The completion of Interstate 5 in 1959 enabled easy access to job centers in Los Angeles County, creating a boom in the Orange County housing market.
In 1959, Cabot, Cabot & Forbes and Paine Webber partnered to form the Laguna Niguel Corporation, which purchased the Daguerre land to develop one of California's first master planned communities.
The initial 7,100-acre (2,900 ha) town plan was created by Viennese architect Victor Gruen and expanded beginning in 1971 by AVCO Community Developers after they acquired the Laguna Niguel Corporation.
The name of the city was created from "Laguna", a reference to the tidal lagoon that once formed at the mouth of Aliso Creek, and the name of the Acjachemem village Niguili that once occupied the area.
As the city would be developed in stages, ranchers and farmers signed annual leases with the Laguna Niguel Corporation to use the land until the planned communities were built.

In contrast to a traditional bedroom community, Laguna Niguel was designed so that "families should have most of their economic needs and their social and cultural interests met by facilities within the community".
The plan was also notable for its emphasis on parks and open space – comprising nearly a third of the land to be developed.
The Laguna Niguel Corporation went public in April 1959 and raised an initial $8.2 million from investors.
In 1962 the first tracts of Monarch Bay and Niguel Terrace were completed, consisting of 565 homes.
In 1960, the Moulton Niguel Water District (which today serves all of Laguna Niguel) was established by a conglomerate of ranchers, to import water from the Colorado River Aqueduct as the area lacked a sufficient natural water supply.
In 1964, Crown Valley Parkway was completed from I-5 to the Pacific Coast Highway, facilitating transport through the growing city.
By 1965 the population of Laguna Niguel reached 1,000.

The Laguna Niguel Homeowner's Association was formed in 1966 as an advisory to the Orange County Board of Supervisors (which governed the as-yet unincorporated city).
In 1973 Laguna Niguel Regional Park opened to the public.
The Chet Holifield Federal Building (a local landmark popularly known as the "Ziggurat"), designed by William L. Pereira, was constructed for Rockwell International and was meant to bring 7,000 jobs to the area.
After the end of the Vietnam War, Rockwell reportedly lost a defense contract with the federal government and the building was left unoccupied.
It was eventually traded to the US General Services Administration in exchange for industrial facilities elsewhere.

The Ziggurat, which was completed in 1971 well before the development of residential communities in the area, is one of Laguna Niguel's most noticeable landmarks.
The Orange County Register described it as "the only constant in an ever developing locale."
It houses millions of microfilms as documents of land agreements between the American government and Native American tribes of the southwest United States.
It is also home to the Western Regional Department of Homeland Security and the California Service Center of the United States Citizenship and Immigration Services.
The building was featured in an ending scene for the 1975 sci-fi movie Death Race 2000 and as the headquarters for the Luckup Corporation in the 1983 movie Deal of the Century.
It was also used for the 1995 movie Outbreak, where it served as the exterior for the Centers for Disease Control headquarters.
