San Luis Obispo (Spanish for 'St. Louis the Bishop'; /sæn ˌlɪs əˈbɪsp/ san LOO-iss ə-BISS-poh;[9] Spanish: [san ˈlwis oˈβispo]; Chumash: tiłhini) is a city and county seat of San Luis Obispo County, in the U.S. state of California. Located on the Central Coast of California, San Luis Obispo is roughly halfway between the San Francisco Bay Area in the north and Greater Los Angeles in the south. The population was 47,063 at the 2020 census.[10]

San Luis Obispo was founded by the Spanish in 1772, when Saint Junípero Serra established Mission San Luis Obispo de Tolosa. The town grew steadily through the Mexican period before a rapid expansion of San Luis Obispo following the American Conquest of California. San Luis Obispo is a popular tourist destination, known for its historic architecture, vineyards, and hospitality, as well as for being home to California Polytechnic State University, San Luis Obispo.


The earliest human inhabitants of the local area were the Chumash people. One of the earliest villages lies south of San Luis Obispo and reflects the landscape of the early Holocene when estuaries came farther inland. The Chumash people used marine resources of the inlets and bays along the Central Coast and inhabited a network of villages, including sites at Los Osos and Morro Creek.[11] The tribal site on present-day San Luis Obispo was named tiłhini (Obispeño for 'Place of the full moon').[12]

Spanish period

The Spanish founded San Luis Obispo on September 1, 1772, when Saint Junípero Serra established Mission San Luis Obispo de Tolosa.

During the Spanish Empire expansion throughout the world, specifically in 1769, Franciscan Junípero Serra received orders from Spain to bring the Catholic faith to the natives of Alta California; the idea was to unify the empire under the same religion and language. Mission San Diego was the first Spanish mission founded in Alta California that same year.

On September 7, 1769, an expedition led by Gaspar de Portolá entered the San Luis Obispo area from coastal areas around today's Pismo Beach. One of the expedition's three diarists, padre Juan Crespí, recorded the name given to this area by the soldiers as Cañada de Los Osos ("cañada" translates as "valley" or "canyon," and Osos translates to "bears"). The party traveled north along San Luis Obispo Creek, turned west through Los Osos Valley, and reached Morro Bay on September 9.[13]

In 1770, Portola established the Presidio of Monterey and Junípero Serra founded the second mission, San Carlos Borromeo, in Monterey. The mission was moved to Carmel the following year.

In 1772, as the people of Presidio of Monterey and San Carlos Borromeo faced starvation, owing to a lack of supplies, Commander Pedro Fages (a member of the Portolà expedition) led a hunting expedition to the Cañada de Los Osos to bring back food. Over twenty-five mule loads of dried bear meat and seed were sent north to relieve the missionaries, soldiers, and neophytes (baptized natives). It was after this that Junípero Serra decided that La Cañada de Los Osos would be an ideal place for the fifth mission.[citation needed]

The area had abundant supplies of food and water, the climate was also very mild, and the local Chumash were very friendly. With soldiers, muleteers, and pack animals carrying mission supplies, Junípero Serra set out from Carmel to reach the Valley of the Bears. On September 1, 1772, Junípero Serra celebrated the first Mass with a cross erected near San Luis Creek. The very next day, he departed for San Diego leaving Fr. José Cavaller, with the difficult task of building the mission. Fr. José Cavaller, five soldiers and two neophytes began building the Mission San Luis Obispo de Tolosa which would later become the town of San Luis Obispo. Both the mission and the town were named after San Luis, obispo de Tolosa (St. Louis, bishop of Talouse, France).

Mexican period

When the Mexican War of Independence from Spain broke out in 1810, all California missions had to become virtually self-sufficient, receiving few funds or supplies from Spanish sources. Beginning soon after Mexico won her independence from Spain in 1821, anti-Spanish feelings led to calls for expulsion of the Spanish Franciscans and secularization of the missions. Because the fledgling Mexican government had many more important problems to deal with than far-off California, actual secularization did not happen until the mid-1830s.

After 1834, the mission became an ordinary parish, and most of its huge land holdings were broken up into land grants called ranchos. The ranchos were given by Mexican land grant from 1837 to 1846, with the mission itself being granted in the final year. The central community, however, remained in the same location and formed the nucleus of today's city of San Luis Obispo.

American period

Following the American Conquest of California, San Luis Obispo was the first town incorporated in the newly formed San Luis Obispo County. It remains the center of the county to the present. Early in the American period, the region was well known for lawlessness.[14] It gained a reputation as "Barrio del Tigre" (or Tiger-Town) because of the endemic problem.[15] Robberies and murders that left no witnesses were carried out on along the El Camino Real and elsewhere around San Luis Obispo for several years. Finally a gang of eight men committed a robbery with three murders and a kidnapping at the Rancho San Juan Capistrano del Camote in May 1858, that uncharacteristically left two witnesses alive. This brought about the formation of a vigilance committee in the County that killed one, the suspected leader of the gang Pio Linares, and lynched six others, a total of seven men suspected of such misdeeds (the most lethal in California history).[14][15][16] Members of the committee remained influential members of the community for decades.

