I feel for you. My life has become unbearable since these creeps moved in next door (duplex, so we share a wall). I swear the husband is running an illegal furniture factory in there, he has power tools running for 6-8 hours a day, sometimes more. I work from home, so you can imagine how difficult it is to concentrate with the noise.

We could complain, as it looks like they are violating the noise ordinance, as well as operating a business without a permit. I am sure it violates their lease too. However, these are seriously scary people, we worry about retaliation. And, fingers crossed, we should be moving very soon.

In your case, if you plan to live there for a while, then I agree with the previous poster as far as checking with your local authorities. Most likely there is some sort of noise ordinance. I hope you can get some relief. I know how annoying it is!
