I would think you would get a lot of noise complaints from occupants in Henderson.

Most likely he has a busy and hectic life ( knowing the plumber grind).

I also like the idea of a handheld grinding wheel with the right blade @Matt Motil.

I believe you can charge for the accommodation and for reverting the change down the road up front.You can evict or get rid of the animal if it poses a threat, violates any noise ordinances, is destructive to the property and things like that.   

They have decibel readers on Amazon and counties have noise ordinances, don't go over them but it is not illegal to go right up to them. 

You can't charge a deposit, rent, or anything else.However, you are allowed to enforce rules regarding noise, keeping the animal under control, cleaning up after it, etc.

@Kai Van LeuvenDo you have any issues with the tenant living next to the laundry room complaining about noise of machines or tenants coming/going?

Common charges often relate to landscaping, exterior modifications, noise disturbances, and parking violations, reflecting the HOA's commitment to maintaining a harmonious and aesthetically pleasing environment.

The grind was OK for me until I had kids and realized how little of their life I was witnessing.

Everyone I know had to grind through it.