The ranchos remained focused on cattle after the conquest of California. With the discovery of gold, the county experienced a major economic surge with the rising price of beef, with the highest prices coming in 1851. The county remained focused on cattle until 1863, when a drought left most ranchos devastated. Residents quickly turned to other venues, leading to the breaking up of many of the ranchos and a major change in the economic climate of the town, which focused less on cattle ranching and more on dairies, agriculture, and mined goods from then onward.

San Luis Obispo once had a burgeoning Chinatown in the vicinity of Palm Street and Chorro Street. Laborers were brought from China by Ah Louis in order to construct the Pacific Coast Railway, roads connecting San Luis Obispo over the Cuesta Pass to Paso Robles and from Paso Robles to Cambria, and also the 1884 to 1894 tunneling through Cuesta Ridge for the Southern Pacific Railroad. The town's Chinatown revolved around Ah Louis Store and other Palm Street businesses owned and run by Chinese business people. Today, Mee Heng Low chop suey shop is all that remains of the culture, although a slightly Chinatown-themed commercial development has been planned. A display of some of the unearthed relics from this period can be seen on the first floor of the Palm Street parking garage, which was built over the location where Chinatown once stood. The San Luis Obispo Historical Society (adjacent to the Mission) also contains rotating historical exhibits.[17]

San Luis Obispo was also a popular stop en route to Los Angeles. U.S. Route 101 and California State Route 1 were constructed with the rise of car culture. Due to its popularity as a stop, it was the location of the first motel in the world, the Milestone Mo-Tel.

San Luis Obispo is located on U.S. Route 101, about 31 miles (50 km) north of Santa Maria.

According to the United States Census Bureau, the city has a total area of 13.25 square miles (34.3 km2), of which, 13.1 square miles (34 km2) is land and 0.15 square miles (0.39 km2) (1.13%) is water.

San Luis Obispo is on the West Coast of the United States and in the Central Coast of California. The Pacific Ocean is about 11 miles (18 km) west of San Luis Obispo. The Santa Lucia Mountains lie just east of San Luis Obispo. These mountains are the headwaters for San Luis Obispo Creek, whose watershed encompasses 84 square miles (220 km2) surrounding the city and flows to the Pacific Ocean at Avila Beach.[18]

San Luis Obispo is a seismically active area; there are a number of nearby faults including the San Andreas Fault. The Nine Sisters are a string of hills that partially run through San Luis Obispo. They are geologically noteworthy for being volcanic plugs. Six of the nine peaks are open to the public for recreation.[19]

San Luis Obispo experiences a warm Mediterranean climate (Köppen climate classification Csb). On average it has 50 days with measurable rain per year, mostly during winter months. Summers are generally warm and sunny, often with morning fog from the Pacific coast. Winters are generally mild, though below freezing lows occur 2.6 nights per year on average.[20] Measurable snowfall in San Luis Obispo has not officially been recorded since records began in 1870, although photos show about 0.3 inches (0.76 cm) fell in 1922 and snow flurries were reported in both 1988 and 2006. Temperatures do, however, vary widely at any time of the year, with 80 °F (27 °C) readings in January and February not uncommon.

Although heat extremes above 110 °F (43.3 °C) have been recorded, the maritime moderation is generally strong due to the proximity to the cool ocean waters. The hottest temperature on record is officially at 113 °F (45 °C) on September 6, 2020, although a 120 reading was reported in the local news.[21] Nights remain cool year round due to cold-current ocean air in summer and being in a valley subject to inversion, although seldom cold. The warmest night recorded was 75 °F (24 °C) on September 22, 1939, and the coldest day at 40 °F (4 °C) on December 11, 1932.[22]

Downtown San Luis Obispo has many eclectic shops and boutiques.[26] Takken's Shoes is headquartered in San Luis Obispo. Ernie Ball's Music Man factory is located in San Luis Obispo. Mindbody and iFixit have been headquartered in San Luis Obispo since their inceptions. In 2019, SLO experienced a boom in home construction along with continued building of commercial structures. As housing had not kept up with job growth, many people who cannot afford to live where they work, commute to their jobs in SLO.[27]

