ApartmentRatings maintains a database of tenant-generated reviews of apartment buildings. According to the site’s homepage, the site currently contains more than 1,200,000 reviews of apartments and apartment complexes. In addition to reviews, the site features a database of building features, user ratings, and a database of tenant-reported average rental prices called "What the Neighbors Pay."

The site also has a Google Maps-based registered sex offender database, and a question-and-answer feature that allows apartment hunters to ask questions about particular apartment buildings they are interested in, and have their questions answered by apartment renters currently living in the building in question.
