The Public Records Act provides that a number of types of documents are exempt from public inspection and copying. In addition, documents are exempt from disclosure if any "other statute" exempts or prohibits disclosure. Exemptions outside the Public Records Act that restrict the availability of some documents held by Pierce County or its applicable agencies for inspection and copying include, but are not limited to, those set forth for counties and municipalities in the most recent list of other such statutes posted on the website of the Municipal Research Service Center, which is presently www.mrsc.org/Home/Explore-Topics/Legal/Open-Government/Public-records-Act.aspx, and which is incorporated herein by reference. The list is available for inspection and copying from the applicable public records officer. A list of applicable exemptions may also be found in the Public Records Act Deskbook, published by the Washington State Bar Association.

Pierce County and its agencies are prohibited by statute from disclosing lists of individuals for commercial purposes.
