Leisure World is a census-designated place and unincorporated area in Montgomery County, Maryland, United States.

[4] Cortese planned to build clubhouses, a swimming pool, riding stables, an auditorium, a shopping center, medical facilities, a hotel for guests, an 18-hole golf course, and an 8-acre lake at the site.

[8][5] The one dissenting council member was Kathryn E. Diggs, who said she was skeptical that the development would be economically successful.

[9] Within a few months, Washington Suburban Sanitary Commission approved 28,000 feet of water and sewer lines for the development.

[16] J. Robert Conybeare served as general sales manager,[17] and Angus T. Johnson was named the first administrator of the community.

[19] The community facilities were held in trust by the Foundation of Leisure World, a 501(c)(3) nonprofit organization,[20][21] with former Under Secretary of the Navy Kenneth E. BeLieu as its first president.

[22] Homes were sold as co-ops, with prices starting at $15,000 and ongoing monthly maintenance payments of at least $85.

[26] Commercial leases were signed with Safeway, Peoples Drug Stores, Hot Shoppes cafeteria-style restaurant, and Maryland National Bank for space at the adjoining shopping center.

[25] The Interfaith Meeting House broke ground on October 22, 1965, with plans for a capacity for 500 people.

[31] Sales of units at Leisure World were suspended in September 1967 after a tight mortgage market significantly increased prices and lower than expected interest.

[26] In October 1974, Leisure World canceled the sales contracts for 480 semidetached homes and low-rise apartments because inflation had increased construction costs and it was no longer certain when the units would actually be built.

[35] Almost one year later, the developer sued the state of Maryland, saying Washington Suburban Sanitary Commission failed to complete a 1965 contract to provide water and sewer connections to the area because the Maryland Department of Health and Mental Hygiene had ordered a halt to sewer connections in 1973.

[36] The developer also said it was strong-armed into building a sewage treatment facility by the Montgomery County government in order to avoid significant financial losses.

[39] In February 1970, Zero Manufacturing Company agreed to buy Rossmoor Corporation, the developer of Leisure World.

[40] On March 1, 1968, there was a fire in a model two-story townhouse on Gleneagles Drive at Leisure World.

[41] There was one injury; Chief Sidney Bailey of Sandy Spring Fire Department was treated for burns to the eye.

[47][48] Montgomery County Planning Board had agreed to change the land's zoning from low density to higher density on the condition that all residents would be of age 50 or older and, in a vote of 4–1, Montgomery County Planning Board would not let Leisure World out of its agreement.

[26] The plaintiffs contended that the population of the 2,500 homes without age restrictions would be much larger than originally intended because many of the units would be occupied by families.

[26] The plaintiffs said that the additional residents would cause an increase in public service costs and a decrease in their property values.

[51] According to the United States Census Bureau, the place has a total area of 1.1 square miles (2.8 km2), all land.
