What this record tells you

Development Services of Florida, Inc. holds Florida licence CGC1520330, 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 2012, which makes it a long-held licence for the trade in this area. Roughly 43% of the 1,000 active general contracting licences based in the Naples area were issued earlier than this one, and the local median sits at 2015. That is 14 years of continuous licensure.

Development Services of Florida, Inc. is one of 937 active general contracting licences registered to an address in Naples, so you have local alternatives to compare quotes against. Mark D Tolson 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.
