Who runs Denville Township
Denville operates under the Faulkner Act using the Mayor-Council Plan F. The mayor is elected at large to a four-year term and serves as chief executive, while a seven-member Township Council acts as the legislative body. Mayor Thomas W. Andes has held the office since 2012, and his current term runs through Dec. 31, 2027. Business Administrator Steven Ward oversees daily operations of the municipal departments.
The 2026 Township Council, according to the township’s council page:
- Glenn R. Buie, Council President, Ward 3
- Chrissy Kovacs, Ward 1
- Adrienne Zimmermann, Ward 2
- Gary Borowiec, Ward 4
- Mark Venis, at-large
- Robbie Simpson, at-large
- Lou Maffei, at-large
The four ward seats run through 2029 and the at-large seats through 2027, so the Morris County Clerk lists no local township election in Denville on Nov. 3, 2026. Council agendas and minutes are posted on the township’s agendas page.
