Be aware that many owners use property management companies, which I don't think is public record. But getting the owners name (may not even live in the area) could help you find out who is managing your building. If the property is being managed by a company you could check with the BBB (Better Business Bureau) to see if complaints have been filed in the past and to file one of your own.
Yes, property ownership is a matter of public record, and many US counties have property registry databases that are online. They are most often found on the website of the county clerk's office. If your county does not have online access to public records, you will likely have to visit the county clerk's office in person.
