I've felt some of this since I got married and had kids, but I've chalked it up more to the increased social connections than any kind of 'permanence'. I know my neighbors a lot better because my kids know their kids, or I see them at the school, etc. I owned a house for 10 years before getting married and didn't really have any neighborhood connections, so I don't think that just buying a house is enough.

Also, it helps in a lot of unexpected places, like at work. Now I have a lot more in common with managers and above than when I was a single guy. I'm very convinced that part of my recent jump in career progression has been this additional connection. Suddenly everyone sees me as management material, for better or worse.

You bought a house. That implies you moved to a suburban area. Having owned a house in a suburban area in a transitory time of my life, and lived in a city for what I thought was settled down - no, there's no question, it was the suburban lifestyle that allowed meaningful connections.

What do you mean by permanent? Having bought a house and married? Or creating a static environment for a child to grow up?
