Looks like some subpar drywall work. Seems like it’s all cosmetic. You might be able to sand down many of those bumps yourself and then repaint.

Thank you!!

Sand, spackle, sand, prime, paint. If your cracks have some depth, first open up the cracks prior to spackling. And, take your time!

Some of that is going to be normal with settlement and contraction of the mud. But all easily fixable.

That doesnt look like it just happened, it could be settlememt or it could be from water.

Thanks everyone!!

Your gonna have to scrape it down , pre fill , retape and then mud and sand . This is normal even on fairly new houses. skip the the taping and there is a good chance cracks will telegragh through again . The trim job on the window at the countertop looks horrible.
