In the 2014 municipal elections, Boucard once again joined the UMP list led by Meslot and was nominated for spot 7 of 45. Meslot won by a large margin in the second round after Christophe Grudler withdrew following the first round, securing 47.38% of the vote against the Socialist Party (PS) list led by Etienne Butzbach with 31.96% of the vote, the National Front (FN) list led by Marc Archambault with 10.43% of the vote, and the MRC list led by Bastien Faudot with 10.21% of the vote. It was the first time in 37 years that the city was won by the right, having been governed by the left since 1977. As municipal councillor, he was charged with the children, youth and associative life portfolio, and as vice president of the agglomeration community of Grand Belfort, received the housing and urban policy portfolio. He was also an administrator at the office of public housing and public works company of Territoire de Belfort. He was selected as a UMP alternate in the 2015 departmental elections within the canton of Belfort 3, but MoDem candidates Julie de Breza and Christophe Grudler defeated the UMP ticket of Florence Besancenot and Damien Meslot in the second round, receiving 53.50% of the vote against their opponents with 46.50% of the vote. In April 2016, Boucard was designated departmental secretary of The Republicans (LR) in Territoire de Belfort. On 6 November 2016, Meslot confirmed that he would not seek a fourth mandate in the National Assembly, and Boucard was subsequently confirmed as the LR candidate in Territoire de Belfort's 1st constituency in the 2017 legislative elections a week later. He was officially invested as a candidate by the party on 14 January 2017. Although Meslot chose not to run for re-election and instead remain mayor of Belfort, he was still chosen as Boucard's alternate. In the first round on 11 June, Boucard came in second with 23.70% of the vote, with Christophe Grudler, candidate of the MoDem supported by La République En Marche! coming in first with 31.83% of valid votes. Boucard and Grudler advanced to the second round and the other candidates were eliminated; Jean-Raphaël Sandri of the National Front received 17.50% of votes, Anaïs Beltran of La France Insoumise secured 12.17%, and Bastien Faudot of the PS and MRC garnered 9.10%.
