The Denman Museum & Archives draws its mandate from the constitution of the Denman Museum and Seniors Society. The Museum and Archives is a standing committee of the DSMS chaired by a director for Museum and Archives. The budget is allocated by the DSMS Board supplemented by earned revenues from M&A activities and project grants. 

In October 2023 work has been done on the museum roof to repair the aging roof and address leaks which have endangered the collections. The museum wishes to thank the Government of Canada for partial funding of this project through Heritage Canada. The final bit of the work will be completed when weather permits.
