Below is a public website with tax record information of all units, not just builder sales.
Please keep in mind that it takes about 3-4 months for the sales data to update in the public tax record websites.
You can also go to the Tax Collector's office in City Hall with the lot & block # of the building you have questions about and they can provide you with tax and last sales information.
Please let me know if you have any additional questions. I'll be happy to assist.

As many have said here you really should look to a real estate agent who is familiar with the area you are inquiring about. The tax records actually does show resale figures however, the information can take months to become public, and if it's a very large condominium development project it could take even longer. In this case, you'll want to have the real estate agent research the Multiple Listing Service for data on the building counting that there were transactions listed on the MLS.
If the building was sold by the developer's sales office privately without being on the MLS, then this information is a little harder to come by. You might have to try contacting the sales office directly and asking them what specific units traded for.
If they aren't willing to share the information with you then you'll have to go directly to the city and research the information to look up recent sales.
I hope all of this advice was helpful!
Best of luck
