Sunday is a day of rest. So you are not allowed to make noise that disturbs others. If your windows are fully covered, you can also make some noise as long as it is no longer audible outside.
Not causing noise pollution is the most important thing.
Vacuuming would also be forbidden if your vacuum cleaner is loud and your windows are open.
That you “work” yourself on Sundays, you would have to tell your pastor during confession, but the regulatory office is not interested.
Paid handyman work is of course forbidden on Sundays and would then be illegal work, unless you have an official exemption permit.
There are occasionally neighbors who are already disturbed by the sight and then prick up their ears, so even the smallest noise suddenly becomes annoying. This mainly happens with well-off older generations. A privacy screen helps against this, although you would be legally in the clear.
