Will Vinegar Harm Paint on Stucco?

I am in a bit of a dilemma. A building that we clean is having an issue with stray cats marking their territory on the stucco, and the urine smell is seeping into the building through the AC/Heating air vent. The owner of the building called me today and asked if I could remedy this problem for him. I have found numerous natural solutions online concerning what to spray to hopefully prevent cats from spraying; vinegar being the most common solution, but what my concern is, could the vinegar harm the paint in any way. The owner just had the building painted within the last year so I don’t want to spray anything on there that might stain or bleach out the paint. Could anyone give me a little insight, I’ve looked online and I can’t find the information I need.
Thanks so much!

I think it is very unlikely. I have used vinegar, diluted and full strength to clean a lot of things, including painted walls. I've yet to have vinegar stain or discolour anything.

@AmbivalentFriability Great! I had read that vinegar could harm carpet, so I wanted to make sure that it was ok on paint. Thanks so much!

If you find that vinegar isn't enough, you could look into products by Nature's Miracle. They contain an enzyme that actually breaks down the urine.
I've tried to clean dried-on dog pee off a wall (at an animal shelter) and vinegar did not work, even when I mixex it with baking soda. To be fair, it was many dogs peeing on the same spot and who knows how long it had gone without a proper cleaning.
