HB 1335, passed by the state Legislature in 2021, funds research for the University of Washington and Eastern Washington University to identify restrictive covenants on private property and inform property owners. See the UW’s interactive map showing some of the subdivisions known to have been unlawfully restricted through deed provisions or restrictive covenants. This map is not exhaustive and currently contains King County properties only. The researchers are currently working on mapping restrictive covenants in Snohomish County.
Or you can do your own research. One option is to search the land title records maintained by Snohomish County Recording. These records are public, so you can search them for free. This can be a complex process and may require additional assistance from Snohomish County Recording. Research and copy fees may apply.
You can also review your owner's title insurance policy, which is typically issued at the same time the property is purchased. A title insurance policy identifies documents appearing in the public records that affect title to the property. Your policy may reference deeds recorded decades ago, or covenant documents affecting an entire subdivision. You may be able to request copies from the title company that issued your title policy, although a fee may be charged. You may also use the recording information in your title policy to get copies from Recording.
