Mark Frederick Keller

What this record tells you

Mark Frederick Keller holds Florida licence CGC031719, 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 1984, which makes it one of the longest-held licences for the trade in this area. Roughly 3% 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 42 years of continuous licensure.

Mark Frederick Keller is one of 73 active general contracting licences registered to an address in Odessa, so you have local alternatives to compare quotes against.

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.
