David Alan O Donnell

What this record tells you

David Alan O Donnell holds Florida licence MRSA5335, a MRSA classification which authorises work as a licensed mold assessor. An "R" prefix means the licence is registered, which limits work to the local jurisdictions that accepted it rather than the whole state.

This licence was first issued in 2025, which makes it one of the newer licences for the trade in this area. Roughly 87% of the 134 active mold inspection licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2018. That is 1 year of continuous licensure.

David Alan O Donnell is one of 68 active mold inspection licences registered to an address in Jacksonville, so you have local alternatives to compare quotes against. David Alan O Donnell 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 07/31/2028. 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.
