Property ownership listings are public records available to everyone, which means you shouldn't have much trouble finding out who owns a rental property. Simply have the address in question ready. You won't usually need any other information. If the an employee at the assessor's office wants a specific reason for your request you can oblige the assessor's staff if you want, or you can remind him you have no obligation to do so as the records are public.
Step 1
Visit your county assessor's website. You can search for an assessor's website by going to your county government's homepage, or by typing your county's name, such as "King County," followed by "assessor's office," all without quotation marks, into a search engine. Make sure you get the website for your county rather than a county in another state with the same name.
Step 2
Follow the instructions on the assessor's website to submit your public records request. These websites vary from county to county, so there is no universal process. If your county has a form for specifically requesting this kind of information, use it. Otherwise, use their general "contact us" form or look for a contact telephone number.
Step 3
Look up the county assessor's telephone number in the phone book as an alternative to using the Internet. To find the number look in the governmental listings under "county" or "assessor." If you can't find it, call the general county phone number to get the specific assessor's office number.
