21 Construction, Inc.

What this record tells you

21 Construction, Inc. holds Florida licence CGC1527422, 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 2019, which makes it an established licence for the trade in this area. Roughly 56% of the 5,272 active general contracting licences based in the Miami area were issued earlier than this one, and the local median sits at 2016. That is 7 years of continuous licensure.

21 Construction, Inc. is one of 3,292 active general contracting licences registered to an address in Miami, so you have local alternatives to compare quotes against. Jose Luis Castillo additionally holds 2 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 08/31/2026. 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.
