Well I am very definitely along with my crew helping to maintain #4. As to the three shotgun houses, you're right.. they probably are beyond saving ( which makes me wonder.. why whoever went to the trouble of moving them ,only to let them sit and rot. )
At this point , the ONLY thing the City has done for #4 is haul the curbside yard debris myself and my volunteers place, to the street. They pay their MCCD people to come post a notice of all the violations of the building on a fence, where no one but the vagrants and vandals will see it. the OWNER , turns out , IS paying a third party company to secure the building. By nightfall the idiots are back undoing that. We are doing our best to keep up with it and keep the place looking halfway decent.
You wouldn't want a supposedly , broke City footing the tab for demolishing these places.. It would be quite costly, and way smarter to mothball them until a use can be identified. But the City demonstrates the exact opposite and demolishes them without any consideration. The wrong people are in charge.
