Its association with Thomas M. Callahan, founder of Golden Rule Stores is more significant however. Callahan lived in and had an office in the house from 1897 until 1938.

Penney Company.”“Soon after Callahan bought the Sweeny house, he began to make improvements. He added hot water heat and a four-room, two-story addition on the south rear of the house where he located his office on the first floor.”“The house's wraparound porch and porte cochere were added in 1904; the interior was redesigned in 1908, and its grounds were expanded by purchase of adjacent land, allowing for extensive landscaping.”"During his years in Longmont, Callahan was very active in local civic affairs and fraternal organizations. He served as an officer and/or director of several local banks and was involved in the formation of the Arbuckle Ditch Company, which remains an important water source for Longmont and the surrounding farm community. 6 In 1938 Callahan and his wife moved to Reno, Nevada, at which time they donated their house to the city of Longmont for exclusive use by women f s groups and clubs for meetings and special events.

In 1907, the first fire station was torn down to make room for the second station built in the same location in 1908. When the Terry St./11th firehouse was designed (currently Longmont Fire Station #1), the front was designed to mimic the front of the fire house on 4th/Coffman. Because of this design, the new fire house was able to house the early 1900 fire pole and bell once used to get early firefighters from the second floor to the street level.
