Z Construction Co., LLC holds Florida licence CGC1505709, 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 2003, which makes it a long-held licence for the trade in this area. Roughly 20% of the 1,190 active general contracting licences based in the Sarasota & Bradenton area were issued earlier than this one, and the local median sits at 2014. That is 23 years of continuous licensure.
Z Construction Co., LLC is one of 511 active general contracting licences registered to an address in Sarasota, so you have local alternatives to compare quotes against. Alan P Zirkelbach 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 08/31/2028. 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.
