After retiring as vice president of [[W. & J. Sloane]], Walter Law moved with his family to the present Briarcliff Manor. He bought his first {{convert|236|acre|ha}} in 1890,<ref name="1939history"/> and then quickly expanded his property, buying about forty parcels in less than ten years; by 1900, he owned more than {{convert|5000|acre|sqmi}} of Westchester County.<ref name="glassglory"/><ref name="society"/> Law developed the village, establishing schools, churches, parks, and the [[Briarcliff Lodge]]. His employees at Briarcliff Farms moved into the village, and the population grew enough to encourage Law to establish the area as a village. A proposition was presented to the supervisors of Mount Pleasant and Ossining on October 8, 1902, that the area of {{convert|640|acre|ha}} with a population of 331 be incorporated as the Village of Briarcliff Manor,<ref name="1952history"/>{{rp|page=14}} and the village was incorporated on November 21.<ref name="Changing Landscape"/>{{rp|page=43}}<ref name="pamphlet"/>

The [[Tudor Revival]]-style Briarcliff Lodge was opened in 1902 as a premier resort hotel. It was surrounded by Walter Law's dairy barns and greenhouses, and hosted numerous distinguished guests, including [[Franklin D. Roosevelt|Franklin]] and [[Eleanor Roosevelt]]. The lodge held the Edgewood Park School (1936–1954) and [[The King's College (New York)|The King's College]] (1955–1994)<ref name="Segal"/> before it burned to the ground on September 20, 2003.<ref name="LodgeBook"/>

The [[Briarcliff Manor Fire Department]] was founded on February 10, 1903, from Briarcliff Manor's first fire company, the 1901 Briarcliff Steamer Company No. 1.<ref name="1939history"/> Scarborough was incorporated into Briarcliff Manor in 1906, and the Police Department was organized two years later. The Village Municipal Building was built in 1913 and was opened on July 4, 1914. The high school opened in 1928, and in 1946, the People's Caucus party, an organization which calls out interested residents for candidacy, was created.<ref name="1977history"/>{{rp|page=88}}<ref name="Centennial"/> Briarcliff Manor celebrated its semicentennial celebration from October 10–12, 1952, publishing a book about the village and its history; that year, the Crossroads neighborhood of 84 houses was completed.<ref name="1952history"/>{{rp|page=i}}

In 1953, [[Todd Elementary School]] opened to free space at the Law Park grade school.<ref name="Changing Landscape"/>{{rp|page=153}} The [[New York and Putnam Railroad#History|Putnam Division]] of the [[New York Central Railroad]] was discontinued in 1958,<ref name="Putnam1958"/> and the following year the [[Briarcliff Manor Public Library]] opened in the former Briarcliff Manor train station. The village's first corporate facility (part of [[Philips Research]]) opened in 1960. In 1964 the new Village Hall opened, replacing the Municipal Building. The present high school opened in 1971 to ease the large enrollment at the grade-school building.<ref name="Changing Landscape"/>{{rp|pages=153–4}} In 1980, [[Pace University]] began leasing the middle-school building, and the middle school was moved to a portion of the new high-school building. The grade-school building was demolished in 1996, and a [[retirement home]] was built on its site the following year. The village celebrated its centennial in 2002, which involved celebratory events.<ref name="Centennial"/> A two-story addition to the village library was built in 2009, and the original portion was renovated to become the village's community center in 2016.<ref name="LibraryHistory"/><ref name="WVCC"/>
