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.

At first I was annoyed with this, but it's a good safety net for the seller.

Site safety?

You need experience and knowledge in; soil suitability, EPA guidelines, Department of Transportation requirements for highway/road access, road development, zoning and permitting, accurate bidding, utility management, life/safety requirement and so forth.  

my husband is a bit hesitant because we have two young kids and worry about their safety

A licensed electrician might have gotten at least an Electrical Safety Authority permission / certificate to conduct the work.

Also, this not reflecting the owner occupied flight out of Philadelphia to the suburban market counties and southern new jersey communities since there is a shift in work enviroment's and neighborhood safety in the urban neighborhoods.

No, there're safety benefits, and it's a legal requirement.

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?
