The growth of services in the community has significantly affected life in Farr West. In 1900 the first post office was established in Farr West. Rural free mail delivery began in 1905. Also in 1905, phone service was brought into the community. Electricity was made available on 29 May 1916. The Farr West Sewer Improvement District was established on 4 January 1968. Natural gas was brought into the community in August 1958. Bona Vista Water Improvement District provided culinary water in 1958; Pine View Water Systems brought a secondary water system to the area in 1982.

The earliest business in Farr West was built in 1862. It was called the Prairie House, and was a tavern that primarily served travelers who were on their way to the gold mines in Montana. In 1869 the Union Pacific Railroad laid a line through the eastern part of Farr West, a line later called the Ogden Shoreline. In 1874 William Rawson opened the first general merchandise store in the town. For many years, new businesses remained in operation only a relatively short time. Only in recent years have more permanent business activities become established. At the end of 1992 the city had issued licenses to sixty-one business, which range in size from the large Smith and Edwards variety story to small businesses operating from home sites.

Road improvements have had a significant impact on community development. The earliest unimproved roads were dusty in dry weather and filled with ruts and difficult to traverse in bad weather. Applying gravel to the roads improved their condition markedly, but asphalt and concrete were not used in local roads until around 1930 (the year West Harrisville Road was paved).
