Homeless shelters are a type of homeless service agency which provide temporary residence for homeless individuals and families. Shelters exist to provide residents with safety and protection from exposure to the weather while simultaneously reducing the environmental impact on the community. They are similar to, but distinguishable from, various types of emergency shelters, which are typically operated for specific circumstances and populations—fleeing natural disasters or abusive social circumstances. Extreme weather conditions create problems similar to disaster management scenarios, and are handled with warming centers, which typically operate for short durations during adverse weather.

Hundreds of homeless individuals die each year from diseases, untreated medical conditions, lack of nutrition, starvation, and freezing to death. In a mild-wintered San Francisco in 1998, homeless people were purportedly 58% more likely to perish than the general population. In New Orleans, approximately 10,000 homeless were unaccounted for after Hurricane Katrina in 2005. Residents of homeless shelters may also be exposed to bed bugs which have been growing more prevalent in countries such as the United States, Canada and in Europe. Some residents of shelters have reported sleeping in roach-infested spaces at various shelters. In Washington, D.C., statistics indicate that 63% of homeless people suffer from a lack of access to regular bathing. Another estimated 58% within the same city are unable to obtain sufficient levels of sleep. Areas such as showers and bathrooms in shelters often have restricted access with limited hours. Homeless individuals also have great trouble finding storage locations for their belongings. Homeless individuals in the United States are subject to being arrested and held in jail for “quality of life” violations or for public intoxication. In Hawaii, homeless people are banned from sitting or lying on the streets. The LGBT homeless are at increased risk of violence compared to other groups. Transgender people are also at danger of being placed into the incorrect shelters. In some cases, transgender women can be turned away from women's shelters. This can place their safety at risk. In a national survey conducted in the United States the findings showed that of the surveyed homeless, two-thirds are men and most likely to be single adults between the ages of 25 and 54. One out of every four men experiences domestic violence. In addition, young men who have been abused as children are more likely to become homeless and are at risk of becoming chronically homeless if they are not living in a permanent situation by age 24. Women are at great risk of both homelessness and poverty because they are most likely to bear child-rearing responsibilities and vulnerable to become victims of family members or “intimate partners.” In a survey conducted in the 2013 showed that in an emergency shelter in Texas, women were the majority population, though this is not a trend reflected in the majority of the country. Homeless women, both those with children and without, experience higher rates of physical illness than men. They are also more likely to be hyper-vigilant and have high levels of stress. Women seeking refuge from domestic violence are not always able to find rooms in shelters. Some women have been turned away from homeless shelters because shelter staff believe that turning women away will stop people from having sex inside the shelter. Homeless women who are of childbearing age also face unique hygiene issues because of menstruation. Homeless shelters have noted that both tampons and sanitary pads “top the list of needs at shelters” because of their high cost and because they are not donated often.
