Hello and thanks for your help.
I want to know if I need planning permission to add a window? It is for a bathroom. The tenant has said to install a window because of moisture. I said I would do a fan, but a window would be better for the building and the tenant and I agree. The building is damp when I have inspected, so a window would be preferbale if affordable and can get permission.
The laws say that every bathroom has to have a fan or a window so do I need to get planning permission if it is the law? Or is it ok to go ahead?
