Tapped a steel beam(balcony support) going .5-1kmh trying to get out of my driveway

So I just moved in to my house yesterday evening, met the neighbors all is good.

This morning about 0550 I was having difficulty backing out of my very tight parking area.

I ended up bumping into a steel support beam on my neighbors house.

The speed was negligible, like .5-1kmh. once I finally straighted out I got out to check the beam and my bumper, of course there was no damage in either whatsoever.

Upon confirming no damage of any kind I continued on to work, especially considering how early in the day it was I decided it wasn't worth disturbing my neighbor.

Now I'm kind of paranoid, unsure if I made the right decision. When I get home later should I chat with my neighbor and apologize? How should I proceed?
