Looks like mold. You need to find the source of the water leak.

Mold. What room is right above the garage? Get that checked out asap. Probably a leak somewhere

That was there when you had the home inspection. Did it not get mentioned in the report or seen when you looked at the house?

As others say, that's mold from a likely water leak in that area above the garage. If there's nothing above the garage, then the roof might be leaking. This should have been noted in the inspection.

Cut out the drywall. I'd remove the two sheets it seems to be limited to or you can cut out the impacted area. Then find the source of the leak, have it repaired and then replace the drywall. Seams in the garage need to be taped and mudded to prevent polluted air from the garage getting into your home.

Or the inspection was done with the garage door open, effectively covering up that spot. Wouldn't be the first time an inspector didn't think to close the door...

Or it developed after the inspection. I only takes about 48 hours for mold to start growing on wet drywall.

That mold is months or years old. Cut out the drywall, there will be more on the framing. Fix the leak. New drywall. Wear PPE.

It’s mold , but is the area still wet? If not it’s possible the leak was fixed. Either way id cut that section out and see what’s behind it and the replace the rotted section.

Mold. Cut it out and check for water leaks.

Probably mould. And since there is generally no water pipes above the garage as I assume there is no room over the garage or just a bedroom, then the leak is likely condensation on the ductwork due to insufficient insulation and high humidity or leak from the roof, possibly if you have a small overhang roof over the garage. Since the leak does not seem to be large, could be leak the eavestrough/soffit or condensation. You will need to replace the drywall, possibly some wood and the insulation too - after you find out what caused the leak.

I can't imagine what it looks like on the other side of the drywall. Please wear a mask when cutting that out.

Take some pictures and post them after you open up the ceiling to look around.

I see new drywall and old drywall on that ceiling. I think the leak was repaired but the repair was done incorrectly and the leak was never fixed.
The fact that a home inspector missed this is sad. Or possibly the OP is a tenant.

Very good point, it's been "fixed" already. Bottom right of pic, the old drywall. Contrast with the patch that is moldy. The story lies above.

Meh, unless you have some immunity issues, the drywall dust is more problematic than some mold.

My guess is it's a result of a poorly sealed and badly insulated duct to a room over the garage. Air seepage combined with running the A/C constantly in the summer led to this.

So there's no room above the garage? That it totally mold build up. Water ALWAYS finds the lowest point to pool at, so if there is no room above the garage, either your garage roof is leaking or it's coming from a leak between the joint from your garage and your house. If the flashing is worn out or has a leak that might be where it's coming from.
