Earthquake Shacks (1906)
The Earthquake Shacks of 1906 were temporary housing structures erected throughout San Francisco in the immediate aftermath of the devastating earthquake and fire of April 18, 1906. These hastily constructed wooden dwellings, often referred to colloquially as "earthquake shacks," served as emergency shelter for an estimated 200,000 to 300,000 displaced residents whose homes had been destroyed during the disaster.[1] Built rapidly between mid-1906 and 1908, these modest structures became a defining feature of the city's landscape during its reconstruction period and represented an innovative, if temporary, solution to one of the most urgent humanitarian crises in American urban history. They weren't much to look at. Single rooms or small multi-room units built from scrap lumber, corrugated metal, and salvaged materials made up most of the camps. Though intended as short-term solutions, many remained standing for years, creating distinct neighborhoods and fundamentally shaping how San Francisco approached urban planning and disaster relief.
History
The April 18, 1906 earthquake struck San Francisco at 5:12 a.m., triggering fires that burned for three consecutive days and destroyed approximately 80 percent of the city's building stock. Nearly 300,000 people suddenly needed shelter. The city's existing housing stock couldn't absorb such displacement. Mayor Eugene E. Schmitz and business leaders established the San Francisco Relief and Red Cross Fund to coordinate initial relief efforts, but conventional housing construction couldn't proceed at the necessary speed. It was clear that temporary structures would be necessary to prevent mass homelessness and maintain public order during the reconstruction process.[2]
Starting in May 1906, city government authorized construction of earthquake shacks on public lands, particularly in Golden Gate Park, Washington Park (now known as Alta Plaza), and the Presidio. A combination of hired workers and displaced residents themselves constructed the shacks, using materials salvaged from the ruins and newly milled lumber supplied by the city. By June 1906, approximately 5,600 shacks had been erected in Golden Gate Park alone, with thousands more built throughout the city. These structures were typically about 10 feet by 12 feet in size, with wooden frames covered in rough lumber siding or canvas. Some included small wood stoves for heating and cooking. The architectural style was purely utilitarian, reflecting the emergency circumstances and the pressing need for rapid construction rather than any aesthetic consideration.
The shack villages developed their own informal governance structures and community organizations. Residents established neighborhood associations, markets, and social services within the camps, and by 1907, some of these temporary settlements had acquired distinctive characters and identities. Golden Gate Park held the largest concentration, where thousands of families occupied the grounds for extended periods. As permanent reconstruction progressed, the shacks were gradually demolished, though the process moved slower than anticipated. Many residents who'd lost everything possessed limited financial resources to rebuild and remained dependent on emergency housing. By 1908, most of the major camps had been cleared, though scattered shacks persisted in various locations throughout the city for several years afterward. The last officially documented earthquake shack wasn't removed until 1911.
Geography
The earthquake shacks were distributed across multiple geographic locations within San Francisco, though they were concentrated in areas with available public land and proximity to displaced population centers. Golden Gate Park became the primary location for temporary housing, with entire neighborhoods of shacks occupying the park's central and eastern sections. The park's large, accessible space made it ideal for rapid expansion of shelter facilities, and its location provided reasonable access to downtown areas where reconstruction work was occurring and employment opportunities existed. More than 40,000 people lived in Golden Gate Park shack settlements at peak occupancy, representing the largest concentration of temporary housing anywhere in the city.[3]
The Presidio, San Francisco's major military installation, also accommodated significant numbers of earthquake shacks, particularly in areas that wouldn't interfere with military operations. Recognizing the crisis, the federal government allowed the Army to coordinate provision of some temporary structures and supplies. Washington Park, located on the slopes of what would later become known as the Pacific Heights neighborhood, hosted another substantial shack settlement. Van Ness Avenue, the city's widest street, became a natural firebreak during the 1906 fires and subsequently became a focus of reconstruction activities; temporary housing also appeared in surrounding areas. The geographic distribution of shacks reflected both practical considerations regarding available land and social dynamics, as some neighborhoods developed more cohesive community structures than others. Because the shacks occupied public lands, residents had no property rights and could be displaced when the city determined that the land should be returned to its original purposes or developed for permanent reconstruction.
Culture
Life in the earthquake shack communities developed distinctive cultural characteristics despite the hardship and impermanence of the settlements. Residents from diverse backgrounds, including Italian, Irish, and Chinese immigrant communities, lived in unprecedented proximity, creating complex social dynamics. Churches, temples, and religious organizations established themselves within the camps, offering not only spiritual services but also crucial social support networks. Newspapers and community bulletins were published specifically for shack residents, keeping them informed about relief assistance, reconstruction progress, and city regulations. Schools were established to serve children, though often in inadequate quarters, and educators worked to maintain educational continuity despite the disruption.
These communities occupied a unique cultural space. The disaster was traumatic, yes, but the shack communities represented both resilience and communal solidarity in response to catastrophe. Residents developed humor and coping mechanisms to deal with their circumstances, and voluntary organizations flourished within the camps. The shared experience of displacement and collective recovery efforts created bonds between individuals who might never have otherwise interacted in the city's increasingly stratified pre-earthquake society. Yet the shacks also became associated with poverty, displacement, and urban dysfunction in the minds of wealthier San Franciscans who advocated for rapid demolition and reconstruction. This cultural tension between viewing the shacks as heroic expressions of community resilience and seeing them as evidence of urban disorder shaped contemporary discourse about the city's recovery and future development.
Economy
The economic implications of the earthquake shacks were substantial, affecting labor markets, supply chains, and municipal finances. Shack construction itself required significant resources and represented one of the earliest large-scale public works projects undertaken by the city. Lumber suppliers, construction workers, and material handlers found employment in shack construction, providing income to displaced workers during the crisis. The shack settlements also created demand for goods and services, with small merchants, food vendors, and service providers establishing businesses within and adjacent to the camps. This informal economy helped sustain residents with limited savings and provided some economic activity during the period when formal employment opportunities remained disrupted.
Land was money. Property owners anxious to recover lost investments pushed for rapid clearance of shack settlements to enable reconstruction. Valuable real estate, particularly in central locations, was occupied by temporary housing that blocked the city's economic recovery. City officials faced intense pressure to accelerate demolition schedules and force residents to relocate. Some historians argue that the eagerness to clear the shacks contributed to patterns of displacement that disproportionately affected working-class and immigrant communities, ultimately reshaping San Francisco's demographic and economic geography in ways that persisted for decades. The municipal government incurred substantial expenses in shack construction and maintenance, funds that competed with other reconstruction priorities and contributed to the city's financial strain during the recovery period.
