Martin County's Best Industrial Story Is Aerospace and Marine, Not Warehouse Space

Martin County’s best industrial demand story is specialized manufacturing — anchored by Daher’s roughly 440,000-SF Witham Field aerostructures operation and a county economic-development strategy built explicitly around aviation, aerospace, marine and manufacturing.

Daher at Witham Field

Daher’s Stuart facility spans approximately 440,000 square feet across 44 acres and employs roughly 700 people. The company recently confirmed a long-term lease agreement for the site, which creates the possibility of additional investment and a future final assembly line for TBM and Kodiak aircraft. An anchor tenant of that scale, on a long-term commitment, with room to grow into a full assembly operation, is exactly the kind of demand signal that should reshape how we think about the surrounding industrial stock.

The county is building its economic strategy around this

Martin County’s Business Development Board explicitly emphasizes aviation, aerospace, marine and manufacturing as its target industries — this isn’t incidental to the market, it’s the stated strategy. That alignment between what the county is recruiting and what is already anchoring the market (Witham Field, marine services along the county’s waterways) makes Martin one of the more coherent niche-industrial stories in our territory.

Brokerage strategy

We’d build prospecting lists around aerospace suppliers, avionics companies, composite fabrication shops, precision machining operations, marine services businesses, and contractors supporting Witham Field directly. Functional buildings with three-phase power or usable yard space should command real attention here — that combination is scarcer than square footage alone, and it’s precisely what this tenant base needs.
