Much of law school is focused on finding and interpreting federal and state laws, though not all (ask any dog-bite memo composer!).  This makes sense pedagogically, but from a practical standpoint we more often interact with our local laws. Municipal codes and ordinanaces govern many aspects of our everyday lives. Topics covered by ordinance often include zoning, public health and safety, codes of conduct, and building codes.  In fact, many attorneys choose to specialize in munipal law, in both private practice or representing local munipalities  Despite their proliferation, researching munipal codes can be tricky, here are some resources to get you started.

The Wisconsin State Law Library maintains an index of Wisconsin city and county ordinances and codes, with links to those posted online (nearly half are avilable!). If you are looking for ordinances for a municipality that has not posted them online, the best starting point is to contact the local municipal clerk. Most city clerks will provide a way to view the ordinances in person, or will mail or email copies of specific ordinances.

What about municipality outside of Wisconsin? I always advise beginning research with a research guide (save time and let the experts guide the way).  This research guide from the Library of Congress outlines the best strategies and resources for both current and historical historical codes from accross the country, as well as links to secondary sources. Georgetown Law Library also maintains a research guide on municipal codes with links to several databases.

Speaking of databases, there are several, both free and vendor-based, that collect and index ordinances and codes. Municode is a free database that will link you to several codes from all fifty states for any municipality that has opted in, it can be found here. Additionally, the CPC Code Library covers 25 U.S. states, tribal governments, and special districts, as well as parts of Canada. If you have access to vendor databases such as Lexis+ and Westlaw Precision, each have collections of municipal law resources, including briefs, proposed legislation, and secondary sources.
