Multi unit rental property, one unit not rented, not used for personal use. Question on topic

I live in a home with 3 units.  I live in one, rent the other two.  One of the other units was not rented in 2023, but needed some repairs... due to Covid finding a contractor to do work in my small town is impossible.  If I didn't use it for personal use, but it was not rented, and not really available for rent how to do I treat this on my taxes?  I normally depreciate my rental portion of the property and still have to pay expenses, like sewer and utilities.  Are these expenses deductible?
