Radius Development Group, LLC

What this record tells you

Radius Development Group, LLC holds Florida licence CGC1535121, a CGC classification which authorises work as a certified/registered general contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2023, which makes it a relatively recent licence for the trade in this area. Roughly 76% of the 1,770 active general contracting licences based in the Tampa area were issued earlier than this one, and the local median sits at 2013. That is 3 years of continuous licensure.

Radius Development Group, LLC is one of 946 active general contracting licences registered to an address in Tampa, so you have local alternatives to compare quotes against. Jeremiah Quinn Sr Calkins additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2028. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
