Bridge housing is a temporary housing model with service-enriched programs aimed at quickly removing homeless Angelenos from the streets and assisting them in rebuilding their lives. The housing comes in three forms: bridge tents, mobile homes, and permanent single-family homes. They are usually constructed out of a frame with a canvas cover. These structures can be taken down and moved if necessary. They offer an easy-to-set up living environment and often include kitchen facilities and storage space. Many have bathrooms with showers and some even have laundry rooms. Bridge tents are generally about 8 feet long by 6 feet wide and can weigh up to 1500 pounds. They are easily set up in a matter of hours and can be taken down in less than 30 minutes. Because they are not designed for permanence, they do not include any internal walls or doors; instead there are only curtains for privacy. The tent bodies are made of aluminum tubing with polypropylene fabric covering. There are several different brands of bridge tents available on the market today, each brand trying to provide users with what they need in terms of quality and price. Mobile homes are similar to bridge tents in that they are not intended to last more than 10 years.
