Martin Construction of the Keys

What this record tells you

Martin Construction of the Keys holds Florida licence CGC1539452, 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 2025, which makes it one of the newer licences for the trade in this area. Roughly 92% of the 230 active general contracting licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2012. That is 1 year of continuous licensure.

Martin Construction of the Keys is one of 61 active general contracting licences registered to an address in Key West, 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.
