This comprises the codification of the Ordinances of the Township of Smithfield. Smithfield was originally settled in 1725 and was incorporated as a Second Class Township in 1742 while part of Bucks County.

The Code of Ordinances of the Township of Smithfield was prepared by Penns Valley Publishers and adopted by the Board of Supervisors on April 26, 1994, by Ordinance Number 128.

The Code contains four parts which are (1) the valid current ordinances of the Township of Smithfield contained in Chapters 1 through 30, (2) the Appendix which lists by abstracted title all ordinances of a temporary or "one time" nature, (3) the Key to the disposition of each ordinance ever enacted by the Township of Smithfield, and (4) the Index which is an alphabetical arrangement of subjects.

In the Code, each Chapter is separated by a divider tab, and specific ordinances can be located by subject on the contents page at the beginning of each Chapter. The Index may also be used to search for a subject when one is looking for general information on a particular subject, or if it is not known in which chapter the subject might be found. The Appendix consists of several general categories containing a chronological listing of short subject descriptions along with a reference to the original ordinance and its date of enactment if known.

The Key to disposition indicates what action has been taken by the codifiers and the Board of Supervisors with regard to every ordinance ever enacted. An ordinance has either been (1) specifically repealed, (2) superseded by another ordinance, (3) is located in a chapter of the code book, or (4) is located in the appendix. Annual tax rate and budget ordinances are located only in the Key. The Key is a cross reference to the original ordinance books of the Township of Smithfield, and to the location within the Code of each ordinance by number.
