A safe house can be one of many things -- the home of a friend who willingly supports and sympathizes with whatever covert activities you might undertake; the home of someone who can be bribed, tricked, blackmailed or forced into offering their home for refuge; or a home, apartment, hotel room, business or other location for rent.
There are usually two types of uses for safe houses: defensive and offensive. A defensive safe house is one that hides people and keeps them safe from investigation, capture or surveillance. For example, after Danish newspapers published pictures of Muhammad in 2006, several of the cartoonists went into hiding because of death threats from offended Muslims [source: New York Times]. An offensive safe house, on the other hand, would serve as a place for people to conduct covert operations. An apartment rented by CIA spies could serve as an offensive safe house if they were running surveillance on a member of the Mafia.
Of course, regardless of the reasons for using a safe house, keeping the location and any activities within or without the house secret is the most important part. Once a secret location is no longer secret, the person in hiding must pick up and find another safe house or risk detection. Constantly moving around makes any operation difficult, so there are several basic requirements that define an effective safe house:
- Easy access/escape routes - A safe house must be easy to enter and even easier to get out of. Once a person becomes aware that someone is on his trail, leaving the location as quickly as possible is the only way to avoid capture.
- Access to transportation - A getaway car is much faster than escaping on foot if the safe house is found. A subway, railway or bus system is also very helpful, especially because it allows a person to blend in with crowds.
- Ability to observe approach - Anyone should be able to detect easily any suspicious activity going on near the safe house. Most spies prefer safe houses out in the country -- they provide easy access, privacy, parking, few nosy neighbors and a good view of the house and the surrounding land. Of course, a safe house in the city may be the only option if an operation focuses on an urban area. Heavily curtained windows and thick walls are a plus, but the location should still appear ordinary. Concrete windows might give too much away.
- Simplicity - Those operating a safe house shouldn't worry much about decorating. The less there is in a living space, the easier it will be to spot any changes from intruders, and it becomes harder for someone to place microphones and other surveillance technologies in the house.
- Hiding places - Documents, weapons and even people sometimes need a place to hide in a safe house. Attics, basements, crawl spaces and floor boards are great, and they can easily be covered by furniture or rugs.
