Housing is a local, or at least federal matter. EU is about interstate commerce. The advertising/consent regulations are about commerce so it makes sense. Pan-EU housing regulations wouldn't as those are typically in the domain of each country/locality.

eu already affects the housing market with green regulations and housing standards, energy standards, policy on residence visas etc.

and communications was not among its mandates either

You’re really not in a position to speak for all Europeans. You’re painting a complex issue with a broad brush, and of course painting it in such a way that it supports your position.

The European parliament is made of deputees elected from each European countries, so why would it not be ?
