What this record tells you

Columbia Building Group Inc holds Florida licence CGC059448, 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 1997, which makes it one of the longest-held licences for the trade in this area. Roughly 19% of the 2,706 active general contracting licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2011. That is 29 years of continuous licensure.

Columbia Building Group Inc is one of 39 active general contracting licences registered to an address in Tequesta, so you have local alternatives to compare quotes against. Michael Joseph Sr Gruber additionally holds 4 other active Florida licences 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.
