Career Zenzinger was elected to the Arvada City Council in 2008. She became Mayor Pro Tem in 2011. Zenzinger was the campaign manager of Hudak's 2012 campaign.

In 2023, she played an important role in removing upzoning provisions from a major land use reform bill that Colorado Democrats were writing to address the housing crisis in Colorado. Zensinger wrote an editorial with Republican Colorado legislator Barbara Kirkmeyer that argued that the reform bill "should be amended to eliminate state control of local land-use planning." The bill subsequently was left to languish in the Senate, preventing its passage in the 2023 legislative session.
