AT&T Fiber in any condos in Louisiana?

It probably depends on what kind of condo. There are condos that are like townhouses (at least in Houston) where a fiber company can reach individual units externally, and condos that are more like apartment complexes.

The latter sort usually has management that has agreed to a captive agreement for Xfinity, etc. and contractually prohibit the condo association from allowing competitors to run fiber.
