/how-to-handle-roommate-changes/"Occupancy Numbers in San FranciscoIn 2015, the Board of Supervisors passed the Jane Kim legislation, which basically says landlords have to allow as many occupants in an apartment that health and safety standards will support.

@Lakeither Garner so is the issue that you and the seller want to complete the sale before the lot is officially subdivided?

It has some hurdles in the zoning process with getting water/sewer extended but I think in the long-term it is feasible with the discussions I have had with local officials. 

Having rented till now, I find myself in a position where I must buy something to accommodate the health needs of a loved one.

It's official.

The phones have officially stopped ringing.So.... how do I get physical visibility from the road without violating city ordinances, or asking random people to put my signs in their yard(which I wont do).

How has that first official rental been going now that you moved out?

It's probably going to cost less than the deductible on any insurance claim and I don't think it would qualify for insurance, anyway.Unless it's a health hazard, I would wait until the renter vacates so you can work unimpeded.

Being under contract I am doing due diligence and have an opportunity to submit the Request for Repairs asking for the seller to give on some of the larger health and safety things I'm finding need to be done before I move into the house after I conducted an inspection and uncovered lots of baggage associated with an insurance claim for a fire at the property.My questions: - Does anyone have experience negotiating at this point in a seller's market when bigger ticket health and safety items have come back on the inspection report?
