Deal Borough Hall is located at Durant Square (Norwood Avenue at Roseld Avenue), Deal NJ 07723; phone: 732-531-1454. The Borough was incorporated in 1898.
Deal is representative of the northern New Jersey shore development resulting from the coming of the railroad. During the 1860s, the completion of the Raritan and Delaware railroad lines to New York, and the Long Branch and Seashore lines along the beaches, signaled the opening of the shore to extensive growth. Deal rapidly gained a reputation for excess, and by the 1930s, its architecture was considered avant-garde as wealthy New York residents hired architects eager to experiment in a variety of revival, craftsman, and Japanese-influenced styles.
Only a small settlement in 1889, by the 1930s Deal Beach had grown to majestic scale. As Kobbe predicted, the "few cottages" bordering Deal Lake (or Loch Arbour) multiplied into a resort over the next few years. Interlaken, the land between the forks of Deal Lake, grew from a tract purchased for winter resort development to a self-sufficient community. Though Deal accommodated visitors in "several boarding houses: as early as 1834, serious growth began in 1894, when the Atlantic Coast Realty Company purchased the Hendrickson family farm lands for development. The land deal, made by Daniel O'Day, an executive for the Standard Oil Company and vice president of the National Transit Company, was considered "the largest real estate transaction" the Jersey coast had ever seen.  Around the turn of the century, the Atlantic Coast Company hired nationally known landscape architect Nathan G. Barrett to lay out the community. Barrett's plan, with wide streets, extensive lots, a railroad station and a golf course, catered to a wealthy clientele. The resort rapidly gained a reputation for excess, founded on the exploits of its eccentric residents. O'Day set the example by chartering a train to transport 2,000 friends to is house warming party, with entertainment supplied by the 69th Regiment Band of New York.
The future resort community conspicuously lacked boarding houses and hotels. More representative of the scale and style associated with Deal in the early 20th century is the Jacob Rothschild mansion, a 37 room, 14 bath, white stone building "of French Architecture."  Built by Arthur P. Gottlieb about 1908, the house belonged to William Durant, founder of General Motors Corporation, in the 1920s. By the next decade, Deal architecture was considered avant garde, as wealthy New York residents hired architects to experiment in a variety of revival, craftsman and Japanese-influenced styles. 
The history of the Deal Casino parallels the resort's evolution from a planned community to a wealthy borough. The Georgian-style gambling casino became the Deal Conservatoire of Arts and Theater in 1932, after it was purchased by Dorothy Untermann. In 1935, plays were performed in a theater judges "the swankiest summer theater in the world" by Variety magazine. The home of pianist Leopold Godowski at that time, the Deal school hosted an international crowd of musicians, artists and actors. By 1954, when an illness forced Untermann to sell the Conservatoire, fashions had changed; the city passed up her $15,000 price for the building, which could have been remodeled into an adequate, historically valuable municipal building.  Instead, the structure was finally purchased by a developer, who razed it and constructed three new homes on the property. A few years later, an $800,000 Casino with 475 bathhouses was built on Ocean Avenue to satisfy the requirements of modern bathers. 
During the Depression, while other Jersey Shore resorts sought alternative housing in apartments and duplexes, Deal zoning laws maintained its exclusive neighborhoods. As "estates with tile roofs are rapidly being replaced by modern homes, the wealthiest town in America per capita," remains financially secure.  Such building was encouraged by one of the lowest tax rates in Monmouth County. Driving through Deal today is like paging through a glossy real estate magazine; carefully groomed lawns highlight the individual mansions, ranging from late 19th century Colonial Revivals to contemporary "beach" homes. The scale of houses and lawns and manicured shrubs, sets Deal apart from the average speculative development. A fortress-like seawall, built to protect the property from the sea, also blocks any ocean view. No parking — and tacitly no public — is allow along this private stretch of Ocean Avenue.
