Doesn't plop for me. I got an error message:
ERROR: Method not found: 'Citizenmanager.CreateUnits'

Did I miss something obvious?

Using 81 Tiles and tried to build it out near the edge of the map, so valid for 81 tiles, but outside the 25 tile area. I build a lot of stuff in that outer part of maps and this doesn't act like other buildings I plop there.

Could "Nursing Homes for Senior Citizens" mod be the problem?

Hi heymegalodon ... I don't own any 3D Modelling software to create a block and customise it with a logo, sorry. And as Block Services are really Naylin's invention, I wouldn't want to 'steal' their idea by doing the same thing. But if you ask Naylin, they'll probably make one for you, as they already possess the templates needed for creating Block Services.

Do you have plans to do in the form of block service? It is quite difficult to choose the design for this controversial theme.
