Certain Custom Lots that Refuse to Grow

[ncamferdam 1,522]

I know that this is a fairly frequent issue for people to ask about around here, and I think that I'm generally familiar with the various issues at play (capacity and growth stage need to be right, demand needs to be high enough, building styles need to be set correctly), but it seems like I'm following all suggestions and certain buildings just refuse to show up.

To control as many variables as possible, I've been following Cori's process here to manipulate building styles:

 

I know I'm following it correctly, because for certain buildings I'm able to set up an override, enter the game, and immediately get that building to appear while all other RCI is blocked. It works for some buildings, but for certain lots it just doesn't. They refuse to grow.

At this point I'm mainly trying to find intelligent avenues of further investigation. Is there anyway just by looking at the files to see if a lot can grow in-game? Any properties that have been known to block growth? Should I take one of the problem lots, change all of the properties to exactly match a lot that has successfully grown?

Just trying to figure out what else I can tweak.
