The City and County of Denver has tapped a familiar face to run its property tax shop, naming longtime staffer Jonathan Norloff as the next county assessor. Norloff, an appraiser in the Assessor’s Office since 2012 who has served as deputy county assessor since 2024, is set to take over the top job next Sunday. He steps in for Keith Erffmeyer, who has left for a statewide role overseeing property tax administration.
In a Department of Finance statement reported by the Denver Gazette, Chief Financial Officer Nicole Doheny said the city was "thrilled to promote Jonathan Norloff" and highlighted his tenure and technical know-how. According to that report, Norloff holds professional ad valorem appraiser licensures and a bachelor’s degree in business administration from McPherson College. Norloff said in the release that he was honored to take on the role and thanked staff and partners for their support.
From city hall to the state house
Erffmeyer exited the Assessor’s Office after serving as Denver's county assessor to take a position with the state. The Colorado Department of Local Affairs confirmed in a press release that he began his state duties earlier this month and will serve as the state's Property Tax Administrator, citing his more than three decades of experience in Denver's assessor ranks. His move prompted Denver leaders to keep it in the family and elevate an internal successor in an effort to preserve continuity in valuations and appeals.
Why the assessor's job matters
The Assessor’s Office is responsible for locating, identifying, and appraising all real and personal property in Denver so that tax burdens are shared fairly under state law. Denver rolled out a new property research platform last year that gives residents access to valuation details and records, tools the new assessor will now oversee, according to the City and County of Denver. Those services will remain the primary channel for residents with questions about value notices and appeals as Norloff settles into the job.
Norloff steps into the post with more than a decade inside the office and credentials city leaders say will be useful during the next round of annual valuations. Officials expect the transition to be smooth and say routine services should continue without interruption as the new assessor gets up to speed.
