In the United States, all land is presumed to belong to the government unless an individual or entity holds title to it. So, a person cannot simply settle comfortably on some land, or park a vehicle there, and try to get an address for it. Getting a home address begins with the government’s making the land available for private residence. Then a real estate developer, or whoever has bought the land from the government, gets the first title to it and records his title at the deeds office, usually a component of the county government. If you need to find out who owns a piece of land, you are allowed to search for the deed because it is a public record held at the deeds office.
Title is legal ownership of land. A deed is the document showing that someone has title to a piece of land. The deeds office identifies pieces of land by giving them block and lot numbers, known as the legal address. When the landowner applies for local permits to build structures on that land, a street address (the address used by the postal service) is assigned to it. If a landowner opts to make a trailer park on his land, then his building permit will establish street addresses for the separate spaces in the trailer park.

In California, IF YOU NEED TO GET INTO A SHELTER YOU HAVE TO GO IN PERSON TO THE LOCAL DEPARTMENT OF SOCIAL SERVICES OFFICE. YOU MUST GO IN PERSON. Many people think they can either call a shelter or walk in and get a bed. This is a huge misperception. The system is simply (sadly) not designed to work this way. Probably because it is not supposed to be used as any sort of “option” for those who have other choices and because a paper trail must be diligently kept for funding purposes (which cannot be done by shelter staff). If you phone a government funded shelter and ask if there are open beds, you will always be told no. Every single time. Even if it is empty. You must go to the local Social Services Office and request a voucher, which is a fairly easy process. With a voucher, you’ll be given a bed at a shelter and buss tokens to get there.
At the year round shelter I was sent to, all residents stay in a private from for 30 days, and then are transfered to a 3 or 4 person room. They served 3 meals a day. The shelter staff assists residents in finding programs to help them apply for SSI, SSDI, Section 8 and/or find other low income housing. I lived in the part for single residents, but there was an entire community for families as well.
Obviously it was the worst experience of my life, but it’s over. I think that’s the important part… That at some point, the homeless experience ends for everyone. That it doesn’t crush them.
