• History

  La Habra was founded in 1896 around a post office in a corner store, incorporated on January 20, 1925 with 3,000 people and had only nearly 5,000 by 1950. Before the tracts it was farm and oil country: water lines from the San Gabriel River area fed walnuts, citrus and avocados, Standard Oil opened the Coyote Hills District in 1912, and by 1928 La Habra was the largest avocado center in Southern California. The avocado is still the official city tree.

• Water supply

  In fiscal 2024-25, about 73 percent of supply was Main San Gabriel Basin groundwater bought from California Domestic Water Company, 22 percent came from the city's Idaho Street and Portola wells in the La Habra Basin, and 5 percent was imported. The tie is old: the La Habra Water Company, incorporated in October 1902, originally owned half of California Domestic's stock.

• Heat

  The 2019 Hazard Mitigation Plan describes a semi-arid climate, averaging the high 80s in summer and the high 40s in winter, and ranks extreme heat second among its hazards, occurring more than once a year. It notes several area-wide power outages, typically blackouts caused by extreme heat.

• What needs a permit

  The city's permit process page lists additions, demolitions, new interior walls, new plumbing lines and fixtures, new wiring or light fixtures, and replacing or installing HVAC equipment as work that needs a building permit. Carpet, non-structural flooring, paint and wallpaper do not.

• Fire service

  Fire and paramedic service comes from the Los Angeles County Fire Department, which the city hires under contract, rather than the Orange County Fire Authority or a city department. It serves La Habra from Stations 191, 192, 193 and 194.

• Fire department plan review

  Some permits also need plan review and inspection by the Los Angeles County Fire Department, most often a solar system covering 50 percent or more of the roof. Improvements to buildings with fire sprinklers are on the same list.

• Wildfire zones

  The State Fire Marshal's March 24, 2025 map, as the city publishes it, shows Very High, High and Moderate zones along the southern edge next to Fullerton and a small pocket at the northeast corner by the county line, with the rest of the city unzoned. The city warns that some homes are newly included and says it will adopt an ordinance designating its Very High zones.

• Wildfire history

  The 2019 Hazard Mitigation Plan, written before the new maps, says wildfire risk is highest where La Habra borders La Habra Heights to the northeast and that the expected type is an urban fire. The one local fire it describes, two acres on July 4, 2017, suspected to have been started by illegal fireworks, burned in La Habra Heights rather than in the city.

• Earthquake risk

  The 2019 plan ranks earthquake as its only High hazard. It calls the 2014 event the La Habra Earthquake, reports no major damage in the city, and names the Whittier Fault along the Chino Hills, with probable magnitudes of 6.0 to 7.2, as long overdue.

• Flood zones

  The same plan ranks flood lowest: the city is not prone to urban flooding, FEMA's October 2017 maps place it in Zone X, and no properties were identified with repetitive flood losses.

• Old oil field

  The 1992 La Habra Hills Specific Plan says its roughly 380 acres are part of the 915-acre West Coyote Hills Field, then in oil production. Before a pool, addition or deep footing there, check the lot on the state's oil and gas well map.
