Hi Daniel.

Have you tried the Orange County Property Appraiser? Its platform is one of the best I've ever tried. It provides, among several visual tools, direct access to Plat and Sketches.

Just a heads up: that data is for tax assessment purposes, not a legal survey. If you need the dimensions for something official (boundary disputes, fences, permits), you'd want a boundary survey from a licensed Florida surveyor.
