Surveying supplemented Yates' attorney's income as he made a number of important land maps during the 1760s. He drew the first civilian
map of Albany in 1770. He also relied on
patronage from the Albany Corporation through his uncle, alderman
Abraham Yates Jr. In 1771, he was elected to the Common Council as an
alderman for the second ward. In those years he served on a number of committees, provided legal advice, and stepped forward to compile and issue the first published version of the "Laws and Ordinances of the City of Albany" in 1773. In December 1787, Yates and John Lansing wrote a letter to Governor Clinton urging opposition to the new
Constitution. Yates's personal notes from the Philadelphia convention were published in 1821. After the Poughkeepsie Convention ratified the Constitution with an accompanying request for amendments to protect individual liberties, Yates pledged his support as a matter of patriotic duty. In 1789, he ran for governor against George Clinton with the support of the
Anti-Federalists, who viewed him as a reasonable, potentially kindred spirit who was not from a wealthy family. He was defeated by Governor Clinton. Approached by the Federalists again in 1792, Yates refused to run citing the financial drain caused by past politicking. In the
gubernatorial campaign of 1795, considerable sentiment existed for Yates's candidacy as he was firmly established in the center of the former Anti-Federal party. John Jay defeated him in a close election, effectively ending Yates's political career. By then, he already had devoted himself to the law. In September 1790, Yates was chosen
Chief Justice of the New York State Supreme Court. He served until the mandatory retirement age of sixty in 1798. Unlike many "new men of the Revolution," he did not attain great wealth and retired to his middling Albany home. ==Personal life==
