Default Why would somebody seal this vent?

Anybody know why someone would seal these garage vents with fill-a-gap? I remember the inspector for this house said it's not to code, not to mention it's aesthetically unpleasant. Neighbor looks like they just ducktaped a a piece of screen inside of it. I see "Foundation Vents" on google but they look like when they're open they'd allow bugs into the garage. Would it be mounted inside or outside the garage?

I understand the stupidity of the question...spare me.

They’re supposed to have screens to prevent critters from getting in.

around here some people close all the foundation vents and put a de-humidifier in the crawl space.

this. Probably wanted to keep the ac and/or humidity down in the garage so they sealed it in and put a dehumidifier or ac in there.

Is it a foundation vent or a flood vent?

Looks like it's too high on the wall to be a vent for a crawl space. I'm also assuming the concrete apron under the garage door continues to a concrete floor inside - slab on grade, no crawlspace. They look too big to be weep holes to drain water that gets inside the wall. And, since it looks like block on the exterior and not brick, there probably isn't a space to drain with weep holes anyway.

I have no idea what those "vents" would even be for.

Bad angle view in photo's but I'd put my money on "flood vents". They are now required on anything in the flood zone. They claim they reduce damage in a flood situation.

Flood vents are mounted 2-3” above the inside floor level. Becoming very common in flood zones. They have very large openings so they don’t clog. Mine are a door that is closed and when the water rises floats open.

Here in Ohio I seal my crawlspace vents every October with foam and then open them up once it consistently stays in the 40s at night, so that I don't get any frozen pipes.

Those are air vents for the garage so if you are running your vehicle inside it van release the gasses. Peiple seal them if they enclose the garage or in the winter. Also need to have them if you have gas appliances in the garage
