How can I find the builder for a particular house?

[Hans Baum]

There are a number of great new construction builds around Philadelphia, and I'd like to reach out to the builders. How do I go about finding the builder for a particular address?

[Kevin M.]

The easiest way would be to look up the permit history for the new construction. 

Type the address in to; https://li.phila.gov/property-history

This will give you the name of the contractor who pulled the respective permits for the work including the underlying Building Permit. You can then search for information about the contractor here;

https://li.phila.gov/contractor-lookup

In theory this will lead you to the builder. 

In reality it may lead you to some kind of shell company with no contact info or 'friend of a friend with a license', but it's at least a good place to start
