Middle Keys · Monroe County
Structural Engineer
in Marathon
City of Marathon structural engineering — canal homes, Boot Key Harbor work, and Middle Keys commercial sets stamped for municipal review.
The Location
Engineering in Marathon
Marathon spans Vaca Key, Boot Key, Knights Key, Grassy Key, and Fat Deer Key — anchored by Sombrero Beach, Boot Key Harbor, and the Seven Mile Bridge at the city's southern tip.
Since 1999 the City of Marathon has run its own LDRs and building portal — separate from Monroe County, with Boot Key Harbor overlays that county templates omit. Numbered-street canal additions, pool structures, and commercial rebuilds in Marathon need City cover sheets, local flood callouts, and sealed PDFs formatted for municipal intake. We design Marathon structural sets to that single municipal path from the first sketch, whether the job is a hurricane retrofit or Boot Key Harbor commercial framing. Restaurant and retail rebuilds inside Marathon city limits use the same City portal formatting so commercial reviewers are not handed a Monroe County package by mistake.

Permitting
Permits & Codes in Marathon
Marathon permits go through the City portal, not Monroe County's Upper or Lower Keys offices. Plan sets need City cover sheets, flood-zone callouts keyed to Marathon's local maps, and — for Boot Key Harbor work — marina and working-waterfront notes that county templates omit.

The Engineer
Plans stamped by our licensed PE
Every set of drawings that leaves this office carries our Florida PE seal (PE #79269) — no sub-consultants, no stamp-for-hire. Our firm has engineered more than 6,500 projects, with 11+ years specifically in the Florida Keys environment.
That means your Marathon project benefits from code fluency built specifically around Monroe County and incorporated-city review patterns — not a firm adapting a generic Florida template for a Keys lot.
