Our apartment block in Helsinki has a pelastustie that is regularly unusable because of people parking in front of it. Where can I report such parking offenses?

I tried googling, but it brings me only to the police. Is this the right place to report these? Because they are probably not counted as “crimes”, or are they?

And can I just take pictures of the offending car for proof?

In Germany, there is a useful Webservice that helps with the involved bureaucracy. Does something like this exist for Finland?
