With the implementation of Enhanced 911 emergency telephone service, Lancaster County has established an addressing system which identifies all occupied structures in the county by house or building number and street name. For those individuals and businesses who are provided rural carrier delivery service by the United States Postal Service, this location identification also serves as the mailing address.
Road names are given to all state maintained roads in the county and all subdivision and private roads which serve three or more occupied structures. The majority of the road names currently in use were assigned in 1993 by a ten-member citizen committee appointed by the Board of Supervisors.
House numbers are generated by a computer program that assigns one number for each 5.28 feet of road frontage with even numbers on the right hand side of the road and odd numbers on the left side of the road. The starting point for the address range for each road is "1".
Buildings within the town limits of Kilmarnock are addressed according to a scheme which pre-dates Lancaster County's E-911 implementation. Therefore, addresses for buildings in the town of Kilmarnock are assigned at the town office.
Numbers for new homes and businesses are created by county staff during the building permit application process. A Street Address Request Form must be filled out and submitted with the building permit application.
All building numbers must be posted on the building or at the driveway entrance if the building is not visible from the road. Numbers must be at least three inches high.
