[22] New Milford was authorized to be incorporated as a borough on March 11, 1922, from what remained of Palisades Township, subject to approval in a referendum (which took place on April 18, 1922).

[2][3] The borough borders the Bergen County municipalities of Bergenfield, Dumont, Oradell, River Edge and Teaneck.

The mayor can veto ordinances subject to an override by a two-thirds majority vote of the council.

[43][44] As of 2023[update], the mayor of New Milford is Democratic Michael J. Putrino, whose term of office ends December 31, 2026.

[4][45][46][47][48][49] In January 2019, Matthew Seymour was selected from three candidates nominated by the Democratic municipalcommittee to fill the seat expiring in December 2020 that was vacated earlier that month when he took office as mayor.

[50] Democrats took control of the council in the November 2012 general election, as incumbent Austin Ashley won reelection while running mate and former council member Michael Putrino was elected again after having served two previous terms of office.

Incumbent Republican Howard Berner and running mate Peter Rebsch, a former council member, fell short.

[52] Peter Rebsch was appointed in June 2011 to fill the vacant seat of Council President Keith Bachmann, who had resigned from office; Rebsch served until November 2011, when voters chose a candidate to fill the balance of Bachmann's term that expired in 2012.

After counting absentee ballots, Duffie and Grant won the two three-year council seats, edging Republican Scavetta by 10 votes, and started their terms in January 2012.

Ashley defeated Darren Drake by 39 votes for the remaining year on the unexpired term of Ann Subrizzi that had been filled on an interim basis by Peter Rebsch, and took office after the election.

Republican challenger Ann Subrizi (2,433 votes) ousted 14-year Democratic incumbent, Frank DeBari (2,120).

The Republican challengers for Council defeated both incumbents, with Dominic Colucci (2,328 votes) and Diego Robalino (2,285) unseating Democrats Michael J. Putrino (2,210) and Arthur E. Zeilner (2,115).

These result gave the Republicans a 4–1 margin, with Ann Subrizi's seat on the Council left vacant.
