When I lived in New Jersey, the company that repaved my 20-year-old blacktop driveway said not to seal coat (and reminded me that public road crews don’t even do this to shared city streets) and I wonder whether the local company is just trying to guarantee a job for themselves.

It’s very unlikely that well-made, paving surfaces will need sealing this early on. Do a little investigating by making an appointment with the township’s engineer (who would’ve had to approve your community’s paving plan in the first place) and see what they think of the seal-coating proposal you’ve received. The engineer should be able to review your site’s plans and determine an appropriate maintenance schedule for the development’s roadways. This’ll also give you the opportunity to dig into plans for the overall site, and determine any particular areas where eventual maintenance attention may be required.
As for driveways, Seal-coating typically lasts from two to eight years, depending on climate and surface use. Whether you need it or not, depends on how well your road was put down in the first place. Since driveways are not typically as thick and sturdy as paved streets, they do tend to need more TLC as time goes by.
