Municipal Codes: A Beginner’s Guide

This post was co-authored by Barbara Bavis and Robert Brammer, Legal Reference Specialists.

Although we are likely more frequently asked about federal laws here at the Law Library of Congress, we do receive quite a number of reference requests concerning state and local law.  Of these non-federal requests, some of the more challenging questions deal with laws found in municipal codes.  This challenge arises largely from the difficulty in finding copies of municipal codes for our patrons, as there is no one singular clearinghouse for all municipal codes.  We hope that this Beginner’s Guide can help those patrons performing research regarding municipal ordinances to more easily sort through the resources available, and find the information they need.

A note before we begin—to make sure we are clear about what we mean when we say “municipal codes,” we are referring to the collection of laws passed by a local governing body (often of a county, city, village, township, or other similar governmental subdivision).  The laws themselves can be referred to by many names, including “ordinance,” “bylaw,” and “measure,” among others.  As long as they do not conflict with the laws of the state in which the municipality is located, these ordinances have the “force and effect of law” in the municipality.[1]

Most of the questions we receive regarding municipal codes ask about the current form of the law.  Luckily for these researchers, a large number of current municipal codes are freely available online via several publishers’ websites.  Some of the more popular such websites include:

While none of these sites contain all of the municipal codes in the United States, they provide a helpful (and free) jumping off point for legal researchers in this area.

Sources of Older Municipal Codes

For those researchers who seek older, superseded versions of municipal codes, the research process becomes slightly more complicated.  Old versions of municipal codes may be found in multiple locations.  First, we suggest focusing your search in the geographical area in which the municipality is located, as institutions in that area are more likely to have the documents you seek.  Thus, you may want to start your search at the local public library for the municipality, and/or an academic, governmental, or other public law library in the municipality’s state.  Some researchers have also found success contacting the municipality’s clerk’s office, as well as the official archives for the municipality’s state.

Further, you can use a catalog that pulls from a broader collection or set of collections, such as the Library of Congress or WorldCat catalogs. To perform a more targeted search, simply use the subject heading “Ordinances, municipal” in connection with the name of the municipality you are researching.

Sample Municipal Codes and Other Guidance

For those researchers seeking information about trends in municipal ordinances, or for municipalities wishing to find out more information about laws that could improve their area, there are organizations that provide guidance regarding research supporting and language involved in drafting municipal codes:

Secondary Sources

Secondary sources are not law in and of themselves,  but may help a researcher unravel and understand an unfamiliar area of the law. The secondary sources listed below are varied; they will help you understand the basics of municipal law, provide you with references to interpretive cases, and will equip you with useful forms.

We hope this Beginner’s Guide is helpful. If you have any questions about researching municipal codes, please contact us through our Ask A Librarian service.
