MRSC's custom search options help you find the answers you need beyond the MRSC website, allowing you to search multiple city/county codes or websites across Washington State at once.

Combined City/County Codes Search

Below are instructions on how to search multiple city and county codes at once.

Most Washington city and county codes are hosted by Code Publishing, with a smaller number being hosted by Municipal Code Corporation. A few others are self-published or hosted by Sterling Codifiers, in which case they must be searched individually.

For a complete list of the codes that are published online, as well as which codes are hosted by which company, see our Washington City Codes and Washington County Codes.

Code Publishing

You can search Washington codes hosted by Code Publishing through Google, Bing, or other search engines by typing in your search term followed by site:codepublishing.com/wa. For example: "surface water" site:codepublishing.com/wa.

Municipal Code Corporation

Municipal Code Corporation has a paid search option. You can also search Washington codes hosted by Municipal Code Corporation through Google, Bing, or other search engines by typing in your search term followed by site:library.municode.com/wa. For example: "surface water" site:library.municode.com/wa.
