The ACRIS website is a free service that allows anyone with internet access to obtain public property records covering all of New York City’s five boroughs.

Some common types of documents that can be located on ACRIS are deeds, mortgages, liens, easements, satisfaction of mortgages, and many others – all free of charge to the public. However, it should be noted that any documents filed prior to January 1, 1966 are not available on the ACRIS website; for those documents you would need to make an in-person visit to the City Register’s office in the county in which the document was filed. ACRIS is also a helpful tool in identifying a property’s block and lot, which is often needed but hard to find.

Overall, ACRIS is tremendous resource for those looking to research, view and even print out property records in New York City.
