Although the city's population was increasing, the hamlet's original residential structures remained largely unchanged. This resulted in the construction of several commercial buildings, including the William Bailey House. These structures were later modified to accommodate the growing population. In the 1990s, three large buildings were erected on the grounds of the William Bailey House, which compromised the setting of the Second Empire style house.
