The hilly City by the Bay is as famous for its urban grit and grime as it is for its iconic landmarks. If you’re short on time, here’s a quick answer to your question: San Francisco is considered a particularly dirty city because of its large homeless population, limited public garbage cans, and policies that enable public drug use and camping.

In this comprehensive article, we’ll explore the complex factors that contribute to San Francisco’s ongoing cleanliness challenges. We’ll look at the city’s homelessness crisis, waste management practices, tolerance of public drug use, and more to understand why San Francisco has earned a reputation for being dirty compared to other major U.S. cities.

San Francisco’s Large Homeless Population

One of the main reasons why San Francisco is considered to be dirty is due to its large homeless population. It is estimated that there are over 8,000 homeless residents in the city, making it one of the highest rates of homelessness in the country.

Estimate of over 8,000 homeless residents

According to the San Francisco Homeless Point-in-Time Count, which is conducted every two years, there were 8,035 homeless individuals in the city as of January 2020. This number includes both sheltered and unsheltered individuals.

The high number of homeless residents poses various challenges for the city, including sanitation issues and increased littering. Lack of access to proper facilities leads to increased waste on the streets and in public spaces, contributing to the overall cleanliness concerns.

Tent encampments and street sleeping are common

Another visible aspect of San Francisco’s large homeless population is the prevalence of tent encampments and street sleeping. These makeshift shelters can be found throughout the city, particularly in areas such as the Tenderloin and South of Market neighborhoods.

The presence of tent encampments not only contributes to the overall untidiness but also raises concerns about public health and safety. It can lead to issues such as littering, drug use, and crime, which further add to the perception of San Francisco being dirty.

Sidewalks often blocked by people and belongings

One of the most noticeable effects of the large homeless population in San Francisco is the blocking of sidewalks by people and their belongings. It is not uncommon to encounter sidewalks filled with tents, mattresses, shopping carts, and personal belongings, making it difficult for pedestrians to navigate through the city.

This creates an unpleasant environment for both residents and tourists alike and contributes to the perception of San Francisco’s uncleanliness. Efforts have been made by the city to address this issue, including regular clean-up initiatives and providing alternative housing options for the homeless population.

However, finding effective and long-term solutions to address the challenges posed by the large homeless population remains a complex issue for San Francisco.

Limited Public Garbage Cans

One of the major reasons why San Francisco is known for being dirty is the limited number of public garbage cans scattered around the city. With only about 3,000 public trash bins available, it is clear that the city is facing a significant shortage.

Insufficient for a city with high foot traffic and street food

Considering the high foot traffic and the popularity of street food in San Francisco, it is evident that the current number of public garbage cans is insufficient. The city attracts millions of tourists each year, and locals often enjoy eating on the go, leading to an increased accumulation of waste.

This lack of sufficient disposal options poses a challenge in maintaining cleanliness.

Leads to litter ending up on sidewalks and streets

The scarcity of public garbage cans in San Francisco exacerbates the problem of litter ending up on sidewalks and streets. Without proper disposal options readily available, people often resort to littering or leaving their trash behind.

This not only creates an unsightly environment but also contributes to the overall uncleanliness of the city.

According to a report from the City and County of San Francisco, the limited number of public garbage cans has been a long-standing issue. Efforts have been made to increase the number of bins, with additional funding allocated for this purpose, but progress has been slow.

San Francisco could take inspiration from other cities that have successfully implemented comprehensive waste management systems. For example, Tokyo, Japan, is known for its highly efficient and well-maintained garbage disposal infrastructure.

By implementing similar strategies, San Francisco can significantly improve its cleanliness and reduce the amount of litter on its streets.

Policies Tolerating Public Drug Use

One of the major factors contributing to the cleanliness issues in San Francisco is the policies that tolerate public drug use. This leniency has resulted in a proliferation of open drug dealing and use, especially in the Tenderloin district.

The city’s tolerance towards drug use has created an environment where drug users feel comfortable openly engaging in their activities, leading to increased drug-related litter and unsanitary conditions.

Open drug dealing and use, especially in Tenderloin district

The Tenderloin district in San Francisco has become notorious for its open drug dealing and use. The district has a high concentration of homeless individuals and drug addicts, who openly consume and sell drugs on the streets.

This not only creates an unsafe environment for residents and visitors but also contributes to the overall cleanliness issues in the city.

Hypodermic needles and other paraphernalia left on streets

Another consequence of the policies tolerating public drug use is the presence of hypodermic needles and other drug paraphernalia left on the streets. Drug users often discard their used needles and other items in public spaces, posing a significant health risk to both the community and sanitation workers.

The improper disposal of these items further exacerbates the cleanliness problems in San Francisco.

Feces and urine around encampments and sidewalks

The policies that tolerate public drug use have also contributed to the issue of feces and urine around homeless encampments and sidewalks. Many individuals experiencing homelessness lack access to proper restroom facilities, leading them to relieve themselves in public spaces.

This not only creates unsanitary conditions but also contributes to the overall uncleanliness of the city.

Addressing the cleanliness issues in San Francisco requires a comprehensive approach that includes not only improving sanitation services but also reassessing the policies that tolerate public drug use.

By implementing stricter regulations and providing support for individuals struggling with addiction, the city can work towards a cleaner and healthier environment for all residents and visitors.

Insufficient Street Cleaning and Maintenance

One of the main reasons why San Francisco is known for its dirty streets is the insufficient street cleaning and maintenance. Despite the city’s efforts to keep the streets clean, the cleaning crews are often stretched thin across the city.

Cleaning crews stretched thin across the city

San Francisco is a bustling city with a large population, and the demand for street cleaning services is high. Unfortunately, the number of cleaning crews available is not enough to keep up with the demand. This results in some areas of the city being neglected and not receiving regular cleaning.

The lack of sufficient cleaning crews can be attributed to budget constraints and resource allocation. With limited resources, the city has to prioritize certain areas over others, leading to disparities in cleanliness across different neighborhoods.

Pressure washing and steam cleaning not frequent enough

Another factor contributing to the dirtiness of San Francisco’s streets is the infrequency of pressure washing and steam cleaning. While these methods are effective at removing dirt, grime, and stains, they are not performed as frequently as needed.

Pressure washing and steam cleaning are particularly important for areas that experience heavy foot traffic, such as downtown and tourist hotspots. However, due to the limited availability of equipment and personnel, these areas may not receive the necessary cleaning as often as they should.

Graffiti and illegal dumping often not addressed quickly

Graffiti and illegal dumping are common issues in any city, and San Francisco is no exception. However, one of the reasons why these problems persist is the lack of prompt action in addressing them.

When graffiti appears on buildings or public spaces, it should be removed as soon as possible to discourage further vandalism. Similarly, illegal dumping should be addressed promptly to prevent the accumulation of trash and debris.

Unfortunately, due to various reasons such as limited resources and bureaucratic processes, graffiti and illegal dumping are not always addressed quickly in San Francisco. This can give the impression that the city is dirty and not well-maintained.


In summary, San Francisco’s visibly dirty streets can be attributed to an insufficient number of public trash cans, policies enabling street homelessness and drug use, and inadequate cleaning resources and operations. With human waste, needles, litter, and graffiti prevalent across many neighborhoods, San Francisco has earned a notorious reputation for urban grit and grime compared to other major American cities.