Pacific Gas and Electric is the largest non-governmental employer in the city.[28] In 2016, they announced the closure of the Diablo Canyon Nuclear Power Plant in 2025, which will cost the local economy 1,500 jobs with an average salary of $157,000, as well as nearly $1 billion annually in economic activity. Congressman Salud Carbajal introduced H.R. 5441 to the House of Representatives in order to create Energy Opportunity Zones, which is designed to specifically target areas that have had a nuclear power plant shut down within 10 years (including San Luis Obispo) for federal tax credits for renewable energy generation, including solar, wind, and wave energy.[29]

San Luis Obispo is incorporated as a charter city. It is also the county seat of San Luis Obispo County. The city charter provides for a "Council-Mayor-City Manager" form of municipal government.[31] The city council has five members: a mayor who is elected to two-year terms, with each mayor limited to serving no more than four consecutive terms, and four city council members who are elected to four-year terms, with each council member limited to serving no more than two consecutive terms.[32]

The fire department of San Luis Obispo was first organized in 1872 and now has 45 full-time firefighters and four fire stations (as of 2007).[33] The SLO City Fire Stations are staffed with three-man ALS engine companies and a four-man ALS Truck company. Each apparatus has at least one paramedic on duty each day. The department responds to over 4,500 calls each year. The San Luis Obispo City Fire Department also maintains a bike medic program which is used at the Farmers' Market and other special events throughout the city. Four members of the Fire Department are also on the San Luis Obispo SWAT Team as SWAT Medics and respond using Squad 1 (an ALS equipped ambulance which also carries some light rescue gear and other specialty tools) The front-line members of the department are represented by the San Luis Obispo City Firefighters' IAFF Local 3523.[33]

The City of San Luis Obispo Utilities Department can trace its lineage back to 1872 when plans were made to provide the city with safe drinking water.[34] Currently the Utilities Department operates a water treatment plant designed to treat 16 million gallons a day, the Whale Rock Reservoir located in Cayucos, CA, a water distribution system including 15 pressure zones and 150 miles of water mains.[35] The Water Resource Recovery Facility treats 4.5 million gallons per day and is currently undergoing a plant upgrade expected to be completed in 2021.[36]

Notable ordinances

The County Government Center
San Luis Obispo Chamber of Commerce, located in downtown

In June 1990 City Councilman Jerry Reiss proposed a city ordinance to ban smoking in all indoor public areas. Following a failed effort [citation needed] by R. J. Reynolds Tobacco Company to defeat the ordinance, the City Council voted 4–1 in favor on June 19, 1990, with only Mayor Ron Dunin dissenting. As a result, on August 2, 1990, San Luis Obispo became the first municipality in the world to ban smoking in all public buildings, including bars and restaurants. This statute has been a catalyst worldwide in anti-smoking legislation.[37][38][39] In April 2010, San Luis Obispo strengthened its anti-smoking legislation, making smoking in public, excepting for certain conditions, a citable offense beginning on June 20, 2010.[40]

In 1982, following public hearings, the city council approved an ordinance forbidding the construction of "drive-through" businesses.[41] In-N-Out Burger opened a restaurant in the nearby town of Atascadero because of the ban.[42] In 2008 the City Council voted 3–2 to keep the ban.[43][44]

In April 2010, an "unruly gathering" ordinance passed with a vote of 4–1. This ordinance poses a fine of $700 for the hosts of gatherings with more than 20 people on private property that create a substantial disturbance in a significant amount of the neighborhood. Unlawful conduct includes excessive noise; public drunkenness; serving alcohol to minors; fighting; urinating in public; crowds overflowing into yards, sidewalks, or streets; or similar unlawful behaviors.[45][46]

State and federal representation

In the California State Legislature, San Luis Obispo is in the 17th Senate District, represented by Democrat John Laird, and in the 30th Assembly District, represented by Democrat Dawn Addis.[47]

In the United States House of Representatives, San Luis Obispo is in California's 24th congressional district, represented by Democrat Salud Carbajal.[48]


California Polytechnic State University, San Luis Obispo
Mission College Prep. School

All public K–12 institutions in San Luis Obispo are operated by San Luis Coastal Unified School District, which contains six elementary schools, one middle school (Laguna Middle School), and one high school, San Luis Obispo High School. The district also operates several schools outside of San Luis Obispo in nearby Avila Beach, Edna Valley, Morro Bay, and Los Osos.[49] Additionally, Mission College Preparatory Catholic High School and Old Mission School (est. 1876 as The Academy of the Immaculate Heart of Mary) operate privately within the Diocese of Monterey.

San Luis Obispo is home to California Polytechnic State University (Cal Poly), a public university enrolling 21,812 students as of fall 2018.[50] The school is just outside city limits and provides on-campus housing for nearly 6,000 freshmen and sophomores.

The area is also served by Cuesta College, part of the California Community College System.


The Madonna Inn is one of San Luis Obispo's more famous landmarks.

The Madonna Inn is an eccentric landmark established by Alex Madonna in 1958. The Fremont Theater, a historic Art Deco theater from the 1940s, once played first-run movies on the huge screen, and now hosts stage performances. Murals adorn the walls of the main theater while neon swirls light the ceiling. The Palm Theatre boasts solar heating and is home to the San Luis Obispo International Film Festival. Since about 1960, people have been sticking chewed gum on the walls of Bubblegum Alley. The doctor's office on the corner of Santa Rosa and Pacific streets is one of very few commercial buildings designed by Frank Lloyd Wright. San Luis also has a Carnegie Library which is now home to the San Luis Obispo County Historical Museum.[51]

The "underground city" is a series of tunnels beneath the city.[52]

One of the largest Mardi Gras parades west of the Mississippi was held in San Luis Obispo, but canceled in 2005 because of difficulties related to crowd control and alcohol consumption.

The infamous Bubblegum Alley in downtown San Luis Obispo

Cal Poly's open house, Poly Royal, was held annually from 1933 to 1990, though canceled in 1945 due to war rationing.[53] It began as a show-and-tell for students to display their projects. It traces its origins to the 1904 Farmer's Institute and Picnic Basket. By the 1980s, as the college became "the most in the 19-campus CSU system", Poly Royal began drawing over 100,000 people from throughout the state, including 126,000 people in 1985. Concerts, parties, and other entertainment were added and it earned $3–4 million in revenue for the city every year.[54][55]

San Luis Obispo has been home of several other events, including a stop on the way of the Olympic Flame Relay, the Tour of California bicycle race, Cinco de Mayo celebrations, and a long-standing Christmas Parade. In May, the Madonna Hotel hosts the annual California Festival of Beers, which includes beer tasting of over 200 craft beers. Another attraction is the development of Edna Valley into a well-known wine region. Just south of the city, people can spend an afternoon wine tasting several wineries in the area with a very short drive. The wine region extends north beyond Paso Robles (30 miles north) and south to Santa Ynez (70 miles south).[citation needed]

The Dallidet Adobe, built in 1856, is one of the oldest residences in town.

During summer months, a free outdoor concert Friday evening is called Concerts in the Plaza. Other noteworthy events include the San Luis Obispo International Film Festival, Festival Mozaic, a classical and crossover music festival, and the Plein Air Festival.[56]

Every Thursday night San Luis Obispo hosts a farmers' market. Five blocks of Higuera St are blocked off to allow vendors to sell food and goods and various visual and music artists perform.[57]

Since June 2000, the first Thursday of every month is The Bike Happening (also known as Bike Nite) in San Luis Obispo. People gather at the Mission Plaza with their bikes. The bikers go around on multiple circuits on the main streets of downtown.

Restaurant in downtown San Luis

One of the cultural focal centers of San Luis Obispo is the Christopher Cohan Performing Arts Center built on the Cal Poly campus, which was constructed utilizing the donations of local businesses and individuals. The Performing Arts Center consists of multiple venues, including the original Spanos Theatre. The largest venue, Harmon Hall, seats 1,300. Many high school and college programs are scheduled. Local artists perform plays, music and dance. The addition of the Performing Arts Center attracts many touring performances which are usually not found in communities of comparable size to San Luis Obispo. The summer of 2007 was the opening concert of the Forbes Pipe Organ, which was built elevated into a side wall of Harmon Hall and required the donation of a further $3 million for purchase and installation.[58]

The San Luis Obispo Museum of Art began in the 1950s when a small group of artists, educators and enthusiasts established the foundation. Over the years, the San Luis Obispo Art Association evolved into the San Luis Obispo Art Center, which evolved into the San Luis Obispo Museum of Art. The museum, with a focus on California Contemporary Art, shows 24 exhibitions per year, has both adult and children's art classes, and hosts art talks, films and other events. The museum launched a $15 million Capital Campaign for a new building in 2017.[59][60]

U.S. Route 101 and California State Route 1 are the major north–south highways in San Luis Obispo, linking the city to the rest of the Central Coast region, San Francisco to the north, and Los Angeles to the south. Both enter the city from the south as a concurrency. As they head north, Highway 1 then splits towards the coast to Morro Bay, while Highway 101 stays more inland to Atascadero and Paso Robles. California State Route 227 provides an alternate route to Highway 101 from San Luis Obispo south to Arroyo Grande.


Bicycling is increasing as a mode of transportation. The Bill Roalman (Morro Street) Bicycle Boulevard gives priority to bicycle traffic while a special bicycle traffic signal (one of only a handful in the United States) allows bicyclists their own phase in traffic flow.[70] The SLO County Bicycle Coalition offers a free bicycle valet service during the weekly Farmers' Market. In 2007, the city was designated as a Bicycle Friendly Community at the Gold level by the League of American Bicyclists.
